Description

MODULAR UPPER EXTREMITY CONTRACTURE COUNTERACTING ORTHOTIC SYSTEM AND METHODS OF USE CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present Patent Application claims the benefit of pending U.S. provisional patent application 62/986,912, filed on March 9, 2020. INCORPORATION BY REFERENCE [0002] United States Provisional Patent Application No.62/986,912, filed on March 9, 2020, is specifically incorporated by reference herein as if set for in its entirety. TECHNICAL FIELD [0003] The present disclosure relates to modular orthotic systems for counteracting contracture in the upper extremities of a wearer, and associated methods of assembling, operating, and use of these components and systems. BACKGROUND [0004] Every year in the United States alone, more than 795,000 people experience a stroke. Of these attacks, about 87% are ischemic strokes, in which blood flow to the brain is blocked. About 25 to 43% of ischemic stroke survivors experience spasticity–the stiffening and tightening of muscles–within the first year following their brain injury. Muscle tone is the natural tension, or contraction, in a muscle that resists stretching. Stroke may cause an abnormal increase in muscle tone, leading to spasticity, and this contraction of the muscles may range from mild muscle stiffness to severe pain or spasms. Over time, this spasticity can cause the muscles to physically shorten and shrink, and can result in fixed joints, called contracture. Though less common, other conditions besides stroke, such as mechanical injury or neurological conditions such as congenital spastic paraplegia, spinal cord injury, and traumatic brain injury may also cause spasticity. [0005] Stroke survivors often experience this spasticity and resulting contracture in their fingers, hands, wrists, elbows, and shoulders, as the muscles contract and pull the joints inward into a folded position against the chest, though spasticity can also occur in hips, knees, ankles, feet, and toes. For patients experiencing spasticity and contracture in their upper extremities, everyday movements such as reaching and grasping can become difficult, painful, and increasingly impossible as their condition worsens, and can interfere with ordinary tasks and personal hygiene. [0006] Regular movement, exercise, and stretching in wide ranges of motion are helpful to ease muscle tightening and prevent muscle shortening following stroke. For patients who have experienced more severe hemorrhagic or ischemic strokes, however, these preventative measures may not be sufficient to prevent the rapid tightening of their muscles and curling in of their limbs. Patients with more advanced contracture often rely on braces or splints to attempt to hold their limbs in place or stretch the affected muscles. While spasticity following stroke is irreversible, contracture can be counteracted with the use of therapeutic orthotic devices. [0007] The Saebo^TM Flex, for example, is an orthotic product that uses finger splints connected to a wrist brace by a series of spring systems to extend and stretch the wearer’s fingers. This brace is worn therapeutically for several sessions each day in an effort to counteract contracture over time. The Neuro-IFRAH^® custom orthotics systems similarly attempt to address contracture with various arm, wrist, and hand braces intended to hold the wearer’s extremities in a fixed, extended position. [0008] Braces like these systems require a relatively mild stage of contracture, however, and are unable to address the unique difficulties experienced by stroke survivors with more advanced stages of contracture. For these patients, the spasticity following stroke has caused their wrists, hands, and fingers to curl inwardly too much to even attach the finger braces or secure the hand paddles to begin a therapeutic treatment. A more acute treatment system is needed to address these advanced stages of contracture in gradual stages. SUMMARY [0009] Applicant has recognized an unmet need for an upper extremity orthotic system that addresses the particular needs of stroke survivors with advanced stages of contracture. [0010] The contracture counteracting orthotic system described herein addresses the previously unsolved problems of existing orthotic braces by providing a modular device that gradually and incrementally stretches contracted muscles in any combination of the wearer’s fingers, hand, wrist, elbow, and shoulder through the use of a series of increasingly aggressive bracing components and positions. By providing a modular orthotic system, the individual needs of stroke survivors can be addressed at any stage of spasticity, and therapeutic treatment can progress as appropriate for that individual. Additionally, the interchangeable nature of the modular system described herein allows for wearers to control their therapeutic sessions independently. [0011] According to an embodiment, an upper extremity contracture counteracting orthotic system is described. The system may include a forearm stabilizing component, a connecting joint connected at a proximal end thereof to the forearm stabilizing component, and two or more fingers and hand extension components. The forearm stabilizing component may include an elongate rigid member positioned to receive a forearm of a wearer on an upper surface thereof, and a plurality of securing members positioned to extend transversely from the elongate rigid member and to substantially encircle and secure the forearm of the wearer when positioned thereon. The connecting joint may have a connector component positioned at a distal end thereof, the connector component positioned to be complementary to a connector channel positioned on each of two or more fingers and hand extension components. Each of the two or more fingers and hand extension components may be positioned to alternately connect to the forearm stabilizing component via the complementary connector component and the connector channel, each of the two or more fingers and hand extension components positioned to receive a hand of the wearer and thereby to extend and stretch the fingers and hand of the wearer when positioned thereon. [0012] In an embodiment, the connecting joint may further include a ratcheting joint. The ratcheting joint is positioned to allow controlled incremental upward rotation of each of the two or more fingers and hand extension components into a horizontal alignment with the forearm stabilizing component thereby to stretch a wrist of the wearer when positioned thereon, without allowing downward rotation of each of the two or more fingers and hand extension components back towards the forearm stabilizing component. [0013] In an embodiment, the fingers and hand extension components may be selected from any of a cone fingers and hand extension component, a clam fingers and hand extension component, and a paddle fingers and hand extension component. [0014] In an embodiment, the cone fingers and hand extension component may include a conical member tapered between a narrow end and a wide end and positioned to extend transversely with respect to the forearm stabilizing component when connected to the forearm stabilizing component via the connecting joint; and the connector channel extending along a length of the conical member and positioned to be complementary to the connector component extending from the connecting joint so as to slidably connect the cone fingers and hand extension component to the forearm stabilizing component such that the cone fingers and hand extension component is positioned to slide laterally in the hand of the wearer from the narrow end to the wide end so as to extend and stretch the fingers and the hand of the wearer when positioned thereon. [0015] In an embodiment including the cone fingers and hand extension component, the connector component may be positioned to incrementally slide along the connector channel in a direction from the narrow end of the conical member to the wide end of the conical member and to prevent sliding in a direction from the wide end of the conical member to the narrow end of the conical member. [0016] In an embodiment, the clam fingers and hand extension component may include an arcuate surface positioned to receive fingers of the wearer along an upper portion of the arcuate surface and a thumb of the wearer along a lower portion of the arcuate surface; and the connector channel positioned to be complementary to the connector component extending from the connecting joint so as to securely connect the clam fingers and hand extension component to the forearm stabilizing component. [0017] In an embodiment, the paddle fingers and hand extension component may include a first flat surface positioned to receive a palm and fingers of the wearer thereon; a second flat surface positioned to extend substantially transversely to the first flat surface and positioned to receive a thumb of the wearer thereon; a second plurality of securing members positioned to extend outwardly from the paddle fingers and hand extension component and to substantially encircle one or more portions of the wearer’s hand so as to secure the paddle fingers and hand extension component to the wearer’s hand when positioned thereon; and the connector channel positioned to be complementary to a connector component extending from the connecting joint so as to securely connect the paddle fingers and hand extension component to the forearm stabilizing component. [0018] In an embodiment, the upper extremity orthotic system may include a wrist pronation and supination correction component connected to the elongate rigid member of the forearm stabilizing component, the wrist pronation and supination correction component having a ratcheting strap positioned to at least partially encircle the wearer’s wrist when positioned thereon and positioned to allow incremental rotation of the wearer’s wrist with respect to the forearm stabilizing component in a single direction, so as to facilitate correction of pronation or supination of the wearer’s wrist when positioned thereon. [0019] In an embodiment, the upper extremity orthotic system may include an upper arm stabilizing component. The upper arm stabilizing component may include an elongate rigid member, a plurality of securing members, and a ratcheting joint. The elongate rigid member may be positioned to receive an upper arm of the wearer on an upper surface thereof. The plurality of securing members may be positioned to extend transversely from the elongate rigid member to substantially encircle and secure the upper arm of the wearer when positioned thereon. The ratcheting joint may extend from the upper arm stabilizing component to the forearm stabilizing component, and positioned to allow controlled incremental downward rotation of the forearm stabilizing component into vertical alignment with the upper arm stabilizing component thereby to stretch an elbow of the wearer when positioned thereon. [0020] In an embodiment, the upper extremity orthotic system having an upper arm stabilizing component may further include a shoulder stabilizing component. The shoulder stabilizing component may include a shoulder securing member and an elongate strap member. The shoulder stabilizing member may be positioned to at least partially encircle a shoulder of the wearer opposite to the upper arm of the wearer on which the upper arm stabilizing component is positioned when positioned thereon. The elongate strap member may be positioned to stretchably connect the shoulder securing member to the upper arm stabilizing component. The elongate strap member has an adjustable length so as to allow a shoulder of the wearer connected to the upper arm on which the upper arm stabilizing component is positioned to be incrementally rotated backward and stretched to counteract contracture when positioned thereon. [0021] The present disclosure also is directed to methods for counteracting contracture in an upper extremity of a wearer. One such method includes attaching a first stage fingers and hand extension component to a forearm stabilizing component via a connecting joint, the connecting joint having a connector component positioned at a distal end thereof, the connector component positioned to be complementary to a first connector channel positioned on the first stage fingers and hand extension component, the first stage fingers and hand extension component positioned to receive a hand of the wearer and to extend and stretch the fingers and the hand of the wearer when positioned thereon. The forearm stabilizing component may include an elongate rigid member positioned to receive a forearm of a wearer on an upper surface thereof, and a plurality of securing members positioned to extend transversely from the elongate rigid member and to substantially encircle and secure the forearm of the wearer when positioned thereon. In an embodiment, the method further may include removing the first stage fingers and hand extension component from the forearm stabilizing component via the connector component and the first connector channel after a first predetermined period of time. The method further may include attaching a second stage fingers and hand extension component to the forearm stabilizing component via the connector component and a second connector channel, the connector component positioned to be complementary to the second connector channel positioned on the second stage fingers and hand extension component, the second stage fingers and hand extension component positioned to receive the hand of the wearer and to further extend and stretch the fingers and the hand of the wearer when positioned thereon. [0022] In an embodiment, the method may include removing the second stage fingers and hand extension component from the forearm stabilizing component via the connector component and the second connector channel after a second predetermined period of time. The method further may include attaching a third stage fingers and hand extension component to the forearm stabilizing component via the connector component and a third connector channel, the connector component positioned to be complementary to the third connector channel positioned on the third stage fingers and hand extension component, the third stage fingers and hand extension component positioned to receive the hand of the wearer and to further extend and stretch the fingers and hand of the wearer when positioned thereon. [0023] In an embodiment, the method further may include incrementally rotating a ratcheting joint positioned to extend from the forearm stabilizing component to one of the first, second, or third stage fingers and hand extension components, the ratcheting joint positioned to allow controlled incremental upward rotation of one of the first, second, or third stage fingers and hand extension components into horizontal alignment with the forearm stabilizing component thereby to stretch the wrist of the wearer when positioned thereon. [0024] In an embodiment, the first stage fingers and hand extension component may include a cone fingers and hand extension component. In an embodiment, the cone fingers and hand extension component may include a conical member and the first connector channel. The conical member may be tapered between a narrow end and a wide end and positioned to extend transversely with respect to the forearm stabilizing component when connected to the forearm stabilizing component via the connecting joint. The first connector channel may extend along a length of the conical member and positioned to be complementary to the connector component extending from the connecting joint so as to slidably connect the cone fingers and hand extension component to the forearm stabilizing component such that the cone fingers and hand extension component is positioned to slide laterally in the hand of the wearer from the narrow end to the wide end so as to extend and stretch the fingers and hand of the wearer when positioned thereon. In an embodiment, the connector component may be positioned to incrementally slide along the connector channel in a direction from the narrow end of the conical member to the wide end of the conical member and to prevent sliding in a direction from the wide end of the conical member to the narrow end of the conical member. [0025] In an embodiment, the second stage fingers and hand extension component and the third stage fingers and hand extension component may be selected from one of a clam fingers and hand extension component and a paddle fingers and hand extension component. [0026] In an embodiment, the method may include attaching an upper arm stabilizing component to the forearm stabilizing component. The upper arm stabilizing component has an elongate rigid member positioned to receive an upper arm of the wearer on an upper surface thereof, and a plurality of securing members positioned to extend transversely from the elongate rigid member to substantially encircle and secure the upper arm of the wearer when positioned thereon. In an embodiment, the method further may include incrementally rotating a ratcheting joint positioned to extend from the upper arm stabilizing component to the forearm stabilizing component, the ratcheting joint positioned to allow controlled incremental downward rotation of the forearm stabilizing component into vertical alignment with the upper arm stabilizing component thereby to stretch an elbow of the wearer when positioned thereon. [0027] In an embodiment, the method further may include connecting a wrist pronation and supination correction component to the elongate rigid member of the forearm stabilizing component, the wrist pronation and supination correction component positioned to include a ratcheting strap positioned to at least partially encircle the wearer’s wrist when positioned thereon. In an embodiment, the method further may include incrementally rotating the wrist pronation and supination correction component with respect to the forearm stabilizing component in a single direction, so as to facilitate correction of pronation or supination of the wearer’s wrist when positioned thereon. [0028] In an embodiment, the method further may include connecting a shoulder stabilizing component to the upper arm stabilizing component, and incrementally shortening a length of an elongate strap member of the shoulder stabilizing component, the elongate strap member positioned to extend between the upper arm stabilizing component and a shoulder securing member positioned to at least partially encircle a shoulder of the wearer opposite to the arm of the wearer on which the upper arm stabilizing component is positioned, so as to allow a shoulder of the wearer connected to the upper arm on which the upper arm stabilizing component is positioned to be incrementally rotated backward and stretched to counteract contracture when positioned thereon. [0029] The present disclosure is also directed to upper extremity contracture counteracting orthotic kits. In an embodiment, the kit may include a container positioned to contain components of an upper extremity contracture counteracting orthotic system.

DETAILED DESCRIPTION [0075] Various upper extremity contracture counteracting orthotic systems, and methods for assembling and operating the same, are disclosed to illustrate various examples that may be employed to achieve one or more desired improvements. The described embodiments are examples only and are not intended to restrict the general disclosure presented and the various aspects and features of this disclosure. The general principles described herein may be applied to embodiments and applications other than those discussed herein without departing from the spirit and scope of the disclosure. This disclosure should be afforded the widest scope consistent with the principles and features that are disclosed or suggested herein. [0076] Although certain aspects, advantages, and features are described herein, it is not necessary that any particular embodiment include or achieve any or all of those aspects, advantages, and features. For example, some embodiments may not achieve the advantages described herein, but may achieve other advantages instead. No feature, component, or step is necessary or critical. [0077] An embodiment of the present disclosure is directed to an upper extremity contracture counteracting orthotic system 100, for example as illustrated in FIG. 1. The system 100 may include a forearm stabilizing component 105, a connecting joint 120, and two or more fingers and hand extension components, selected from any of a cone fingers and hand extension component 135, a clam fingers and hand extension component 235, and a paddle fingers and hand extension component 335. The forearm stabilizing component 105 may include an elongate rigid member 110 positioned to receive a forearm of a wearer on an upper surface thereof. For example, the elongate rigid member 110 may be a formed plastic or other suitably rigid or semi-rigid material that partially encircles the wearer’s forearm to secure the wearer’s forearm to the forearm stabilizing component 105. In some embodiments, for example as illustrated in FIG.1, the elongate rigid member 110 may include a series of holes or perforations to enhance comfort, circulation, and breathability of the device during use. A plurality of securing members 115 may be positioned to extend transversely from the elongate rigid member 110 and to substantially encircle and secure the forearm of the wearer when positioned thereon. For example, the securing members 115 may include a series of Velcro straps positioned to loop across the top of the wearer’s forearm to secure the arm to the elongate rigid member 110. In other embodiments, other suitable securing members 115, such as elastic bands, metal or plastic clips or latches, or the like, are contemplated, as would be understood by a person having ordinary skill in the art. A connecting joint 120 may be positioned to extend from the forearm stabilizing component 105 at a proximal end thereof, proximate to the wearer’s wrist. The connecting joint 120 may include a connector component 125 positioned at a distal end thereof, and shaped and oriented to be complementary to a connector channel 140, 240, 340 positioned on each of the fingers and hand extension components 135, 235, 335, respectively. In the illustrated example, the connector component 125 and the connector channel 140, 240, 340 connect via a t-channel connection, while in other embodiments, other complementary connection means are contemplated, as would be readily understood by one of ordinary skill in the art. As illustrated in FIG. 1 and discussed further herein, the connector component 125 may be configured to slidably connect with the connector channel 140 of the cone fingers and hand extension component 135 so as to allow lateral movement of the cone portion through the wearer’s palm from a wide end 137 to a narrow end 139. In certain embodiments, the connector component 125 may be configured to statically connect with the connector channels 240, 340 of the clam fingers and hand extension component 235 and the paddle fingers and hand extension component 335, respectively, so as to secure the fingers and hand extension components 235, 335 to the forearm stabilizing component 105 without permitting movement therebetween. [0078] In this way, the connecting joint 120 may facilitate modular connection of one or more stages of fingers and hand extension components 135, 235, 335 according to individual patient needs, such as degree of spasticity and contracture, physical therapy regimen, and the like. The interchangeable nature of the connecting joint 120 with the various fingers and hand extension components 135, 235, 335 may even allow substitution of different stages or phases of fingers and hand extension components 135, 235, 335 autonomously by the wearer, without the need to remove the forearm stabilizing component 105. The configuration of the connector component 125 and connector channel 140, 240, 340 may permit the wearer to remove a first stage fingers and hand extension component 135, 235, 335 and attach one or more second stage fingers and hand extension components 135, 235, 335 with the hand unaffected by stroke, without the need for caregiver assistance. This one-handed operability and modular capability represents a marked improvement over structurally complex and single-phase braces known in the art. [0079] A method for counteracting contracture in an upper extremity of a wearer, according to an embodiment of the present disclosure, may include attaching a first stage fingers and hand extension component 135, 235, 335 to a forearm stabilizing component 105 via a connecting joint 120. The method may further include removing the first stage fingers and hand extension component 135, 235, 335 from the forearm stabilizing component 105 via the connector component 125 and the complementary connector channel 140, 240, 340 after a first predetermined period of time. In some examples, this first stage fingers and hand extension component may be the cone fingers and hand extension component 135, particularly if the wearer has experienced severe spasticity and contracture as a result of the stroke. In other embodiments, the first stage fingers and hand extension component may be either of the clam or paddle fingers and hand extension components 235, 335, depending on the individual physiological and therapeutic needs of the wearer. [0080] After using the first stage fingers and hand extension component 135, 235, 335 for a first predetermined period of time sufficient to achieve the wearer’s therapeutic goals in stretching the wearer’s fingers and hand, the method may include attaching a second stage fingers and hand extension component 135, 235, 335 to the forearm stabilizing component 105 via the connector component 125 and complementary connector channel 140, 240, 340. The second stage fingers and hand extension component 135, 235, 335 may be positioned to receive the hand of the wearer and to further extend and stretch the fingers and hand of the wearer when positioned thereon. [0081] In some examples, the wearer may progress from a cone fingers and hand extension component 135 as the first stage and to a clam fingers and hand extension component 235 as the second stage. In other embodiments, for example where the wearer has experienced a lesser degree of spasticity and contracture, the wearer may progress from a clam fingers and hand extension component 225 as the first stage of treatment to a paddle fingers and hand extension component 335 as the second stage. Other combinations and progressions between each of the fingers and hand extension components 135, 235, 335 are contemplated, enabling the therapeutic process to be tailored to the individual stroke survivor’s physiological needs, as will be readily understood by one of ordinary skill in the art. [0082] In some embodiments, the wearer may require three stages of treatment with fingers and hand extension components 135, 235, 335, and the method may include removing the second stage fingers and hand extension component 135, 235, 335 from the forearm stabilizing component 105 via the connector component 125 and the complementary connector channel 140, 240, 340 after a second predetermined period of time, and attaching a third stage fingers and hand extension component 135, 235, 335 to the forearm stabilizing component 105 via the connector component 125 and the complementary connector channel 140, 240, 340. The wearer may maintain the third stage fingers and hand extension component 135, 235, 335 for a third predetermined period of time so as to maximize the therapeutic efficacy of the component. The connecting joint 120 further may include a ratcheting joint 130, positioned to allow controlled incremental upward rotation of each of the fingers and hand extension components 135, 235, 335 when connected to the forearm stabilizing component 105, in order to bring the fingers and hand extension components 135, 235, 335 from a bent position into horizontal alignment with the forearm stabilizing component 105. Although described herein as a ratcheting joint 130, in some embodiments, a clutch joint or a spring-loaded, manually locking joint are also envisioned, as will be readily understood by one of ordinary skill in the art. Simultaneously or sequentially with the stretching of the wearer’s fingers and hand through use of one or more of the fingers and hand extension components 135, 235, 335, the ratcheting joint 130 may facilitate stretching of the wearer’s wrist from a downwardly bent position into a stretched position, aligned with the wearer’s forearm. In particular, the ratcheting joint 130 may allow controlled incremental upward rotation of each of the fingers and hand extension components 135, 235, 335 into horizontal alignment with the forearm stabilizing component 105 thereby to stretch the wearer’s wrist when positioned thereon, without allowing downward rotation of the fingers and hand extension components 135, 235, 335 back towards the forearm stabilizing component 105. In this way, the wearer’s wrist may be incrementally stretched and held for predetermined periods of time during therapeutic use. [0083] In an embodiment, a method for counteracting contracture in an upper extremity of a wearer may include incrementally rotating a ratcheting joint 130 positioned to extend from the forearm stabilizing component 105 to one of the first, second, or third stage fingers and hand extension components 135, 235, 335, the ratcheting joint 130 positioned to allow incremental upward rotation of one of the first, second, or third stage fingers and hand extension components 135, 235, 335 into horizontal alignment with the forearm stabilizing component 105 thereby to stretch the wrist of the wearer when positioned thereon. [0084] As illustrated in FIGS.2a-2f, the connecting joint 120 may facilitate the interchange of two or more stages of fingers and hand extension components 135, 235, 335 during the course of the wearer’s therapeutic use. In particular, the connector component 125 may be configured to be complementary to a connector channel 140, 240, 340 positioned on each of the fingers and hand extension components 135, 235, 335. For example, as illustrated in the embodiment 200a shown in FIG. 2a, the connector component 125 of the forearm stabilizing component 105 and the connector channel 140 of the cone fingers and hand extension component 135 may be configured to be complementary as a sliding T-channel connection. In other embodiments, other complementary connection means are contemplated, as will be readily understood by one of ordinary skill in the art. In an embodiment, the connector component 125 may be positioned to enter the connector channel 140 of the cone fingers and hand extension component 135 at a wide end 137 of the cone portion, and slide inwardly toward the narrow end 139, as illustrated in the embodiment 200b shown in FIG.2b. [0085] After the wearer has completed therapeutic use of the cone fingers and hand extension component 135 as illustrated in FIGS.2a-b, the cone fingers and hand extension component 135 may be removed from the forearm stabilizing component 105 and a second phase fingers and hand extension component 235, 335 may be attached to the forearm stabilizing component 105. FIGS. 2c-2d illustrate an embodiment in which a clam fingers and hand extension component 235 is attached to the forearm stabilizing component 105, while FIGS.2e-2f illustrate an embodiment in which a paddle fingers and hand extension component 335 is attached to the forearm stabilizing component 105. In various embodiments and therapeutic treatment regimens, any order or combination of the cone, clam, and paddle fingers and hand extension components 135, 235, 335 may be utilized with the forearm stabilizing component 105. For example, wearers with lesser degrees of spasticity and contracture may begin with the clam fingers and hand extension component 235 and progress to the paddle fingers and hand extension component 335, while wearers with greater degrees of spasticity and contracture may begin with the cone fingers and hand extension component 135 and progress through each stage of the clam fingers and hand extension component 235 and the paddle fingers and hand extension component 335. In an embodiment, the two or more stages of fingers and hand extension components are all cone fingers and hand extension component 135 of various diameters or thickness. In some embodiments in which the wearer has extreme contracture, the first stage fingers and hand extension component 135 may include a cone having a smaller diameter so as to minimally stretch the wearer’s fingers and hand, and the second phase fingers and hand extension component 135 may include a cone having a larger diameter. Other therapeutic progressions and combinations are also contemplated, as will be readily understood by one of ordinary skill in the art. [0086] FIG.2c illustrates an embodiment 200c in which the connector component 125 of the connecting joint 120 is complementary to the connector channel 240 of the clam fingers and hand extension component 235. Unlike the connector channel 140 of the cone fingers and hand extension component 135, which allows for sliding of the connector component 125 along the connector channel 140, the connector channel 240 of the clam fingers and hand extension component 235 may allow the connector component 125 to lock into the connector channel 240 in a stationary manner, as illustrated in the embodiment 200d of FIG.2d. [0087] FIG.2e illustrates an embodiment 200e in which the connector component 125 of the connecting joint 120 is complementary to the connector channel 340 of the paddle fingers and hand extension component 335. Similar to the connector channel 240 of the clam fingers and hand extension component 235, but unlike the connector channel 140 of the cone fingers and hand extension component 135, which allows for sliding of the connector component 125 along the connector channel 140, the connector channel 340 of the paddle fingers and hand extension component 335 may allow the connector component 125 to lock into the connector channel 340 in a stationary manner, as illustrated in the embodiment 200f of FIG.2f. [0088] FIGS.3-7 illustrate various views of an example embodiment 300 of a cone fingers and hand extension component 135. FIG. 3 is a perspective view of an upper extremity contracture counteracting orthotic system having a cone fingers and hand extension component. FIG. 4 is a left side view of an upper extremity contracture counteracting orthotic system having a cone fingers and hand extension component. FIG.5 is a right side view of an upper extremity contracture counteracting orthotic system having a cone fingers and hand extension component. FIG. 6 is a top view of an upper extremity contracture counteracting orthotic system having a cone fingers and hand extension component. FIG. 7 is a bottom view of an upper extremity contracture counteracting orthotic system having a cone fingers and hand extension component. As discussed above, in an embodiment, a forearm stabilizing component 105, having an elongate rigid member 105 and a plurality of securing members 115, may include a connecting joint 120 having a connector component 125 positioned at a distal end thereof and positioned to be complementary to a connector channel 140 of the cone fingers and hand extension component 135. The cone fingers and hand extension component 135 may include a conical member tapered between a narrow end 139 and a wide end 137, and positioned to extend transversely with respect to the forearm stabilizing component 105 such that the cone fingers and hand extension component 135 is positioned to slide laterally in the hand of the wearer from the narrow end 139 to the wide end 137 so as to extend and stretch the fingers and hand of the wearer when positioned thereon. [0089] The conical member of the cone fingers and hand extension component 135 may be formed of a rigid or semi-rigid plastic, composite, or other suitable material, as will be readily understood by one of ordinary skill in the art. The size and tapered shape of the cone may be selected to optimize gradual stretching of the wearer’s fingers and hand from a most contracted position to a less contracted position. [0090] The connector component 125 of the connecting joint 120 of the forearm stabilizing component 105 may be configured to be complementary to the connector channel 140 of the cone fingers and hand extension component 135 such that the connector component 125 may be insertable into the connector channel 140 to slidably secure the cone fingers and hand extension component 135 to the forearm stabilizing component 105. In order to stretch the contracted fingers and hand of the wearer, the connector component 125 may be positioned to slide laterally along the connector channel 140 from the narrow end 139 to the wide end 137 of the conical member of the cone fingers and hand extension component 135. In an embodiment, the connector component 125 may be positioned to incrementally slide along the connector channel 140 in the direction from the narrow end 139 to the wide end 137 of the conical member and to prevent sliding backward, in a direction from the wide end 137 to the narrow end 139 of the conical member. This may be achieved with a ratcheting connection in some embodiments, or by any other suitable means as will be readily understood by one of ordinary skill in the art. In this way, a wearer may gradually stretch his fingers and hand by incrementally sliding the conical member through his hand and holding the stretch at each increment for a predetermined period of time for therapeutic efficacy before further sliding the conical member to further stretch his fingers and hand. [0091] This incremental sliding of the conical member through the wearer’s hand so as to gradually stretch the wearer’s fingers and hand is illustrated, for example, in FIGS.17a, 17b, and 17c. In the embodiment 1700a illustrated in FIG. 17a, for example, the wearer is gripping the narrow end 139 of the conical member for minimal stretching. In the embodiment 1700b illustrated in FIG. 17b, the wearer has slid the conical member slightly within his hand by sliding the connector component 125 within the connector channel 140. As shown, the wearer is now gripping a portion of the conical member that is wider than the narrow end 139, so as to increase the stretch in the wearer’s fingers and hand. FIG.17c illustrates an embodiment 1700c in which the wearer has slid the conical member further within his hand so as to grip a wider portion of the conical member, closer to the wide end 137 of the conical member. This sliding occurs through the complementary connection between the connector component 125 of the forearm stabilizing component 105 and the connector channel 140 of the cone fingers and hand extension component 135. Although illustrated in only three stages 1700a, 1700b, and 1700c, any number of incremental movements may be used to gradually slide the conical member through the wearer’s hand so as to gradually stretch the wearer’s fingers and hand. During therapeutic use, the wearer may hold each incremental position for a predetermined period of time before advancing to a wider grip. [0092] Once the wearer has slid the conical member to the widest point at wide end 137, the wearer then has the option of replacing the cone fingers and hand extension component 135 with a second stage fingers and hand extension component 235 or 335. Depending on the wearer’s level of contraction and personal therapeutic regimen, the wearer may replace the cone fingers and hand extension component 135 with either the clam fingers and hand extension component 235 or the paddle fingers and hand extension component 335. [0093] FIGS.8-11 illustrate an embodiment of a clam fingers and hand extension component 235 secured to a forearm stabilizing component 105. FIG. 8 is a perspective view of an upper extremity contracture counteracting orthotic system having a clam fingers and hand extension component. FIG. 9 is a left side view of an upper extremity contracture counteracting orthotic system having a clam fingers and hand extension component. FIG. 10 is a right side view of an upper extremity contracture counteracting orthotic system having a clam fingers and hand extension component. FIG. 11 is a top view of an upper extremity contracture counteracting orthotic system having a clam fingers and hand extension component. The clam fingers and hand extension component 235 may include an arcuate surface positioned to receive the fingers of the wearer along an upper portion of the arcuate surface and the thumb of the wearer along a lower portion of the arcuate surface. As with the conical member of the cone fingers and hand extension component 135, the arcuate surface of the clam fingers and hand extension component 235 may be formed of a rigid or slightly flexible plastic or composite material, or any other suitable rigid or semi-rigid material as will be readily understood by one of ordinary skill in the art. The arcuate shape may be sized and configured to fit into the wearer’s palm so as to statically stretch the fingers and hand of the wearer when positioned thereon. Unlike the cone fingers and hand extension component 135, the clam fingers and hand extension component 235 may be configured to statically stretch the wearer’s fingers and hand, without any movement. A wearer may don the forearm stabilizing component 105 and clam fingers and hand extension component 235 for a predetermined period of time selected according to the wearer’s therapeutic regimen, for example for three, 20-60 minute sessions per day, or for any other suitable period of time as will be readily understood by one of ordinary skill in the art. In an embodiment, the two or more stages of fingers and hand extension components can be two or more clam fingers and hand extension component 135 of various curvatures. [0094] The clam fingers and hand extension component 235 additionally may include a connector channel 240 positioned to be complementary to the connector component 125 extending from the connecting joint 120 of the forearm stabilizing component 105 so as to securely connect the clam fingers and hand extension component 235 to the forearm stabilizing component 105. In the illustrated embodiment, the connector channel 240 and connector component 125 are complementary components of a T-channel connection. A person of ordinary skill in the art will readily recognize that other suitable connection means are also contemplated. Unlike the slidable connection of the connector component 125 and connector channel 140 of the cone fingers and hand extension component 135, the connection between the connector component 125 and connector channel 240 of the clam fingers and hand extension component 235 may be static to allow for secure coupling of the clam fingers and hand extension component 235 to the forearm stabilizing component 105 without permitting movement there between. In some embodiments, the wearer may progress from the cone fingers and hand extension component 135 to the clam fingers and hand extension component 235, then to the paddle fingers and hand extension component 335. In other embodiments, the wearer may progress from the cone fingers and hand extension component 135 directly to the paddle fingers and hand extension component 335, without using the clam fingers and hand extension component 235. In still other embodiments, the wearer may start with the clam fingers and hand extension component 235 and progress to the paddle fingers and hand extension component 335. Other wearers may use only one of the cone, clam, or paddle fingers and hand extension components 135, 235, 335. Various combinations are contemplated based on individual wearers’ levels of contracture and spasticity, and individually tailored therapeutic regimens. [0095] FIGS. 12-15 illustrate an embodiment of a paddle fingers and hand extension component 335. FIG. 12 is a perspective view of an upper extremity contracture counteracting orthotic system having a paddle fingers and hand extension component. FIG.13 is a left side view of an upper extremity contracture counteracting orthotic system having a paddle fingers and hand extension component. FIG.14 is a right side view of an upper extremity contracture counteracting orthotic system having a paddle fingers and hand extension component. FIG.15 is a top view of an upper extremity contracture counteracting orthotic system having a paddle fingers and hand extension component. In the illustrated embodiment, the paddle fingers and hand extension component 335 may include a first flat surface 336 positioned to receive the palm and fingers of the wearer thereon, and a second flat surface 338 positioned to extend substantially transversely to the first flat surface 336 and positioned to receive the wearer’s thumb thereon. Together, the first and second flat surfaces 336, 338 may be configured to generally form the shape of a hand, so as to support the wearer’s palm, fingers, and thumb in a generally planar and naturally extended position. Like the cone and clam fingers and hand extension components 135, 235, the paddle fingers and hand extension component 335 may be formed of a rigid or semi-rigid plastic or composite material, though other suitable rigid or semi-rigid materials are also contemplated, as will be readily understood by one of ordinary skill in the art. [0096] In an embodiment, a plurality of securing straps 334 may be positioned to extend outwardly from the paddle fingers and hand extension component 335 and to substantially encircle one or more portions of the wearer’s hand so as to secure the paddle fingers and hand extension component 335 to the wearer’s hand when positioned thereon. In the illustrated embodiment, the plurality of securing straps 334 extend across the paddle fingers and hand extension component 335 so as to secure the wearer’s palm to the paddle fingers and hand extension component 335 below the wearer’s fingers and thumb. In other embodiments, various other numbers and configurations of securing straps 334 are envisioned, as will be readily understood by one of ordinary skill in the art. For example, 1, 3, or more straps may be utilized to secure the wearer’s hand to the paddle fingers and hand extension component 335. In the illustrated embodiment, the securing straps 334 are formed of a Velcro material to adjustably secure the wearer’s hand to the paddle fingers and hand extension component 335. In other embodiments, other suitable materials such as elastics, ties, flexible plastics, or the like may be utilized, as will be readily understood by one of ordinary skill in the art. [0097] In an embodiment, the paddle fingers and hand extension component 335 also may include a connector channel 340 positioned to be complementary to the connector component 125 extending from the connecting joint 120 of the forearm stabilizing component 105 so as to securely connect the paddle fingers and hand extension component 335 to the forearm stabilizing component 105. Like the clam fingers and hand extension component 225, in the illustrated embodiment, the connector channel 340 and connector component 125 are complementary components of a T-channel connection. A person of ordinary skill in the art will readily recognize that other suitable connection means are also contemplated. Unlike the slidable connection of the connector component 125 and connector channel 140 of the cone fingers and hand extension component 135, the connection between the connector component 125 and connector channel 340 of the paddle fingers and hand extension component 335 may be static to allow for secure coupling of the paddle fingers and hand extension component 335 to the forearm stabilizing component 105 without permitting movement therebetween. [0098] As discussed above, stroke survivors may experience varying levels of spasticity and contracture in their extremities. Commonly, survivors may experience an inward folding of their fingers, hand, wrist, elbow, and shoulder toward their chest as a result of a hemorrhagic or ischemic stroke. In FIG. 16, an example embodiment 1600 of a stroke survivor experiencing contracture and spasticity in his hand 1645, wrist 1650, elbow 1655, and shoulder 1660 is illustrated. In other embodiments, other combinations and degrees of spasticity are possible, and may be experienced in any of the survivor’s extremities, including arms and legs. Additionally, although illustrated throughout this disclosure with respect to the left side of the wearer’s body, either side of the body of a stroke survivor may be affected, and the present disclosure is directed to treatment to either side of the body accordingly. [0099] The present disclosure addresses multiple elements of spasticity with an upper extremity orthotic system. In an embodiment, the fingers and hand extension components 135, 235, 335 may be used to address spasticity and counteract contracture in the wearer’s fingers and hand 1645. Additionally, the forearm stabilizing component 105 and connecting joint 120 may be configured to address spasticity and counteract contracture in the wearer’s wrist 1650. [00100] For example, as illustrated in FIGS.18a, 18b, and 18c, the ratcheting joint 130 of the connecting joint 120 may facilitate the incremental stretching of the wearer’s wrist 1650. In the embodiment 1800a illustrated in FIG.18a, the wearer’s wrist 1650 may be significantly contracted, and the ratcheting joint 130 may be positioned such that the cone fingers and hand extension component 135 is nearly perpendicular to the forearm securing component 105. In the embodiment 1800b illustrated in FIG. 18b, the ratcheting joint 130 has been rotated upwardly to stretch the wearer’s wrist 1650, and to bring the cone fingers and hand extension component 135 more closely into alignment with the forearm securing component 105. FIG. 18c illustrates an embodiment 1800c in which the ratcheting joint 130 has been further upwardly rotated such that the cone fingers and hand extension component 135 is in substantially horizontal alignment with the forearm stabilizing component 105, and the wearer’s wrist 1650 has been fully stretched from its contracted state. Although illustrated in FIGS.18a-18c as occurring in three steps, in other embodiments the stretching may occur in 1, 2, 4, or more incremental steps, as tailored to the individual wearer’s therapeutic regimen, as will be readily understood by one of ordinary skill in the art. [00101] In some embodiments, the wearer’s fingers and hand 1645 may be stretched first by use of one of more fingers and hand extension components 135, 235, 335, and the wearer’s wrist 1650 may be stretched using the ratcheting joint 130 after completion of the fingers and hand 1645 stretching. In other embodiments, the wearer’s fingers and hand 1645 and wrist 1650 may be stretched simultaneously or substantially simultaneously through concurrent use of the fingers and hand extension components 135, 235, 335 and the ratcheting joint 130. For example, FIGS.19a, 19b, and 19c illustrate an example therapeutic process in which the wearer’s fingers and hand 1645 and wrist 1650 are stretched substantially simultaneously. For example, the embodiment 1900a in FIG.19a illustrates the wearer using the cone fingers and hand extension component 135, having a substantially contracted hand 1645 and wrist 1650. The wearer may use the cone fingers and hand extension component 135 to gradually and incrementally stretch his fingers and hand 1645 by sliding the conical member within his hand using the connector component 125 and connector channel 140 mating discussed above. Simultaneously or sequentially with this stretching of the wearer’s fingers and hand, the ratcheting joint 130 may gradually and incrementally stretch his wrist 1650 by rotating the ratcheting joint 130 upwardly. As illustrated in the embodiment 1900b of FIG.19b, the wearer may then replace the cone fingers and hand extension component 135 with the clam fingers and hand extension component 235 so as to continue stretching his fingers and hand 1645, while continuing to simultaneously or sequentially stretch his wrist 1650 with the ratcheting joint 130. The embodiment 1900c illustrated in FIG.19c shows the wearer progressing to the paddle fingers and hand extension component 335 to further stretch his fingers and hand 1645, while simultaneously or sequentially continuing to rotate ratcheting joint 130 so as to stretch his wrist 1650 by bringing the paddle fingers and hand extension component 335 into horizontal alignment with the forearm stabilizing component 105. In this way, the wearer is able to therapeutically stretch his fingers and hand 1645, and wrist 1650 simultaneously or sequentially, in a gradual or incremental manner tailored to his individual physiological needs, all without having to don separate, hard-to-use devices. Other combinations of treatment regimens to tailor the stretching process to the individual wearer’s therapeutic needs are envisioned, as will be readily understood by one of ordinary skill in the art. [00102] FIGS. 20a, 20b, and 20c illustrate embodiments 2000a, 2000b, 2000c in which, in addition to stretching the wearer’s fingers and hand 1645 and wrist 1650, the wearer’s elbow 1655 may additionally be stretched and extended from a contracted position. FIG.20a is a perspective view of a wearer wearing an upper extremity contracture counteracting orthotic system having a cone fingers and hand extension component, a forearm stabilizing component, and an upper arm stabilizing component, in which a ratcheting joint extending between the forearm stabilizing component and the cone fingers and hand extension component is positioned in a most contracted position. And, a ratcheting joint extending between the forearm stabilizing component and the upper arm stabilizing component is positioned in a most contracted position. [00103] FIG. 20b is a perspective view of a wearer wearing an upper extremity contracture counteracting orthotic system having a cone fingers and hand extension component, a forearm stabilizing component, and an upper arm stabilizing component, in which a ratcheting joint extending between the forearm stabilizing component and the cone fingers and hand extension component is positioned in a less contracted position. And, a ratcheting joint extending between the forearm stabilizing component and the upper arm stabilizing component is positioned in a less contracted position. [00104] FIG. 20c is a perspective view of a wearer wearing an upper extremity contracture counteracting orthotic system having a cone fingers and hand extension component, a forearm stabilizing component, and an upper arm stabilizing component, in which a ratcheting joint extending between the forearm stabilizing component and the cone fingers and hand extension component is positioned in a least contracted position. And, a ratcheting joint extending between the forearm stabilizing component and the upper arm stabilizing component is positioned in a least contracted position. [00105] In the illustrated embodiments, the upper extremity orthotic system may include an upper arm stabilizing component 2005, positioned to address spasticity and counteract contracture of the wearer’s elbow 1655. The upper arm stabilizing component 2005 may include an elongate rigid member 2010 positioned to receive an upper arm of the wearer on an upper surface thereof. Similar to the elongate rigid member 110 of the forearm stabilizing component 105, the elongate rigid member 2010 of the upper arm stabilizing component 2005 may be a formed plastic or other suitable rigid or semi-rigid material, formed in an arcuate shape that partially encircles the wearer’s upper arm to secure the wearer’s upper arm to the upper arm stabilizing component 2005. In some embodiments, the elongate rigid member 2010 may include a series of holes or perforations to enhance comfort, circulation, and breathability of the device during use. A plurality of securing members 2015 may be positioned to extend transversely from the elongate rigid member 2010 and to substantially encircle and secure the upper arm of the wearer when positioned thereon. For example, the securing members 2015 may include a series of Velcro straps positioned to loop across the top of the wearer’s upper arm to secure the arm to the elongate rigid member 2010. In other embodiments, other suitable securing members 2015, such as elastic bands, metal or plastic clips or latches, or the like, are contemplated, as would be understood by a person having ordinary skill in the art. [00106] A ratcheting joint 2030 may extend between the upper arm stabilizing component 2005 and the forearm stabilizing component 105 so as to rotatably connect the two components. In the embodiments 2000a, 2000b, 2000c in FIGS.20a-20c, the ratcheting joint 2030 is illustrated being positioned to allow controlled incremental downward rotation of the forearm stabilizing component 105 into vertical alignment with the upper arm stabilizing component 2005 thereby to stretch the elbow 1655 of the wearer when positioned thereon. Although illustrated occurring in three increments, this rotation and stretching of the wearer’s elbow 1655 may occur in 1, 2, 4, or more stages or increments, depending on the individual therapeutic regimen of the wearer. [00107] As illustrated in FIGS. 20a, 20b, and 20c, in an embodiment the ratcheting joint 130 may be used simultaneously or sequentially with the ratcheting joint 2030 so as to simultaneously or sequentially stretch the wrist 1650 and elbow 1655 of the wearer, respectively. In other embodiments, the ratcheting joint 130 of the forearm stabilizing component 105, and the ratcheting joint 2030 of the forearm stabilizing component may be used at separate times in the therapeutic process, as will be readily understood by one of ordinary skill in the art. [00108] In the embodiments 2000a-2000c illustrated in FIGS.20a-20c, a cone fingers and hand extension component 135 is illustrated being used in conjunction with the forearm stabilizing component 105 and upper arm stabilizing component 2005. In other embodiments, any combination of one or more of the cone, clam, and paddle fingers and hand extension components 135, 235, 335 may be used in conjunction with the forearm stabilizing component 105 and upper arm stabilizing component 2005 so as to simultaneously or sequentially stretch each of the wearer’s fingers and hand 1645, wrist 1650, and elbow 1655. [00109] According to an embodiment, a method for counteracting contracture in an upper extremity of a wearer may include attaching an upper arm stabilizing component 2005 to the forearm stabilizing component 105, and incrementally rotating a ratcheting joint 2030 positioned to extend from the upper arm stabilizing component 2005 to the forearm stabilizing component 105 so as to allow controlled incremental downward rotation of the forearm stabilizing component 105 into vertical alignment with the upper arm stabilizing component 2005 thereby to the stretch the elbow of the wearer when positioned thereon. [00110] In some stroke survivors, in addition to experiencing spasticity and contracture of their fingers, hands, wrists, elbows, and shoulders, pronation or supination (inward or outward rotation) of the wrist may also result. In the embodiment 2100 illustrated in FIGS.21-24, an upper extremity orthotic system having a wrist pronation and supination correction component 2165 is shown to address this condition. FIG.21 is a perspective view of an upper extremity orthotic system having a wrist pronation and supination correction component and a cone fingers and hand extension component. FIG. 22 is a left side view of an upper extremity orthotic system having a wrist pronation and supination correction component and a cone fingers and hand extension component. FIG. 23 is a right side view of an upper extremity orthotic system having a wrist pronation and supination correction component and a cone fingers and hand extension component. FIG.24 is a top view of an upper extremity orthotic system having a wrist pronation and supination correction component and a cone fingers and hand extension component. In the illustrated embodiment 2100, the wrist pronation and supination correction component 2165 may be connected to the elongate rigid member 110 of the forearm stabilizing component 105, and may include a ratcheting strap positioned to at least partially encircle the wearer’s wrist when positioned thereon. The ratcheting strap may be positioned to allow incremental rotation of the wearer’s wrist with respect to the forearm stabilizing component in a single direction, so as to facilitate correction of pronation or supination of the wearer’s wrist when positioned thereon. [00111] FIGS.25a-25c illustrate embodiments 2500a-2500c of an example process of correcting pronation of the wearer’s wrist 1650 using the wrist pronation and supination correction component 2065. FIG.25a is a perspective view of a wearer wearing an upper extremity orthotic system having a wrist pronation and supination correction component and a cone fingers and hand extension component, in which the wearer’s wrist is in a most pronated position. FIG. 25b is a perspective view of a wearer wearing an upper extremity orthotic system having a wrist pronation and supination correction component and a cone fingers and hand extension component, in which the wearer’s wrist is in a less pronated position. FIG.25c is a perspective view of a wearer wearing an upper extremity orthotic system having a wrist pronation and supination correction component and a cone fingers and hand extension component, in which the wearer’s wrist is in a least pronated position. As illustrated, the ratcheting strap of the pronation and supination correction component 2065 may be incrementally rotated around the wearer’s wrist 1650 so as to gradually rotate the wearer’s wrist 1650 with respect to the forearm stabilizing component 105 until the wearer’s wrist is properly aligned. In some embodiments, the ratcheting strap may be formed of a rigid or semi- rigid arcuate plastic or composite material, or any other suitable material as will be readily understood by one of ordinary skill in the art. The ratcheting strap may be positioned to rotate in a single direction or bidirectionally, according to various embodiments. [00112] In some embodiments, this rotation correction may occur simultaneously with the stretching achieved by one of more of the fingers and hand extension components 135, 235, 355, the ratcheting joint 130 of the forearm stabilizing component 105, and the ratcheting joint 2030 of the forearm stabilizing component. In other embodiments, this rotation correction may occur sequentially or as part of a separate therapeutic regimen from one or more of the fingers and hand extension components 135, 235, 355, the ratcheting joint 130 of the forearm stabilizing component 105, and the ratcheting joint 2030 of the forearm stabilizing component. As will be readily understood by one of ordinary skill in the art, the modular nature of the upper extremity orthotic system described herein allows for tailoring of therapeutic regimens to individual stroke survivors based on individual treatment timelines and physiological needs. Although illustrated in embodiments 2500a-2500c in use with a cone fingers and hand extension component 135, in various other embodiments the wrist pronation and supination correction component 2065 may be used in conjunction with any combination of the cone, clam, and paddle fingers and hand extension components 135, 235, 335. [00113] In an embodiment, a method of counteracting contracture in an upper extremity of a wearer may include connecting a wrist pronation and supination correction component 2065 to the elongate rigid member 110 of the forearm stabilizing component 105, and incrementally rotating the wrist pronation and supination correction component 2065 with respect to the forearm stabilizing component in a single direction, so as to facilitate correction of pronation or supination of the wearer’s wrist when positioned thereon. [00114] In an embodiment 2600 illustrated in FIG.26, the upper extremity orthotic system may further include a shoulder stabilizing component 2605, positioned so as to facilitate stretching of the wearer’s shoulder 1660 that has succumbed to spasticity and contracture as a result of a stroke or other hemorrhagic or ischemic event. The shoulder stabilizing component 2605 may include a shoulder securing member 2615 positioned to at least partially encircle a shoulder of the wearer opposite to the arm of the wearer on which the upper arm stabilizing component 2005 is positioned when positioned thereon. The shoulder securing member 2615 may serve to brace the shoulder stabilizing component 2605 against the unaffected shoulder, while facilitating outward rotation and stretching of the affected shoulder 1660. The shoulder stabilizing component 2605 also may include an elongate strap member 2610 positioned to stretchably connect the shoulder securing member 2615 to the upper arm stabilizing component 2005. The elongate strap member 2610 may have an adjustable length so as to allow the affected shoulder 1660 of the wearer to be incrementally rotated backward and stretched to counteract contracture when positioned thereon. [00115] In the illustrated embodiment 2600, the elongate strap member 2610 is a Velcro strap positioned to be tightened across the wearer’s back so as to facilitate backward rotation and stretching of the wearer’s shoulder as the strap is tightened. In other embodiments, the elongate strap member 2610 may be formed of any material suitable to facilitate incremental or gradual tightening of the strap so as to facilitate rotation and stretching of the wearer’s shoulder as the strap is tightened, for example a rigid or semi-rigid plastic or composite material, including a ratcheting component, or any other suitable material as will be readily understood by one of ordinary skill in the art. The positioning and configuration of the elongate strap member 2610 may allow the wearer to reach back with his unaffected arm and tighten the strap himself during treatment, without the need for caregiver assistance. In other embodiments the elongate strap member 2610 may be positioned such that a caregiver may be required to adjust the strap length and tightness. [00116] As illustrated in the embodiment 2600 of FIG.26, the shoulder stabilizing component 2605 may be used in conjunction with any of one or more fingers and hand extension components 135, 235, 335, the forearm stabilizing component 105, and the upper arm stabilizing component 2005. Although illustrated with the cone fingers and hand extension component 135, the clam and paddle fingers and hand extension components 235, 335 described herein also are contemplated. Like the ratcheting joints 130, 2030, the elongate strap member 2610 may be used simultaneously or sequentially with the other components of the upper extremity orthotic system so as to facilitate either simultaneous or sequential stretching of each of the wearer’s fingers and hand 1645, wrist 1650, elbow 1655, and shoulder 1660, according to the individual physiological needs and therapeutic regimen of the wearer. [00117] According to an embodiment, a method for counteracting contracture in an upper extremity of a wearer may include connecting a shoulder stabilizing component 2605 to the upper arm stabilizing component 2005, and incrementally tightening an elongate strap member 2610 so as to incrementally rotate the affected shoulder of the wearer backward so as to stretch the shoulder and counteract contracture when positioned thereon. [00118] The present disclosure also is directed to an upper extremity contracture counteracting orthotic kit 2700, for example as illustrated in FIG.27. In an embodiment, the kit 2700 may include a container 2770 positioned to contain components of an upper extremity contracture counteracting orthotic system. The container 2770 may include any appropriate box or vessel of varying materials, shapes, and sizes suitable to securely house and store the components of the upper extremity contracture counteracting orthotic system. For example, the container 2770 may be a plastic or composite box with an attached or detached lid, having molded indentations therein to receive and securely store each component of the upper extremity contracture counteracting orthotic system, though various other suitable container shapes and materials are contemplated, as will be readily understood by one of ordinary skill in the art. In the illustrated embodiment 2700, the container 2770 may include a forearm stabilizing component 105 and one or more fingers and hand extension components 135, 235, 335, selected from any combination of a cone fingers and hand extension component 135, a clam fingers and hand extension component 235, and a paddle fingers and hand extension component 335. In some embodiments, the container 2770 additionally may contain any combination of an upper arm stabilizing component 2005 and a shoulder stabilizing component 2605. In some embodiments, the forearm stabilizing component 105 included in the container 2770 may include a wrist pronation and supination correction component 2065.
