Definitions
- the present invention relates to the fields of rehabilitation, Physical Therapy, exercise, and fitness. More specifically, the invention relates to apparatuses that facilitate motion and exercise.
- Joints and muscles are very important for various physical activities such as safe ambulation (walking), stair climbing, moving objects, for balancing, and all other daily mobility activities.
- Most joints are capable of a wide range of motion including extension and flexion allowing for motions which may move a structure away from or towards the center of the body.
- Flexion describes a bending movement that decreases the angle between two body parts.
- flexion refers to movement in the anterior direction.
- bending the elbow, or clenching a hand into a fist are examples of flexion.
- Flexion of the shoulder or hip refers to movement of the arm or leg forward.
- Extension is the opposite of flexion, describing a straightening movement that increases the angle between body parts.
- extension refers to movement in the posterior direction. For example, when standing up, the knees are extended. Extension of the hip or shoulder moves the arm or leg backward. When the chin is against the chest, the head is flexed, and the trunk is flexed when a person leans forward.
- a physical therapist may encourage a patient to perform heel slide exercises and range of motion by placing their foot on a towel allowing flexion and extension exercises to be performed by sliding their foot or heel back and forth over a hard surface.
- a physical therapist may encourage a patient to perform heel slides by placing their foot on a wooden board allowing flexion and extension exercises to be performed by sliding their foot and or heel back and forth over a soft or carpeted surface.
- a towel slides poorly over a soft or carpeted surface and a wooden board slides poorly over hard surfaces and may damage a hard surface over which it is slid.
- Even wooden or plastic boards comprising low friction skid plates may damage hard surfaces with a repetitive sliding motion which does not promote exercise compliance and consistency and does not motivate the patient to complete their heel slide exercise.
- a Physical Therapist may encourage a patient to perform heel slide exercises by lying, sitting or long sitting on a mat or bed and sliding the foot or heel back and forth in flexion and extension on the mat or bed, however, the foot slides poorly over the (lumpy) bed surface and it is difficult to slide the foot back and forth on a mat due to friction.
- a sliding exercise apparatus which may be configured to assist a person with physical activities. These physical activities may be used for rehabilitation and exercise purposes include, but are not limited to, neural muscular reeducation, proprioceptive rehabilitation, and rehabilitation for the hip, ankle, shoulder, elbow, and any other muscle and joint which may benefit from being supported by the sliding exercise apparatus during motion.
- the apparatus may include a hard layer frame which may comprise a hard surface; a body contacting layer which may comprise a body contacting surface located opposite to said hard surface and which may be coupled to the hard layer frame opposite to the hard surface; and a removable cover which may be configured to cover a portion of the hard surface.
- the hard surface may be configured to make contact with the ground such as when the removable cover is removed from covering the hard surface, and the removable cover may be configured to make contact with the ground when the removable cover is positioned over a portion of the hard surface.
- the hard layer frame may comprise a beveled edge that extends around and protrudes away from the perimeter of the hard surface, and the beveled edge may curve away from the hard surface towards the body contacting surface.
- the removable cover may further comprise a resilient perimeter, and the resilient perimeter may be stretched over the hard surface and the beveled edge to removably couple the removable cover to the hard layer frame.
- a method of providing flexion and extension exercise to a joint may include: removing the torso weight from acting on appendage of a user; positioning a sliding exercise apparatus on a resistive surface; positioning an appendage of the user on a body contacting surface of sliding exercise apparatus; moving an appendage joint in flexion motion under a level of frictional resistance by moving appendage on apparatus towards torso; and moving appendage joint in extension motion under the level of frictional resistance by moving appendage on apparatus away from torso.
- a method of providing flexion and extension exercise under different levels of frictional resistance to a joint may include: removing the torso weight from acting on appendage of a user; positioning a sliding exercise apparatus on a resistive surface so that hard surface is in contact with resistive surface to provide first level of frictional resistance; positioning a sliding exercise apparatus on a resistive surface so that removable cover surface is in contact with resistive surface to provide second level of frictional resistance; positioning an appendage of the user on the sliding exercise apparatus; moving an appendage joint in flexion motion under a selected level of frictional resistance by moving appendage on apparatus towards torso; and moving appendage joint in extension motion under the selected level of frictional resistance by moving appendage on apparatus away from torso.

Description
- This application is a continuation-in-part of U.S. Non-Provisional application Ser. No. 14/808,582, filed on Jul. 24, 2015, entitled “SLIDING EXERCISE APPARATUS”, which claims the benefit of U.S. Non-Provisional application Ser. No. 14/524,389, filed on Oct. 27, 2014, entitled “SLIDING EXERCISE APPARATUS”, the entire disclosures of which are incorporated by reference herein.
- The present invention relates to the fields of rehabilitation, Physical Therapy, exercise, and fitness. More specifically, the invention relates to apparatuses that facilitate motion and exercise.
- Joints and muscles are very important for various physical activities such as safe ambulation (walking), stair climbing, moving objects, for balancing, and all other daily mobility activities. Most joints are capable of a wide range of motion including extension and flexion allowing for motions which may move a structure away from or towards the center of the body. Flexion describes a bending movement that decreases the angle between two body parts. When a joint can move forward and backward, such as the neck and trunk, flexion refers to movement in the anterior direction. For example, bending the elbow, or clenching a hand into a fist, are examples of flexion. When sitting down, the knees are flexed. Flexion of the shoulder or hip refers to movement of the arm or leg forward. Extension is the opposite of flexion, describing a straightening movement that increases the angle between body parts. When a joint can move forward and backward, such as the neck and trunk, extension refers to movement in the posterior direction. For example, when standing up, the knees are extended. Extension of the hip or shoulder moves the arm or leg backward. When the chin is against the chest, the head is flexed, and the trunk is flexed when a person leans forward.
- When injury occurs such as after stress, overuse, joint replacement or surgery, it is desirable to rehabilitate and exercise the affected muscles and joints to restore their ability to perform physical activities. In order to restore stability and range of movement, increase strength, and recover neurological capacities allowing the previously injured person the health and quality of life benefits afforded by the ability to perform physical activities. To aid in recovery, a person is often required to perform flexion and extension as well as other range of motion exercises with the injured or replaced joint.
- Unfortunately, current flexion and extension exercise apparatuses are typically bulky and expensive which is prohibitive for in home, hospital and or clinic use which limits the time and frequency a person is able to perform these beneficial exercises. Additionally, current flexion and extension exercise apparatuses are also unable to allow a person to perform the exercises on different surfaces such as when a patient is required to perform heel slide flexion and extension exercises.
- For example, a physical therapist may encourage a patient to perform heel slide exercises and range of motion by placing their foot on a towel allowing flexion and extension exercises to be performed by sliding their foot or heel back and forth over a hard surface. In another example, a physical therapist may encourage a patient to perform heel slides by placing their foot on a wooden board allowing flexion and extension exercises to be performed by sliding their foot and or heel back and forth over a soft or carpeted surface. However, a towel slides poorly over a soft or carpeted surface and a wooden board slides poorly over hard surfaces and may damage a hard surface over which it is slid. Even wooden or plastic boards comprising low friction skid plates may damage hard surfaces with a repetitive sliding motion which does not promote exercise compliance and consistency and does not motivate the patient to complete their heel slide exercise. In another example, a Physical Therapist may encourage a patient to perform heel slide exercises by lying, sitting or long sitting on a mat or bed and sliding the foot or heel back and forth in flexion and extension on the mat or bed, however, the foot slides poorly over the (lumpy) bed surface and it is difficult to slide the foot back and forth on a mat due to friction.
- Therefore, a need exists for novel apparatuses that facilitate motion and exercise. There is a further need for novel apparatuses that facilitate flexion and extension motion that are not bulky or prohibitively expensive. Finally, there exists a need for novel apparatuses that facilitate flexion and extension motion and exercise over a variety of surfaces.
- A sliding exercise apparatus which may be configured to assist a person with physical activities is provided. These physical activities may be used for rehabilitation and exercise purposes include, but are not limited to, neural muscular reeducation, proprioceptive rehabilitation, and rehabilitation for the hip, ankle, shoulder, elbow, and any other muscle and joint which may benefit from being supported by the sliding exercise apparatus during motion. In some embodiments, the apparatus may include a hard layer frame which may comprise a hard surface; a body contacting layer which may comprise a body contacting surface located opposite to said hard surface and which may be coupled to the hard layer frame opposite to the hard surface; and a removable cover which may be configured to cover a portion of the hard surface. The hard surface may be configured to make contact with the ground such as when the removable cover is removed from covering the hard surface, and the removable cover may be configured to make contact with the ground when the removable cover is positioned over a portion of the hard surface.
- In further preferred embodiments, the hard layer frame may comprise a beveled edge that extends around and protrudes away from the perimeter of the hard surface, and the beveled edge may curve away from the hard surface towards the body contacting surface.
- In further preferred embodiments, the removable cover may further comprise a resilient perimeter, and the resilient perimeter may be stretched over the hard surface and the beveled edge to removably couple the removable cover to the hard layer frame.
- According to another aspect, a method of providing flexion and extension exercise to a joint is provided. In some embodiments, the method may include: removing the torso weight from acting on appendage of a user; positioning a sliding exercise apparatus on a resistive surface; positioning an appendage of the user on a body contacting surface of sliding exercise apparatus; moving an appendage joint in flexion motion under a level of frictional resistance by moving appendage on apparatus towards torso; and moving appendage joint in extension motion under the level of frictional resistance by moving appendage on apparatus away from torso.
- According to yet another aspect, a method of providing flexion and extension exercise under different levels of frictional resistance to a joint is provided. In some embodiments, the method may include: removing the torso weight from acting on appendage of a user; positioning a sliding exercise apparatus on a resistive surface so that hard surface is in contact with resistive surface to provide first level of frictional resistance; positioning a sliding exercise apparatus on a resistive surface so that removable cover surface is in contact with resistive surface to provide second level of frictional resistance; positioning an appendage of the user on the sliding exercise apparatus; moving an appendage joint in flexion motion under a selected level of frictional resistance by moving appendage on apparatus towards torso; and moving appendage joint in extension motion under the selected level of frictional resistance by moving appendage on apparatus away from torso.

FIGS. 8-10 , aremovable cover 20 may be removably coupled to or over portions of thehard layer frame 11 and/or to or over portions of abody contacting surface 23. In some embodiments, aremovable cover 20 may cover one or more portions of the hard surface 14 (FIGS. 3-5, 10 ). Theremovable cover 20 may comprise a removable cover surface 25 (FIG. 10 ) which may be configured to contact and move across a resistive surface 300 (FIGS. 11 and 12 ) which may include a floor surface, such as carpeting, tile, linoleum, wood, a bed surface, such as a quilt, blanket, sheet, a furniture surface, such as a cushion, throw cover, or any other surface and the like.

In still other embodiments, aresilient perimeter 21 may comprise a draw string, or the like, which may be tightened and loosened in order to secure and remove theremovable cover 20 from covering portions of thehard layer frame 11. - Referring now to
FIG. 11 , a perspective view of an alternative example of a slidingexercise apparatus 100 in use by auser 200 without the removable cover 20 (FIGS. 8, 9, 10, and 12 ) on aresistive surface 300 according to various embodiments described herein is illustrated. In this example, theuser 200 has placed their foot onto thebody contacting surface 23 of thebody contacting layer 22 of theapparatus 100, while the hard surface 14 (FIGS. 3-5, 10 ) of thehard layer frame 11 may contact a surface such as a floor. By moving their foot while it is resting on thebody contacting layer 22 of theapparatus 100, thehard layer frame 11 may slide across aresistive surface 300, such as a floor surface or bed surface, to allow theuser 200 to perform movements such as flexion and extension movements by decreasing the frictional resistance between theapparatus 100 and softerresistive surfaces 300, such as floor coverings including carpets, rugs, and the like, be surfaces including blankets, sheets, quilts, and the like. - Alternatively, as shown in
FIG. 12 , a perspective view of an alternative example of a slidingexercise apparatus 100 in use by auser 200 with theremovable cover 20 positioned over portions of the hard layer frame on aresistive surface 300 according to various embodiments described herein. In this example, theuser 200 has placed their foot onto thebody contacting surface 23 of thebody contacting layer 22 of theapparatus 100, while theremovable cover 20 may contact aresistive surface 300 such as a floor instead of the hard surface 14 (FIGS. 3-5, 10 ) of the hard layer frame 11 (FIGS. 1-8, 10, and 11 ). By moving their foot while it is resting on thebody contacting layer 22 of theapparatus 100, theremovable cover 20 may slide acrossresistive surfaces 300 to allow theuser 200 to perform movements such as flexion and extension movements by decreasing the frictional resistance between theapparatus 100 and harderresistive surfaces 300 and floor coverings such as tiling, hard wood, linoleum, and the like. -
FIG. 13 depicts a block diagram of an example of a method of providing flexion and extension exercise to a joint (“the method”) 400 according to various embodiments described herein. Themethod 400 may be accomplished with a sliding exercise apparatus 100 (FIGS. 1-12 ) by a user 200 (FIGS. 1, 7, 11, and 12 ) having a torso and a joint that is in communication with an appendage and the torso. For example, the joint may be the knee joint and the appendage may be the foot, optionally disposed within an article of footwear such as a shoe or sock. - In some embodiments, the
method 400 may begin 401 and the torso weight may be removed from acting on the appendage of theuser 200 in step 402. In further embodiments, the torso weight may be removed from acting on the appendage of theuser 200 by having theuser 200 occupy a seated position so that the weight of their torso is supported by a chair, article of furniture or the like. In other embodiments, the torso weight may be removed from acting on the appendage of theuser 200 by having theuser 200 occupy a supine position so that the weight of their torso is supported by a bed, resistive surface 300 (FIGS. 11 and 12 ), article of furniture, or the like thereby allowing theuser 200 to recline their torso or lay down their torso. - Next in
step 403, the slidingexercise apparatus 100 may be positioned on aresistive surface 300 which may include a floor surface, such as carpeting, tile, linoleum, wood, a bed surface, such as a quilt, blanket, sheet, a furniture surface, such as a cushion, throw cover, or any other surface and the like. In some embodiments, theapparatus 100 may be positioned so that thehard surface 14 is in contact with theresistive surface 300 as shown inFIG. 11 . In other embodiments, theapparatus 100 may be positioned so that theremovable cover surface 25 is in contact with theresistive surface 300 as shown inFIG. 12 . - In
step 404, the appendage may be positioned on thebody contacting surface 23 of slidingexercise apparatus 100. For example, the foot, calf, knee, hand, arm, neck, and the like may be placed or positioned on thebody contacting surface 23 so that the appendage is resting on theapparatus 100 and so that theapparatus 100 provides the interface between the appendage and theresistive surface 300. - Next, the appendage joint may be moved in flexion motion under a level of frictional resistance by moving appendage on the
apparatus 100 towards the torso while the appendage is in contact with theapparatus 100 and while theapparatus 100 is also in contact with theresistive surface 300 instep 405. In this manner, as theapparatus 100 moves across theresistive surface 300, the friction between theapparatus 100 and theresistive surface 300 may provide the frictional resistance to the flexion motion. This frictional resistance, in addition to supporting the appendage during flexion motion, facilitates motion and exercise of the joint, muscles associated with the joint, and/or other muscles and joints of the user. - In step 406, the appendage joint may be moved in extension motion under a level of frictional resistance by moving appendage on the
apparatus 100 away from the torso while the appendage is in contact with theapparatus 100 and while theapparatus 100 is also in contact with theresistive surface 300. In this manner, as theapparatus 100 moves across theresistive surface 300, the friction between theapparatus 100 and theresistive surface 300 may provide the frictional resistance to the extension motion. This frictional resistance, in addition to supporting the appendage during extension motion, facilitates motion and exercise of the joint, muscles associated with the joint, and/or other muscles and joints of the user. - Optionally, steps 405 and/or 406 may be repeated for any desired number of times or repetitions. Once the desired number of repetitions, including no repetitions, of
steps 405 and 406 has been accomplished, themethod 400 may finish 407. -
FIG. 14 illustrates a block diagram of an example of a method of providing flexion and extension exercise under different levels of frictional resistance to a joint (“the method”) 500 according to various embodiments described herein. The method 500 may be accomplished with a sliding exercise apparatus 100 (FIGS. 1-12 ) by a user 200 (FIGS. 1, 7, 11, and 12 ) having a torso and a joint that is in communication with an appendage and the torso. For example, the joint may be the shoulder joint and the appendage may be the arm or elbow. - In some embodiments, the method 500 may begin 501 and the torso weight may be removed from acting on the appendage of the
user 200 in step 502. In further embodiments, the torso weight may be removed from acting on the appendage of theuser 200 by having theuser 200 occupy a seated position so that the weight of their torso is supported by a chair, article of furniture or the like. In other embodiments, the torso weight may be removed from acting on the appendage of theuser 200 by having theuser 200 occupy a supine position so that the weight of their torso is supported by a bed, resistive surface 300 (FIGS. 11 and 12 ), article of furniture, or the like thereby allowing theuser 200 to recline their torso or lay down their torso. - In
step 503, the slidingexercise apparatus 100 may be positioned on aresistive surface 300 which may include a floor surface, such as carpeting, tile, linoleum, wood, a bed surface, such as a quilt, blanket, sheet, a furniture surface, such as a cushion, throw cover, or any other surface and the like, so that thehard surface 14 is in contact withresistive surface 300 to provide first level of frictional resistance as shown inFIG. 11 . Since thehard surface 14 preferably may be made of a smooth, hard material, it will have a first level of frictional resistance as it moves across theresistive surface 300 whether theresistive surface 300 is a soft surface, such as carpeting, or a hard surface, such as hardwood flooring. - In step 504, the sliding
exercise apparatus 100 may be positioned on aresistive surface 300 which may include a floor surface, such as carpeting, tile, linoleum, wood, a bed surface, such as a quilt, blanket, sheet, a furniture surface, such as a cushion, throw cover, or any other surface and the like, so that removable cover surface 25 (FIG. 10 ) is in contact withresistive surface 300 to provide second level of frictional resistance as shown inFIG. 12 . Since theremovable cover surface 25 preferably may be made of a cloth or fabric material, it will have a second level of frictional resistance that is different than the first level of frictional resistance provided by thehard surface 14 as it moves across theresistive surface 300 whether theresistive surface 300 is a soft surface, such as carpeting, or a hard surface, such as hardwood flooring. - Next in step 505, the appendage may be positioned on the
body contacting surface 23 of slidingexercise apparatus 100. For example, the foot, calf, knee, hand, arm, neck, and the like may be placed or positioned on theapparatus 100 so that the appendage is resting on theapparatus 100 and so that theapparatus 100 provides the interface between the appendage and theresistive surface 300. - Next, the appendage joint may be moved in flexion motion under a selected level of frictional resistance by moving appendage on the
apparatus 100 towards the torso while the appendage is in contact with theapparatus 100 and while theapparatus 100 is also in contact with theresistive surface 300 instep 506. In this manner, as theapparatus 100 moves across theresistive surface 300, the friction between theapparatus 100 and theresistive surface 300 may provide the first level of frictional resistance, if thehard surface 14 is in contact withresistive surface 300, or may provide the second level of frictional resistance, if theremovable cover surface 25 is in contact withresistive surface 300, to the flexion motion. The selected frictional resistance level, in addition to supporting the appendage during flexion motion, facilitates motion and exercise of the joint, muscles associated with the joint, and/or other muscles and joints of the user. - In
step 507, the appendage joint may be moved in extension motion under a level of frictional resistance by moving appendage on theapparatus 100 away from the torso while the appendage is in contact with theapparatus 100 and while theapparatus 100 is also in contact with theresistive surface 300. In this manner, as theapparatus 100 moves across theresistive surface 300, the friction between theapparatus 100 and theresistive surface 300 may provide the first level of frictional resistance, if thehard surface 14 is in contact withresistive surface 300, or may provide the second level of frictional resistance, if theremovable cover surface 25 is in contact withresistive surface 300, to the extension motion. The selected frictional resistance level, in addition to supporting the appendage during extension motion, facilitates motion and exercise of the joint, muscles associated with the joint, and/or other muscles and joints of the user. - Optionally, steps 506 and/or 507 may be repeated for any desired number of times or repetitions. Once the desired number of repetitions, including no repetitions, of
steps - Although the present invention has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the present invention, are contemplated thereby, and are intended to be covered by the following claims.
