Definitions
- This invention relates generally to training and rehabilitation of the upper extremities using inertial resistance.
- Most functional activities require coordinated movement of and function at multiple muscles and joints.
- An example of such an activity is the act of throwing a baseball, which requires coordinated use of, inter alia, the muscles serving the hand/wrist, elbow, shoulder, and scapular muscle-joint complexes.
- Each of these muscle-joint complexes includes major and minor mover muscles, which flex-extend, adduct-abduct, supinate-pronate, stabilize and rotate.
- These four muscle-joint complexes are collectively referred to as the upper extremity kinetic chain.
- Dumbbells are often used for training the upper extremities and typically consist of a handle connecting a pair of weighted discs.
- a dumbbell is typically balanced so that its center of gravity is located at the middle of its handle, so that an exerciser can grasp the handle with one hand and perform inertial-resistance exercises.
- Barbells are also primarily used for training the upper extremities. They typically consist of a relatively elongated cylindrical bar used as a handle that connects a pair of weighted discs, the bar most often being gripped by an exerciser with both hands while performing inertial-resistance exercises.
- the center of gravity of a barbell is normally positioned in the center of the bar between the weighted discs, which position allows an exerciser to balance the barbell in both hands while performing inertial-resistance exercises.
- Barbells are normally either made so that weighted discs can be slid on * and off the bar or with fixed weighted discs permanently attached. Dumbbells and barbells are collectively termed free weights.
- Exercise machines have been devised to train and/or rehabilitate the upper extremities.
- Exercise machines most often consist of an inertial resistance such as a weight, elastic member or flexible member, hydraulic piston, or the like, which is connected to a part of an exerciser's body by a handle, pad, stirrup, strap, or other means for transferring force applied by muscular effort by the exerciser via a cable, lever, or other connective means to the inertial resistance.
- an inertial resistance such as a weight, elastic member or flexible member, hydraulic piston, or the like
- One drawback to prior art free weights and exercise machines is their inability to exercise the stabilizer and rotator muscles of the upper extremity kinetic chain. This is due to the fact that free weights and machines involve two- dimensional exercise movement paths while stability and rotational strength stimuli require three
- an upper extremity exercise such as the barbell biceps curl is designated a dead hand exercise, because it stresses the elbow flexor muscles (i.e., the major movers for a barbell biceps curl) almost exclusively, and, at best, only minimally stimulates the stabilizer muscles of the upper extremity kinetic chain, including the hand/wrist, the limited isometric flexion/extension of the hand/wrist muscle-joint complex discussed above being the minimal stabilizer stimulus.
- the elbow flexor muscles i.e., the major movers for a barbell biceps curl
- dead hand refers to an essentially fixed isometrically contracted hand-wrist position which predominates during the use of a traditional barbell in particular, dumbbell use to a lesser degree, and most exercise machines.
- the isometric dead hand position is neutral between wrist flexion and extension, and wrist ulnar and radial deviation. Once the start position of a dead hand exercise is assumed, the hand-wrist remains isometrically fixed for the duration of the exercise.
- moment arm variations refers to the ability to change not only the amount of inertial resistance applied during the exercise, but also its point of application, so that the torque, linear resistance, and/or stabilizing resistance applied to the upper extremity kinetic chain can be varied and customized to train strength and flexibility across all movement potentials of all four muscle- joint complexes of the upper extremity kinetic chain.
- a prior art dumbbell can be used with a single slightly varying moment arm along the axis of the handle, which extends between the two weighted discs.
- an exerciser sometimes will grip the handle of the dumbbell with one side of their fist abutting against one of the weighted discs so that the center of gravity of the dumbbell is no longer in the center of the fist.
- the exerciser can slightly vary the moment arm in such a way as to increase the torque applied, for example, during either pronation or supination of the elbow muscle-joint complex.
- dumbbell fly exercise to the four- joint kinetic chain illustrates the delimited training effect of prior art training.
- the hand/wrist remains in a isometrically contracted position midway between flexion and extension and between radial and ulnar deviation once the dumbbell has been grasped.
- the forearm is pronated in an isometric contraction.
- the elbow is partially flexed while the shoulder performs lateral abduction.
- the exercise is essentially two-dimensional and there is little or no rotational or stability-strength stimulus and the exerciser is only performing the exercise in opposition to the pull of gravity.
- Prior art barbells and exercise machines are even more limited than dumbbells with respect to moment arm variations, both in the number and degree of moment arm variations that are possible and in their ability to train the rotator and stabilizer muscles of the upper extremity kinetic chain as a result of the variations.
- Exercise machines typically provide no moment arm variations during the course of an exercise.
- the number and degree of moment arm variations, if any, provided by an exercise machine would by necessity be fixed by the machine's structure, which would also eliminate stimulus of the stabilizer muscles, given that exercise machines do the stabilizing for the exerciser and thus allow the exerciser to work only the major movers at a single joint, as a result of the machines' fixed exercise movement paths.
- Another drawback associated with free weights and exercise machines is their inability to adequately correct an exerciser's limited range of motion in one or more of the four muscle-joint complexes of the upper extremity kinetic chain so that the exerciser can perform a given exercise to his or her full anatomic potential range of motion.
- the larger the stature of the exerciser the more the fixed design of an exercise machine delimits the' effective range of motion available to the exerciser.
- muscle spasm An exerciser's limited range of motion is often also due to the presence of chronically contracted groups of muscle fibers commonly referred to as muscle spasm.
- Muscle spasm inherently inhibits movement, by neuro-muscular reflex action, particularly movement toward the extremes of a given joint's range of motion.
- the spasmed muscle fibers are not under conscious control and, when called on to move a joint structure into an unfamiliar part of a given range of motion, trigger further contraction, by protective reflex, of adjacent muscle (s) in an effort to protect the muscle-joint complex from injury or further injury.
- the spasmed muscle tissue can be disrupted or torn more easily due to its lowered elasticity.
- muscle spasm causes decreased blood and lymphatic fluid flow to the spasmed tissue, and resultant slowed healing, as well as impaired performance due to pain and decreased range of motion.
- Prior art exercise machines limit range of motion due to their two-dimensional fixed movement paths, and are largely dimensionally fixed; as such, they do not optimally accommodate different-sized exercisers. They also provide little or no stability strength stimulus because the machine stabilizes the weight for the exerciser. Free weights are only marginally effective at resetting muscle tonus because they operate only against gravity and provide little or no rotational stimulus. As such, free weights provide only two-dimensional strength stimulus; therefore, primary rotators, such as the teres major and popliteus, can go into spasm, remain in such a state, and inhibit movement via protective inhibition.
- Virtually all real-world upper extremity movements involve the upper extremity kinetic chain performing one or more of ten movements: hand/wrist radial deviation; hand/wrist ulnar deviation; hand/wrist flexion; hand/wrist extension; forearm supination; forearm pronation; elbow flexion; elbow extension; scapular protraction; scapular retraction; or various combinations of these movements.
- These ten movements cannot be fully trained along the entire upper extremity kinetic chain using prior art free weights or machines because movements using such devices are dead-hand movements.
- the hand/wrist complex is used only for fist/finger flexion in an isometric contraction mode during the entire exercise, and in effect merely acts as a static link between the upper extremity and the free weight or exercise machine so that the load can be applied to the specific major mover (s) of the upper extremity targeted by the exercise .
- the statically and isometrically contracted (i.e., dead hand) hand/wrist position of most free weight and exercise machines means that the rotary capability of an exerciser will be undertrained by prior art free weight and machine exercises.
- the effect of incomplete hand/wrist training has a domino-like effect along the upper extremity kinetic chain.
- the hand/wrist is not rotary trained; therefore, the elbow is not rotary trained.
- Proprioception has been generally defined as an organism' s precise sense of where it is in space and where its body parts are in relation to one another.
- proprioception is the ability of an exerciser to know where his body is positioned throughout the exercise range of motion, which allows the muscle fibers specifically, and various muscles generally, to be coordinated and fire in the proper sequence in order to properly execute the desired movement throughout the entire exercise.
- a baseball pitcher has not been properly proprioceptively conditioned and, as a result, his shoulder muscle-joint complex's external rotator muscles are strong but other parts of his upper extremity kinetic chain, such as the stabilizer muscles, are weak and/or spasmed, he will be unable to optimally implement the precise motor pattern required to skillfully throw the baseball.
- This inability will result in a significant chance of injury due to abbreviated ranges of motion caused by spasmed muscle fiber that not only cannot contribute to developing force to throw the ball, but which also inhibits the remaining muscle fiber from developing force maximally and/or explosively.
- Imbalance in the stabilizer muscles invariably leads to diminished performance and an enhanced risk of injury.
- Premature firing of stabilizer/antagonist muscles to decelerate the upper extremity during an attempt to execute a high-speed full range of motion upper extremity kinetic chain movement will often occur.
- the stabilizer/antagonist muscles will tend to contract to inhibit the throwing movement before he has released the javelin.
- This premature antagonist/stabilizer muscle firing occurs as a protective mechanism (i.e., protective inhibition), in an effort to slow the thrower's arm so that the major movers do not overpower the weak/spasmed stabilizer muscles and damage them or the joints themselves.
- the javelin thrower could increase his throwing speed not just by training the internal shoulder rotator/stabilizer muscles that contract during a throw, but also by training the antagonist muscles that decelerate the arm, so that the deceleration does not occur prematurely in the motion in order to protect the upper extremity from injury.
- prior art free weights and machines do not permit such complex training.
- Such complex training is not possible using prior art devices and methods because of the limitations of prior art free weights and exercise machines, in that they: 1) require slow lifting speed to control momentum; 2) employ a single-joint-dominant focus; 3) elicit a two-dimensional muscle stimulus; and 4) permit only abbreviated ranges of motion due to either machine design and/or the need to control momentum as the exercise is performed.
- Full anatomic range of motion training of the stabilizer/rotator muscles, and release of muscle spasm are inter-related. Being free of muscle spasm (i.e., normal muscle tonus) allows an exerciser to train through a full anatomic range of motion by serving to minimize protective reflex inhibition, which is a natural result of the muscle spasm as the exerciser tries to protect himself from injury. Strength imbalances such as overwhelming the comparatively weak stabilizer/rotator muscles is another source of protective reflex inhibition. Once normal muscle tonus is reestablished, pain/premature protective reflex inhibition ceases and full anatomic range of motion exercise is possible. The exerciser can now proceed to use his proprioceptive awareness during full anatomic range of motion exercise to develop highly-efficient movement patterns and new performance potential while maintaining his musculature relatively spasm free.
- the cumulative trauma cycle is started when muscle strength imbalance leads to an initial injury to the muscle, which injury leads to muscle weakness and more muscle spasm. Once the muscle starts to become weaker because of the spasm, blood and lymphatic flow through the muscle are decreased. The cycle can become chronic, with further decreased blood and lymph flow to the muscles, increased spasm, and eventually scar tissue formation. Further impaired range of motion and consequent vulnerability of the muscle to more serious injury, including muscle tears, often result.
- Another drawback of prior art free weights and machine exercises is their inability to train the muscles of the upper extremity kinetic chain over a full range of motion to full anatomic potential.
- the ability to train the upper extremities over the full anatomic range of motion is therefore of critical significance as a training and rehabilitation goal, because such training allows an exerciser to attain conscious neuro-muscular control over the full anatomic range of motion for a given exercise, which enhanced range of motion results in both injury resistance and maximal performance expression. Injuries often occur due to insufficient range of motion when an upper extremity joint is taken into an unfamiliar part of range of motion by an external force such as a fall or blow; injury to soft tissue and/or joint structures often results.
- a device that is adapted to permit multiple moment arm variations during live-hand exercises of the upper extremity kinetic chain.

- live-hand upper extremity training and rehabilitation device 100 embodying concepts of the present invention.
- live-hand refers to a dynamic, four-dimensional (i.e., up-down/side- side/rotational) resistance application that varies continuously throughout the duration of an exercise.
- a live- hand device optimally stimulates all three pairs of possible anatomic movements of the hand-wrist-forearm complex (i.e., ulnar-radial deviation; flexion-extension; supination- pronation) by forcing the exerciser to engage his entire upper extremity kinetic chain during exercises performed with the device.
- the device includes a cross-sectionally substantially cylindrical annular base 102 having a distal end 104 and a proximal end 106, an opening 108 at the proximal end 106, a plurality of proximal notches 110 proximate the proximal end 106 and distal notches 110a proximate the distal end 104, and a longitudinal axis 112 running substantially perpendicularly to the ends 104 and 106 of the base 102.

- a deepest point 116 of each notch 110 or 110a is defined as the point on the notch 110 or 110a closest to the opposite end 104 or 106 of the base 102.
- the deepest point 116 of a proximal notch 110 is the closest point on the proximal notch 110 to the distal end 104 of the base
- the base 102 has an interior surface 118 and an opposing exterior surface 120.
- the exterior surface 120 of the base 102 is covered at least in part by a non-slip material (not shown) .
- the base 102 also preferably includes at least one indicator (not shown) to demarcate rotation of the device 100 in an exerciser's hand.

- Each of the knobs 128 is adapted to fit within one of the apertures 130 so that the handle 122 can be positioned along the longitudinal axis 112 of the base 102 and then locked into place using the knobs 128.
- any suitable means for adjusting the position of the handle 122 relative the base 102 in which the handle 122 can be securely held in place once it has been positionally adjusted can be employed, such as a screw-down type knob (not shown) , a removable cotter-pin (not shown) in each end 124 and 126 of the handle 122, or spacers (not shown) inserted above and below the knobs 124 and 126.
- At least one side hook 132 is attached to the base 102 proximate to the distal end 104 and/or the proximal end 106 of the base 102.
- the side hooks 132 can be used for a number of purposes, including retaining the flexible member 114 and creating a moment arm for application of force against the flexible member 114 when the flexible member 114 is in tension and also for helping to retain one or more detachable side weights (not shown) on the exterior surface 120 of the base 102.
- the side hooks 132 preferably have a minimal overhang distance ("D") from the base 102 in a plane perpendicular to the longitudinal axis
- any desired number of side hooks 132 can be attached to the distal end 104 and/or the proximal end 106 of the base 102.
- the side hooks 132 can be integral to the base 102 or can be separate pieces attached to the base 102.
- the side hooks 132 are centered on the deepest point 116 of the notches 110 or 110a.
- the device 100 also includes a nut 134 and a bolt 136 proximate the distal end 104 of the base 102, with the bolt 136 running substantially parallel to the longitudinal axis 112, the nut 134 and the bolt 136 being adapted to attach one or more end weights 138 to the distal end 104 of the base 102.
- a standard circular weight with a hole in its center is used as shown as the end weight 138 and is slid onto the bolt 136 and is then secured using the nut 134. More than one of the end weights 138 can be attached to the base 102 as needed.
- the nut 134 and the bolt 136 need not be used to secure one or more of the end weights 138 to the distal end 104 of the base 102, but rather, any suitable means for attaching at least one end weight 138 to the distal end 104 of the base 102 can be employed, such as clips (not shown) , brackets (not shown) , springs (not shown) , magnets (not shown) , specially-shaped weights that lock into the base (not shown), VELCRO (not shown), or the like.
- the distal end 104 of the base 102 can also be adapted to permanently retain one or more non-removable end weights (not shown) with or without the capability of adding additional end weights 138 to the distal end 104 of the base 102.

- resistance e.g., flexible member, detachable side weights, end weights, or any combination of the above
- mode e.g., rotational/torque stimulus, deviation of longitudinal axis of device from either line of pull of flexible member, line of pull of gravity, or both depending on selection from no. 1

- the present invention yields these variations by the following: 1) 5 variations in flexible member tracking on the exterior surface of the device; 2) variable flexible member attachment sites; 3) variable handle locations; 4) distal and/or proximal notch engagement of a flexible member; 5) detachable side weight belt placement; 6) end weights; 7) position of the device 0 vis-a-vis center of gravity of exerciser's body; and 8) position of anchor of second end of flexible member visa-vis center of gravity of exerciser's body.
- FIGURES 6-18 illustrate a number of 5 different upper extremity exercises that can be performed using a device embodying concepts of the present invention.
- the exercises described in connection with FIGURES 6- 17 depict an exerciser using a device as described herein
- the exercises described in FIGURES 6-18 can be performed using any 0 type of live-hand device, including but not limited to the device described herein, so long as the live-hand device is capable of providing comprehensive strength and flexibility stimulus of the four-joint upper extremity kinetic chain.
- the exercises described herein can be practiced apart ' 5 from use of the device described herein without departing the spirit and scope of Applicants' invention.
- any of the exercises 0 described herein can be performed with multiple variations of features of the device as described with respect to FIGS. 1-5, including but not limited to detachable side weights, end weights, varying handle positions, etc.
- a reference to the location of an inertial resistance herein is meant to refer to the direction of force applied to the device being used by the exerciser.
- an inertial resistance in the form of a weight stack might be physically located behind an exerciser, but its direction of force could be in front of the exerciser due to the use of cables, pulleys, and the like.
- many variations of the exercises described can be devised, as well as other ' exercises, without departing from the scope and spirit of the present invention.
- the process of resetting spasmed fiber includes selecting an upper extremity exercise that has its beginning point at the first end of the exerciser's substantially maximal range of motion and its end point at the second end of the exerciser' s substantially maximal range of motion. For example, if a shoulder rotation exercise were to be performed, the exerciser would perform the exercise from his substantially maximal internal rotation range of motion to his substantially maximal external rotation range of motion, or vice versa.
- the exerciser To reset spasmed muscle fiber or fibers to normal muscle tonus levels, the exerciser performs the upper extremity exercise using a live-hand exercise device adapted to stimulate at least one muscle fiber of one or more muscles of the exerciser's upper extremities.
- the exerciser substantially maximally voluntarily stretches the muscle fiber or fibers at the beginning point of the exercise (e.g., he internally rotates his shoulder as far as he can) , and then performs the exercise until he has substantially maximally voluntarily contracted the muscle fiber or fibers at the second point of the exercise
- the inventors have found that, in contrast to prior art exercise and rehabilitation methods that only exercise parts of the upper extremity kinetic chain, increased involvement of the entire upper extremity kinetic chain, and particularly the hand/wrist complex, as described herein is especially advantageous in resetting muscle spasm.
- the advantages of reset naturally follow, including increased blood and lymphatic flow, as well as improved proprioception, range of motion (i.e., flexibility), power, and speed expression and injury resistance.
- range of motion i.e., flexibility
- power i.e., and speed expression and injury resistance.
- maximum range of motion refers to an exerciser's abbreviated maximal flexibility in performing a particular exercise at the time he is performing the exercise due to muscle memory programming by daily usage.
- full anatomic range of motion refers to the exerciser's maximal flexibility possible given the structural limitations of the exerciser's skeletal/joint structure. Repeated use of the present invention will allow his maximal range of motion to approach full anatomic range of motion.
- FIGURES 6A-6D shown is an exerciser 600 in sequential phases of performing an internal shoulder rotation exercise.

- a second end of the flexible member 114 is attached to an inertial resistance, which is shown in Figures
- the device 100 preferably has been positioned at a first position at which the flexible member 114 is substantially taut and so that the flexible member 114 is wrapped around at least one-eighth of the exterior surface of the device 100 so that the line of pull of the flexible member 114 as the device is rotated in the exerciser's hand falls along the exterior surface of the device 100.
- the exerciser has grasped the handle of the device 100 with his palm facing substantially away from his torso and with his arm substantially extended at his side. It is preferable that the exerciser 600 marks the distance between the first position and the fixed point 602 following having positioned the device at the first position, so that when the flexible member 114 is elastic, the amount of resistance used during the exercise can be recorded.
- the exerciser 600 assumes an initial position as shown in FIG. 6A in which he has supinated his right forearm and externally rotated his right shoulder joint as far as he can.
- the exerciser preferably pauses and holds his arm in this substantially maximal range of motion position, which may or may not be his full anatomic range of motion.
- This step of supinating preferably also includes extending and radially deviating the wrist of the right arm, as shown in FIG. 6A. This hand/wrist involvement is indicative of the live-hand nature of the exercise, which maximally engages the entire upper extremity kinetic chain.
- the exerciser 600 is initially positioned so that his right hand is closer to the inertial resistance, shown as fixed point 602, than his left hand and the fixed point 602 is lateral to the exerciser
- the fixed point 602 is preferably at approximately the exerciser's 600 waist level.
- FIGURES 6B and 6C illustrate intermediate phases of the exercise between FIGS. 6A and 6D.

- the hand/wrist complex in particular is stimulated to a greater degree when the sum of the forces acting on the device 100 are such that the force is not applied through the center of the exerciser's 600 hand, but rather is applied at some other point of the device 100 so that a torque factor is induced.
- the torque factor requires the exerciser to engage his upper extremity musculature to a greater degree in order to perform the exercise than if he were using a dead hand device such as those of the prior art.
- a further torque stimulus can be provided by detachable side weights (not shown) and a wrist extension-flexion and radial ulnar deviation stimulus can be provided by end weights (not shown) .

- the exercise can be performed with the left arm in a manner that will be apparent to those skilled in the art. It is preferable that the exerciser 600 determine that the device 100 is positioned at the same position during the performance of the exercise with the left arm as it was positioned during performance of the exercise with the right arm, so that the same amount of resistance is applied to each arm during performance of the exercise.
- the position of the device 100 is most critical when an elastic flexible member 114 is used, since the resistance of an elastic flexible member 114 is dependent upon the amount it is stretched.
- positioning of the device 100 when an inelastic flexible member 114 is used is not nearly as critical, since resistance applied through the inelastic flexible member 114 does not vary with distance.
