Abstract
Abstract A muscle function analysis system including a base; a restraint device supported by the base and shaped and arranged to receive and immobilize a human body portion retaining a muscle group concurrently activatable to produce a body function; and a support apparatus supported by the base and shaped and arranged to support other portions of the body, the support apparatus adapted to substantially isolate activity in the muscle group from muscle activity in the other body portions. Also included are an electrode array adapted for coupling to the muscle group so as to receive myoelectric signals generated by muscle activity therein and a processing system coupled to the electrode array and adapted to process the myoelectric signals. By isolating muscle activity in a particular muscle group, more useful data is obtained for evaluating muscle dysfunction in the group.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
132 words
A muscle function analysis system comprising: base means; restraint means supported by said base means and shaped and arranged to receive and immobilize one portion of a human body, said one portion retaining a muscle group concurrently activatable to produce a body function and said restraint means comprising mold means shaped to conform to said one portion; support means supported by said base means and shaped and arranged to support other portions of the body, said support means adapted to substantially isolate activity in said muscle group from muscle activity in said other portions of the body; electrode means adapted for coupling to said muscle group so as to receive myoelectric signals generated by muscle activity therein; and processing means coupled to said electrode means and adapted to process said myoelectric signals.
Claim 2
Dependent Claim
132 words
A muscle function analysis system comprising: base means; restraint means supported by said base means and shaped and arranged to receive and immobilize one portion of a human body, said one portion retaining a muscle group concurrently activatable to produce a body function and said restraint means comprising mold means shaped to conform to said one portion; support means supported by said base means and shaped and arranged to support other portions of the body, said support means adapted to substantially isolate activity in said muscle group from muscle activity in said other portions of the body; electrode means adapted for coupling to said muscle group so as to receive myoelectric signals generated by muscle activity therein; and processing means coupled to said electrode means and adapted to process said myoelectric signals.
Claim 3
Dependent Claim
43 words

Claim 11
Dependent Claim
32 words
A muscle function analysis system according to claim 4 including force constraint means supported by said base means and adapted to engage and prevent movement of the body's torso during extension thereof.
Claim 12
Dependent Claim
23 words
A muscle function analysis system according to claim 10 wherein said constraint means comprises a flexible strap adapted to engage the body's back.
Claim 13
Dependent Claim
24 words

Claim 14
Dependent Claim
27 words
A muscle function analysis system according to claim 12 wherein said support means comprises knee support means for supporting knees and foot support means for supporting feet.
Claim 15
Dependent Claim
39 words
A muscle function analysis system according to claim 13 wherein said knee support means is adapted to maintain the body's knee joints in flexion, and said foot support means is adapted to maintain the body's ankle joints in plantarflexion.
Claim 16
Dependent Claim
29 words
A muscle function analysis system according to claim 6 wherein said base means comprises a substantially vertical standard portion and a pedestal portion adapted to support the body's feet.
Claim 17
Dependent Claim
63 words
A muscle function analysis system according to claim 15 wherein said restraint means comprises a first coupling providing a given spacing between said standard portion and an upper portion of said mold means and a second coupling providing a predetermined spacing between said standard portion and a lower portion of said mold means, and said given spacing is greater than said predetermined spacing.
Claim 18
Dependent Claim
27 words
A muscle function analysis system according to claim 16 wherein said restraint means comprises adjustment means for selectively adjusting said predetermined spacing relative to said given spacing.
Claim 19
Dependent Claim
