Abstract
Abstract A method is disclosed for detecting the intentional disabling of muscles which includes the steps of measuring the neuromuscular activation in a disabled muscle and comparing the neuromuscular activation of the muscle with that of a control muscle when performing a specified work task. To perform this comparison, an integrated electromyogram (emg) of a muscle which is synergist to the disabled muscle is compared with the integrated emg of a synergist control muscle wherein the control muscle corresponds to the disabled muscle but is on the opposite side of the human body or is the same muscle in a control population. Where only one muscle of a given type exists, the integrated emg thereof is compared with the norm of a matched population when performing the work task.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
118 words
A method of detecting the intentional disabling of a muscle comprising the steps of: measuring the neuromuscular activation of a muscle which is an antagonist to said disabled muscle when preforming a predetermined work task, and when at rest, measuring the neuromuscular activation of a control muscle which corresponds to said antagonist muscle when performing said work task, measuring the neuromuscular activation of a control muscle which corresponds to said disabled muscle when performing said work task, comparing the neuromuscular activity of said antagonist muscles to thereby derive the difference in neuromuscular activity therebetween, and comparing said difference in neuromuscular activation of said antagonist muscles to said measured activation of said control muscle corresponding to said disabled muscle.
Claim 2
Independent Claim
118 words
A method of detecting the intentional disabling of a muscle comprising the steps of: measuring the neuromuscular activation of a muscle which is an antagonist to said disabled muscle when preforming a predetermined work task, and when at rest, measuring the neuromuscular activation of a control muscle which corresponds to said antagonist muscle when performing said work task, measuring the neuromuscular activation of a control muscle which corresponds to said disabled muscle when performing said work task, comparing the neuromuscular activity of said antagonist muscles to thereby derive the difference in neuromuscular activity therebetween, and comparing said difference in neuromuscular activation of said antagonist muscles to said measured activation of said control muscle corresponding to said disabled muscle.
Claim 3
Dependent Claim
130 words
The method of claim 1 further comprising the steps of measuring the neuromuscular activation of a muscle which is an antagonist to said disabled muscle by measuring the integrated electromyogram thereof when said antagonist muscle performs said predetermined work task, measuring the neuromuscular activation of a control muscle corresponding to said antagonist muscle by measuring the integrated electromyogram thereof when performing said work task, measuring the neuromuscular activation of a control muscle corresponding to said disabled muscle by measuring the integrated electromyogram thereof when performing said work task, comparing the integrated electromyograms of said antagonist muscles to thereby derive the difference in neuromuscular activation of said muscles, comparing said difference in neuromuscular activation of said antagonist muscles to the integrated electromyogram of said control muscle corresponding to said disabled muscle.
Claim 4
Dependent Claim
94 words
The method of claim 2 further comprising the step of measuring the neuromuscular activation of said antagonist muscle by measuring the integrated electromyogram thereof when at rest, and solving the following equation: ID.sub.A = 100(A.sub.D -(A.sub.C +A.sub.D R))/P.sub.C where A D is the integrated electromyogram of said antagonist muscle, A D R is the integrated electromyogram of said antagonist muscle when at rest, A C is the integrated electromyogram of said control muscle corresponding to said antagonist muscle and P C is the integrated electromyogram of said control muscle corresponding to said disabled muscle.
Claim 5
Dependent Claim
88 words
The method of claim 1 further comprising the steps of comparing the neuromuscular activation of said control muscle which corresponds to said antagonist muscle with said antagonist muscle when said disabled muscle is at rest, wherein said comparing said difference in neuromuscular activation of said antagonist muscle to said measured activation of said control muscle includes the step of comparing the difference in neuromuscular activation of said control muscle and said antagonist muscle when said disabled muscle is at rest with said measured activation of said control muscle.
Claim 6
Independent Claim
90 words
A method of detecting the intentional disabling of a muscle comprising the steps of: measuring the neuromuscular activation of a muscle which is synergist to said disabled muscle by recording the integrated electromyogram of said muscle when performing a predetermined work task, measuring the neuromuscular activation of a control muscle corresponding to said synergist muscle when performing said work task by recording the integrated electromyogram of said muscle when performing said work task, and comparing said integrated electromyograms of said synergist muscles to derive the relative activation of each muscle.
Claim 7
Independent Claim
90 words
A method of detecting the intentional disabling of a muscle comprising the steps of: measuring the neuromuscular activation of a muscle which is synergist to said disabled muscle by recording the integrated electromyogram of said muscle when performing a predetermined work task, measuring the neuromuscular activation of a control muscle corresponding to said synergist muscle when performing said work task by recording the integrated electromyogram of said muscle when performing said work task, and comparing said integrated electromyograms of said synergist muscles to derive the relative activation of each muscle.
Claim 8
Independent Claim
141 words
A method of detecting the intentional disabling of a muscle comprising the steps of: measuring the neuromuscular activation of a muscle which is synergist to said disabled muscle by recording the integrated electromyogram of said muscle when performing a predetermined work task, measuring the neuromuscular activation of a control muscle corresponding to said synergist muscle when performing said work task by recording the integrated electromyogram of said muscle when performing said work task, and comparing said integrated electromyograms of said synergist muscles to derive the relative activation of each muscle by solving the following equations: ID.sub.S = 100 - 100S.sub.D /S.sub.C where S D is the integrated electromyogram of a muscle which is synergist to said disabled muscle and S C is the integrated electromyogram of said control muscle, and ID S is the quantized intentional disability of said disabled muscle.
Claim 9
Independent Claim
141 words
A method of detecting the intentional disabling of a muscle comprising the steps of: measuring the neuromuscular activation of a muscle which is synergist to said disabled muscle by recording the integrated electromyogram of said muscle when performing a predetermined work task, measuring the neuromuscular activation of a control muscle corresponding to said synergist muscle when performing said work task by recording the integrated electromyogram of said muscle when performing said work task, and comparing said integrated electromyograms of said synergist muscles to derive the relative activation of each muscle by solving the following equations: ID.sub.S = 100 - 100S.sub.D /S.sub.C where S D is the integrated electromyogram of a muscle which is synergist to said disabled muscle and S C is the integrated electromyogram of said control muscle, and ID S is the quantized intentional disability of said disabled muscle.
