Method of assessing intentional muscular disability
First Claim
1. 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, andcomparing said difference in neuromuscular activation of said antagonist muscles to said measured activation of said control muscle corresponding to said disabled muscle.

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.
The intentional disabling of muscles can also be detected by measuring the neuromuscular activation of a muscle which is antagonist to a disabled muscle and comparing this neuromuscular activation with that of a control muscle wherein the control muscle corresponds to the antagonist of the disabled muscle but is on the opposite side of the human body or is the same muscle in a control population.

5. 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.

6. 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;
space="preserve" listing-type="equation">ID.sub.S = 100 - 100S.sub.D /S.sub.Cwhere SD is the integrated electromyogram of a muscle which is synergist to said disabled muscle and SC is the integrated electromyogram of said control muscle, and IDS is the quantized intentional disability of said disabled muscle.
