In addition, the position of the center of gravity (COG) has been reported as a critical factor for electromyographic activity of lower extremity muscles (Kvist and Gillquist, 2001; Nishiwaki et al., 2006), although active control of the posture was not examined in these reports.

An electromyographic examination found active denervation in the right C8-T1 and C7 innervated muscles (abductor pollicis brevis, first dorsal interosseus, abductor digiti minimi, extensor digitorum communis, flexor carpi radialis, and triceps muscles).
The root mean square (RMS) of the linear envelope in the time domain can be used to analyze when the rectified signal is passed through a filter to decrease high frequency fluctuations, allowing a clear evaluation of the electromyographic signal amplitude (14,17).
