Evaluation of motor control following thenar muscle fatigue using symmetrical index

Muscle weakness and fatigue are two factors that cause muscle injuries. The roll of motor control is important in regulation and reduction of this effect. Repetition of motion after muscle fatigue is due to the significant role of motor control system. The aim of this study was to evaluate the quality of roll control of central nervous system following fatigue in order to answer primary questions in therapeutic exercises. Twenty voluntary healthy subjects participated in this study. Dominant abductor policis brevis after surface electromyography (SEMG) of maximal voluntary contraction (MVC) fatigued by maximum three minutes isometric contraction in specific hand splint monitored by dynamometer until reduction of
