ABSTRACT
This article presents an evaluation method of muscular atrophy caused by lack of use, employing surface electromyography.Describes a new instrument to measure muscular activity in a practical an reliabe way.For the performance of 96 tests, four muscles were select: wrist flexors, biceps rectus femoris, and the gastrocnemius.These were implemented in two groups: (1) comtrol group and (2) experimental group.The results obtained in all muscular groups measurered showed that the reason reference/affected in group (2) presented a variation of 27 percentage to 142 percentage comparared to reason dominant / contralateral in group (1), confirming the unbalance among the members in the experimental group.In the control group the variabily was much smaller than the difference obtained in the limbs tested, showing this to be an auxiliary instrument in prescription an evolution of rehabilitation treatments
