Effect of prolonged Stretch Exercise of upper Extremity Muscles on both Arm and Hand of Cooperative Motion

摘要

Stretching of muscles before and after sports and/or for rehabilitation increases some physical effects and the recovery from fatigue. Many of the movement of hands and fingers in occupational therapy are harmoniously practiced. It is not clear weather stretching of skeletal muscle is effective for organized fi ne motion of fi ngers and arms. This study was carried out to examine the hypothesis that cooperative movement of bilateral arms would improve by a stretching. The speed of cooperative movement was increased and tension of the forearm muscles were decreased by stretching of the skeletal muscle. An increase effect of movement within a period in cooperative motion was recognized by stretching. It is conceivable that the effect of physical movement by relaxation of muscles was stimulated the cooperative motion. On the other, the increased quantity of cooperative motion increases the number of errors and mistakes, and stretching did not increases the accuracy of work. We can expect the development of an intervention using stretching in occupation therapy employing fine motion of human hands and forearm movements.
