Abstract

Purpose : The purpose of this study was to investigate effects of repetitive hand task on upper extremity proprioception and dexterity. Methods : Experimental group who had done hand task since last 1 year and young adult control group was recruited this study. Proprioception was measured positioning errors of elbow and wrist on three dimensional coordinate system by Winarm software(Zebris Medcal GmbH, Germany). And dexterity was measured by box and block test. Statistical analysis was used independent t -test. Results : When elbow moved from flexion to extension, there were significant difference on error of x axis in wrist location and erros of x, z axis in shoulder location(p<.05). When wrist moved from flexion to extension, there was significant difference on y axis in finger location error(p<.05). And there significant difference on dexterity(p<.05). Conclusion : In conclusion, repetitive hand task increase upper extremity proprioception and dexterity. The physical therapy in industrial workers should inhibit overuse injury.
