| Research Abstract |
The purpose of the present study is to elucidate the relationship between the laterality of chopstick manipulation and vision-recognition feed-back system in healthy human subjects. The effects of training on the transfer time of the stick sample by chopsticks in the dominant hand non-dominant hand were examined in the vision-free and vision cutoff conditions. In the present study, electromyograms of flexor pollicis brevis, flexor digitorum superficialis, brachio radialis and flexor carpi radialis muscles discharged during hand flexion, hand extension and pickup of stick sample with chopsticks were analyzed before and after training. From these results, training of chopstick manipulation improved nerve-muscle coordination.
