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.

本研究的目的是阐明正常人的视觉操纵偏侧性与视觉识别反馈系统之间的关系。在无视觉和视觉截断条件下，考察了训练对筷子在优势手和非优势手之间传递时间的影响。本研究分析了训练前后拇短屈肌、指浅屈肌、桡侧臂肌和桡侧腕屈肌在屈手、伸手和夹持筷子时的肌电图。从这些结果来看，推拿手法的训练改善了神经肌肉协调。
