This study was designed to investigate unilateral sanding activities of stroke patients with hemiplegia.Data of the hemiplegic patients group(HG)was compared with the sanding activities of the control group of healthy adults(CG).Effects of the slope of the experimental sanding board, posture of subjects during sanding activities, block shapes, and block weight used in those activities were analyzed through surface electromyographic signals captured during the sanding activities.In the HG, electromyography(EMG)of the triceps brachia appeared more remarkably than those of the CG.While, the EMG of the deltoid of the CG was increased much more than in the HG.It was supposed that muscular work of the triceps brachia might practice upper-elevation of the shoulder with broad extension of the elbow in the HG.The results indicate that these activities would not be sufficient for muscle training of the deltoid of hemiplegia patients, and another physical activity should be adopted simultaneously for recovery of the neuro-muscular function of the deltoid.In the CG, keeping freedom of movement in the standing posture had a significant influence on muscle work of the deltoid.Additionally, the weight and shapes of the block used in the sanding activities influenced the muscle work of the tricept brachia.Especially use of a bar-shape block increased EMG of triceps brachia during supination of the forearm.
