Experiments were carried out to discover the horizontal and veritical distribution of the hand strength pushing horizontally a knob by adduction of the upper limb and the effects of the posture of the subject. To measure the strength a straingauge dynamometer was used, the knob of which was (pushed horizontally.) with right hand by six female adults. The results are: 1) The most effective position of the knob is at 22.5°∼45° left side of the right acromion and near the front of the body. 2) In the standing posture with legs apart the performance is better and the best result is obtained with the knob placed relatively high. In the sitting posture, the lower the seat height, the better is the performance. 3) Generally speaking, the performance depends on the force spent for maintaining the posture, rotation of lower limbs, and the friction between the surface of floor and soles of feet.
