The author investigated the property of the muscle tension control in the isometric condition without external feedback. The integrated electromyogram was recorded from electrodes on the hand muscles (m. interosseus dorsalis manus primi, m. abductor digiti minimi manus). Subjects accomplished a series of tasks in which they controlled their muscular tension with movements of a target on a computer. The effects of direction of tension (increase and decrease) were studied under various conditions including different control velocity, different types of visual guide on the screen, and range of muscle tension required. The results showed that in the decrease phase the results of all subjects fitted to the exponential curves in any other conditions. However, in the increase phase the data did not fit well, and no specific patterns appeared. The results are ascribed to the property of muscle control (feedback control and feedforward control), and discussed in relation to the mechanism of the force sensation.
