Abstract :
The author studied the adaptation of simple movements to changes in load. Subjects practised rapid wrist movements until they were consistent. Then they suddenly changed the inertial load, simulated by a computer-controlled motor. Adaptation to a much larger inertia occurred over the course of a few movements. The authors studied the mechanisms of adaptation using a model of the movement system and by analyzing electromyograms. Compensation for the larger inertia involves components from muscle mechanics, reflexes, and high-level neural compensation. Adaptation of the control pattern occurs during the next few trials.<>
