Assessing a New Response-Microswitch Combination with a Boy with Minimal Motor Behavior

This study assessed whether a boy with profound multiple disabilities and minimal motor behavior could learn to use a new response-microswitch combination to control environmental stimulation. The response selected was a chin movement; a mechanical microswitch was set up for this response. The boy learned to use the microswitch, increasing the frequency of the chin response and the level of pleasant stimulation following such response. The performance was retained at a 2-mo. postintervention check.
