A new microswitch to enable a boy with minimal motor behavior to control environmental stimulation with eye blinks

This study assessed whether a boy with profound multiple disabilities and minimal motor behavior would be able to control environmental stimulation using repeated eye blinks with a newly developed microswitch (i.e. an electronically regulated optic sensor mounted on an eyeglasses frame). The study was carried out according to an ABAB design and included a 3 month post‐intervention check. Data showed that the boy had a large increase in the target response (repeated eye blinks) to activate the microswitch and produce environmental stimulation during the B (intervention) phases. This performance was maintained at the post‐intervention check. Practical and developmental implications of the findings were discussed. Copyright © 2005 John Wiley & Sons, Ltd.
