This study assessed small hand-closure movements as a potential response for microswitch activation with two participants with profound multiple disabilities of 5.2 and 20.6 yr. of age. The microswitch consisted of a two-membrane thin pad fixed to the palm of the hand and a control system. The outer membrane (the one facing the fingers) was a touch-sensitive layer; the inner membrane was activated if the participant applied a pressure of over 20 gm. The activation of either membrane triggered an electronic control system, which in turn activated one or more preferred stimuli for 6 sec. except in baseline phases. Each participant received an ABAB sequence, in which A represented baseline and B intervention phases, and a 1-mo. postintervention check. Analysis showed both participants increased their responding during the intervention phases and maintained that responding at the postintervention check. Implications of the findings are discussed.
