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.

Background: Microswitches are the most commonly used input device for people with multiple disabilities to control environmental stimulation. However, little is known about adopting the commercial trackball with a revised trackball driver as a more feasible input device. Aims: To assess whether two children with profound multiple disabilities and minimal motor skills would be able to control environmental stimulation using thumb poke ability through cordless trackballs installed with a newly developed mouse driver (i.e. a new mouse driver replacing a standard mouse driver, turning a trackball mouse into a precise thumb poke detector). Method: An ABAB design and a 2-month post-intervention check were adopted to perform the study. Results: Data showed that the two children improved significantly in their target response (thumb poke) to activate the control system to produce environmental stimuli during the B (intervention) phases. This performance was maintained at the post-intervention check. Conclusions: The use of thumb poke in connection with a trackball allowed the children with multiple disabilities and minimal motor skills to increase their level of response and stimulation control.
