Promoting foot-leg movements in children with multiple disabilities through the use of support devices and technology for regulating contingent stimulation.

The present study assessed the possibility of promoting pre-ambulatory foot-leg movements in children with multiple disabilities by motivating their action through contingent stimulation combined with a support device. Two children aged 10 and 8 years participated. Microswitch technology (i.e., pressure sensors under the shoes or optic sensors at the front-inner side of the shoes) served for detecting the foot-leg movements and providing contingent stimulation on their occurrence. Sensor activation produced 5 s of stimulation during intervention. Data showed that both children had significant increases in foot-leg movements during the intervention phases. Implications of the data in terms of skill acquisition and further intervention prospects are discussed.
