Abstract

The present two studies evaluated the effects of automatically delivered stimulation
for walker-assisted step responses with four persons with multiple
disabilities. In Study I, the participants (two children) wore two optic sensors
at their heels, which were activated by the performance of steps. Each
sensor activation produced a 2.5-s stimulation during the intervention and
post-intervention periods. In Study II, the participants (two adults) wore a
single optic sensor at their right leg. Sensor activation produced 5 or 6 s of
stimulation during the intervention phases. Data were satisfactory with both
technical arrangements (i.e., with one or two sensors); all four participants
had significant increases in step responses and indices of happiness during
the intervention phases. The two children of Study I retained these effects
at a 1-month post-intervention check programmed for them. The effects of
the stimulation procedure on aberrant behavior (assessed only in Study I)
were mixed.
