Operant Conditioning of the Soleus Stretch Reflex in Adults With Cerebral Palsy

Each participant will serve as their own control. The intervention is 30 sessions. The first 6 sessions are baseline measures of reflexes. The remaining sessions will engage participants in learning how to decrease their reflex activity in their calf muscle on the more-affected leg. Each intervention visit will involve 20 trials in which participants do not get visual feedback about their performance, then 225 trials with visual feedback.
