About this trial

12 adults with spastic CP will complete 6 baseline sessions and 24 down conditioning sessions held 3 times/week. All clinical and physiological assessments collected at baseline will be reassessed after study completion, and follow ups after 2 weeks, 1 month and 3 months. The soleus H reflex (electric analogue of the stretch reflex) will be elicited in all sessions. In each session, participants will complete 20 baseline trials and 225 down conditioning trials to decrease the magnitude of the H-Reflex.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Age 18 and above

Diagnosis of spastic Cerebral Palsy

Gross Motor Function Classification System level I-III

Stable medical background

Disqualifiers

Pregnancy

uncontrolled diabetes

weak dorsiflexion

History of cardiac conditions

Trial design

Design model

Single group

Treatments tested in this trial

  • Spinal reflex conditioning

    Behavioral

    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.
