What this trial studies

This study involves 12 adults with spastic cerebral palsy who will undergo a series of conditioning sessions aimed at reducing muscle spasticity. Participants will complete 6 baseline sessions followed by 24 conditioning sessions, where the soleus H reflex will be elicited to decrease its magnitude. Assessments will be conducted at baseline and after the intervention, with follow-ups at 2 weeks, 1 month, and 3 months. The goal is to explore a non-invasive method to improve motor function and reduce spasticity in individuals with cerebral palsy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and above with a diagnosis of spastic cerebral palsy and stable medical backgrounds.

Not a fit: Patients with uncontrolled diabetes, cognitive deficits, or recent botox treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce spasticity and improve motor function in adults with cerebral palsy.

How similar studies have performed: Previous studies have shown promising results with similar non-invasive approaches to reduce spasticity in other populations, suggesting potential for success in this study.
