What this trial studies

This observational study aims to evaluate the effects of obturator nerve cryoneurotomy on clinical measures in adult and pediatric patients suffering from hip adductor spasticity. Conducted at the Victoria General Hospital's multidisciplinary spasticity clinic, the study will assess how effective cryoneurotomy is in alleviating spasticity and improving the quality of life for patients. Data will be collected from patients who are receiving this procedure as part of their standard treatment, providing insights into the duration of effectiveness before nerve regeneration occurs.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 12 and older who are scheduled to receive cryoneurotomy as part of their treatment for spastic hip adductors.

Not a fit: Patients with a history of previous nerve procedures or other neurological conditions unrelated to spasticity may not benefit from this study.

Why it matters

Potential benefit: If successful, this procedure could significantly improve mobility and independence for patients with hip adductor spasticity.

How similar studies have performed: While similar approaches have been explored, this specific application of cryoneurotomy for hip adductor spasticity is relatively novel.
