Comparing conventional physiotherapy with functional electrical stimulation therapy for C5 palsy

Conventional-therapy & FES-therapy In-Veritas Effects Study (C-FIVE Study): Rehabilitation of the Upper Extremity for New Persistent C5 Palsy After Surgical Treatment of Patients With Degenerative Cervical Myelopathy

NA · University Health Network, Toronto · NCT05247450

This study tests if combining regular physiotherapy with electrical stimulation helps people with C5 palsy recover better than just using regular physiotherapy alone.

What this trial studies

This clinical trial aims to evaluate the effectiveness of conventional physiotherapy alone versus a combination of conventional physiotherapy and functional electrical stimulation therapy (FES-t) along with task-specific training for patients with persistent C5 palsy. The study will assess improvements in functional and neurological recovery, as well as changes in neural connectivity and excitability using neurophysiological tests and functional MRI analysis. Participants will be randomly assigned to one of the two treatment groups to determine which approach yields better outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with new unilateral or bilateral persistent C5 palsy for at least three months following surgical treatment for degenerative cervical myelopathy.

Not a fit: Patients with contraindications for FES-t, neurophysiological testing, or MRI scanning, as well as those with uncontrolled cardiovascular conditions or other significant medical issues, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective rehabilitation strategy for patients suffering from C5 palsy, potentially leading to improved functional recovery.

How similar studies have performed: Other studies have shown promise in using functional electrical stimulation therapy for rehabilitation, suggesting that this approach may yield beneficial results.
