Using electrical stimulation to improve recovery in cauda equina syndrome

Can Brief Perioperative Epidural Electrical Stimulation Improve Recovery of Autonomic Function in Cauda Equina Syndrome

Not applicable Interventional University of Liverpool · NCT06416878

This study is testing if using electrical stimulation during surgery can help people with cauda equina syndrome recover better and regain functions like bladder control.

What this trial studies

This study investigates the feasibility of using brief epidural electrical stimulation (ES) during routine decompression surgery for patients with cauda equina syndrome (CES). The intervention aims to assess whether ES can enhance neuronal recovery and improve functions such as micturition in patients who do not regain function post-surgery. The study will evaluate the safety and effectiveness of delivering ES in a timely manner during the surgical procedure. If successful, this could pave the way for a larger definitive randomized controlled trial.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with cauda equina syndrome experiencing bladder, bowel, or sexual dysfunction due to acute lumbar disc prolapse.

Not a fit: Patients without bladder, bowel, or sexual dysfunction, or those with contraindications to neurostimulation, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve recovery of bowel, bladder, and sexual functions in patients with cauda equina syndrome.

How similar studies have performed: While the use of epidural stimulation has shown promise in other contexts, this specific approach for cauda equina syndrome is novel and has not been extensively tested.
