Using nerve stimulation to improve bladder function in acute spinal cord injury

Transcutaneous Tibial Nerve Stimulation in Patients With Acute Spinal Cord Injury to Prevent Neurogenic Detrusor Overactivity: A Nationwide Randomised, Sham-controlled, Double-blind Clinical Trial

NA · University of Zurich · NCT03965299

This study is testing whether a nerve stimulation treatment can help people with recent spinal cord injuries improve their bladder function and avoid related problems.

What this trial studies

This clinical trial investigates the effects of transcutaneous tibial nerve stimulation (TTNS) on patients with acute spinal cord injury (SCI) to prevent neurogenic lower urinary tract dysfunction (NLUTD). It is a nationwide, randomized, sham-controlled, double-blind multicentre trial conducted across various SCI centers in Switzerland. Participants will be randomly assigned to receive either active TTNS or sham stimulation for 30 minutes daily, five times a week, over a period of 6-9 weeks. The primary outcome is the success of the intervention in improving bladder function and preventing complications associated with NLUTD.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with acute spinal cord injury occurring within the last 40 days.

Not a fit: Patients with severe bladder dysfunction or those currently undergoing other specific bladder treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve bladder function and quality of life for patients with acute spinal cord injury.

How similar studies have performed: Previous studies have shown promise in using neuromodulation techniques for bladder dysfunction, suggesting potential success for this approach.
