Electric stimulation to improve bladder function in spinal cord injury patients

Transcutaneous Tibial Nerve Stimulation for Spinal Cord Injury Neurogenic Bladder

NA · The University of Texas Health Science Center, Houston · NCT04350359

This study is testing if a new type of electric stimulation can help people with spinal cord injuries improve their bladder control and reduce incontinence.

What this trial studies

This study investigates the effectiveness of transcutaneous tibial nerve stimulation (TTNS) in enhancing bladder outcomes for individuals with spinal cord injuries (SCI) who experience neurogenic bladder. Participants will be randomized to receive either a fixed-dose or variable-dose of TTNS, administered at different frequencies (2 days vs. 5 days weekly). The study aims to assess the impact of these stimulation protocols on incontinence prevention and overall bladder management. Surveys will also be collected to evaluate participant characteristics and adherence to treatment throughout the study duration.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with traumatic or non-traumatic spinal cord injuries at the T9 level or above, admitted to rehabilitation within 6 weeks.

Not a fit: Patients with a history of genitourinary disorders, central nervous system disorders, or peripheral neuropathy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve bladder control and quality of life for patients with spinal cord injuries.

How similar studies have performed: Previous studies have shown promise with tibial nerve stimulation for bladder control, suggesting potential for success in this approach.
