Could a TENS unit stop bowel accidents after spinal injury?
NCT ID NCT05626816
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether gentle electrical stimulation of a nerve in the genital area can improve bowel control in people with spinal cord injury. Researchers will measure how the rectum and anus respond to the stimulation using a small balloon. The goal is to see if this non-invasive approach could reduce fecal incontinence, a common and life-limiting problem after spinal cord injury.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Genital nerve stimulation using a TENS unit with surface electrodes
- What this could lead to
- If it works, this could point toward a non-invasive, drug-free way to reduce fecal incontinence and improve quality of life for people with spinal cord injury.
- What could go wrong
- This is a small, early-phase study (52 people) testing only short-term effects. It may not translate to real-world benefit, and not everyone responds to the stimulation.

Inclusion Criteria: * Traumatic SCI * Minimum 6 months post-injury * Aged 18 years or older * Neurological level of injury T12 or higher AIS grade A-D defined by ISNCSCI * Response to genital nerve stimulation upon screening * Able to understand and provide informed consent Exclusion Criteria: * Currently enrolled in another functional electrical stimulation (FES) research trial * Females who are pregnant or planning to become pregnant during the trial * Presence of cardiac pacemaker, implanted defibrillator or other implanted FES device if, upon clinical exam, it may have an interaction with GNS. * In the judgement of the PI or Co-Investigators, presence of medical complications that may interfere with the execution of the study.
