Summary

This study tests whether women living in rural areas can use a simple TENS device at home to reduce overactive bladder symptoms. Thirty-eight women will apply mild electrical stimulation to a nerve in their ankle for 30 minutes, three times a week for 12 weeks. Researchers will track changes in bladder symptoms and quality of life using questionnaires and voiding diaries.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Transcutaneous Tibial Nerve Stimulation (TTNS) via a TENS unit
What this could lead to
If it works, this could offer a convenient, non-drug option for managing overactive bladder at home, especially for women in rural areas with limited access to clinics.
What could go wrong
This is a small, early feasibility study with only 38 participants and no comparison group. Results may not apply to everyone, and the treatment might not provide significant symptom relief.
