What this trial studies

This study investigates the effectiveness of Transcutaneous Electric Nerve Stimulation (TENS) units in managing pain during office cystoscopic Botox injections for patients with overactive bladder. It aims to compare the pain relief provided by active TENS versus a sham TENS treatment in a double-blind, randomized, placebo-controlled design. The study is crucial as adequate pain control is essential for the success of the procedure, which is often associated with discomfort. Participants will be women aged 18 and older who are scheduled for this specific treatment and can provide informed consent.

Who should consider this trial

Good fit: Ideal candidates are females aged 18 years or older scheduled to receive Botox injections for overactive bladder.

Not a fit: Patients who have previously used TENS therapy within the last year or have certain medical conditions, such as a pacemaker or epilepsy, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management during Botox injections, enhancing patient comfort and satisfaction.

How similar studies have performed: Previous studies have shown success in using TENS for pain management in other procedural settings, suggesting potential for effectiveness in this context.
