Summary

Many people with overactive bladder (OAB) continue to experience symptoms despite pharmacologic treatment. This study evaluates the use of the ZIDA Control Sock, an FDA-cleared, noninvasive wearable device that delivers mild electrical stimulation near the ankle, as an adjunct to usual care. Adults with OAB-wet who remain symptomatic on stable medication will use the device at home once weekly for 12 weeks while continuing their prescribed therapy. The study collects clinical, patient-reported, and safety information during adjunctive device use.

Detailed description

This study evaluates the use of a home-based neuromodulation device as an adjunct to standard pharmacologic therapy for overactive bladder with urgency urinary incontinence. The ZIDA Control Sock is an FDA-cleared, noninvasive wearable device that delivers low-level electrical stimulation near the ankle to stimulate peripheral nerves involved in bladder control. The study is conducted as a prospective, single-arm clinical investigation in which participants use the device at home while continuing usual care. Device use is prescribed once weekly for 12 weeks. Study conduct includes participant training, remote support to ensure correct device use, and ongoing safety monitoring. The study is designed to characterize changes observed during adjunctive device use, assess participant experience with home-based therapy, and evaluate device-related safety. Findings will contribute to understanding the feasibility and potential clinical role of wearable neuromodulation as an add-on treatment option in routine overactive bladder care.
