과활성 방광에 대한 이동형 경피 경골 신경 자극의 효과성
과활성 방광 환자에서 기존 프로토콜과 비교한 이동식 경피 경골 신경 자극의 효과를 평가하는 단일 기관 무작위 대조 시험
The goal of this clinical trial is to learn if using a portable nerve stimulation (TENS) device during daily life works to reduce overactive bladder (OAB) symptoms in adults aged 18 to 65. The main questions it aims to answer are:
- Does using TENS at home during daily activities reduce the number of urgency episodes?
- Does this approach improve bladder symptoms and quality of life as much as clinic-based treatment?
Researchers will compare two ways of using TENS applied to the ankle area (tibial nerve stimulation):
- Group 1 (Clinic-based): Participants will visit the clinic twice a week for 2 weeks and receive 30-minute TENS sessions.
- Group 2 (Ambulatory): Participants will use a portable TENS device at home during their daily routine when they feel the urge to urinate, over a 2 week period.
Both groups will use the same electrical settings (20 Hz frequency, 200 µs pulse width).
Participants will:
- Complete bladder symptom questionnaires before and after the study
- Fill in a 3-day voiding diary to track how often they urinate, urgency episodes, and any leakage
- Answer quality of life questions at the start and at 4 weeks

상세 설명
Overactive bladder (OAB) is a common condition that causes a sudden, strong need to urinate. It may also cause frequent urination during the day and night, and sometimes urine leakage. Transcutaneous tibial nerve stimulation (TTNS) is a safe, non-invasive treatment that uses mild electrical impulses through the skin near the ankle to calm bladder activity. The posterior tibial nerve at the ankle shares the same spinal nerve roots (L4-S3) that control the bladder.
Current TTNS protocols require regular clinic visits on a fixed schedule. This study introduces an ambulatory approach where participants use a portable TENS device in their daily life when urgency symptoms occur, rather than attending scheduled clinic sessions.
This is a prospective, single-center, randomized controlled trial conducted at Başakşehir Çam and Sakura City Hospital, Istanbul, Turkey. A total of 30 to 50 adults aged 18 to 65 with a clinical diagnosis of OAB who have not improved enough with lifestyle changes and behavioral therapy will be enrolled.
Participants will be randomly placed into one of two groups:
Group 1 - Conventional TTNS: Clinic-based sessions, twice per week for 2 weeks (4 sessions total), each lasting 30 minutes.
Group 2 - Ambulatory TTNS: Participants will receive a portable TENS device and use it at home during daily activities when they experience urgency, over a 4-week follow-up period.
Both groups will use the same stimulation settings: 20 Hz frequency and 200 µs pulse width. Two surface electrodes will be placed over the posterior tibial nerve near the inner ankle. The intensity will be set at a comfortable level just below the point that causes muscle movement.
Outcomes will be measured at baseline and at 4 weeks using OAB symptom scores (OAB-V8 and/or OABSS), a 3-day voiding diary (urinary frequency, urgency episodes, incontinence episodes), and quality of life questionnaires. Treatment adherence, patient satisfaction, and any side effects will also be recorded.

활성 비교기: Conventional Clinic-Based TTNS
Participants will receive transcutaneous tibial nerve stimulation (TTNS) at the clinic twice per week for 2 weeks (4 sessions total). Each session will last 30 minutes. Two surface electrodes will be placed over the posterior tibial nerve near the inner ankle. Stimulation parameters will be set at 20 Hz frequency and 200 µs pulse width, with intensity adjusted to the highest comfortable level below the motor threshold. |

실험적: Ambulatory Self-Administered TTNS
Participants will be provided with a portable TENS device and instructed to self-administer TTNS during their daily activities when they experience urgency symptoms over a 2-week period. Two surface electrodes will be placed over the posterior tibial nerve near the inner ankle. Stimulation parameters will be set at 20 Hz frequency and 200 µs pulse width, with intensity adjusted to the highest comfortable level below the motor threshold. Participants will receive training on correct electrode placement and device use at the first visit. |

Change in Overactive Bladder Symptom Score (OABSS)
기간: Baseline and 4 weeks
|
OABSS is a 4-item self-administered questionnaire measuring the frequency of daytime urination, nighttime urination, urgency, and urgency urinary incontinence. Total score ranges from 0 to 15. Higher scores indicate more severe OAB symptoms and worse outcome. |

Description: OAB-V8 is an 8-item patient-reported questionnaire assessing the bothersomeness of overactive bladder symptoms. Each item is scored from 0 (not at all) to 5 (a very great deal), yielding a total score ranging from 0 to 40. Higher scores indicate greater symptom burden and worse outcome. |

Patient Satisfaction - Patient Global Impression of Improvement (PGI-I)
기간: 4 weeks
|
Description: The PGI-I is a single-item patient-reported outcome measure assessing the patient's perception of overall improvement following treatment. The scale ranges from 1 to 7, where 1 = "very much better" and 7 = "very much worse." Lower scores indicate greater patient satisfaction and better outcome. The PGI-I is widely used in urological and overactive bladder clinical trials to assess treatment satisfaction. |
