简要总结
The purpose of this study is to determine if Transcutaneous Tibial Nerve Stimulation (TENS) is as effective as Percutaneous Tibial Nerve Stimulation (PTNS) as therapeutic option for subjects with Idiopathic Overactive Bladder (OAB) who have failed conventional therapy.
详细描述
Both therapies have been proven to be effective, but very few times have been compared. PTNS and TENS SNS have been proven effective modifying bladder diary scores (change in the frequency of day and night urination, and urge incontinence), and improving subject's quality of life. Only PTNS has shown changes in urodynamic data while undergoing therapy.
The investigators hypothesize that short-term effectiveness and benefit reported, is not lower in the TENS group, if we compare both therapies in a randomized control trial.
Secondary goals are to evaluate changes in bladder diary scores (frequency of urination, nocturia, number of urgency and leakage episodes ), participants quality of life improvement scores and treatment benefit score at TBS scale, while undergoing these therapies.

研究组 & 干预措施
Transcutaneous Tibial Nerve Stimulation
TENS SNS therapy is performed as follows; patient is asked to sit with legs slightly bent and an adhesive electrode is attached transcutaneously 5cm cephalic to either the right or left medial malleolus (subject choice). A surface electrode is placed on the medial surface of the ipsilateral calcaneum and both electrodes are connected to a low voltage electronic stimulator. The current is then set to the highest level tolerable to the subject (0-20 mA) and subject undergoes therapy for 30 minutes and 12 weeks (once-a-week session). Data are completed at baseline, after half therapy and after 12 weeks therapy.
干预措施: TENS SNS (Device)
Percutaneous Tibial Nerve Stimulation
PTNS therapy is performed as follows; patient is asked to sit with legs slightly bent. The area where the needle will be placed is cleaned with an alcohol swab. A 34 gauge needle (equivalent to an acupuncture needle) is inserted percutaneously approximately 5 cm cephalad to the medial malleolus of the right or left ankle (subject choice) at a 60 degree angle. A surface electrode is placed on the medial surface of the ipsilateral calcaneous. The needle and electrode are connected to a low voltage electrical stimulator. The current is then set to the highest level tolerable to the subject (0-20 mA) and the subject undergoes therapy for 30 minutes and 12 weeks (once-a-week session). Data are completed at baseline, after half therapy and after 12 weeks therapy.

结局指标
主要结局
Reduction from Baseline in Urinary Frequency Scores on 3-day voiding diaries at 12 weeks
时间窗: 12 weeks
A reduction in urinary frequency was regarded clinically significant when a normal voiding pattern of less than 8 voids per 24 hours could be obtained
次要结局
- Reduction from Baseline in the number of leakage episodes diaries at 6 weeks and at 12 weeks(6 and 12 weeks)
- Change from Baseline in Mean, Moderate to Severe Urgency episodes on 3-day voiding diaries at 6 and at 12 weeks(6 and 12 weeks)
- Reduction from Baseline in Mean Nocturia Episodes on 3-day voiding diaries at 6 and at 12 weeks(6 and 12 weeks)
- Improved quality of life function via the Incontinence Quality of Life Scale (I-QOL)(6 and 12 weeks)
- Improved Bladder Symptom Severity Score via Overactive Bladder Questionnaire (OAB-q) at 6 and at 12 weeks(6 and 12 weeks)
- Degree of Satisfaction Score on the Treatment Benefit Scale (TBS) at 6 and at 12 weeks(6 and 12 weeks)
