Background and study aims
The overactive bladder affects 4 out of 10 people, causing a huge economic burden and severely affects daily life. This medical condition impairs the quality of life of people as it causes sudden urges to urinate and involuntary loss of urine. Medications are the most used treatment but they have several adverse effects. There is new technology named neuromodulation (stimulating nerve activity) that may have a better impact on overactive bladders with no medical risks and a longer lasting impact. One of this technique called Tibial Nerve Stimulation which uses punctures in the leg in certain points specified by Chinese acupuncture called Splen-6 or Sanyinjiao. This procedure is painless, fast and has success in 60.6% of people, lasting as long as 24 months, with minimum adverse effects. The aim of this study is to evaluate the effects of a short number of sessions of Tibial Nerve Stimulation in persons who are suffering of overactive bladder.
Who can participate?
Adults over 18 years and older who are suffering overactive bladder
What does the study involve?
Participants are assigned to one of three groups. Those in the first group receive a single session of PTNS. Those in the second group perceive six sessions of PTNS over a two week period. Those in the last group receive a single dummy PTNS. Participants are followed for six 6 months. Each participant is asked to keep diaries documenting how many times they experience overactive bladder symptoms to assess the impact of their condition.
What are the possible benefits and risks of participating?
Participant may benefit from having the treatment for free, a no charge medical consultation and from having 24 hour access by phone to a Doctor. The participants who have the treatment have the possibility to reduce their symptoms in at least 60%. The risks are minimal like small pain or bleeding in the point of puncture as the procedure is painless.

Scientific title | Percutaneous Tibial Nerve Stimulation (PTNS) for patients with overactive bladder syndrome: effect of number of sessions and gender |
Study acronym | PTNS2016SHORT |
Study objectives | The effect of Percutaneous Tibial Nerve Stimulation (PTNS) in overactive bladder (OAB) syndrome patients depends of the number of session and the gender of the participant. |
Ethics approval(s) | Ethical Committee of Litomovil del Norte/Urological Avaced Center, 30/11/2015, ref: PTNS2016SHORT-30/11/2015 |
Health condition(s) or problem(s) studied | Over active bladder syndrome |
Intervention | Participants are recruiting in accordance the inclusion criteria and provide consent to participate in the protocol. Data is collected about age, evolution time, voiding diary, OABq-SD questionnaire (Part A) using an Excel database, and values processed using the statistical software SPSS 10. Participants are then non-randomly allocated to groups based on experiment design and sample size. Participants are allocated to one of three groups. Participants with a severe impact on their quality of life are not included in placebo group. Participants are blinded to which group they are allocated to. Group 1: Participants receive a percutaneous tibial nerve stimulation (PTNS) session. The PTNS procedure consists of using a 34 gauge needle electrode inserted at a 60 degree angle, 3 to 4 cm deep 34 gauge needle electrode inserted at a 60 degree angle, 3 to 4 cm deep, in a point approximately 5 cm cephalad to the medial malleolus and slightly posterior to the tibia. The device used is a Neuromuscular Electrostimulator EMS+2, STAODYN, (Staodyn, Inc, Longmont). Data is collected before and 24 hours after (PTNS) 30 minutes single session and is also again collected one, three and six months after the session. Group 2: Participants receive six 30 minute sessions of PTNS over a two week period (three sessions each week). Data is collected before the PTNS session (3 per week) and is also collected one, three and six months after. Group 3 (Placebo group): Participants receive the one 30 minute session of the placebo PTNS. This consists of using a 34 gauge needle electrode inserted at a 60 degree angle, only 2mm deep, 34 gauge needle electrode inserted at a 60 degree angle, 3 to 4 cms deep, in a point approximately 5 cm cephalad to the medial malleolus and slightly posterior to the tibia. The device is turned on but the electrode is disconnected. Data is collected before and 24 hours after the session and again at one, three and 6 months later. As of 09/10/2018: Group 4. Effect of PTNS on plevic floor muscles (PFM) in OAB patients. 18 volunteers. 14 active and 4 placebo. |
Intervention type | Mixed |
Primary outcome measure | Bladder activity (nocturia, incontinence or urgency and frequency)is measured using the patient diaries for Group 1 and Placebo Group at baseline, 24 hours, one, three and six months and for Group 2 at baseline, one, three and six months. |
Secondary outcome measures | 1. Overactive bladder symptoms are measured using OABq-SF Questionnaire Part A for Group 1 and Placebo Group at baseline, 24 hours, one, three and six months and for Group 2 at baseline, one, three and six months. 2. Overactive bladder symptoms are measured using Perception of Bladder Condition (PPBC) Questionaire for Group 1 and Placebo Group at baseline, 24 hours, one, three and six months and for Group 2 at baseline, one, three and six months |
