  • Diagnosed with OAB symptoms (characterized by urinary urgency, with or without UUI),
  • Symptoms persisting for at least 3 months, and
  • Documented with 2 or more urgency episodes per day (with or without incontinence) in two 3-day bladder diaries and,
  • With at least 11 or more voids per day (urinary frequency) documented in two 3-day bladder diaries
  • Willing and capable of providing informed consent
  • Capable of participating in all testing associated with this clinical investigation

Exclusion criteria

  • Patients with pacemakers or implanted defibrillators or any other implanted electronic device
  • Patients prone to excessive bleeding

  • Patients who are pregnant or planning to become pregnant while using this product
  • Patients with ankle joint problems, ankle oedema or dermatological oedema in the area where the electrodes should be placed
  • Patients wearing a metal implant near the stimulated area
  • Patient with cognitive deficiency
  • Administration of intravesical injection of botulinum toxin within 12 months of study enrollment, or treatment within the previous year with other forms neuromodulation for OAB
  • Patients treated with medical therapy OAB treatment washout inferior to 30 days
  • Patients with diabetic neuropathy
  • Patients with uncontrolled diabetes and HbA1c levels above 7%
  • Guillain-Barré syndrome
  • Chronic inflammatory demyelinating polyneuropathy (CIDP)
  • Multiple sclerosis
  • A primary diagnosis of stress urinary incontinence (SUI)
  • Patients with recurrent rrinary tract infections (UTIs) defined as more than 2 episodes per year, or with any baseline lower urinary tract pathology identified at the time of the 3-day bladder diary assessment.
  • Currently participating in another clinical trial

Treatment and study plan

Tensi+

Device

Transcutaneous Tibial Nerve Stimulation

Primary outcomes

  1. Treatment success

    Time frame: 12 weeks

    Percentage of responders in urgency events, where a responder is defined as a subject that either achieves a 50% or greater reduction, from baseline to Week 12, in total urgency events per day, or returns to normal (0 events per day) at Week 12. This endpoint will be evaluated through 3-day bladder diaries.

Secondary outcomes

  1. Frequency of urinary voids

    Time frame: 12 weeks

    Percentage of responders in urinary frequency, where a responder is defined as a subject that either achieves a 30% or greater reduction, from baseline to Week 12, in total urinary frequency per day, or returns to normal

  2. Urge urinary incontinence

    Time frame: 12 weeks

    Percentage of responders in urge urinary incontinence, where a responder is defined as a subject that either achieves a 30% or greater reduction, from baseline to Week 12, in total urinary frequency per day, or returns to normal (0 events per day)

  3. Overall Responder Rate Across OAB Symptoms

    Time frame: 12 weeks

    Overall Responder rate defined as the percentage of responders who meet at least the responder criteria in one of the 3 symptoms of OAB, from baseline to Week 12 (urgency, frequency and UUI) from baseline

  4. Quality of life measures

    Time frame: 12 weeks

    Measured using the OAB-q Short Form (SF) questionnaire, which includes 19 questions scored from 1 ("none of the time") to 6 ("all of the time"). The total score ranges from 19 (best QOL) to 114 (worst QOL). A decrease in score from baseline to Week 12 indicates an improvement in quality of life.

  5. Endurance of effect

    Time frame: 24 weeks

    Maintenance of responder status from the primary endpoint (Week 12) through the last follow-up visit without relapse (Week 24), indicating a sustained treatment effect until the end-of-study visit.
