Primary Outcome Measures:
  • Global Response Assessment [ Time Frame: After 12 weeks of therapy ] [ Designated as safety issue: No ]
    Improved score on the Global Response Assessment (GRA) scale after 12 weeks of therapy. A score of 2 (moderately improved) or 3 (markedly improved) constitutes a responder on the 7 point scale


Secondary Outcome Measures:
  • Urinary Frequency [ Time Frame: After 12 weeks of therapy ] [ Designated as safety issue: No ]
    Change in Urinary Frequency (Voiding Diary) from Baseline to 12 weeks

  • Urinary Incontinence [ Time Frame: After 12 weeks of therapy ] [ Designated as safety issue: No ]
    Change in Urinary Incontinence (Voiding Diary) from Baseline to 12 weeks

  • Overactive Bladder Symptoms (OAB-q SF) [ Time Frame: After 12 weeks of therapy ] [ Designated as safety issue: No ]
    Change in Overactive Bladder Symptoms (OAB-q SF) from Baseline to 12 weeks


Enrollment: 8
Study Start Date: October 2009
Study Completion Date: June 2010
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: EMKinetics non-invasive Magnetic neurostimulator
    Patients will be treated with 12 weekly sessions of magnetic stimulation of the posterior tibial nerve at 20 hz using the EMKinetics non-invasive Magnetic neurostimulator.
