title: Extracorporeal magnetic innervation therapy: assessment of clinical efficacy in relation to urodynamic parameters.
abstract: OBJECTIVE
  Clinical efficacy and urodynamic changes in women treated by extracorporeal magnetic innervation therapy (ExMI) were studied.
  
  
  METHODS
  Women, presenting with urge, stress and mixed urinary incontinence, were included in a prospective study. ExMI was applied by an electromagnetic chair. To document clinical efficacy, a voiding diary and visual analogue scale were completed before and after treatment, together with a pad test. Detrusor overactivity (DO) and urethral instability (URI) were urodynamically documented. Clinical success was defined as more than 50% improvement in symptoms.
  
  
  RESULTS
  Sixteen patients were included. At baseline, DO was observed in 10 patients, and URI in 12 patients. DO did disappear at follow-up in 60%, and a decrease in URI was seen in 66%. No significant clinical improvement was seen at follow-up.
  
  
  CONCLUSIONS
  Although significant changes in urodynamic variables were observed, no significant improvement in clinical efficacy was seen after ExMI.
