Further study details as provided by Rambam Health Care Campus:

Primary Outcome Measures:
  • International Index of Erectile function- Erectile Function Domain [ Time Frame: At screening and 17 weeks later at last visit ]
    An increase in score of 5points and above will be considered success.

Secondary Outcome Measures:
  • Rigidity scale [ Time Frame: At screening and 17 weeks later at last visit ]
    A change from 1,2 to a result of 3 or 4 of the rigidity scale points will be considered success

  • Flow Mediated Dilatation Technique [ Time Frame: At screening and 17 weeks later at last visit ]
    A specialized sphygmomanometer cuff located at the penile base, is inflated to 50 mm Hg for 5min to induce a venous filling. A mercury strain gauge is placed at least 1-2 cm above the penile cuff. Baseline penile blood flow is obtained. Postischemic penile blood flow is then recorded immediately after the deflation, until a return to baseline flow is observed. An increase in blood flow above 30% will be considered success.

Study Completion Date: November 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: shock wave treatment Device: "MEDISPEC" treatment probe
300 shocks in 5 different anatomical locations of the penis.
Device: "MEDISPEC" Low intensity shock waves
Treatment parameters will be as follows: Intensity: 0.09 mj/mm2 ,300 shocks per site, on 5 penile anatomical sites. Total number of shock waves: 1500/ session Frequency of 120/min
Sham Comparator: "MEDISPEC" Sham
"MEDISPEC" Probe does not deliver energy but creates same noise and sensation of active probe
Device: "MEDISPEC" Sham Probe
Sham probe applied same as treatment probe without energy
Device: Sham
Probe does not deliver energy but creates same noise and sensation of active probe
Other Name: Vasculospec
