The Use of Penile Vibratory Stimulation to Decrease Spasticity Following Spinal Cord Injury

Brief Summary:
The purpose of this study is to determine the effect of penile vibratory stimulation on the muscle spasticity of men with chronic spinal cord injury.

Condition or disease Intervention/treatment Phase
Spinal Cord Injury Muscle Spasticity Procedure: Penile Vibratory Stimulation Not Applicable

Detailed Description:
Spinal cord injury can result in mild to severe muscle spasms that can both inhibit functional capability and increase the likelihood of injury due to fall. Anecdotal reports and a recent study suggest that triggering the ejaculatory reflex in men with vibratory stimulation can result in a significant decrease in spasm activity over a period of 2 to 42 hours. This study examines the effects of penile vibratory stimulation on spasticity when conducted daily in the home setting.

Primary Outcome Measures :
  1. Spasticity in the lower extremities will be scored per the
  2. Ashworth scale at each weekly visit. Additionally,
  3. subjects will record their daily spasm frequency on a 5
  4. point scale in the form of a daily questionnaire. Intra
  5. and inter-visit indicies of spas.

Secondary Outcome Measures :
  1. Several questionnaires such as the CHART, SWLS, FIM, and IIEF are used to assess changes in quality of life and function.
