Primary Outcome Measures:

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

Secondary Outcome Measures:

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

Estimated Enrollment:	30
Study Start Date:	November 2002
Study Completion Date:	July 2006

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.
