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

January 20, 2009 updated by: US Department of Veterans Affairs
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.

Study Overview

Status

Completed

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
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

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