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
Spinal Cord InjuryMuscle Spasticity
Procedure: Penile Vibratory Stimulation
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.
