Further study details as provided by VA Office of Research and Development:

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.

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Diagnosed with a traumatic spinal cord injury

  • Level of injury is at T6 or below
  • Injured at least 6 months prior to study enrollment
  • Male, aged 18 to 70 years
  • Spasticity to a degree that either anti-spasticity medications have been or are being used or current spasticity is at 2 or greater on the Ashworth scale specifically for the quadriceps muscle group (knee flexion)

Exclusion Criteria:

  • Medical instability
  • Subjects may not use Cialis
  • Use of Viagra, Levitra, Caverject, or vacuum constriction devices is restricted to no less than 8 hours prior to daily vibratory therapy
  • Recent history of autonomic dysreflexia secondary to sexual stimulation
  • Presence of intrathecal Baclofen pumps
  • Inability or unwillingness to use the therapy daily
