Study Details

Brief summary:

The purpose of this research study is to evaluate the effectiveness of functional electrical stimulation (FES) provided by an implanted pulse generator (IPG) in correcting hip, knee and ankle function to improve walking in people with partial paralysis.

Interventions and Outcome Measures

Arms

experimental: Experimental

Volunteers are evaluated for appropriateness for inclusion in the study on an intent-to-treat basis. Qualifying candidates all receive the implanted neuroprosthesis and participate in post-operative training and follow-up procedures

Interventions

IRS-8 (8 channel implanted receiver stimulator)

Surgical implantation of an 8 channel pulse generator to stimulate paralyzed muscles of the lower extremities

Primary outcome measure

  • The effect of functional electrical stimulation of the hip, knee and ankle muscles to improve walking in people with partial paralysis [ Time Frame: up to 36 months ]
