Single Blind, Randomized Study to Determine the Safety and the Efficacy of Using Functional Electrical Stimulation (FES) and Repetitive Task Practice vs. Repetitive Task Practice Alone in Persons Receiving Botulinum Neurotoxin Type A Injections for Upper Extremity Spasticity

Detailed Summary

FES is a form of treatment with a device to aid movement in people who have had damage to their brain or spinal cord. Small electrical impulses are used to excite/stimulate the nerves that supply paralyzed muscles. This activates those muscles, enabling them to produce basic but useful movement. Self-adhesive patches (electrodes) are placed on the skin close to the nerve that supplies the muscle and are connected by wires to a stimulator that produces the impulses. In this way, FES is used to correct the muscle weakness that is caused by injury to the brain or spinal cord. Repetitive task practice is an "activity-based" therapy program that has been shown to enhance the recovery of hand and arm functions after stroke. This therapy consists of a set of training activities that are designed by a qualified therapist specific to your functional abilities that are to be performed with the impaired hand. These activities are designed to stimulate functional improvement with repetitive practice. Spasticity is a nervous system disorder where certain muscles are continuously contracted. Botox injections are commonly used to help to reduce spasticity in areas of the body with increased muscle tone. This research is designed to look at any additional benefit that may occur when Botox injections are combined with specific occupational therapy exercises and with a device that uses functional electrical stimulation (FES) to help improve muscle function after stroke.
