Electromyographic biofeedback evaluation of a computer keyboard operator with cumulative trauma disorder.
This article describes a rehabilitation approach for a keyboard operator following radial tunnel decompression and release of the extensor origin of the right elbow. Prior to the patient's returning to work, a clinical electromyographic (EMG) biofeedback device was used to determine which work activities the patient should avoid or alter to reduce strain on her affected muscles. The patient was able to return to work and noticed a considerable reduction of muscle fatigue and pain in the involved muscles. A relatively inexpensive EMG biofeedback device was employed to evaluate the patient's muscles prior to returning to work. The rationale and suggestions for application of the biofeedback unit are discussed.
