EMG feedback for the treatment of upper-extremity dysfunction: can it be effective?
This paper examines the application of EMG feedback for upper-extremity dysfunction secondary to neurologic injury. A rationale for the use of EMG feedback to enhance rotational components of upper-limb movement, train recruitment of the prime movers, and promote inhibition of motor responses that interfere with efficient and effortless movement is presented. Specific strategies that can be used to reinforce functional movement patterns are elaborated. A case study illustrating the application of the feedback strategies is provided. Despite sensory, perceptual, and cognitive impairments, a 53-year-old left hemiplegic obtained significant clinical upper-limb functional gains when given EMG feedback in conjunction with occupational therapy.
