The Muscle-Machine Interface After Stroke in Improvement of Hand Extension: Case Report
The muscle-machine interface assists in the neuroplasticity of healthy with lesions during the combination of electromyography techniques and functional electrical stimulation (EMG-FES). This case report aimed to evaluate this interface for rehabilitation in a post-stroke participant. For the treatment, an EMG-FES interface was associated with functional exercises for wrist and finger extension. This case report aimed to evaluate this interface for rehabilitation in a post-stroke participant. The protocol was applied 3x/week during 12 sessions. Were applied eliminatory tests (Mini mental exam, active range of motion and Ashworth modified scale), functional tests (Fugl Meyer scale and 9 hole peg test) and electromyography evaluation in time (EMGRMS) and frequency (EMGMDF) domain. In the functional tests occurred increase in sensibility, mobility, oriented tasks and pain reduction (18/48 to 23/48) and the electromyography showed an increase 35.12 VRMS in EMGRMS and 123 Hz in EMGMDF. This interface is effective for improving voluntary movement of hand extension after stroke.
