Myobiofeedback in motor reeducation of wrist and fingers after hemispherial stroke.
32 patients with different grade of hemiparesis, were in the first weeks after a cerebral vascular accident treated by means of EMG-feedback in respect to volar and dorsal flexion of the wrist, flexion and extension of the fingers, and opposition of thumb to the second ev. other fingers. EMG was registered from suitable muscles of the paretic limb. The attempt of volitional movement at the paretic side was conditioned with a reinforced mirror synergia of the same type from the healthy to the damaged side. The patient observed the effect on the EMG screen. After 3-6 conditionings the patient performed the volitional movement alone. In 25 of patients (e.g. 78.1%) improvement was obtained, at least in EMG. A good correlation was found between effect of the procedures and severity of paresis (p less than 0.05; chi 2 = 7.35).
