Electromyography (EMG) feedback techniques used in physical and occupational therapies were applied successfully in the treatment of three patients with speech/language disorders. The Hyperion Bioconditioner, Model 4080, a microprocessor-based EMG that provides on-line, real-time computation, was used to record and display EMGs from two muscle groups. Results of three case studies reconfirm the effectiveness of biofeedback for all types of neuromuscular reeducation.
