Recent clinical reports have suggested that electromyographic feedback offers promise as a palliative therapy for neuromuscular disorders. This study utilized a single‐subject experimental analysis to evaluate the effects of EMG feedback training on a 20‐year‐old man with adult‐onset idiopathic dystonia to achieve control of orofacial dysfunctions. Feedback training produced reductions in levels and variability of tension in facial and forearm muscles, as measured by EMG. Reliable blind observations of facial control indicated that feedback training enabled the patient to produce normal facial relaxation in extraclinical environments.
