Treatment of Facial Paralysis of Cns-Origin: Initial Studies

Abstract

Many hemiplegic patients suffer a chronic (central) facial paralysis. Usually the patients have lost voluntary control of the involved muscles, while their ability to produce spontaneous emotional expression remains intact. Electromyographical (EMG) biofeedback and Neuro Developmental Treatment (NDT) are well-documented methods for the rehabilitation of these patients. EMG biofeedback has been described and evaluated by Huffman (1978). This technique and Huffman's findings will be briefly reviewed in the current paper. The NDT method, as well as our own pilot study, are also described. Huffman found that a combination of myofeedback and mirror-feedback led to more progress than treatment with mirror-feedback alone. From the NDT study, it is clear that improvements in orofacial functioning can be achieved. In the discussion, some principles from the neurosciences are put forward to explain the results.
