Biofeedback treatment of orofacial dysfunction: a preliminary study.

The American Journal of Occupational Therapy : Official Publication of the American Occupational Therapy Association

|March 1, 1978

Summary

Electromyographic biofeedback effectively aids muscle reeducation for post-stroke orofacial dysfunction. This approach, when used by allied health professionals, shows significant value in patient recovery.

Background:

Orofacial dysfunction is a common sequela of stroke, impacting speech and swallowing.
Traditional therapies aim to restore muscle function and coordination.
Novel therapeutic approaches are needed to improve outcomes for stroke survivors.

Observation:

A study compared electromyographic biofeedback (EMG biofeedback) with mirror feedback in four post-stroke patients (one quadriparetic, three hemiparetic).
Patients had varying recovery times, ranging from two months to three years post-stroke.
The study focused on the effectiveness of these interventions in correcting orofacial motor deficits.

Findings:

Results indicate that EMG biofeedback is a valuable adjunctive tool for muscle reeducation in post-stroke patients.
The study demonstrated the efficacy of EMG biofeedback when administered by trained allied health professionals.
Mirror feedback also showed potential, but EMG biofeedback appeared particularly effective.

Implications:

EMG biofeedback should be considered as a complementary therapy in orofacial rehabilitation programs.
Training allied health professionals in EMG biofeedback application can enhance patient care.
Further research is warranted to explore optimal protocols and long-term effects of EMG biofeedback for diverse stroke-related deficits.
