Abstract
BACKGROUND: Patients with facial paralysis are significantly limited in their quality of life (QoL). If no irreversible nerve damage is apparent, intensive training of the facial muscles is recommended in addition to drug-based therapy with cortisone. In order to improve training, we have developed a digital biofeedback mirror with motion magnification to indirectly influence the vegetative nervous system. OBJECTIVE: The aim of this work was to evaluate the reliability of the biofeedback program compared to clinical examination and classification according to House-Brackmann. METHODS: Our biofeedback system is similar to a mirror with the additional advantage of increasing a patient's self-control. It not only reflects the patient's image, but also potentiates movement through video processing and a magnifying function. For this purpose, patient's facial movements are filmed and amplified in real-time. Thus, even the smallest movements can be made visible and measured so that patients receive feedback on nerve regeneration. This can increase patient's motivation for daily facial muscle training and improve compliance. RESULTS: In the present study, restriction of QoL was evaluated and objectivized with Facial Clinimetric Evaluation Scale (FaCE) and Facial Disability Index (FDI) questionnaires. It was demonstrated that the patients' self-perception was associated with poor QoL. CONCLUSION: In the current study, measurement of the facial movements showed a reliable agreement with the clinical classification according to House-Brackmann. The biofeedback system is a reliable support tool during the regeneration phase in patients with facial paralysis..
