Understanding the use of the MEPP 2.0 website in facial rehabilitation

INTERVENTION: The MEPP for rehabilitation of peripheral facial palsy The MEPP is based on relevant components from two existing facial rehabilitation protocols: The Mirror Effect Protocol and the Neuromuscular Retraining protocol, and allows the combined advantages of both interventions. It first includes the use of a modified visual‐feedback mechanism to help decrease cortical sensory‐motor disturbances that occur in peripheral facial palsies. Interestingly, the MEPP has been shown to be effective. Also, components of the Neuromuscular Retraining protocol were included in the MEPP. For chronic Bell's palsy, Neuromuscular Retraining is the gold standard for facial rehabilitation. It mostly consists of re‐learning adequate facial movements through individualized, slow, and specific facial exercises. However, many authors consider that the use of modified visual feedback during NMR could further improve facial function and increase patients’ compliance. To provide the MEPP and its modified visual feedback, an open‐source and free website was developed. In its first version, the MEPP website used the central axis of the image to duplicate the patients’ faces, and users reported difficulties in maintaining facial stability while performing facial exercises. Therefore, we developed a second version of the MEPP website, called MEPP 2.0, that incorporates augmented reality techniques, and that could potentially improve user experience and concentration on facial tasks. Since augmented reality technology provides a more organic and realistic face rendition, it could also have positive impacts on embodiment and motor learning, which are core principles in MEPP therapy. Assessing patients’ and clinicians’ perceptions is cruci CONDITION: Facial rehabilitation in patients with facial palsy ; Nervous System Diseases PRIMARY OUTCOME: User experience of clinicians and patients with website MEPP 2.0 and with MEPP 1.0 (crossover) measured using the standardized MeCUE questionnaire after 2 to 4 weeks of use for each website SECONDARY OUTCOME: ; 1. Adherence to treatment for patients measured using the number of completed sessions recorded by the websites after 2 to 4 weeks of use for each website; 2. Embodiment for patients measured using the standardized Virtual Embodiment Questionnaire (VEQ) after 2 to 4 weeks of use for each website; 3. Modulating factors of clinical practice for clinicians measured using standardized interviews after 2 to 4 weeks of use for each website; INCLUSION CRITERIA: Patients with facial paralysis: 1. Aged 18 years old and over 2. Suffer from peripheral facial paralysis 3. Have used or agreed to use the MEPP 1.0 and the MEPP 2.0 in the clinic or during a standardized trial to obtain enlightened comparative impressions of the two tools 4. Speak and read enough French and/or English to be able to answer an interview and standardized questionnaire. Clinicians working with customers with facial paralysis: 1. Aged 18 years and over 2. Having used the MEPP 1.0 and the MEPP 2.0 in the clinic or during a standardized trial allowing to obtain comparative impressions enlightened on the two tools 3.
