Plain English Summary
Background and study aims
Bell's palsy is a weakness or lack of movement affecting one side of the face. The aim of this study is to assess the feasibility of a future larger study on the Mirror Effect therapy for patients with Bell’s palsy. Most patients with Bell’s palsy recover completely. However, symptoms might persist over time, which often result in facial deformity and reduced mouth mobility. Therefore, people with such symptoms might experience changes in swallowing and speaking, which could impact their quality of life and self-esteem. In the present study, the researchers are assessing the impacts of early speech therapy on overall recovery and prevention of complications, called facial synkinesis. Synkinesis is defined as involuntary facial movements that occur while attempting to move another part of the face. This study is recruiting a small number of patients to be able to obtain an estimate of the effectiveness of the new therapy called the Mirror Effect Plus Protocol (MEPP). The MEPP will be combined with general recommendations given by the speech therapist and pharmaceutical treatment currently provided in Quebec. The researchers will compare this treatment to the usual course of treatment in Quebec, which is general recommendations given by the speech therapist and traditional pharmaceutical treatment. A positive outcome will lead to a larger study to assess the efficacy of the MEPP.
Who can participate?
Patients aged 18 and over with acute and severe Bell's palsy
What does the study involve?
Participants are randomly allocated to one of the two treatment groups to receive either the “mirror effect” treatment and the current pharmaceutical treatment recommended in Quebec, or the current pharmaceutical therapy recommended in Quebec at the moment plus counselling and a personalized exercise program 1 year after the onset of their Bell’s palsy, if needed. The severity of facial palsy is assessed at the initial assessment (10 to 14 days after onset) as well as 1, 2, 3, 4, 5, 6 and 12 months after onset
What are the possible benefits and risks of participating?
According to current knowledge, participation in this study does not involve any medical risk. Participants may get a personal benefit from their participation, but the researchers cannot guarantee it. By participating, they will be able to benefit from support and a meeting with a speech therapist experienced in the field, who will answer their questions.
Where is the study run from?
Hôpital du Sacré-Coeur de Montréal and Hôpital Maisonneuve-Rosemont (Canada)
When is the study starting and how long is it expected to run for?
September 2015 to October 2021
Who is funding the study?
1. Réseau Provincial en Adaptation – Réadaptation and the Ordre des Orthophonistes et Audiologistes du Québec (Canada)
2. Fonds de recherche du Québec- Santé (Canada)

Condition
Acute Bell's palsy
Intervention
In the present study, the researchers are recruiting a small number of patients to be able to obtain an estimate of the effectiveness of the new therapy called “Mirror Effect”. The Mirror Effect therapy will be combined with general recommendations given by the speech therapist and pharmaceutical treatment currently provided in Quebec. The researchers will compare this treatment to the usual course of treatment in Quebec, which is general recommendations given by the speech therapist and traditional pharmaceutical treatment. A positive outcome of this process will lead to a larger study to assess the efficacy of the Mirror Effect Therapy.
40 participants suffering from acute and severe Bell's palsy will be recruited and randomly attributed to one of the two treatment conditions. Assignation to the control group or MEPP group is performed by an external researcher who was not in direct contact with the patients, through computerized balanced block randomization. Thus, the 20 participants attributed to the experimental condition will receive the “mirror effect” treatment and the current pharmaceutical therapy recommended in Quebec, while the 20 other participants will be assigned to the control condition, which is the current pharmaceutical therapy recommended in Quebec at the moment plus counselling.
Treatment group: All participants receive the MEPP, a facial rehabilitation consisting of facial counselling and retraining during four in-clinic sessions during the first 2 weeks following the initial assessment. Each patient first receives information about facial function and anatomy. They then practise motor imagery (see Eaves et al., 2016) and receive passive soft tissue manipulation (Diels & Beurskens, 2014). Subsequently, specific facial exercises are explained and executed with the help of a free webpage (https://www.webcamtoy.com or MEPP web site https://mepp.marcottelab.ca/auth/signin) that provides modified visual biofeedback and a symmetrical image of the patient’s face generated by duplicating the healthy side. Instructions for facial exercises are provided to promote facial motor learning using small specific movements, emotional cueing, exercise randomization, and proper pacing. Exercises are continued at home twice daily until recovery was achieved.
Control group: The control group receive basic counselling such as instructions for avoiding excessive facial movements; however, participants did not attend therapy sessions. The control group will also receive a personalized exercise program 1 year after the onset of their Bell’s Palsy if needed.
For both groups: The first assessment is performed 10-14 days after BP onset and prior to any intervention or therapy. Reassessments are performed 1, 2, 3, 4, 5, 6 and 12 months after onset.
