Clinical Trial Summary

Peripheral facial palsy affects 15 to 40 people per 100,000 inhabitants and induces important functional and social repercussions. Synkinesis is a frequent after-effect of facial palsy recovery, consisting of involuntary facial spasms that disturb the gestural harmony and can go as far as a painful hypertonic spasm. More than 55% of patients recovering from facial palsy will develop transient or permanent synkinesis. These facial hypertonias have two main causes: imperfect axonal regeneration, which is all the more important as the damage is proximal, and hyperexcitability of the facial nerve nucleus due to a lack of central control. Management is therefore essential for the functional restoration of the face, especially since synkinesis do not evolve spontaneously. The main treatments are currently botulinum toxin injection, acting on the motor plate, and functional rehabilitation, consisting on local muscle relaxation and central motor control work. In recent years, therapies based on biofeedback and acting on central motor control have shown interesting results, and technological advances in virtual reality have made it possible to deepen this treatment in patients suffering from stroke, limb trauma or Parkinson's disease. In this project, the investigators evaluate the contribution of virtual reality to the management of facial palsy, and hypothesize that self-rehabilitation using this technology will improve motor control of the skin muscles and reduce complications related to their hypertonia such as synkinesis.
