They lead to functional disorders (i.e., disturbances in chewing or oral communication) and aesthetic issues with psychological repercussions on self-esteem, affecting the quality of life of these patients. The multidisciplinary treatment involves orthodontics (duration = 18-24 months), orthognathic surgery involving the maxillary and/or mandibular bone (at 12 months), immediately followed by physiotherapy (duration = 3 months). One main goal after surgery is the recovery of month opening to restore an appropriate orofacial function. Motor imagery (mental rehearsal of a movement without actually moving) is effectively used in athletes and in rehabilitation mainly neurological but so far has not been investigated in maxillofacial rehabilitation. Considering that the effectiveness of rehabilitation is increased when physical and mental practices are combined, this leads to propose this study aiming to investigate whether the addition of motor imagery of the maxillofacial region to maxillofacial physiotherapy (based on a practice of physical therapeutic exercises) modifies the recovery of maximum mouth opening, other ranges of motion, jaw function, and quality of life in patients after orthognathic surgery compared to the addition of a control cognitive task \[watching a non-emotional content film or filling out a crossword or Sudoku grid\] to maxillofacial physiotherapy. conditions: Maxillofacial Abnormalities studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL interventionModelDescription: Multi-centric randomized controlled trial primaryPurpose: TREATMENT masking: DOUBLE maskingDescription: A randomization list will be centrally generated by an independent methodologist for each center and integrated into the electronic case report form. The physiotherapist will disclose the allocation to the participant during the inclusion visit, following clear, transparent, and appropriate information, and obtaining the participant's consent to participate in the study. This disclosure occurs after all measurements have been completed. The inclusion visit is scheduled 30 days ± 8 before the surgery. whoMasked: INVESTIGATOR whoMasked: OUTCOMES_ASSESSOR count: 100 type: ESTIMATED name: Motor imagery of the jaw name: Control task (Sudoku or Crossword puzzle) measure: Maximal mouth opening measured in millimeters using a caliper measure: Active maximum mouth opening in millimeter using a vernier caliper measure: Active jaw range of motion (ROM) other than maximal opening measure: Maxillofacial pain measure: Body weight mass (kilograms) measure: Orthodontic associated treatment measure: Compliance with physiotherapy and intervention measure: Orofacial function measure: Maxillofacial quality of life measure: Level of achievement of the goals set by the patient before surgery measure: Motor imagery capability sex: ALL minimumAge: 18 Years stdAges: ADULT stdAges: OLDER_ADULT facility: Cabinet Bataille city: Lyon zip: 69003 country: France name: Guillaume Nainani role: CONTACT phone: 0478011908 phoneExt: +33 email: guillaume.nainani@gmail.com lat: 45.74848 lon: 4.84669 facility: Cabinet de kinésithérapie Saint Alexandre city: Lyon zip: 69005 country: France name: Caroline Alvarado-Faysse role: CONTACT phone: 0437410332 phoneExt: +33 email: c.alvarado.faysse@gmail.com lat: 45.74848 lon: 4.84669 facility: Hôpital Henry Gabrielle city: Saint-Genis-Laval zip: 69230 country: France name: Sébastien Matéo role: CONTACT phone: 0478865066 phoneExt: +33 email: sebastien.mateo@chu-lyon.fr lat: 45.69558 lon: 4.7934 hasResults: False
