Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Despite the fact that decreased muscular extensibility and strength, increased muscular fatigability, hipomobility, and alteration of the biomechanical efficiency and length of the masticatory muscles are documented clinical consequences, no systematic method of obviating such problems through muscular rehabilitation has yet been published

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Experimental group
Inclusion criteria were: Skeletal Class III orthognathic surgery patients; adults (age above 18 years), agreement to perform orthognathic surgery and to undergo all of the necessary procedures determined by the multidisciplinary team (i.e. orthodontic preparation, clinical orofacial myofunctional and electromyographic assessment, surgery, post surgery orthodontic treatment, post surgery clinical orofacial myofunctional and electromyographic assessment and orofacial myofunctional treatment when necessary). Exclusion criteria were: previous orthognathic surgery; previous head and neck surgery; neurologic and/or systemic diseases; facial trauma; syndromes; cognitive impairment; and communication and hearing deficits.
orofacial myofunctional treatment protocol
Once a week for six weeks, the experimental group received a forty minutes session of orofacial myofunctional treatment. A home exercise program was prescribed during each session. The protocol implies in continuous and daily practices - participants were asked to perform exercises at least three times a day. After the first six weeks, the experimental group underwent four sessions for maintenance purposes (two sessions twice a month and two sessions once a month). The total treatment duration was of five months.
Instruction Group
Inclusion criteria were: Skeletal Class III orthognathic surgery patients, adults (age above 18 years), agreement to perform orthognathic surgery and to undergo all of the necessary procedures determined by the multidisciplinary team (i.e. orthodontic preparation, clinical orofacial myofunctional and electromyographic assessment, surgery, post surgery orthodontic treatment, post surgery clinical orofacial myofunctional and electromyographic assessment and orofacial myofunctional treatment when necessary). Exclusion criteria were: previous orthognathic surgery; previous head and neck surgery; neurologic and/or systemic diseases; facial trauma; syndromes; cognitive impairment; and communication and hearing deficits.
counseling
The instruction group underwent two supervised forty minutes therapy sessions along the six weeks following surgery. These sessions involved the perception of the stomatognathic system, especially in terms of adequate performance during mastication. Specific exercises were not given and patients were instructed to try to reproduce the adequate pattern of mastication at all meals (i.e. alternated bilateral, with lip closure; with coordination activity of the tongue and mandible).
Control group
Inclusion criteria for this group were: adults (age above 18 years); absence of stomatognathic system alterations; absence of alterations in the scapular region; complete permanent dentition (absence/extraction of the third molar was accepted); Skeletal and Angle's Class I facial pattern; and absence of malocclusion. Exclusion criteria were: previous orthodontic treatment; and history of previous oral motor intervention.
Control Group
As the sEMG test-retest is a critical issue, participants of CG were also tested in two distinct moments (testing occurred with 1 year interval) in order to verify possible changes in the sEMG measurements as a result of retesting.
