Impact of Breather Device on Ventilatory Effort in Patient With MTMD

PURPOSE: The purpose of the study is to investigate the effect of the breather device on ventilatory effort and in patients with myogenic temporomandibular joint disorders To investigate the effect of the breather device on craniocervical angle and oral Health quality in patients with myogenic temporomandibular joint disorders BACKGROUND: TMDs affect between 5% and 12% of the population which is presented by symptoms such as pain in the masticatory muscles with a decrease in the mandible's movement. Other symptoms include ear pain, headache, joint sounds with mandible movement, and/or functional limitations in the jaw like swallowing difficulties commonly found. (Hatice ., et al 2023) Increased prevalence of TMDs has been linked to physical, psychological, and hormonal changes throughout pubertal development. The age predisposes to the development of masticatory system problems in students since symptoms peak between the ages of 20 and 40 years. Women of breeding age are the majority of TMD sufferers. The prevalence of TMD increases globally throughout adolescence and may vary from 7% to 30% of the population (Loster ., et al2017). Alterations of body posture, upper thoracic breathing pattern, and mouth breathing constitute causal factors for the overuse of the accessory inspiratory musculature, which generates hyperactivity and consequently, alteration of head position, and mandibular traction. (Kim., et al 2017) HYPOTHESES: There will be no significant effect of the breather device on ventilatory effort in patients with myogenic temporomandibular joint disorders. There will be no significant effect of the breather device on a craniocervical angle and oral Health quality in patients with myogenic temporomandibular joint disorders RESEARCH QUESTION: Does the breather device can improve ventilatory effort in patients with myogenic temporomandibular joint disorders?.
