Postural alterations of the shoulders, dorsal spine and hips could have an influence on the development of craniomandibular dysfunctions.
To study the influence of body posture on the prevalence of craniomandibular dysfunction.
One hundred thirty six dental students and 41 patients assisting to the temporomandibular joints (TMJ) clinic at the Freie Universität at Berlin, were studied. Masticator, cervical muscles, temporomandibular joints and occlusions were clinically examined. The position of shoulders and hips was measured with the use of an acromiopelvimeter.
No relationship was found between postural alterations of the hips and shoulders, articular noises and sensibility or pain while palpating the temporomandibular joints. Among students, a relationship between postural alterations of the shoulders and the sensibility or pain while palpating the TMJ, was observed. When all muscles were considered, a significant relationship between asymmetric shoulders or hips and muscular pain while palpating was observed among students.
Some symptoms, especially muscular sensibility is more pronounced in people with hip and shoulder asymmetries. This relation is more pronounced in dental students than in patients.
肩部、背部脊柱和髋部的姿势改变可能会对颅下颌功能障碍的发展产生影响。
研究身体姿势对颅下颌功能障碍患病率的影响。
对136名牙科学生和41名在柏林自由大学颞下颌关节（TMJ）诊所就诊的患者进行了研究。对咀嚼肌、颈部肌肉、颞下颌关节和咬合进行了临床检查。使用肩髋测量仪测量肩部和髋部的位置。
在触诊颞下颌关节时，未发现髋部和肩部的姿势改变、关节弹响以及感觉或疼痛之间存在关联。在学生中，观察到肩部姿势改变与触诊TMJ时的感觉或疼痛之间存在关联。当考虑所有肌肉时，在学生中观察到不对称的肩部或髋部与触诊时的肌肉疼痛之间存在显著关联。
一些症状，尤其是肌肉感觉，在髋部和肩部不对称的人群中更为明显。这种关系在牙科学生中比在患者中更为明显。
