Abstract

Objective: To investigate biomechanics, muscle performance, and disability of the craniocervical region in temporomandibular disorder (TMD) patients and compare them with controls.

Methods: Craniocervical posture was evaluated using lateral photography and radiography. Range of motion, muscle performance, disability, and TMD severity were assessed using an inclinometer, Functional Strength Testing of Cervical Spine, Neck Disability Index, and Fonseca Anamnestic Index, respectively.

Results: Compared to the control group, the TMD group demonstrated higher cervical flexion angle (p=0.005) and neck disability (p<0.001) as well as lower cervical extension (p=0.040), right cervical rotation (p=0.005), left cervical rotation (p<0.001), and tragus-C7-horizontal (p=0.048) angles, and reduced muscle performances (p≤0.001). Most patients had higher than normal craniocervical angle (p<0.001). Muscle performance in each cervical motion (p<0.005) and disability (p<0.001) were associated with TMD severity in the TMD group.

Conclusion: Biomechanics, muscle performance, and disability of craniocervical region were altered in the TMD group.

对颞下颌关节紊乱症患者颅颈区域的生物力学、肌肉表现和残疾程度的调查。

目的研究颞下颌关节紊乱症（TMD）患者头颈部的生物力学、肌肉表现和残疾情况，并与对照组进行比较：方法：使用侧位摄影和放射摄影评估颅颈姿势。方法：使用侧位摄影和放射摄影评估颅颈姿势，并分别使用倾角仪、颈椎功能强度测试、颈部残疾指数和丰塞卡失能指数评估患者的活动范围、肌肉表现、残疾程度和 TMD 严重程度：与对照组相比，TMD 组患者的颈椎屈曲角度（P=0.005）和颈部残疾程度（pp=0.040）、右侧颈椎旋转角度（P=0.005）和左侧颈椎旋转角度（pp=0.048）均高于对照组，且肌肉功能下降（P≤0.001）。大多数患者的颅颈角度高于正常值（ppp）：TMD组患者颅颈区域的生物力学、肌肉功能和残疾情况均发生了改变。

期刊介绍： CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians. CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest. CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
