Abstract

Background

Balance disorders are considered a serious diagnostic challenge, with many potential causes. The influence of temporomandibular disorders (TMD) on postural balance has numerous anatomical, biomechanical, physiological and functional argumentation, however, cohort studies on this subject do not give unambiguous results. It is suggested that only some forms of TMD may affect the body balance. Research question: Will body balance parameters differ in patients with particular subtypes of temporomandibular disorders and without temporomandibular disorders? Methods: cohort study. A total of 25 participants with TMD (9 with myofascial subtype; 9 with disc disorders subtype; 7 with mixed diagnosis) and 11 participants without TMD (control group) diagnosed by Research Diagnostic Criteria for TMD were assessed for body balance changes using force platform FreeMED MAXI ground reaction force platform (Sensor Medica; Guidonia Montecelio, Roma, Italia) under different mandibular conditions (rest position, clenching, clenching on cotton rolls). For the statistical analysis, the postural sway area of the Center of Pressure (COP) and its velocity were used. Results: The greatest differences in the sway area of the COP and its velocity were noticed when comparing the control group and the group with myofascial disorders. Statistically significant differences regarding the sways of COP in different mandible conditions were also shown by intragroup analyses in the group with myofascial and mixed forms. Both the results of the intra- and intra-group analyses shows that the involvement of the muscular factor may determine the occurrence of deviations in the body balance. Significance: The results of the project may extend the diagnosis of patients with balance disorders to the diagnosis of the masticatory system to accurately determine the source of the patient's problem.

各种亚型颞下颌关节紊乱对身体平衡的影响--初步研究

背景平衡失调被认为是一个严重的诊断难题，其潜在原因很多。颞下颌关节紊乱症（TMD）对姿势平衡的影响在解剖学、生物力学、生理学和功能学方面都有许多论据，但有关这一主题的队列研究并没有给出明确的结果。有人认为，只有某些形式的 TMD 可能会影响身体平衡。研究问题有特定亚型颞下颌关节紊乱症和无颞下颌关节紊乱症的患者的身体平衡参数是否会有所不同？方法：队列研究。根据 TMD 研究诊断标准确诊的 25 名 TMD 患者（9 名肌筋膜亚型患者；9 名椎间盘紊乱亚型患者；7 名混合诊断患者）和 11 名无 TMD 患者（对照组）在不同的下颌条件下（静止姿势、紧握、紧握棉卷），使用力平台 FreeMED MAXI 地面反作用力平台（Sensor Medica; Guidonia Montecelio, Roma, Italia）评估身体平衡的变化。统计分析使用了压力中心（COP）的姿势摇摆面积及其速度。结果显示对照组和肌筋膜障碍组在 COP 的摇摆面积和速度方面的差异最大。通过对肌筋膜疾病组和混合型疾病组的组内分析，不同下颌条件下 COP 摇摆的差异也具有统计学意义。组内和组内分析的结果都表明，肌肉因素的参与可能会决定身体平衡偏差的发生。意义重大：该项目的结果可将平衡失调患者的诊断扩展到咀嚼系统的诊断，从而准确确定患者问题的根源。

期刊介绍： Gait & Posture is a vehicle for the publication of up-to-date basic and clinical research on all aspects of locomotion and balance. The topics covered include: Techniques for the measurement of gait and posture, and the standardization of results presentation; Studies of normal and pathological gait; Treatment of gait and postural abnormalities; Biomechanical and theoretical approaches to gait and posture; Mathematical models of joint and muscle mechanics; Neurological and musculoskeletal function in gait and posture; The evolution of upright posture and bipedal locomotion; Adaptations of carrying loads, walking on uneven surfaces, climbing stairs etc; spinal biomechanics only if they are directly related to gait and/or posture and are of general interest to our readers; The effect of aging and development on gait and posture; Psychological and cultural aspects of gait; Patient education.
