背景帕金森病是一种促进身体运动变化的神经系统疾病。目的 本研究的目的是探讨帕金森病患者与无症状对照者相比，在磨牙咬合力、肌电活动和颅颈肌厚度方面的口颌功能损害情况。方法 将 24 名受试者分为两组，帕金森病组（n = 12）和对照组（n = 12）。根据磨牙咬合力、肌电图活动（休息、左右侧向、前伸、最大随意收缩）以及左右颞部（前部）、咬肌和胸锁乳突肌的厚度（休息和最大随意收缩）对受试者进行评估。将结果提交给多变量方差分析 (MANOVA)，以比较两个独立组的平均值，并将帕金森病和颅颈肌肉的诊断作为自变量。对于事后比较，使用了 Bonferroni 校正（P < 0.05）。结果帕金森病组两侧最大磨牙咬合力平均值较低，下颌任务期间肌电活动显着增加，咬肌和胸锁乳突肌平均厚度值较低，颞肌（前部）平均厚度值较高。结论：帕金森病患者可能出现口颌系统功能改变，与咬合力、肌电活动和颅颈肌厚度有关。帕金森病患者颞肌厚度较大可能会影响他们的日常生活活动，尤其是咀嚼和营养方面。
Background Parkinson's disease is a neurological disorder that promotes motor changes in the body. Objective The aim of this study was to investigate the impairment of the stomatognathic function regarding molar bite force, electromyographic activity and thickness of the craniocervical muscles in patients with Parkinson's disease in comparison with those in asymptomatic controls. Methods Twenty-four subjects were divided into two groups, a Parkinson's disease group (n = 12) and a control group (n = 12). The subjects were evaluated on the basis of molar bite force, electromyographic activity (rest, right and left laterality, protrusion, maximum voluntary contraction) and thickness (rest and maximum voluntary contraction) of the right and left temporal (anterior portion), masseter and sternocleidomastoid muscles. The results were submitted to a multivariate analysis of variance (MANOVA) to compare the means of the two independent groups, considering diagnosis of Parkinson's disease and craniocervical muscles as independent variables. For the post hoc comparisons, Bonferroni correction was used (P < 0.05). Results Parkinson's disease group presented lower mean values both sides for maximal molar bite force, significant increases in the electromyographic activities during mandibular tasks, lower mean thickness values of the masseter and sternocleidomastoid muscles, and higher mean thickness values of the temporalis muscles (anterior portion). Conclusion The results suggest that patients with Parkinson's disease may present functional changes of the stomatognathic system, related to bite force, electromyographic activity and thickness of the craniocervical muscles. The greater temporal muscle thickness in Parkinson's disease patients may compromise their daily life activities, especially with respect to chewing and nutrition.
