项目摘要
Epidemiological studies reveal a high comorbidity of pain in the maxillofacial area with pain in the neck and back which represent an extraordinary financial burden on the health care system. It is assumed that the listed symptoms are associated with the symptom complex of craniomandibular dysfunction (CMD). So far there is a low level of evidence for the neuromuscular interactions between the craniomandibular system (CMS) and other motor sub-segments of the human body.In our previous work, initial findings of the impact of the CMS on the neck muscles and the body posture in the habitual standing position are detected. The planned experimental randomized study will provide information about the effect of a controlled biting task on the dynamic balance and posture in healthy subjects during the performance of simple and complex motion tasks. For this purpose, a complex biomechanical motion analysis is performed. Besides the bite forces, kinematic, dynamic and electromyographic characteristics of the movements are recorded synchronously. The segment movements are captured with infrared cameras. Forceplates are used to measure ground reaction forces and the foot pressure. A telemetric 16-channel EMG device is used to measure the muscle activity of the lower extremities. Based on the processed kinematic data, the joint angle and joint torque curves and the center of gravity can be calculated by means of model calculation. For analysis of the static motion tasks, the position of the body´s center of gravity and the position of the center of pressure (COP) over the support base can be analyzed. For the dynamic movement tasks, the mathematical model of von Hof is used to determine the dynamic stability. To elucidate possible differences in the stability parameters between the conditions biting and not biting, the coordination of movements of the subjects are analyzed by using classical discrete parameter of isolated degrees of freedom. The coordination between different degrees of freedom is tested by means of continuous relative phase angle and the similarity of the phase angle by means of orthogonal reference functions.On the basis of the data and results, a deeper neurobiological understanding of the complex interaction of musculoskeletal sub-segments should help to reveal possible functional and pathophysiological interaction between the CMS and the human musculoskeletal system. This knowledge may help to develop optimized, cost-cutting treatment strategies.
流行病学研究表明,颌面部疼痛与颈部和背部疼痛的共病率很高,这对医疗保健系统造成了巨大的经济负担。假设列出的症状与颅下颌功能障碍(CMD)的综合症状相关。颅下颌系统(craniomandibular system,CMS)与人体其他运动亚段之间的神经肌肉相互作用的证据很少,我们在以往的工作中,初步发现了CMS对颈部肌肉和习惯站立位时身体姿势的影响。计划的实验性随机研究将提供关于在执行简单和复杂运动任务期间,受控咬合任务对健康受试者动态平衡和姿势的影响的信息。为此,进行复杂的生物力学运动分析。除了咬合力,运动学,动力学和肌电特征的运动同步记录。用红外摄像机捕捉片段运动。测力板用于测量地面反作用力和足部压力。遥测16通道EMG设备用于测量下肢的肌肉活动。基于处理后的运动学数据,通过模型计算,可以计算出关节角和关节力矩曲线以及重心。对于静态运动任务的分析,可以分析身体重心的位置和支撑底座上方的压力中心(COP)的位置。对于动态运动任务,采用冯霍夫数学模型确定动态稳定性。为了阐明咬和不咬的条件之间的稳定性参数可能存在的差异,通过使用孤立的自由度的经典离散参数分析了受试者的运动协调。不同自由度之间的协调是通过连续的相对相位角和相位角的相似性,通过正交参考functions.On的数据和结果的基础上,一个更深层次的神经生物学理解的复杂的相互作用的肌肉骨骼亚段应有助于揭示可能的功能和病理生理之间的相互作用CMS和人类肌肉骨骼系统。这些知识可能有助于制定优化的、降低成本的治疗策略。
