This research was composed of two studies of the neck muscle function and the mandibular position in the positions of forward and natural head postures.1) EMG study on the neck muscle: Objectives: Purpose of this study is to investigate the neck muscle function with EMG in the groups of forward and natural head postures. Materials and methods: Five male subjects with forward head posture and 7 male subjects with natural head posture from university dental students were used in this study. The EMG of sternocleidomastoid, sternohyoid, trapezius, digastric, masseter and temporal muscles were measured in both the forward head and natural head postures. Results: The sternocleidomastoid muscle activities in position of both forward and natural head posture were significantly greater in the group of forward head posture than in the group of natural head posture. The trapezius muscle activity in position of forced forward head posture was significantly smaller in the group of forward head post … More ure than in the group of natural head posture. Sternohyoid, digastric, masseter and temporal muscles activities were no significant difference between the both groups. Conclusion: Overloading the sternocleidomastoid muscle was suggested in the group of forward head posture. The symptoms of sternocleidomastoid muscle have been well reported in the patients of temporomandibular dysfunction with the muscle pain of the neck region. It has been suggested that the forward head posture is one of the factor of the TMD with the muscle pain of the neck region.2) Mandibular position study: Objectives: Purpose of this study is to investigate the mandibular position in the positions of forward and rotating head postures. Materials and methods: Fifteen adult male subjects without TMD, malocclusion and missing teeth were used in this study. The mandibular positions were measured in the positions of forward and natural head posture and 60 degrees rotating head on the sitting position using the mandibular movement analyzing system. Results: The mandible moved to right back upward position with slightly rotating in the position of forward head posture and moved to backward position of the rotating side while lower incisor point moved to opposite side in the head rotation. Conclusion: In the position of forward or rotate head, the soft tissue around neck and face region was stretched which moved the mandible to backward rotation and retro-position. Less

本研究包括两项研究：1）颈肌肌电研究：目的：本研究的目的是通过颈肌肌电研究，探讨颈肌在头前倾和自然位时的功能状态。材料与方法：研究对象为5名男性受试者，头部前倾，7名男性受试者，头部自然。在头前倾和自然头位下，测量胸锁乳突肌、胸骨舌骨肌、阔肌、二腹肌、咬肌和颞肌的肌电。结果如下：头前倾位和自然头位胸锁乳突肌活动均显著高于自然头位。头柱前移组在强迫性头前倾位时的肌电活动显著小于头柱前移组 ...更多信息 比自然头姿势组更自然。两组胸骨舌骨肌、二腹肌、咬肌和颞肌活动无显著性差异。结论：头前倾位时胸锁乳突肌负荷过重。摘要胸锁乳突肌的症状在颞下颌关节功能障碍合并颈部肌肉疼痛的病例中已有相当多的报道。研究结果表明，头前倾位是导致TMD患者颈部肌肉疼痛的重要因素之一。2）下颌位置研究：目的：研究头前倾位和头旋转位时的下颌位置。材料与方法：15名无TMD、错牙合、缺牙的成年男性受试者。利用下颌运动分析系统测量了受试者在头向前自然位和坐位旋转60 °时的下颌位置。结果如下：头前位时下颌骨向右后上方移动，并伴有轻微旋转，头旋转时下颌骨向旋转侧后方移动，下切牙点向对侧移动。结论：在头向前或旋转位时，颈部和面部周围的软组织被拉伸，使下颌骨向后旋转和后移。少
