有几份报告表明，头部前方姿势与颞下颌关节紊乱和下颌骨生长受限有关，这可能是由于下颌骨后移所致。然而，很少有报告是在头朝前的姿势下检查髁突的位置。这项研究的目的是检验这样一种假设，即在头朝前的姿势下，髁状突向后移动。记录了15例健康成年男性下颌休息位自然头位和深思熟虑前头位的下颌关节位置和咀嚼肌、颞肌和二腹肌的肌电活动。深思熟虑的前头姿势下的髁突位置明显比自然头位下的位置后移。深思熟虑的头部姿势下，咬肌和二腹肌的活动略有增加。这些结果表明，在头朝前姿势的受试者中，髁突向后移动。
There are several reports suggesting that forward head posture is associated with temporomandibular disorders and restraint of mandibular growth, possibly due to mandibular displacement posteriorly. However, there have been few reports in which the condylar position was examined in forward head posture. The purpose of this study was to test the hypothesis that the condyle moves posteriorly in the forward head posture. The condylar position and electromyography from the masseter, temporal and digastric muscles were recorded on 15 healthy male adults at mandibular rest position in the natural head posture and deliberate forward head posture. The condylar position in the deliberate forward head posture was significantly more posterior than that in the natural head posture. The activity of the masseter and digastric muscles in the deliberate forward head posture was slightly increased. These results suggest that the condyle moves posteriorly in subjects with forward head posture.
