Abstract：
UNASSIGNED: Proprioceptive neuromuscular facilitation (PNF) stretching exercises have been widely advocated for the management of patients with different musculoskeletal conditions. However, its effect on the treatment of temporomandibular dysfunction (TMD) in patients with forward head posture (FHP) has not been fully investigated.
UNASSIGNED: To investigate the effect of PNF stretching exercises on the treatment of TMD in patients with FHP.
UNASSIGNED: A prospective, randomized, double-blinded clinical trial. Twenty-four patients with TMD and FHP aged from 18-40 years were randomly assigned to PNF or control group. The PNF group composed of 12 patients received PNF stretching exercises of masticatory muscles in addition to routine physical therapy treatment (FHP correction exercises and ultrasound for the temporomandibular joint); the control group composed of 12 patients received routine physical therapy treatment only. Interventions were conducted twice a week for six weeks. Craniovertebral angle, pain threshold, pain intensity, temporomandibular joint ROM, and temporomandibular joint function were assessed for all participants before and after the intervention. The outcomes were analyzed using Two-way mixed MANOVA. For further multiple comparisons, post-hoc tests with the Bonferroni correction were performed.
UNASSIGNED: There was no significant difference between both groups pre-treatment (p> 0.05). Comparison between groups post-treatment revealed statistically significant differences in all outcome measures (p< 0.05) in favor of the PNF group.
UNASSIGNED: Adding PNF stretching exercises of masticatory muscles to routine physical therapy programs is an effective method for management of TMD in patients with FHP more than routine physical therapy programs alone.

摘要：
■本体感受神经肌肉促进（PNF）伸展运动已被广泛提倡用于治疗患有不同肌肉骨骼疾病的患者。然而,它对前头位（FHP）患者颞下颌关节功能障碍（TMD）的治疗效果尚未得到充分研究。
■探讨PNF伸展运动对FHP患者TMD治疗的影响。
■预期，随机化，双盲临床试验。将24例年龄在18-40岁的TMD和FHP患者随机分为PNF组或对照组。由12例患者组成的PNF组除了常规物理疗法治疗（FHP矫正练习和颞下颌关节超声检查）外，还接受了咀嚼肌的PNF伸展运动；由12例患者组成的对照组仅接受常规物理疗法治疗。每周进行两次干预，持续六周。头颅角度，痛阈值,疼痛强度，颞下颌关节ROM，在干预前后对所有参与者进行颞下颌关节功能评估。使用双向混合MANOVA分析结果。对于进一步的多重比较，使用Bonferroni校正进行事后测试。
■两组治疗前无显著差异(p>0.05)。治疗后组间比较显示，所有结果指标的统计学差异（p<0.05）有利于PNF组。
■在常规物理治疗计划中添加咀嚼肌的PNF伸展运动是治疗FHP患者TMD的有效方法，而不仅仅是常规物理治疗计划。
■探讨PNF伸展运动对FHP患者TMD治疗的影响。
