摘　　要：目的:探讨颞下颌关节(TMJ)疼痛患者感觉和运动功能的特征。方法:选择单侧TMJ疼痛患者与性别、年龄匹配的正常者各20名,测量并比较两组受试者的视觉模拟疼痛评分(VAS)、开口度(OR)、双侧TMJ的机械疼痛阈值(MPT)和压力疼痛阈值(PPT)。结果:病人组VAS值显著高于对照组(P<0.001),病人组开口度显著小于对照组(P<0.001)。患者TMJ疼痛侧MPT、PPT均小于对照组同侧(P<0.05)。病人组TMJ疼痛侧与无痛侧之间的MPT及PPT均存在统计学差异(P<0.05)。结论:TMJ疼痛患者对疼痛感觉较敏感,运动功能下降。Objective:To explore the difference of somatosensory and jaw function between patients with unilateral temporomandibular joint(TMJ)pain and normal subjects by quantitative sensory test and opening ranges.Methods:20 patients suffering from unilateral TMJ pain and 20 healthy controls were enrolled in this study.Visual analogue scale(VAS),opening ranges(OR)and mechanical pain threshold(MPT),pressure pain threshold(PPT)on both TMJ were measured and compared.Results:VAS of patients were higher than that of controls(P<0.001),but opening ranges were all smaller than controls(P<0.001).Both MPTs and PPTs of pain side of the patients were lower than ipilateral side of controls(P<0.05).MPTs and PPTs were also lower in pain side than those in contralateral side of TMJ in patients(P<0.05).Conclusions:TMJ pain patients demonstrated high sensitivity and limitation of jaw motion.
