急慢性颞下颌关节紊乱病患者临床疼痛特征对比研究

目的:探讨急、慢性颞下颌关节紊乱病(TMD)患者的临床疼痛特征。方法:纳入TMD患者68例(急性30例,慢性38例),使用视觉模拟量表评价患者的疼痛强度,短式McGill疼痛调查表评价患者的疼痛感觉和感受。结果:①静止和功能状态下急、慢性组组内男女患者之间疼痛强度的差异无统计学意义(P>0.05);②静止状态下急、慢性组患者疼痛强度的差异无统计学意义(P>0.05);③功能状态下女性患者急性组疼痛强度高于慢性组(P<0.05);④急性组患者常用胀痛、触痛、刺痛、持续固定痛来描述疼痛,慢性组患者常用的词汇是胀痛、痉挛牵扯痛、绞痛、持续固定痛;⑤急性组患者有15人(占50.00%)在情感项主要选择害怕和软弱无力,慢性组患者有29人(占76.32%)在情感项主要选择厌烦和软弱无力。结论:急、慢性TMD患者疼痛强度多为轻度和中度;急、慢性TMD患者对疼痛的感觉和感受有所不同。

Comparative study on the clinical pain features between acute and chronic temporomandibular disorders in TMD patients

Objective: To compare the clinical pain features between the patients with acute and chronic temporomandibular disorders(TMD).Methods: 30 patients with acute TMD and 38 with chronic were included in group acute and chronic respectively.Visual analog scale(VAS) and short-form mcgill pain questionnaire(SF-MPQ) were administered to assess the intensity,sensation and affection of the pain.Results: There was no statistical difference in the VAS scores between males and females or between acute and chronic TMD patients at rest(P>0.05).In the females,acute group had a higher VAS score than chronic group during function(P<0.05).Acute TMD patients often used "swelling pain","tenderness","tingle" and "continuous pain" to describe their pain,while the chronic ones prefered "swelling pain","spasm","colic pain","continuous pain" more.15 patients with acute TMD felt afraid and weak,while 29 patients with chronic TMD felt irritating and weak.Conclusion: Pain intensity in acute and chronic TMD patients is generally slight to moderate,sensation and affection of chronic TMD patients are different from acute ones.
