The present follow-up study in 20 women with TMJ pain and reduced mandibular function associated with disc derangement, osteoarthritis, or inflammatory disorders aimed at investigating whether pain reduction was reflected in function.
After 3 years and conventional therapy, 19 of the patients and 15 of the original 20 matched controls completed a questionnaire, including RDC/TMD Jaw Disability Scale and TMJ chewing pain (VAS). Fourteen patients also accepted reexamination comprising TMJ pressure-pain thresholds (PPT), jaw opening, bite force, and jaw kinematics during chewing.
VAS was significantly reduced in patients at the follow-up, but PPT was unchanged, and Jaw Disability ratings were significantly higher than in controls. However, the patients' jaw opening, chewing speed, and bite force had increased significantly.
With reduction of TMJ pain, function improved in patients to a level that approached reference levels, indicating a marked ability of the nervous system in restoring motor activity.
本随访研究针对20名患有颞下颌关节疼痛且下颌功能因盘状移位、骨关节炎或炎症性疾病而减退的女性,旨在调查疼痛减轻是否反映在功能上。
经过3年及常规治疗后,19名患者和最初20名匹配对照中的15名完成了一份问卷,包括RDC/TMD下颌残疾量表和颞下颌关节咀嚼疼痛(视觉模拟评分法)。14名患者还接受了复查,包括颞下颌关节压痛阈值(PPT)、张口度、咬合力以及咀嚼时的下颌运动学检查。
随访时患者的视觉模拟评分法评分显著降低,但压痛阈值未变,且下颌残疾评级显著高于对照组。然而,患者的张口度、咀嚼速度和咬合力显著增加。
随着颞下颌关节疼痛减轻,患者的功能得到改善,接近参考水平,表明神经系统在恢复运动活动方面具有显著能力。
