This study examined the role of stress in subjects having combined muscle and temporomandibular joint pain compared to subjects having only muscle pain or only joint pain. It was found that the combined pain (n = 39) and muscle pain (n = 24) groups had comparable levels of pain intensity and activity impairment. The combined pain group, however, had the lowest level of stress and was rated lower than the muscle group in clinicians ratings of psychological factors, stress and chronicity. The combined pain group and joint pain group (n = 28) were found to be comparable in terms of the clinician's ratings. This data does not support the concept of a progression of symptoms from muscle pain to combined muscle and joint pain that would be expected from a stress-induced muscle hyperactivity model of temporomandibular disorders.
本研究调查了与仅有肌肉疼痛或仅有关节疼痛的受试者相比，压力在合并肌肉和颞下颌关节疼痛的受试者中所起的作用。研究发现，合并疼痛组（n = 39）和肌肉疼痛组（n = 24）在疼痛强度和活动受限程度方面相当。然而，合并疼痛组的压力水平最低，在临床医生对心理因素、压力和慢性程度的评分中，其得分低于肌肉疼痛组。合并疼痛组和关节疼痛组（n = 28）在临床医生的评分方面相当。这些数据不支持颞下颌关节紊乱症的压力诱导肌肉活动亢进模型所预期的症状从肌肉疼痛发展为肌肉和关节合并疼痛的概念。
