The authors conducted a study to compare the frequency of specific temporomandibular disorder (TMD) diagnoses in patients who had late whiplash syndrome (LWS) with that in a control group.
The authors recruited 65 patients who had orofacial pain and a previous diagnosis of LWS and 65 age- and sex-matched control patients who had chronic orofacial pain without a history of whiplash injury (WI) for a case-control series study. All patients completed a questionnaire pertaining to the Research Diagnostic Criteria for Temporomandibular Disorders and underwent a clinical examination.
The authors compared the frequency of TMD diagnoses in case patients with that in control patients by using a χ(2) test; they set the α level a priori at .05. The number of patients diagnosed with myofascial pain (MP) and disk displacement with reduction (DDWR) was significantly higher in the case group than in the control group (P = .002 and P = .001, respectively).
The results of this study show a higher frequency of MP and DDWR in patients with LWS than in patients with chronic orofacial pain and no history of WI. Practical Implications. Clinicians should be knowledgeable about the correlation between WI and TMD so they can inform and treat patients accurately.
作者进行了一项研究，比较了患有迟发性颈痛综合征（LWS）的患者与对照组患者中特定颞下颌关节紊乱（TMD）诊断的频率。
作者招募了 65 名患有口腔颌面部疼痛且先前被诊断为 LWS 的患者和 65 名年龄和性别匹配的患有慢性口腔颌面部疼痛且无颈挥鞭伤（WI）病史的对照组患者，进行了一项病例对照系列研究。所有患者均完成了一份与颞下颌关节紊乱研究诊断标准相关的问卷，并接受了临床检查。
作者使用卡方检验比较了病例组和对照组患者的 TMD 诊断频率；他们预先设定 α 水平为.05。患有肌筋膜疼痛（MP）和可复性盘前移位（DDWR）的患者数量在病例组中明显高于对照组（P=.002 和 P=.001）。
本研究结果表明，LWS 患者的 MP 和 DDWR 频率高于慢性口腔颌面部疼痛且无 WI 病史的患者。临床意义。临床医生应该了解 WI 和 TMD 之间的相关性，以便能够准确地为患者提供信息和治疗。
