To test whether the Neck Disability Index (NDI) would indicate higher reported disability among people with neck pain, cervicogenic headache, and temporomandibular disorders (TMD) when compared to people with only neck pain or neck pain with cervicogenic headache.
A total of 62 participants were enrolled and categorized into one of three groups: (1) neck pain only; (2) neck pain and cervicogenic headache; and (3) neck pain, cervicogenic headache, and TMD. NDI scores, pain, cervical active range of motion (AROM), and maximum mouth opening (MMO) were recorded for each subject. NDI scores were compared between groups using the Kruskal-Wallis test, and associations between the NDI and pain, cervical AROM, and MMO were tested using Pearson correlations.
No statistical difference in NDI score was identified among the three groups (P = .08). NDI scores were not correlated with MMO (P = .17) or TMD pain (P = .16), but were correlated with cervical AROM (r = -0.635 to -0.311), cervicogenic headache intensity (r = 0.355; P = .004), and cervical pain ratings (r = 0.619; P < .001) across all participants.
Participants' perceived disabilities were not associated with TMD pain or MMO. The NDI does not seem adequate for assessing TMD symptoms.
测试颈痛、颈源性头痛和颞下颌关节紊乱病（TMD）患者的颈痛患者相比，颈痛患者或颈痛合并颈源性头痛患者的颈痛患者的报告残疾程度是否更高。
共纳入 62 名参与者，并将其分为三组：（1）仅颈痛；（2）颈痛和颈源性头痛；（3）颈痛、颈源性头痛和 TMD。为每位受试者记录颈痛指数（NDI）评分、疼痛、颈椎主动活动范围（AROM）和最大张口度（MMO）。使用 Kruskal-Wallis 检验比较三组之间的 NDI 评分差异，使用 Pearson 相关性检验评估 NDI 与疼痛、颈椎 AROM 和 MMO 之间的相关性。
三组之间的 NDI 评分无统计学差异（P =.08）。NDI 评分与 MMO 无相关性（P =.17）或 TMD 疼痛无相关性（P =.16），但与颈椎 AROM （r = -0.635 至 -0.311）、颈源性头痛强度（r = 0.355；P =.004）和颈椎疼痛评分（r = 0.619；P <.001）相关。
参与者的感知残疾与 TMD 疼痛或 MMO 无关。NDI 似乎不能充分评估 TMD 症状。
