: The purpose of this study was to examine the psychometric properties of the neck disability index (NDI) and numeric pain rating scale (NPRS) in patients with neck pain (NP) without concomitant upper extremity (UE) symptoms. : A secondary psychometric analysis of 107 patients with NP without UE symptoms. Test-retest reliability, construct validity, area under the curve (AUC), minimum detectable change (MDC), and minimum clinically important difference (MCID) were calculated.: The NDI exhibited excellent reliability (ICC = 0.88; [0.63 to 0.95]), while the NPRS exhibited moderate reliability (ICC = 0.67; [0.27 to 0.84]). The AUC for both the NDI (0.86; [0.79 to 0.93]) and NPRS (0.81 [0.73 to 0.90]) was acceptable. The MDC for the NDI was 6.9, and the MCID for the NDI was 5.5(Sn = 0.83; Sp = 0.79). For the NPRS, the MDC was 2.6, and the MCID was 1.5(Sn = 0.93; Sp = 0.64). : The threshold for MCID for the NDI and NPRS in patients without UE symptoms is lower (NDI = 5.5; NPRS = 1.5) than that of patients with UE/radicular symptoms (NDI = 8.5 points; NPRS = 2.2). Knowledge of these cut-scores in each presentation of NP is needed for successful research and clinical treatment. Additional outcomes may be warranted for patients with UE symptoms.
本研究旨在考察颈痛（NP）患者无伴上肢（UE）症状时颈痛残疾指数（NDI）和数字疼痛评分量表（NPRS）的心理测量特性。对 107 例无 UE 症状的 NP 患者进行二级心理测量分析。计算了重测信度、结构效度、曲线下面积（AUC）、最小可检测变化（MDC）和最小临床重要差异（MCID）。NDI 表现出极好的可靠性（ICC=0.88；[0.63 至 0.95]），而 NPRS 表现出中等可靠性（ICC=0.67；[0.27 至 0.84]）。NDI（AUC 为 0.86；[0.79 至 0.93]）和 NPRS（AUC 为 0.81 [0.73 至 0.90]）的 AUC 均为可接受。NDI 的 MDC 为 6.9，NDI 的 MCID 为 5.5（Sn=0.83；Sp=0.79）。对于 NPRS，MDC 为 2.6，MCID 为 1.5（Sn=0.93；Sp=0.64）。对于无 UE 症状的患者，NDI 和 NPRS 的 MCID 阈值较低（NDI=5.5；NPRS=1.5），而对于有 UE/神经根症状的患者，NDI 和 NPRS 的 MCID 阈值较高（NDI=8.5 分；NPRS=2.2）。成功的研究和临床治疗需要了解每个 NP 表现的这些界值。对于有 UE 症状的患者，可能需要其他结果。
