目的：调查（1）无颈部疼痛或病理的受试者深颈屈肌（DNF）耐力测试的平均保持时间，以及（2）按年龄、性别和生活方式分类的不同受试者组是否显示不同的保持时间。设计：规范性研究。患者：126名成年人参与的便利样本。方法：采用组内相关系数评价4名治疗师的被试间信度。对每名受试者进行两次DNF耐力测试保持时间。结果：4名物理治疗师测量的DNF肌耐力的评价者间重复性信度系数为ICC（2，k）0.66（可信区间0.34-0.86）。男性的平均（SD）DNF耐力保持时间为38.9 ± 20.1秒，而女性为29.4 ± 13.7秒。2 × 2方差分析结果表明性别对DNF耐力有显著影响（F = 8.643; P = .004），而活动水平对DNF耐力无显著影响（F = 3.143; P = .079）。年龄和DNF耐力之间的相关性不显著（r = 0.11; P = 0.2）和活动水平和DNF耐力之间的相关性不显著（r = 0.156; P = 0.08）。结论：无症状男性比女性表现出更强的DNF耐力。受试者的DNF耐力之间的变异性很高。年龄在20 - 80岁之间和活动水平不影响DNF耐力。这是第一个可用于DNF耐力测试的规范性数据集，为在有颈痛病史的受试者中进行进一步研究奠定了基础，并帮助临床医生客观化患者DNF耐力缺陷的里程碑。PM R2011;3：105-110
Objective: To investigate (1) the average hold time for the deep neck flexors (DNF) endurance test in subjects without neck pain or pathology, and (2) whether different groups of subjects categorized by age, gender, and lifestyle display different hold times.Design: Normative research.Patients: A convenience sample of 126 adults participated.Methods: Intertester reliability of 4 therapists was evaluated by using intraclass correlation coefficients. The DNF endurance test hold time was conducted on each subject twice. The 2 hold-time scores were averaged and recorded.Results: Inter-rater reliability coefficient of reproducibility for DNF muscle endurance measured by 4 physical therapists was ICC (2,k) 0.66 (confidence interval, 0.34-0.86). The mean (SD) DNF endurance hold times for men was 38.9 +/- 20.1 seconds, whereas women was 29.4 +/- 13.7 seconds. Results of the 2 X 2 analysis of variance indicated that gender significantly influenced DNF endurance (F = 8.643; P = .004), whereas, the activity level did not (F = 3.143; P = .079). Correlations were not significant between age and DNF endurance (r = 0.11; P = .2) and between activity level and DNF endurance (r = 0.156; P = .08).Conclusions: Asymptomatic men displayed greater DNF endurance than women. The variability between subjects' DNF endurance capabilities was high. Age between 20 and 80 years and activity level did not affect DNF endurance. This is the first normative data set available for the DNF endurance test, which lays the foundation for further research in subjects with a history of cervicalgia and assists clinicians to objectify a milestone for DNF endurance deficits in patients.
