The 10-meter Walking Test (10MWT) is often used to assess people with, e.g., stroke, but often using different procedures. The aims of this study were to translate the 10MWT into Danish, to determine the number of trials needed to achieve performance stability, and to examine the interrater reliability and agreement of the 10MWT in people with neurological disorders.
Translation followed international recommendations, and evaluated in a consecutive sample of 50 people with a neurological disorder. All participants performed 5 timed 10MWT trials (usual speed) with 20-seconds rest intervals between trials, supervised by a physical therapist. A second session was conducted with another physical therapist, separated with a mean (SD) of 2.7 (0.9) hours. The order of raters was randomized and they were blinded to each other's ratings. Repeated measures ANOVA determined performance stability, while ICC1.1, standard error of measurement (SEM), and minimal detectable change (MDC95) determined reproducibility.
Participant's improved their 10MWT scores significantly between the first and second trial only. The faster of the 2 trials took a mean of 11.95 (5.40) seconds, and significantly (P < 0.001) faster than the slowest; mean of 12.80 (6.13) seconds. The intraclass correlation coefficient (ICC; 95% confidence interval), SEM, and MDC, based on the fastest of 2 trials, were 0.97 (0.95-0.98), 0.06 m/s, and 0.17 m/s, respectively, and with no systematic between rater's bias.
We suggest that the faster of 2 timed trials be recorded for the 10MWT in people with neurological disorders, as we found excellent interrater reliability and low measurement error using this score.
10米步行试验（10MWT）常用于评估例如中风患者，但使用的程序往往不同。本研究的目的是将10MWT翻译成丹麦语，确定实现性能稳定性所需的试验次数，并检验10MWT在神经系统疾病患者中的评分者间信度和一致性。
翻译遵循国际建议，并在50例神经系统疾病患者的连续样本中进行评估。所有参与者在物理治疗师的监督下进行5次定时10MWT试验（正常速度），试验间隔休息20秒。由另一名物理治疗师进行第二次测试，两次测试之间的平均（标准差）间隔时间为2.7（0.9）小时。评分者的顺序是随机的，他们对彼此的评分不知情。重复测量方差分析确定性能稳定性，而组内相关系数（ICC1.1）、测量标准误差（SEM）和最小可检测变化（MDC95）确定再现性。
仅在第一次和第二次试验之间，参与者的10MWT分数有显著提高。两次试验中较快的一次平均用时11.95（5.40）秒，明显（P<0.001）快于最慢的一次；最慢一次的平均用时为12.80（6.13）秒。基于两次试验中较快一次的组内相关系数（ICC；95%置信区间）、SEM和MDC分别为0.97（0.95 - 0.98）、0.06 m/s和0.17 m/s，且评分者之间无系统偏差。
我们建议记录神经系统疾病患者10MWT两次定时试验中较快的一次，因为我们发现使用该分数具有出色的评分者间信度和较低的测量误差。
