Little is known about the measurement properties of clinical tests of stepping in different directions for children with cerebral palsy (CP) and Down syndrome (DS). The ability to step in various directions is an important balance skill for daily life. Standardized testing of this skill can yield important information for therapy planning. This observational methodological study was aimed at defining the relative and absolute reliability, minimal detectable difference, and concurrent validity with the Timed Up-&-Go (TUG) of the Four Square Step Test (FSST) for children with CP and DS. Thirty children, 16 with CP and 14 with DS, underwent repeat testing 2 weeks apart on the FSST by 3 raters. TUG was administered on the second test occasion. Intraclass correlation coefficients (ICC [1,1] and [3,1]) with 95% confidence intervals, standard error of measurement (SEM), minimal detectable difference (MDD) and the Spearman rank correlation coefficient were computed. The FSST demonstrated excellent interrater reliability (ICC=.79; 95% CI: .66, .89) and high positive correlation with the TUG (r=.74). Test-retest reliability estimates varied from moderate to excellent among the 3 raters (.54, .78 and .89 for raters 1, 2 and 3, respectively). SEM and MDD were calculated at 1.91s and 5.29s, respectively. Scores on the FSST of children with CP and DS between 5 and 12 years of age are reliable and valid.
对于脑瘫（CP）和唐氏综合征（DS）儿童向不同方向迈步的临床测试的测量特性，人们了解甚少。向各个方向迈步的能力是日常生活中一项重要的平衡技能。对这项技能进行标准化测试可为治疗计划提供重要信息。这项观察性方法学研究旨在确定四方步测试（FSST）对于CP和DS儿童的相对和绝对可靠性、最小可检测差异以及与计时起立行走测试（TUG）的同时效度。30名儿童，16名患有CP，14名患有DS，由3名评估者对其进行FSST测试，两次测试间隔2周。第二次测试时进行TUG测试。计算了组内相关系数（ICC [1,1]和[3,1]）及其95%置信区间、测量标准误差（SEM）、最小可检测差异（MDD）以及斯皮尔曼等级相关系数。FSST显示出极好的评估者间可靠性（ICC = 0.79；95% CI：0.66，0.89），并且与TUG呈高度正相关（r = 0.74）。3名评估者的重测可靠性估计值从中度到极好不等（评估者1、2和3分别为0.54、0.78和0.89）。SEM和MDD分别计算为1.91秒和5.29秒。5至12岁的CP和DS儿童在FSST上的得分是可靠且有效的。
