The aim of this study was to examine the validity and reliability of the Sitting Assessment Scale (SAS) in individuals with cerebral palsy (CP).
The study included 34 individuals with a diagnosis of spastic CP. Individuals were evaluated with the Gross Motor Function Classification System and the Manual Ability Classification System. SAS and Trunk Control Measurement Scale (TCMS) were applied to the participants. The intraclass correlation coefficient (ICC) was calculated to determine the intraobserver and interobserver reliability of the scale scored by three different physiotherapists at two different time intervals. Internal consistency was calculated with Cronbach's ⍺ coefficient. The fit between SAS and TCMS for criterion-dependent validity was evaluated using Pearson Correlation Analysis.
According to the GMFCS level, 79.41% of the children were mildly (Level I-II), 14.71% were moderately affected (level III), and 5.88% were severely affected (level IV). Intra > observer and interobserver reliability values of SAS were extremely high (ICC> 0.923, ICC > 0.930). It was observed that the internal consistency of SAS had high values (Cronbach ⍺ > 0.822, Cronbach ⍺ > 0.804). For the criterion-dependent reliability; positive medium correlations found between SAS with Total TCMS Static Sitting Balance (r = 0.579, p < 0.001), with TCMS Selective Movement Control (r = 0.597, p < 0.001), with TCMS Dynamic Reaching (r = 0.609, p < 0.001), and with TCMS Total (r = 0.619, p < 0.001).
SAS was found to have high validity and reliability in children with CP. In addition, the test-retest reliability of the scale was also high. SAS is a practical tool that can be used to assess sitting balance in children with CP.
本研究旨在检验坐位评估量表（SAS）在脑瘫（CP）患者中的有效性和可靠性。
本研究纳入了 34 名痉挛型 CP 患者。采用粗大运动功能分级系统（GMFCS）和手动能力分级系统（MACS）对患者进行评估。将 SAS 和躯干控制测量量表（TCMS）应用于参与者。采用组内相关系数（ICC）计算由 3 名不同物理治疗师在 2 个不同时间间隔内评分的量表的观察者内和观察者间可靠性。采用 Cronbach's ⍺系数计算内部一致性。采用 Pearson 相关分析评估 SAS 与 TCMS 的标准相关性。
根据 GMFCS 水平，79.41%的儿童为轻度（水平 I-II），14.71%为中度（水平 III），5.88%为重度（水平 IV）。SAS 的观察者内和观察者间可靠性值极高（ICC>0.923，ICC>0.930）。SAS 的内部一致性具有较高的值（Cronbach ⍺>0.822，Cronbach ⍺>0.804）。对于标准相关性可靠性，SAS 与 TCMS 总静态坐位平衡（r=0.579，p<0.001）、TCMS 选择性运动控制（r=0.597，p<0.001）、TCMS 动态伸展（r=0.609，p<0.001）和 TCMS 总得分（r=0.619，p<0.001）之间呈正中等相关。
SAS 被发现具有在 CP 儿童中具有高有效性和可靠性。此外，该量表的重测信度也很高。SAS 是一种实用的工具，可用于评估 CP 儿童的坐位平衡。
