Evaluate the validity of the Kids-Balance Evaluation Systems Test (Kids-BESTest) clinical criteria for the Functional Reach Test (FRT) forward and lateral with laboratory measures of postural control in children with cerebral palsy (CP).
Psychometric study of face, concurrent, and content validity.
Clinical laboratory.
Children (N=58) aged 7-18 years (ambulant CP n=17, typically developing [TD] n=41).
Not applicable.
Stability limits in standing were assessed using the Kids-BESTest items for FRT forwards (FRT), FRT lateral preferred (FRT), and FRT lateral nonpreferred (FRT). Force platforms and kinematic markers were used to collect information on center of pressure (CoP) and joint movement during reach. Analyses included face validity (Kids-BESTest scores compared between CP and TD groups), concurrent validity (agreement between Kids-BESTest scores and digitally derived scores), and content validity (relations between Kids-BESTest scores with kinematic and CoP data).
Face validity of Kids-BESTest criteria was demonstrated with lower scores for CP compared to TD groups for FRT (P<.001) and FRT (P=.03) and equal scores for FRT (P=.12). For concurrent validity, agreement between Kids-BESTest scores and digitally derived scores was good to excellent for FRT (88%-100%) and good for FRT (86%-88%) for both groups. For content validity, the CP group Kids-BESTest scores were correlated with CoP-Range during FRT (ρ=0.68) and CoP-Range during FRT (ρ=0.57). For kinematic data, correlations were moderate-high between Kids-BESTest scores and range of hip flexion (ρ=0.51) and ankle plantar flexion (ρ=0.75) during FRT, and trunk lateral flexion (ρ=0.66) during FRT.
The FRT demonstrated face, concurrent, and content validity. The FRT demonstrated concurrent validity, but partial face and content validity. To improve validity of Kids-BESTest FRT criteria, additional descriptors have been added under the scoring criteria to enable clinicians to quantify observed reach strategies.
评估 Kids-Balance Evaluation Systems Test（Kids-BESTest）临床标准中针对脑瘫（CP）儿童功能性伸展测试（FRT）前后向和侧方的有效性，该标准结合了姿势控制的实验室测量值。
表面效度、同时效度和内容效度的心理测量学研究。
临床实验室。
年龄为 7-18 岁的儿童（能走动的 CP 组 n=17，典型发育组 n=41）。
不适用。
使用 Kids-BESTest 针对 FRT 向前（FRT）、FRT 侧方优先（FRT）和 FRT 侧方非优先（FRT）的项目评估站立时的稳定极限。力平台和运动学标记用于收集在伸展过程中有关中心压力（CoP）和关节运动的信息。分析包括表面效度（CP 组与 TD 组之间的 Kids-BESTest 评分比较）、同时效度（Kids-BESTest 评分与数字衍生评分之间的一致性）和内容效度（Kids-BESTest 评分与运动学和 CoP 数据之间的关系）。
Kids-BESTest 标准的表面效度得到了证明，CP 组的 FRT（P<.001）和 FRT（P=.03）得分低于 TD 组，而 FRT（P=.12）得分相等。对于同时效度，Kids-BESTest 评分与数字衍生评分之间的一致性对于两组的 FRT（88%-100%）和 FRT（86%-88%）均为良好至优秀。对于内容效度，CP 组的 Kids-BESTest 评分与 FRT 期间的 CoP 范围（ρ=0.68）和 FRT 期间的 CoP 范围（ρ=0.57）相关。对于运动学数据，Kids-BESTest 评分与 FRT 期间髋关节屈曲（ρ=0.51）和踝关节跖屈（ρ=0.75）以及 FRT 期间躯干侧向屈曲（ρ=0.66）之间的相关性为中高度。
FRT 表现出表面、同时和内容效度。FRT 表现出同时效度，但具有部分表面和内容效度。为了提高 Kids-BESTest FRT 标准的有效性，在评分标准下添加了其他描述符，以使临床医生能够量化观察到的伸展策略。
