Cerebral palsy (CP) is a lifelong disorder of posture and movement which often leads to a myriad of limitations in functional mobility. The Functional Mobility Scale (FMS) is a parent-report measure of functional mobility for children with CP at three different distances (5 m, 50 m, and 500 m). This is a cross-sectional study which sought to translate and culturally adapt the FMS into Arabic and to validate the translated version. Functional mobility for children and adolescents with CP in Saudi Arabia was examined.
The translation methodology complied with the World Health Organization Disability Assessment Schedule 2.0 translation package. A total of 154 children with CP were recruited (mean age 8.16 ± 3.32 years). Parents were interviewed to rate the usual walking ability of their children on the Arabic FMS. The re-test assessment was done with 34 families. The mean time interval between the first and second sessions was 14.3 days (SD = 8.5), with a range of 6-37 days.
Concurrent validity was explored using Spearman's rank correlation coefficient between scores of the Arabic FMS with their corresponding score on the Gross Motor Function Classification System (GMFCS). Spearman's values ranged between (-0.895 and 0.779), indicating strong to very strong correlations. The Test-retest reliability was examined using Cohen's weighted kappa, which showed almost perfect agreements. There was greater limitation for functional mobility at longer distances as 55.2% of children could not complete 500 meters (FMS score ). Overall, there was limited use of wheelchairs for all distances (ranging from 9.1% to 14.3%). Levels IV and V on the GMFCS had less variation in FMS scores and most of the children in these levels either did not complete the distances (no functional mobility at all distances) or used a wheelchair for mobility.
The Arabic FMS was shown to be a reliable and valid measure of functional mobility for children with CP in their environment based on the parental reports. Functional mobility varied at different distances and within each GMFCS level. The use of both the GMFCS and FMS when assessing children with CP is recommended.
脑瘫（CP）是一种终身姿势和运动障碍，通常会导致多种功能移动受限。功能移动量表（FMS）是一种针对 CP 儿童的家长报告式功能移动测量工具，包括三个不同距离（5 米、50 米和 500 米）。本研究为横断面研究，旨在将 FMS 翻译并文化适应为阿拉伯语版本，并对翻译后的版本进行验证。研究对象为在沙特阿拉伯的 CP 儿童和青少年的功能移动能力。
翻译方法遵循世界卫生组织残疾评估表 2.0 翻译包。共招募了 154 名 CP 儿童（平均年龄 8.16±3.32 岁）。家长接受访谈，对其子女的阿拉伯 FMS 通常步行能力进行评分。34 个家庭接受了复测评估。第一次和第二次评估之间的平均时间间隔为 14.3 天（SD=8.5），范围为 6-37 天。
使用阿拉伯 FMS 得分与粗大运动功能分类系统（GMFCS）得分之间的 Spearman 秩相关系数来探索同时效度。Spearman 值范围在-0.895 到 0.779 之间，表明存在强到非常强的相关性。使用 Cohen 的加权 kappa 检验测试-重测信度，显示出几乎完美的一致性。功能移动受限在较长距离更为明显，因为 55.2%的儿童无法完成 500 米（FMS 得分）。总体而言，所有距离的轮椅使用率都较低（范围为 9.1%至 14.3%）。GMFCS 等级 IV 和 V 的 FMS 评分变化较小，这些等级中的大多数儿童要么完全无法完成这些距离（所有距离都无功能移动），要么使用轮椅移动。
根据家长报告，阿拉伯 FMS 被证明是一种可靠且有效的 CP 儿童环境下功能移动能力测量工具。不同距离和每个 GMFCS 等级内的功能移动能力都有所不同。建议在评估 CP 儿童时同时使用 GMFCS 和 FMS。
