ABSTRACT
Aims: To describe the development and evaluation of a novel task-based measure of powered mobility function: the Powered Mobility Function Scale (PMFS).
Methods: PMFS was developed in Hebrew in four phases, with feedback from clinicians and clients. Psychometric properties (inter-rater, test–retest reliability, concurrent, convergent and known-groups validity) were evaluated for N = 49 children and adolescents with Cerebral Palsy (11.1 ± 4.8y) using Powered Mobility Program (PMP), Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS) and Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT)
Results: PMFS development involved 3 versions over three years. Inter-rater reliability was =0.75–0.95 (video/observation). Test–retest reliability was =0.93–0.96. Concurrent validity (PMP) was =−0.84-to–0.96. Convergent validity (PEDI-CAT) was =−0.47-to-0.70. Known-groups validity (GMFCS/MACS) demonstrated medium effect sizes (r = 0.33–0.46)
Conclusions: PMFS is valid and reliable for measuring powered mobility function in children and adolescents with CP. Future validation of the English version of PMFS is warranted.

儿童和青少年脑瘫电动运动功能量表 (PMFS) 的开发和评估
摘要
目的:描述一种基于任务的新型动力移动功能测量的开发和评估:动力移动功能量表 (PMFS)。
方法:根据临床医生和客户的反馈,PMFS 是在希伯来语中分四个阶段开发的。使用动力活动计划 (PMP)、粗大运动功能评估了 N = 49 名脑瘫儿童和青少年 (11.1 ± 4.8 岁) 的心理测量特性(评分者间、重测信度、并发、收敛和已知组有效性)分类系统 (GMFCS)、手动能力分类系统 (MACS) 和残疾清单计算机自适应测试的儿科评估 (PEDI-CAT)
结果: PMFS 开发涉及三年内的 3 个版本。评分者间信度为=0.75–0.95(视频/观察)。重测信度为=0.93–0.96。同时效度 (PMP) 是=−0.84 到–0.96。收敛效度 (PEDI-CAT) 是=-0.47 到 0.70。已知组有效性 (GMFCS/MACS) 显示中等效果大小 (r = 0.33–0.46)
结论: PMFS 用于测量患有 CP 的儿童和青少年的动力移动功能是有效和可靠的。PMFS 英文版的未来验证是有保证的。
