To describe the walking performance and physical activity of children with cerebral palsy (CP) by Gross Motor Function Classification System (GMFCS) level, age, sex, and geographical location; and, to examine the concurrent validity of the 4-item Early Activity Scale for Endurance (EASE) to walking performance and physical activity scores.
Seventy-nine children with CP participated. Parents completed the 4-item EASE. All children wore an Actigraph monitor ( = 79), and children in GMFCS levels I - III also wore a StepWatch monitor ( = 50), for seven days.
Only GMFCS level yielded significant differences in average strides taken per day, in strides per day taken faster than 30 strides per minute, in average physical activity counts per minute, and in minutes per day spent in moderate to vigorous physical activity. The 4-item EASE findings were moderately correlated with average physical activity counts per minute (.61, < .001) and minutes per day spent in moderate to vigorous physical activity (.62, < .001).
GMFCS level is predictive of both walking performance and physical activity in children with CP. The 4-item EASE may provide a quick and valid way to monitor physical activity in children with CP.
根据粗大运动功能分级系统（GMFCS）水平、年龄、性别和地理位置描述脑瘫儿童的行走表现和身体活动情况；并检验 4 项简易耐力活动量表（EASE）与行走表现和身体活动评分的同时效度。
79 名脑瘫儿童参与了研究。家长完成了 4 项 EASE 量表。所有儿童佩戴了 Actigraph 监测器（ = 79），GMFCS 水平为 I - III 的儿童还佩戴了 StepWatch 监测器（ = 50），监测时间为 7 天。
仅 GMFCS 水平在每日平均步幅、每日 30 步/分钟以上的步幅、平均每分钟身体活动计数和每日中高强度身体活动时间方面存在显著差异。4 项 EASE 量表的结果与平均每分钟身体活动计数（r=0.61，< 0.001）和每日中高强度身体活动时间（r=0.62，< 0.001）呈中度相关。
GMFCS 水平可预测脑瘫儿童的行走表现和身体活动。4 项 EASE 量表可能为监测脑瘫儿童的身体活动提供一种快速有效的方法。
