Adolescents and young adults with cerebral palsy (CP) show reduced motor function and gait efficiency, and lower levels of habitual physical activity (HPA), than adolescents with typical development and children with CP. This study examined activity duration and patterns in this population in the Middle East through long-term monitoring of a large sample using accelerometers.
Adolescents and young adults with bilateral CP at Gross Motor Function Classification System (GMFCS) levels II, III, and IV, were monitored in their habitual environment for four consecutive days with ActivPAL3 monitors. Time spent in sedentary, standing, and walking activities, and frequency of walking steps and transitions, were analysed for each GMFCS level.
Measurements were made on 222 participants (132 males, 90 females; mean age 16 y 9 mo SD 2y, range 13 y 4 mo-22 y). The Mann-Whitney U test demonstrated significant differences (p<0.05) between GMFCS levels, showing reduced walking and standing activity and increased sedentary duration at higher GMFCS levels (p<0.001), except for increased standing time between GMFCS levels II and III (p=0.07). Participants in educational facilities exhibited less sedentary behaviour than those who were homebound (p<0.05).
These descriptions of duration and frequency of active and sedentary behaviours may serve as a basis for recommendations to minimize inactivity in this population. Adolescents and young adults with CP in the Middle East demonstrate similar patterns of HPA to their peers in other regions.
与发育正常的青少年和脑瘫儿童相比，患有脑瘫（CP）的青少年和青年运动功能和步态效率降低，习惯性身体活动（HPA）水平较低。本研究通过使用加速度计对大量样本进行长期监测，考察了中东地区该人群的活动持续时间和模式。
使用ActivPAL3监测仪，在其日常环境中对粗大运动功能分类系统（GMFCS）II、III和IV级的双侧脑瘫青少年和青年进行连续四天的监测。分析了每个GMFCS级别在久坐、站立和行走活动中所花费的时间，以及行走步数和转换频率。
对222名参与者（132名男性，90名女性；平均年龄16岁9个月，标准差2岁，范围13岁4个月至22岁）进行了测量。曼-惠特尼U检验显示GMFCS级别之间存在显著差异（p<0.05），表明在较高的GMFCS级别中，行走和站立活动减少，久坐时间增加（p<0.001），GMFCS II级和III级之间站立时间增加除外（p=0.07）。在教育机构中的参与者比居家的参与者久坐行为更少（p<0.05）。
这些关于活跃和久坐行为的持续时间和频率的描述可为减少该人群不活动状态的建议提供依据。中东地区患有脑瘫的青少年和青年表现出与其他地区同龄人相似的HPA模式。
