To assess the influence of different concurrent cognitive tasks on gait characteristics in children with cerebral palsy (CP) and typically developed (TD) controls.
Eleven children with CP and eleven TD controls walked under three conditions: at a self-selected speed, at a self-selected speed while memorizing and recalling a series of three random numbers, at a self-selected speed while listening and identifying commonly experienced sounds. Gait parameters were measured with the GAITRite(®) system.
Children with CP walked slower in both assignments as compared to baseline walking; TD controls reduce walking velocity only during the sounds assignment. Step length was constantly reduced and step time and length variability were constantly increased among children with CP as compared to TD controls, throughout assignments.
It might be advisable for clinicians when assessing walking performance in children with CP, to assess it during both single and dual-task conditions.
评估不同的并发认知任务对脑瘫（CP）儿童及正常发育（TD）对照儿童步态特征的影响。
11名脑瘫儿童和11名正常发育对照儿童在三种条件下行走：自选速度行走、自选速度行走同时记忆和回忆一系列三个随机数字、自选速度行走同时聆听并识别常见声音。使用GAITRite（®）系统测量步态参数。
与基线行走相比，脑瘫儿童在两项任务中的行走速度均较慢；正常发育对照儿童仅在声音任务期间行走速度降低。与正常发育对照儿童相比，在整个任务过程中，脑瘫儿童的步长持续缩短，步时间和步长变异性持续增加。
临床医生在评估脑瘫儿童的行走表现时，在单任务和双任务条件下进行评估可能是明智的。
