This study aimed to describe the 24-hour composition of movement behaviors, including sleep, sedentary behavior, and physical activity (PA), among pediatric sports-related concussion (SRC) patients over their recovery period, assess the association between movement compositions and recovery time, and understand feasibility of 24-hour accelerometry in the study population. A cohort of 50 pediatric SRC patients were asked to wear a wrist-worn accelerometer continuously for the duration of their recovery. Among all enrolled participants, the sample was primarily 14 or 15 years of age (65%), female (55%), and recovered in under 28 days (88%). Accelerometer compliance was moderate; 35 participants (70%) were compliant with the protocol. Compositional analysis was used to address time-use objectives in 33 participants who provided adequate data for inclusion. Overall, participants spent an average of 50% of their 24-hour day sedentary, 33% sleeping, 11% in light intensity PA, and 6% in moderate or vigorous intensity PA. The 24-hour composition of movement behaviors was not associated with recovery time ( = .09-.99). However, the limited sample size may have contributed to null findings. Given recent evidence supporting the effects of sedentary behavior and PA on concussion recovery, future studies should aim to further validate these findings in a larger sample.
本研究旨在描述儿科运动相关性脑震荡（SRC）患者在恢复期 24 小时的运动行为组成，包括睡眠、久坐行为和体力活动（PA），评估运动组成与恢复时间之间的关联，并了解在研究人群中使用 24 小时加速度计的可行性。招募了 50 名儿科 SRC 患者，要求他们在整个恢复期内连续佩戴腕戴式加速度计。在所有入组参与者中，样本主要为 14 或 15 岁（65%）、女性（55%），在 28 天内恢复（88%）。加速度计的依从性中等；35 名参与者（70%）符合协议。在提供了足够纳入数据的 33 名参与者中，使用构成分析来解决时间利用目标。总体而言，参与者在 24 小时中平均有 50%的时间处于久坐状态，33%的时间处于睡眠状态，11%的时间处于低强度 PA 状态，6%的时间处于中高强度 PA 状态。运动行为的 24 小时组成与恢复时间无关（ = .09-.99）。然而，样本量有限可能导致了无效的发现。鉴于最近有证据支持久坐行为和 PA 对脑震荡恢复的影响，未来的研究应旨在更大的样本中进一步验证这些发现。
