Peds SCD 的低系统/高局部运动负荷
儿童镰状细胞病的低全身/高局部运动负荷
研究概览
详细说明
概述:当前的试点研究是一项随机行为运动干预。
程序:
研究第一阶段:家庭 (n=60) 将完成基线研究访问。 然后,青少年将被随机分配到一组锻炼组,并在 UMMC 综合健康中心 (CIH) 亲自完成一节指导锻炼课程。 指导练习结束后,青少年将完成为期 3 天的家庭动态监测方案。 研究第二阶段:青少年将完成为期 8 周的远程医疗家庭锻炼方案。 青少年将在第 4 周和第 8 周完成为期 3 天的动态监测方案。青少年将在完成运动方案后一周内返回 UMMC CIH,以重复问卷调查和临床评估。 家长也会重复问卷。
研究第一阶段:
基线研究访问:注册后,RA 将获取家长联系信息和其他两个关系的联系信息。 青少年及其家长将使用 Apple iPad 上的 REDCap 电子数据收集来完成调查问卷(10 分钟)。 问卷将包括有关人口统计、疼痛、身体机能和负面情绪的项目(因为抑郁和负面情绪是 SCD11,63,112,113 青少年疼痛最有力的预测因素之一)。 抽血:将采集血样(10 分钟)用于测量基线炎症标记物。 将尽一切努力在预定的临床抽血期间收集血液并使用局部利多卡因乳膏。 临床和身体健康评估:接下来,Actigraph GT9X-BT 设备将被放置在青少年的手腕上,以在基线研究访问期间监测 HRV。 然后,青少年将完成临床和身体健康评估(30 分钟;详情如下)。
运动干预:随机化。 将使用 Microsoft Excel 2013 RANDBETWEEN1,2 函数以 2:1 的方式将 60 个号码随机分配到低系统力量训练组或中度系统运动组。 随机顺序将受到密码保护,并在教学练习之前解锁。 然而,值得注意的是,如果家庭表示他们没有安全的环境来完成中度全身运动干预(即没有安全的户外行走场所),那么青少年参与者将被分配到低系统力量训练团体。 下一个符合条件的参与者将被分配到适度的全身运动组以完成随机分组。 教学练习课程。 青少年将在 UMMC CIH 中心亲自进行一次 45 分钟的锻炼。 在开始锻炼之前,锻炼人员将对青少年和家长进行有关安全锻炼(例如,保持水分、适度锻炼水平)和潜在不良事件75(例如,疲劳、肌肉酸痛;有关更多详细信息,请参阅风险防护、锻炼课程)的教育。 运动前5分钟;将获得运动期间10、20、30和40分钟以及运动后5分钟的疼痛强度(主要结果)和HRV(次要结果)。 3 天动态监测。 教学练习结束后,青少年将参加连续 3 天的体动记录仪动态监测,并完成三天的疼痛日记。 活动记录仪像手表一样佩戴在非惯用手的手腕上,通过光和运动测量身体活动、睡眠和心率,并通过心率监测器测量心率变异性。 将收集每日日记疼痛强度和 24 小时体动记录仪得出的 HRV,并有助于实现目标 1:假设 1a 和 1b。 为了减轻参与者的负担,腕戴式体动记录仪将通过标准邮件装在软垫信封中退回。10
研究第二阶段:
8 周远程医疗锻炼方案。 采用受试者内和受试者间设计,青少年将作为自己的对照(事前事后),并完成为期 8 周(每周 3 次;每次 45 分钟)的 (1) 低系统力量训练或 ( 2)适度的全身运动训练。 指导练习课程结束后,所有练习课程将在家中完成,并由学习练习人员通过远程医疗进行监督。 每次锻炼期间,家长也必须在场。 如果家长不在场,锻炼时间将重新安排。 锻炼人员将记录每次训练中的锻炼不良事件。 所有不良事件将立即报告给医疗主管和 PI。
3 天动态监测。 在远程医疗锻炼方案的第 4 周和第 8 周,青少年将参加连续 3 天的每日日记和体动记录仪动态监测。 腕戴式体动记录仪将通过标准邮件装在软垫信封中和/或在后续就诊时退回。
后续访问。 家庭将在完成为期 8 周的远程医疗锻炼方案后 1 周内返回 UMMC CIH。 青少年将重复有关疼痛(主要结果,目标 2)和 HRV 和身体健康评估(次要结果,目标 2)的调查问卷。 家长也会重复问卷。

参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的:低系统力量训练
为期 8 周(每周 3 次;每次 45 分钟)的家庭远程医疗强化锻炼计划
|
全身力量训练低。
青少年将完成45分钟的运动训练。
将进行八项特定练习,以针对所有主要肌肉群:小腿抬高、握力、深蹲、坐姿划船、推胸、平板支撑、低背伸展和仰卧起坐(表 1)。
每次练习都涉及中等负荷的收缩,但持续时间最长可达五分钟。16,17
在每次锻炼期间,青少年将有 5 分钟的热身时间、5 分钟的放松时间,并可根据需要进行休息(至少 30 秒)。
青少年最初会通过减少休息时间然后增加负荷来进步。
我们将为青少年提供 2 磅重的健身球、阻力带、Thera Putty 和用于家庭锻炼的瑜伽垫。
年轻人会保留这种家庭健身器材。
|
|
实验性的:适度的全身运动
为期 8 周(每周 3 次;每次 45 分钟)的家庭远程医疗步行方案
|
分配到中等全身运动负荷组的青少年将以心率储备 (HRR) 的 40-59% 进行全身有氧运动 45 分钟。76,111
青少年将通过快步行走并边走边摆动手臂来完成适度的全身有氧运动。
锻炼人员将通过视频会议监督 5 分钟热身和 5 分钟放松,并在步行锻炼期间始终与青少年保持通话。
青少年将锻炼直到达到规定的持续时间或直到疲劳为止,此时他们会降低强度或停止直到恢复。
所有训练强度都将基于 HRR,因此是个性化的(不超过 HRR 的 59%)。
无法满足初始训练要求的青少年将在8周内缓慢进步。

将从青少年的电子健康记录中提取以下变量:出生日期、诊断、处方药物、并发症、过去一年的血液实验室结果、最后一次就诊时的身高和体重、以及期间急诊室就诊和因疼痛住院的次数过去三年。
并发症和疼痛相关的就诊/住院将决定 SCD 疾病的严重程度。
这项研究的一个潜在问题是 12-17 岁的广泛年龄范围,儿童不断变化的免疫系统和青春期坦纳阶段的差异可能会影响他们对运动的生理反应。
因此,年龄和估计的青春期坦纳阶段将作为可能的协变量进行检查。
儿科血液科医生/执业护士将在定期就诊时根据坦纳阶段标准评估青春期状态。
所有从业人员都接受过适当的儿科检查培训。
