Physical activity undertaken by stroke survivors is generally low. This trial investigated the feasibility of delivering a high-intensity treadmill and self-management program to people with stroke undergoing inpatient rehabilitation and determine whether physical activity, walking ability and cardiorespiratory fitness could be increased.
A phase I, single-group, pre-post intervention study was conducted with stroke survivors undergoing inpatient rehabilitation who could walk. Participants undertook a high-intensity treadmill and self-management program for up to 30 min, three times a week for 8 weeks under the supervision of their usual physiotherapist. Feasibility was determined by examining compliance, satisfaction and adverse events. Clinical outcomes were amount of physical activity, walking ability, and cardiorespiratory fitness collected pre-training (week 0), post-training (week 8), and at follow-up (week 26).
Forty stroke survivors participated, completing 10 (SD 6) sessions, 94% at the specified training intensity, with high satisfaction and no adverse events related to the intervention. At week 8, participants completed 2749 steps/day (95% CI 933 to 4564) more physical activity than at week 0. Walking distance increased by 110 m (95% CI 23 to 196), walking speed by 0.24 m/s (95% CI 0.05 to 0.42), and VO2 peak by 0.29 ml/kg/min (95% CI 0.03 to 0.56). At week 26, increases in physical activity, walking distance and speed, and cardiorespiratory fitness were maintained.
A high-intensity treadmill training program embedded within a self-management approach during inpatient rehabilitation appears feasible and potentially may offer sustained improvements in physical activity, walking ability, fitness, and quality of life. A randomised trial is warranted.
This feasibility study was registered with the Australian New Zealand Clinical Trials Registry ( ACTRN12613000764730 ).
中风幸存者的身体活动水平普遍较低。本试验调查了为正在接受住院康复治疗的中风患者提供高强度跑步机和自我管理计划的可行性，并确定是否可以提高身体活动、步行能力和心肺适能。
对能够行走的住院康复中风幸存者进行了一项I期单组干预前后研究。参与者在其常规物理治疗师的监督下，进行为期8周、每周三次、每次长达30分钟的高强度跑步机和自我管理计划。通过检查依从性、满意度和不良事件来确定可行性。临床结果包括训练前（第0周）、训练后（第8周）和随访（第26周）收集的身体活动量、步行能力和心肺适能。
40名中风幸存者参与，完成了10（标准差6）次训练，94%达到规定训练强度，满意度高，且无与干预相关的不良事件。在第8周时，参与者每天的身体活动量比第0周多完成2749步（95%可信区间933至4564）。步行距离增加了110米（95%可信区间23至196），步行速度提高了0.24米/秒（95%可信区间0.05至0.42），最大摄氧量提高了0.29毫升/千克/分钟（95%可信区间0.03至0.56）。在第26周时，身体活动、步行距离和速度以及心肺适能的增加得以维持。
在住院康复期间采用自我管理方法的高强度跑步机训练计划似乎是可行的，并且可能会持续改善身体活动、步行能力、适能和生活质量。有必要进行一项随机试验。
本可行性研究已在澳大利亚新西兰临床试验注册中心注册（ACTRN12613000764730）。
