[Purpose] This study aimed to assess the known-groups validity of the estimated metabolic equivalents during physical activities using accelerometer, Active Style Pro HJA 350-IT, in people with subacute stroke. [Subjects and Methods] Ten participants with subacute stroke and ten healthy people performed six activities (lying, sitting, standing, sitting with reaching task, standing with reaching task, and walking) and metabolic equivalents were estimated using the accelerometer during each activity. These estimated metabolic equivalents were compared with reported metabolic equivalents through compendiums or previous studies. Additionally, the estimated metabolic equivalents were compared between subacute stroke and healthy control participants. [Results] The estimated metabolic equivalents of both groups during maintaining posture showed significantly lower values in comparison with previous studies. There were no significant differences between the estimated metabolic equivalents during sitting with reaching tasks or standing with reaching tasks when compared with compendium metabolic equivalents across both groups. The estimated metabolic equivalents during walking were inevitable values significantly differed from previous study which conducted with stroke patients with lower gait abilities in both groups. [Conclusion] The estimated metabolic equivalents using accelerometer may be suitable to assess movement activity rather than motionless activity, and accelerometer demonstrated acceptable validity in people with subacute stroke.
[目的] 本研究旨在评估使用加速度计（Active Style Pro HJA 350-IT）对亚急性中风患者在体育活动期间估计的代谢当量进行已知组效度验证。[对象与方法] 10名亚急性中风患者和10名健康人进行了六项活动（躺卧、坐立、站立、坐位伸手任务、站立位伸手任务和行走），并在每项活动期间使用加速度计估计代谢当量。将这些估计的代谢当量与通过手册或先前研究报告的代谢当量进行比较。此外，还比较了亚急性中风患者和健康对照参与者之间估计的代谢当量。[结果] 与先前研究相比，两组在维持姿势期间估计的代谢当量值显著更低。与两组的手册代谢当量相比，在坐位伸手任务或站立位伸手任务期间估计的代谢当量之间没有显著差异。两组中行走期间估计的代谢当量与先前对步态能力较低的中风患者进行的研究相比，不可避免地存在显著差异。[结论] 使用加速度计估计的代谢当量可能适合评估运动活动而非静止活动，并且加速度计在亚急性中风患者中显示出可接受的效度。
