The objective of this study was to describe the psychometric properties and physiological response of the five times sit-to-stand (STST-5) and 60-sec sit-to-stand test (STST-60) in adults with heart failure (HF).
People with HF enrolled in a 12-wk exercise rehabilitation program completed two STST-5 and two STST-60 as part of their usual baseline and follow-up assessments. Test-retest reliability, validity, and responsiveness of the two STSTs were described. Results were correlated with the 6-min walk test (6MWT) and timed up and go test (TUGT), and rating of perceived exertion and physiological responses were compared between all tests. Feasibility was also reported according to the presence of adverse events and adherence to the protocol.
Forty-nine adults with HF participated in this study. Intraclass correlation coefficients of the STST-5 and STST-60 were 0.91 (95% CI, 0.78-0.96) and 0.96 (95% CI, 0.93-0.98), respectively. The STST-60 was strongly associated with both the 6MWT ( r = 0.76) and the TUGT ( rs =-0.77). The STST-5 was strongly associated with the TUGT ( rs = 0.79) and moderately associated with the 6MWT ( rs =-0.70). Rating of perceived exertion and lower limb fatigue were greater in the STST-60 than in the 6MWT ( P < .001) or STST-5 ( P < .001). Adverse events occurred in five participants undertaking the STST-60 and one participant undertaking the STST-5.
The STST-5 and STST-60 are reliable and valid measures of functional exercise capacity in people with HF.
本研究的目的是描述心力衰竭（HF）成人患者五次坐立试验（STST - 5）和60秒坐立试验（STST - 60）的心理测量学特性和生理反应。
参加为期12周运动康复计划的HF患者完成两次STST - 5和两次STST - 60，作为其常规基线和随访评估的一部分。描述了两种STST的重测信度、效度和反应性。将结果与6分钟步行试验（6MWT）和计时起立行走试验（TUGT）进行相关性分析，并比较所有试验之间的主观用力程度评分和生理反应。还根据不良事件的发生情况和对方案的依从性报告了可行性。
49名HF成人参与了本研究。STST - 5和STST - 60的组内相关系数分别为0.91（95%CI，0.78 - 0.96）和0.96（95%CI，0.93 - 0.98）。STST - 60与6MWT（r = 0.76）和TUGT（rs = -0.77）均密切相关。STST - 5与TUGT（rs = 0.79）密切相关，与6MWT中度相关（rs = -0.70）。STST - 60中的主观用力程度评分和下肢疲劳程度高于6MWT（P <.001）或STST - 5（P <.001）。进行STST - 60的5名参与者和进行STST - 5的1名参与者发生了不良事件。
STST - 5和STST - 60是HF患者功能性运动能力的可靠且有效的测量方法。
