BACKGROUND AND PURPOSE
New coronavirus disease 2019 (COVID-19) can cause persistent symptoms and physical weakness that can lead to a limitation in activities of daily living (ADL). There is a lack of evidence about the performance in the six-minute step test (6MST) of post-COVID-19 patients and healthy subjects. The aim of this study is to investigate the cardiorespiratory response induced by the 6MST in post-COVID-19 patients and compare it with the response of the six-minute walk test (6MWT).
METHODS
This cross-sectional study was conducted on 34 post-COVID-19 patients and 33 healthy subjects. The assessment was performed at one month from a non-severe SARS-CoV-2 infection. Both groups were assessed by using the 6MST, 6MWT, and the pulmonary function test (PFT). Post COVID functional status (PCFS) scale was used for the post-COVID-19 group to assess functional status. Physiological responses; heart rate (HR), respiratory rate (RR), oxygen saturation (SpO), blood pressure (BP), and Borg scale for fatigue and dyspnea were recorded before and after the 6MST and 6MWT.
RESULTS
the performance of the post-COVID-19 group was worse than the healthy group in both tests. In 6MWT, the distance walked by the post-COVID-19 group (423 ± 7) was 94 m less than the healthy group, and the number of climbed steps in the 6MST (121 ± 4) was 34 steps less than the healthy group. Both results were statistically significant ( < 0.001). There was a moderate positive correlation between the 6MST and 6MWT in walked distance versus steps number (r = 0.5, < 0.001). In addition, there was a moderate correlation between the two tests in the post (HR, RR, SpO, systolic blood pressure SBP, diastolic blood pressure DBP, dyspnea, and fatigue) with < 0.001.
CONCLUSIONS
Six-minute step tests produced similar cardiorespiratory responses when compared to a 6MWT. The 6MST can be used as an assessment tool for COVID-19 patients to evaluate their functional capacity and ADL.
背景与目的
2019新型冠状病毒病（COVID-19）可导致持续症状和身体虚弱，进而限制日常生活活动（ADL）。目前缺乏关于COVID-19康复患者和健康受试者在六分钟步行试验（6MWT）中的表现的证据。本研究的目的是调查6MWT对COVID-19康复患者诱发的心肺反应，并将其与六分钟步行试验（6MWT）的反应进行比较。
方法
本横断面研究对34例COVID-19康复患者和33名健康受试者进行。评估在非重症SARS-CoV-2感染后1个月进行。两组均采用6MWT、6MWT和肺功能测试（PFT）进行评估。COVID-19康复组采用COVID-19后功能状态（PCFS）量表评估功能状态。记录6MWT和6MWT前后的生理反应；心率（HR）、呼吸频率（RR）、血氧饱和度（SpO）、血压（BP）以及疲劳和呼吸困难的Borg量表。
结果
在两项测试中，COVID-19康复组的表现均不如健康组。在6MWT中，COVID-19康复组行走的距离（423±7）比健康组少94米，在6MST中攀爬的步数（121±4）比健康组少34步。两项结果均具有统计学意义（<0.001）。在行走距离与步数方面，6MST和6MWT之间存在中度正相关（r=0.5，<0.001）。此外，两项测试在（HR、RR、SpO、收缩压SBP、舒张压DBP、呼吸困难和疲劳）方面存在中度相关性，<0.001。
结论
与6MWT相比，六分钟步行试验产生了相似的心肺反应。6MST可作为评估COVID-19患者功能能力和ADL的工具。
