The Borg scale is used to determine exercise intensity in rehabilitation but can be difficult for older adults to understand. By contrast, face scale that are used to evaluate pain are much easier to understand thanks to the inclusion of illustrations. On the other hand, the prevalence of atrial fibrillation (AF) increases with age. This study aimed to determine the validity of the face scale for rating perceived exertion (RPE-face scale) in older adults and patients with AF during cardiopulmonary exercise test. Furthermore, the relationship between face scale and anaerobic threshold (AT) was also investigated.
A total of 90 patients with sinus rhythm (SR) (74 men, 16 women) and 22 with AF were enrolled. Participants' responses were recorded using the RPE-face scale and compared with exercise intensity, heart rate, oxygen uptake, and minute ventilation during the exercise test. We determined the AT by the V-slope method.
Correlations between RPE-face scale and physiological parameters were significantly positive for men with SR and women with SR and AF. However, differences in the correlation coefficient between age and SR or AF were not statistically significant. The cutoff value for AT of the RPE-face scale was "4," showing high sensitivity and specificity.
The RPE-face scale can be used to determine the intensity of physical exercise, unaffected by age, gender, SR, or AF.
Borg 量表常用于康复运动强度的评定，但老年人理解起来可能较为困难。相比之下，用于评估疼痛的脸谱量表由于包含了插图而更容易理解。另一方面，房颤（AF）的发病率随着年龄的增长而增加。本研究旨在确定在心肺运动试验中用于评定感知运动强度的脸谱量表（RPE-脸谱量表）在老年患者和 AF 患者中的有效性。此外，还研究了脸谱量表与无氧阈（AT）之间的关系。
共纳入 90 名窦性心律（SR）患者（74 名男性，16 名女性）和 22 名 AF 患者。参与者使用 RPE-脸谱量表记录他们的反应，并将其与运动试验过程中的运动强度、心率、摄氧量和分钟通气量进行比较。我们通过 V 斜率法确定 AT。
SR 男性和 SR 及 AF 女性的 RPE-脸谱量表与生理参数之间的相关性呈显著正相关。然而，年龄与 SR 或 AF 之间的相关系数差异无统计学意义。RPE-脸谱量表的 AT 截断值为“4”，具有较高的灵敏度和特异性。
RPE-脸谱量表可用于确定运动强度，不受年龄、性别、SR 或 AF 的影响。
