Key result
The RPE-face scale significantly correlated with physiological parameters during cardiopulmonary exercise testing, and a score of 4 accurately predicted the anaerobic threshold regardless of age, gender, or the presence of atrial fibrillation.
Why the study?
The Borg scale can be difficult for older adults to understand, and this study aimed to determine the validity of the face scale for rating perceived exertion in older adults and patients with AF during cardiopulmonary exercise testing.
Does the RPE-face scale accurately reflect physiological parameters and anaerobic threshold during exercise testing in older adults and patients with atrial fibrillation?
Observational (n=112)

Does the RPE-face scale accurately reflect physiological parameters and anaerobic threshold during exercise testing in older adults and patients with atrial fibrillation?
p-value: p=<0.01
The RPE-face scale is a valid and easily understood tool for determining exercise intensity and estimating the anaerobic threshold in older adults and patients with atrial fibrillation.
Supports RPE-face scale for exercise intensity assessment in older adults and AF; leaves open prospective validation before practice change.
BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: The RPE-face scale can be used to determine the intensity of physical exercise, unaffected by age, gender, SR, or AF.

Nashimoto et al. (2021) conducted an observational in Atrial fibrillation and sinus rhythm (n=112). Face scale for rating of perceived exertion (RPE-face scale) was evaluated on Prediction of anaerobic threshold using the RPE-face scale (p=<0.01). The RPE-face scale significantly correlated with physiological parameters during cardiopulmonary exercise testing, and a score of 4 accurately predicted the anaerobic threshold regardless of age, gender, or the presence of atrial fibrillation.
