Borg Rating of Perceived Exertion Scale
From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history
The Borg Rating of Perceived Exertion Scale or RPE scale is a self-report tool to measure the amount of effort needed to do a particular activity.[1]
Theory
The scale scores perceived effort from 6 (no effort at all) to 20 (absolute maximum, exhaustion). Fitter people feel like they are putting in less effort than less fit or deconditioned people who are doing the same activity.[1]
Evidence
The World Health Organization has suggested using the RPE scale to assess effort when covering from COVID-19.
Subgroup
Cost and availability
The RPE scale is free to use and readily available.
