Borg CR-10

The Borg Category-Rating scale or Borg CR-10 scale is a self-report tool to measure the intensity of perceived effort. The Borg CR-10 is similar to the Borg Rating of Perceived Exertion Scale, but ratings are from 0 to 10 rather than 6 to 20.

Theory
The scale scores perceived effort from 0 (no effort at all) to 10 (absolute maximum).

Evidence
The World Health Organization has suggested using the Borg CR-10 scale to assess effort when doing rehabilitation to recover from the effects of COVID-19.

Cost and availability
The RPE scale is copyrighted but is widely available and free to use in many hospitals or health settings, and on websites such as the World Health Organization and CDC.
