Numerical Rating Scale for Pain
The Numerical Rating Scale (NRS) is a simple, widely used tool for assessing subjective pain intensity in patients. Patients rate their pain on a scale from 0 to 10, where 0 represents no pain and 10 represents the worst pain imaginable. The NRS is one of the most frequently used pain assessment instruments in clinical practice due to its brevity, ease of administration, and strong psychometric properties across diverse patient populations.
