Pain scales are widely used to measure a patient’s pain intensity and type. There are many different scales available, including those for infants, children, adults and patients with difficulties communicating. Some are self-reporting and others observational.
Self-reporting - adult
Numerical rating scale
Perhaps the most widely known and used pain scale. Patients are asked to rate their pain on a scale of 0-10, where 0 is no pain and 10 is worst pain imaginable, either verbally or by placing a mark along a line.
Visual Analogue Scale
This requires patients to indicate their current level of pain along a scale with ‘no pain’ at one end and ‘worst pain imaginable’ at the other.
