Numeric Rating Scale (NRS)
The numeric rating scale is one of the most commonly used pain scales in medicine. The NRS consists of a numeric version of the visual analog scale. The most common form of the NRS is a horizontal line with an eleven point numeric range. It is labeled from zero to ten, with zero being an example of someone with no pain and ten being the worst pain possible. This type of scale can be administered verbally. It can also be administered via paper to be completed physically.
The numeric rating scale is a scale designed to help assess the extent of an individul's pain and improve communication regarding pain with health care providers. This scale can help guide the diagnostic process, track the progression of the pain, and more. Many hospitals use the NRS on whiteboards in hospital rooms daily to measure pain levels.
