Restless legs severity

International Restless Legs Syndrome Rating Scale

The International Restless Legs Scale records a patient's own ratings of restless-legs severity, collected by an examiner. This page is for clinics. It is not a diagnosis of restless legs syndrome and not a public test.

What is the IRLS?

The IRLS organises restless-legs severity for clinician review. A score is not a stand-alone RLS diagnosis and does not prescribe medication.

Development and clinical use

The International Restless Legs Syndrome Study Group developed the IRLS as a severity instrument, and Walters and colleagues published its validation in 2003.

RLS severity rating for clinician review

A structured clinical conversation

An examiner administers the ten questions to a patient who meets the IRLSSG diagnostic criteria for restless legs syndrome. The patient makes every rating from 0 to 4, and the examiner is available to clarify the questions. On Lirena the clinician records the patient's ratings in the workspace; the form is never sent to the client.

  • Prompt-by-prompt structure without replacing the interview
  • Space to record the clinician's ratings, not a client self-score
  • Review of what was covered before finishing
  • Results remain with the responsible clinician

Understand the measure and its scoring conventions

Published scoring adds the ten ratings for a total from 0 to 40, in bands of none (0), mild (1-10), moderate (11-20), severe (21-30) and very severe (31-40). Abetz and colleagues describe a symptoms subscale (items 1, 2, 4, 6, 7 and 8) and a symptoms impact subscale (items 5, 9 and 10). This public page does not independently verify scoring, cutoffs, or a production scoring rule.

What clinics ask before they evaluate the IRLS

These answers stay inside educational catalogue scope. They do not replace official manuals or clinician judgement.

Does IRLS diagnose restless legs syndrome?

No. It rates the severity of symptoms in a patient who already meets the diagnostic criteria. Diagnosis remains a clinician task.

Can I complete IRLS here?

No. This page does not collect answers or recommend treatment.

How is IRLS used on Lirena?

As an examiner-administered rating. The clinician records the patient's own ratings in the workspace and reviews the result with history rather than treating a score as a diagnosis.

Does a high IRLS score mean I need medication?

No. Treatment decisions remain with the responsible clinician.
