1990 American College of Rheumotology (ACR) Classification Criteria: Overview
The 1990 ACR Classification Criteria requires the assessment of 2 key elements:
- Presentation of chronic widespread pain* for 3 months or more in all 4 quadrants of the body1, as well as a range of symptoms:
- Allodynia: a heightened sense of pain in response to normal stimuli (eg, a hug or handshake)2
- Hyperalgesia: (eg, when a small pinprick causes a sharp, stabbing pain)3
- Pain in at least 11 of 18 tender points upon palpation as assessed by the Manual Tender Point Exam1
- Use the checklist to determine if a patient fits the ACR criteria for Fibromyalgia4
* Widespread pain is defined as pain above and below the waist, on the left and right sides of the body, and in the axial skeleton.

Use the following checklist to determine whether a patient fits the American College of Rheumatology (ACR) criteria for a diagnosis of fibromyalgia.3
How to perform the ACR Tender Point exam:
- Locate each tender point visually and then with light palpation
- Use the thumb pad of your dominant hand to apply pressure perpendicularly
- Gradually increase thumb pressure until you reach a pressure of 4 kg/cm2 (enough to whiten your fingernail)
- Each survey site should be pressed once for a total of 4 seconds
- After applying pressure at the site, ask patient whether there was any pain and ask her/him to rate the intensity of pain on a scale of 0 to 10
- Evaluate control locations (over the thumb, mid-forearm, or forehead) for pain
Check all conditions that apply.
- ____ The patient has experienced chronic widespread pain for 3 months or more in all 4 quadrants
Widespread pain is defined as:
- Pain above and below the waist
- Pain on the left and right sides of the body
- Pain in the axial skeleton
(All 3 conditions above must be met to fit the definition of widespread pain.)
- ____ The patient experiences pain on palpation in at least 11 of the 18 tender points on the 3-D model.
