The most widely accepted set of diagnostic criteria for fibromyalgia was developed in 2010 by the Multicenter Criteria Committee of the American College of Rheumatology. A patient satisfies diagnostic criteria for fibromyalgia if the following 3 conditions are met:[1][2][3][4]
Widespread pain index (WPI) > 7 and symptom severity (SS) scale score >5 or WPI 3–6 and SS scale score >9
Symptoms have been present at a similar level for at least 3 months
The patient does not have a disorder that would otherwise explain the pain
The most widely accepted set of diagnostic criteria for fibromyalgia was developed in 2010 by the Multicenter Criteria Committee of the American College of Rheumatology.[1][2][3][4] and updated in 2016[5].
These criteria are not well used in clinical practice[6].
Competing criteria are by a collaboration between the US Food and Drug Administration (FDA) and the American Pain Society (APS) called the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks (ACTTION). These criteria are called the ACTTION-APS Pain Taxonomy (AAPT)[7]. These criteria have been criticized for not including a summary assessment of severity[8].
Multisite pain (MSP) "defined as 6 or more pain sites from a total of 9 possible sites"
"Moderate to severe sleep problems OR fatigue"
"MSP plus fatigue or sleep problems must have been present for at least 3 months"
1. WPI: Note the number of areas in which the patient has had pain over the last week. In how many areas has the patient had pain?
Score will be between 0 and 19.
Areas for pain are: shoulder girdle, left hip (buttock and trochanter), left jaw, left upper back, shoulder girdle, right hip (buttock and trochanter), right jaw, right lower back, upper arm, left upper leg, left chest, neck, upper arm, right upper leg, right abdomen, right lower arm, left lower leg, left lower arm, and right lower leg
2. Somatic symptoms (SS) scale score: For each of the 3 symptoms below, indicate the level of severity over the past week using the following scale:
0 = no problem
1 = slight or mild problems, generally mild or intermittent
2 = moderate, considerable problems, often present and/or at a moderate level
The SS scale score is the sum of the severity of the 3 symptoms (fatigue, waking unrefreshed, cognitive symptoms) plus the
extent (severity) of somatic symptoms in general. The final score is between 0 and 12.
Added "generalized pain criterion to insure that regional pain syndromes are not captured by the criteria". This criterion is pain in at least 4 of 5 regions. The five regions are 4-quadrant plus axial:
Left upper region: jaw, shoulder girdle, upper arm, lower arm
Right upper region: jaw, shoulder girdle, upper arm, lower arm
Left lower region: hip (buttock, trochanter), upper leg, lower leg
Right lower region: hip (buttock, trochanter), upper leg, lower leg
