What is required for a diagnosis of fibromyalgia according to the American College of Rheumatology?

1. At least 5 tender points for greater than 3 months

2. At least 11 of 18 tender points for greater than 3 months

3. At least 8 tender points for a duration of 1 month

4. At least 15 tender points with one flare-up

The correct answer is: At least 11 of 18 tender points for greater than 3 months

For a diagnosis of fibromyalgia according to the American College of Rheumatology (ACR) criteria, the assessment includes the presence of at least 11 out of 18 specific tender points on examination, alongside a duration of symptoms greater than 3 months. This criterion emphasizes the widespread nature of pain and tender points that are characteristic of fibromyalgia. The tender points are standardized locations on the body where pressure induces pain, and the requirement of having 11 out of 18 ensures that the condition is properly identified, distinguishing it from other possible causes of widespread pain. By focusing on this significant number of tender points, clinicians can more accurately diagnose fibromyalgia and initiate appropriate management strategies. Other options suggest different thresholds or criteria that are not aligned with ACR guidelines, making them insufficient for a solid diagnosis. Thus, the requirement of 11 tender points effectively captures the essence of fibromyalgia as intended by the ACR.
