From the Research
The Beighton score should not be used as the primary tool to diagnose generalized joint hypermobility, as its ability to reflect joint hypermobility is limited and may not accurately identify hypermobility in all joints, as suggested by the most recent study 1. The Beighton score is a standardized method used to assess joint hypermobility, which is excessive flexibility in joints. The score evaluates nine points of flexibility: both little fingers (passive dorsiflexion beyond 90 degrees), both thumbs (passive opposition to the flexor aspect of the forearm), both elbows (hyperextension beyond 10 degrees), both knees (hyperextension beyond 10 degrees), and forward flexion of the trunk with knees straight (palms flat on the floor). Each positive test scores one point, for a maximum total of 9 points. Some of the key points to consider when using the Beighton score include:
- The score has been shown to have limited validity as a measure of generalized joint hypermobility, particularly in certain populations such as athletes 1.
- The score may not accurately identify hypermobility in all joints, as it primarily assesses upper limb joints and does not account for other major joints 2.
- A score of 4 or higher is generally considered indicative of joint hypermobility syndrome, but this cutoff may not be universally applicable and may require adjustment based on individual patient characteristics 3.
- The Beighton score should be used in conjunction with other clinical assessments and patient history to provide a comprehensive evaluation of joint hypermobility, as suggested by studies 4, 5. It's also important to note that joint hypermobility exists on a spectrum and varies with age, gender, and ethnicity. While the test is simple to perform in clinical settings, it should be interpreted alongside the patient's medical history and symptoms, as hypermobility can be associated with chronic pain, joint instability, and other complications.
