A framework for the classification of joint hypermobility and related conditions.

This paper provides a framework for understanding and classifying joint hypermobility and its related disorders, particularly focusing on Ehlers-Danlos Syndrome (EDS). The authors emphasize the recent updates to the nosology of EDS, which now distinguishes over 20 subtypes and necessitates a unified set of criteria for diagnosing the hypermobility type of EDS and joint hypermobility syndrome. The document categorizes different types of joint hypermobility and their musculoskeletal manifestations, proposing a new concept called hypermobility spectrum disorders for patients with significant joint hypermobility symptoms that do not meet the criteria for other known syndromes. This classification aims to help clinicians better diagnose and manage patients who exhibit symptomatic joint hypermobility.
