GlossaryHypermobility Spectrum Disorder (HSD)

group of conditions with overly flexible joints causing pain and instability

Hypermobility Spectrum Disorder (HSD) is a group of conditions characterized by joints that move beyond the normal range of motion, often leading to pain, instability, and an increased risk of injury. It encompasses a range of symptoms from benign joint hypermobility to more severe forms that can affect daily functioning and quality of life. HSD is distinct from other connective tissue disorders like Ehlers-Danlos Syndrome, although they can share similar features.
