The joint hypermobility syndrome, also abbreviated JHS and the hypermobility spectrum disorder, also known as HSD are new terminology often used to describe the most common hereditary disorder of connective tissue diseases.  Connective tissue diseases include joint hypermobility syndrome, or the hypermobility spectrum disorder, Ehlers-Danlos syndrome, Marfan syndrome, osteogenesis imperfecta, Stickler syndrome.  Connective tissue disease disorders do not generally include lupus, rheumatoid arthritis, Sjogren’s disease, scleroderma, mixed connective tissue disease, vasculitis and other related rheumatologic diseases, although these diseases can give pain throughout the body and joints and muscles. They are usually not associated with connective tissue disorders unless there are two separate disease entities existing.
