Hypermobility Types of HMS Hypermobility Spectrum Disorder HSD: Symptoms Everyone will experience different symptoms and to varying degrees. Most people will only experience some of the symptoms listed below. Symptoms of HSD can include Pain Fatigue Frequent injuries, including dislocations, subluxations, sprains and microtraumas Poor proprioception/clumsiness Many of the symptoms listed below seem to be common in patients with HSD or hEDS but the links are not yet understood. Research has indicated that there is a link between autistic spectrum disorders and hypermobility related disorders, but again the link is not yet understood. Severity The severity of symptoms can vary hugely both between individuals and over time. Some can be mildly affected, with intermittent issues that have very little impact on day to day life – especially when managed through appropriate physiotherapy, pacing, and joint care. Other individuals may be much more severely affected. It is important to recognise that HSD is not inherently milder than hEDS, in fact recent studies have shown no difference in symptom severity. Management is based on addressing the current symptoms.
