Symptoms can include the inability to walk properly or for long distances, and pain in affected areas.

[5] In March 2017, the International Consortium on the Ehlers-Danlos Syndromes published a revised classification naming two syndromes: hypermobile EDS (hEDS), which has narrowly defined criteria, and hypermobility spectrum disorder (HSD) for those with some but not all the features of hEDS.

[6][7][8] This reclassification aimed to address the overlap between joint hypermobility syndrome and what was previously termed EDS-hypermobile type (EDS-HT).

[5][6] HSD is further classified into different subtypes, which include:[6] These classifications help in identifying the specific pattern and extent of joint hypermobility and in determining the appropriate management strategies.

As hypermobility syndrome can be easily mistaken for being double-jointed or categorised as nothing more than perhaps an achy body from lack of exercise, medical professionals may diagnose those affected incorrectly and not adequately investigate the symptoms.

As those with HSD experience a considerable amount of discomfort, it is important to focus on the treatment, not the labels.

In particular, musculoskeletal involvement is a requirement for diagnosis with any form of hypermobility spectrum disorder but not for hypermobile Ehlers–Danlos syndrome.
