Type | Beighton score | Musculoskeletal involvement* | Notes |
---|---|---|---|
Asymptomatic joint hypermobility | |||
Asymptomatic generalized joint hypermobility | Positive | Absent | — |
Asymptomatic peripheral joint hypermobility | Usually negative | Absent | Joint hypermobility typically limited to hands and/or feet |
Asymptomatic localized joint hypermobility | Negative | Absent | Joint hypermobility limited to single joint or body parts |
Hypermobility spectrum disorders | |||
Generalized hypermobility spectrum disorders | Positive | Present | Does NOT meet criteria for hypermobile EDS based on limited findings in skin and musculoskeletal systems and lack of family history No genes identified Screening with echocardiography unnecessary |
Peripheral hypermobility spectrum disorders | Usually negative | Present | Joint hypermobility typically limited to hands and/or feet |
Localized hypermobility spectrum disorders | Negative | Present | Joint hypermobility limited to single joints or body parts |
Historical hypermobility spectrum disorders | Negative | Present | Historical presence of joint hypermobility |
EDS – Joint hypermobility with more pronounced skin and musculoskeletal findings and/or positive family history | |||
1. Hypermobile EDS | Positive | Possible | Meet criteria based on supportive findings in skin and body systems and/or positive family history (see Figure 2) No genes identified AD inheritance pattern Obtain screening echocardiography |
