Background
hypermobility, musculoskeletal pain
SECONDARY
Joint hypermobility, characterized by excessive rangeof movement, is observed in 7–36% of children and adolescents [Joint hypermobility does not appear to be directly linked to physical activity impairment but is associated with repetitive use injuries [Joint hypermobility may also be a risk factor for the development of widespread musculoskeletal pain during later adolescence, such as exhibited in JFM [The aim of this study was to better understand how joint hypermobility may affect functioning in a sample of adolescents with JFM, given the high degree of clinical overlap. We performed a secondary analysis of data collected as part of a pilot randomized clinical trial [
