Impact of generalized joint hypermobility on quality of life and physical activity in school-aged children: a longitudinal study

Le résumé fourni par la source

Generalized Joint Hypermobility (GJH) offers flexibility that could enhance motor activities. However, if it leads to injury and pain, it increases functional difficulties and activity limitations. The far-reaching consequences of activity limitations and restricted participation include poor physical fitness and diminished quality of life. This study investigated whether variations in joint mobility are associated with physical activity levels, physical fitness, and overall quality of life (QoL) among children and whether these factors change over a 2-year period. One hundred and sixty-five school-aged children were recruited at the beginning of a two-year longitudinal study. One hundred and eleven children were measured three times at one-year intervals. Joint mobility was classified as normal mobile, mobile, or hypermobile. The children were administered the FACES pain scale, the child activity limitation interview, a physical activity questionnaire, and the pediatric quality of life inventory questionnaire. Additionally, the 20-meter shuttle run was used to estimate aerobic fitness. In this study, pain was unrelated to joint mobility. The activity limitations of our study population were not different at baseline or at the end of the study, irrespective of joint mobility. Children with GJH had significantly lower physical activity levels at the end of the study. Overall, QoL increased over time, and aerobic capacity decreased. However, changes in children with GJH were not significantly different from those in children with normal mobility in this respect. Children with GJH were moderately active, however significantly less than children with normal mobility. Joint mobility had no significant effect on activity limitations, physical fitness or QoL. What is known? • Increased joint mobility reduces physical activity levels. What is new? • Children with GJH were not more limited in their activities than those with normal mobility, as measured by the activity limitation interview. • Children with GJH do not have a greater risk of developing pain-related activity limitations. • The quality of life did not differ between children with and without GJH.
