Features of screening diagnostics of joint hypermobility in primary school children

Abstract

Joint hypermobility is a little-studied and relatively new risk factor for Russian school medicine, leading to impaired functions of the musculoskeletal system. The study involved 50 conditionally healthy children of primary school from 7 to 8.4 years. Main group consisted of 26 students of the 1st grade (12 boys, 14 girls) of the village school "Podosinki" (Moscow region). Сomparison group consisted of 24 female athletes (engaged in rhythmic gymnastics for at least one year) from 7.7 to 8.3 years, living in Moscow and Moscow region. All children underwent a detailed study of the volume of passive movements in the wrist, elbow, knee and hip joints, as well as in the small joints of the hand; Postural changes were determined by non-invasive methods. Comparison of the results in both groups showed that all respondents equally have risk factors for the development of orthopedic diseases and pathological conditions: posture disorders (kyphoscoliotic type), valgus installation of feet and flattening of their arches of the feet (mobile flat feet), hypermobility of the joints. The results of the study questioned the adequacy of the assessment of hypermobility on the Beighton scоre in children of this age group; According to studies, further research is needed to find a measure of joint hypermobility in children. The study was conducted with the support of the Ministry of Education of Russia. Key words: joint hypermobility, children, musculoskeletal system, risk factors
