简要总结
assessment of the musculoskeletal system will be performed twice a year, for three years of young dancers
详细描述
Objectives: To examine musculoskeletal system characteristics in female dancers with and without scoliosis throughout the pubertal period, and to evaluate the effect of a targeted preventive exercise program.
Methods: Up to 140 female dancers aged 11-16 will be recruited for a two-phase study:
Phase A: a two-year longitudinal study with four assessment time points. . At each time point, participants will complete a comprehensive assessment including: anthropometric measurements (height and weight), sexual maturation status (Tanner scale), scoliosis assessment (Adam's forward bend test, scoliometer measurements, Scoliosis Research Society-22 questionnaire), bone strength (quantitative ultrasound using a Speed of Sound [SOS] device), abdominal and back muscle morphology (ultrasound imaging), hip muscle strength (handheld dynamometry), hip range of motion (goniometry), dynamic balance (Y Balance Test), and flexibility (Beighton score). In addition, participants will complete a demographic questionnaire and an injury surveillance questionnaire.
Phase B : an intervention study in which dancers with scoliosis will be randomly assigned to either a three-month targeted exercise program or a control group continuing regular training. Outcomes will be assessed post-intervention and at one-year follow-up.
