Respiratory function, functional capacity, and physical activity behaviours in children and adolescents with scoliosis.

Objectives: To assess pulmonary function and functional capacity in children and adolescents with mild or moderate idiopathic scoliosis who were included in a rehabilitation programme, and to observe some of their physical activity behaviours.

Methods: Forty children (aged 9-17 years) with mild or moderate idiopathic scoliosis (patients) and 40 sex- and age-matched healthy controls were included in the study. Physical activity behaviours (hours of time spent at a desk and at a computer, hours of competitive and non-competitive practice of exercise per week) were recorded. Patients were assessed before beginning rehabilitation and 12 weeks after an exercised-based programme by spirometry and functional capacity testing (6-minute walk test).

Results: All respiratory and functional capacity parameters were significantly increased after physical therapy compared with before beginning physical therapy in patients. However, there were still differences between patients and controls in all assessed parameters after therapy. Children and adolescents who were diagnosed with scoliosis spent a longer time at a computer, and had reduced regular and competitive physical exercise compared with controls.

Conclusions: In children and adolescents with mild/moderate idiopathic scoliosis, pulmonary parameters and functional capacity are improved after 12 weeks of supervised physical therapy.
