The effect of a core exercise program on Cobb angle and back muscle activity in male students with functional scoliosis: a prospective, randomized, parallel-group, comparative study

초록

Objective To assess the effect of core strengthening exercises on Cobb angle and muscle activity in male college students with functional scoliosis. Methods Static and dynamic back muscle activity were evaluated via surface electromyography (sEMG). A core exercise protocol comprising 18 exercises was performed three times/week for 10 weeks. Patients were randomly allocated to either a home- or community-based exercise programme. Cervical thoracolumbar scans and sEMG were performed after 10 weeks. Results A total of 87 students underwent cervical thoracolumbar scans. Of these, 53 were abnormal and were randomised between the home-based (n=25) or community-based (n=28) groups. After the 10-week exercise programme, Cobb angles were significantly lower and back muscle strength was significantly improved than baseline in both groups, but there were no statistically significant between group differences. Conclusions A 10-week core strengthening exercise programme decreases Cobb angle and improves back muscle strength in patients with functional scoliosis.
