Effects of Core Stabilization Exercises on Pulmonary Function, Respiratory Muscle Strength, Peripheral Muscle Strength, Functional Capacity, and Perceived Appearance in Children With Adolescent Idiopathic Scoliosis A Randomized Controlled Trial

Objective: The aim of the study was to investigate the effects of core stabilization exercises on pulmonary function, respiratory muscle strength, peripheral muscle strength, walking capacity, and perceived appearance in children with adolescent idiopathic scoliosis. Design: This is an evaluator-blinded, randomized controlled trial. A total of 30 patients were randomly allocated to either a training group (n = 15, age = 13.8 +/- 2.8 yrs, Cobb angle = 19.3 +/- 6 degrees, Risser sign: n((1)) = 1; n((2-4)) = 14) or a control group (n = 15, age = 15.8 +/- 3.4 yrs, Cobb angle = 20.8 +/- 7.9 degrees, Risser sign: n((1)) = 1; n((2-4)) = 14). The training group received core stabilization exercises in addition to the traditional scoliosis exercises for 8 wks. The control group only received the traditional scoliosis exercises for 8 wks. Spirometry, maximal inspiratory and expiratory pressures, 6-min walking test, peripheral muscle strength, and the Walter Reed Visual Assessment Scale were assessed at the beginning and end of the study. Results: The training group showed statistically significant improvements in maximal inspiratory pressure, maximum expiratory pressure, and Walter Reed Visual Assessment Scale score (respectively, mean changes = 17.4 +/- 5.2 cmH(2)O; 10.6 +/- 4.3 cmH(2)O; 2.4 +/- 1.6), which were significantly larger compared with the control group (P < 0.05). Conclusions: Core stabilization exercises given in addition to the traditional scoliosis exercise can improve respiratory muscle strength and perceived appearance in patients with adolescent idiopathic scoliosis.
