Thoracic hyperkyphosis is associated with postural abnormality, physical function, and quality of life. This study aimed to examine the effects of a combined exercise program on the spinal curvature and balance ability in adolescents with kyphosis. Fifty-one adolescents (mean age 21.95 ± 3.90 year, 23 male and 28 female) diagnosed with kyphosis were randomly divided into two groups: an experimental group (n = 25) and a control group (n = 26). All participants in the study group underwent a combined exercise program for 60 min, three times per week, for 12 weeks. Cobb’s angle and forward head angle showed significant differences between the two groups (p < 0.001). The anterior and posterior weight distributions of static and dynamic plantar foot pressures showed a significant difference between the two groups (p < 0.001), and significant differences were observed only in the study group (p < 0.001). However, the left and right static plantar foot pressures did not differ significantly. In conclusion, these results demonstrate that a combined exercise program is an effective intervention for the improvement of alignment in the spinal curve and balance in adolescents with postural kyphosis.
