title: Effects of Swiss ball exercise and resistance exercise on respiratory function and trunk control ability in patients with scoliosis.
abstract: [Purpose] This study compared the effects of Swiss ball exercise and resistance exercise on the respiratory function and trunk control ability of patients with scoliosis. [Subjects] Forty scoliosis patients were randomly divided into the Swiss ball exercise group (n= 20) and resistance exercise group (n = 20). [Methods] The Swiss ball and resistance exercise groups performed chest expansion and breathing exercises with a Swiss ball and a therapist's resistance, respectively. Both groups received training 30 min per day, 5 times per week for 8 weeks. [Results] Both groups exhibited significant changes in forced vital capacity, forced expiratory volume in one second, and trunk impairment scale after the intervention. However, there was no significant change in the forced expiratory volume in one second/forced vital capacity ratio after the intervention in either group. Meanwhile, forced expiratory volume in one second and trunk impairment scale were significantly greater in the resistance exercise group after the intervention. [Conclusion] Both Swiss ball exercise and resistance exercise are effective for improving the respiratory function and trunk control ability of patients with scoliosis. However, resistance exercise is more effective for increasing the forced expiratory volume in one second and trunk control ability.
