Abstract
[Purpose] The objective of this study was to investigate the effect of exercise intervention using a horse-riding simulator on frail seniors. [Subjects] The subjects were 28 frail seniors. [Method] The exercise intervention period and non-intervention period were 12 weeks. Before and after these periods, the times of one-leg standing with eyes open, Functional Reach Test, 5 m walking test, Timed Up and Go Test, thoracic kyphosis angle, lumbar flexure angle, and sacral inclination angle were measured. [Result] All measurements except the thoracic kyphosis improved. [Conclusion] The results indicate that exercise intervention using a horse-riding simulator was effective at improving the physical ability and spinal alignment of frail seniors.
