[Purpose] The purpose of this study was to identify the effects of task-oriented training with altered somatosensory input on the balance ability of chronic stroke patients. [Subjects and Methods] Twenty-six subjects with chronic stroke were divided into an experimental group (n=14) and a control group (n=12). Both groups attended physical therapy sessions five times a week for four weeks. The experimental group performed additional, task-oriented training with altered sensory input three times a week for four weeks. Limit-of-stability tests were conducted before and after the intervention. In addition, all subjects were evaluated using the Berg Balance Scale (BBS) and Korean Activities-Specific Balance Confidence Scale before and after the intervention. [Results] There was a significant interaction between time and group on BBS scores, on the total surface area of the limit of stability, and on the surface area of the limit of stability of the affected side. However, an analysis of covariance in which the baseline values of each variable served as the covariates showed that only the post-intervention BBS score of the experimental group was significantly higher than that of the control group. [Conclusion] Task-oriented training with altered somatosensory input can improve functional balance in patients with chronic stroke.
