Purpose: This study was conducted to investigate whether therapeutic exercise has effectiveness on the balance and gait in older adults. Methods: 30 patients were participated in this study. To evaluate the effects of therapeutic exercise, patients were evaluated by using One leg stand test which was static balance test, Berge balance test, Functional reach test and Get up and go test which was dynamic balance test. Finally Gait pattern were assessed by using 3-dimensional gait analysis system. The assessment parameters were evaluated before and after treatment. And we received a consent form from all patients. The data were analyzed by paired t-test for compare pre and after therapeutic exercise. Results: One leg stand test was significantly increased after than before therapeutic exercise. Get Up and Go test was significantly decreased after than before therapeutic exercise. Functional Reach test was significantly increased after than before therapeutic exercise. Burge Balance test was significantly increased after than before therapeutic exercise. Stride length was significantly increased after than before therapeutic exercise. Cadence was significantly increased after than before therapeutic exercise. Velocity was significantly increased after than before therapeutic exercise. Conclusion: We thought that therapeutic exercise that is mat exercise has effectiveness on the balance and gait in older adults.
