To compare the effects of single- versus dual-task balance training on the gait smoothness and balance of community-dwelling older adults, 69 volunteers were randomized to single-, dual-task training, and control (no intervention) groups. Exercises were received in 18 sessions through 6 weeks. The gait smoothness was measured by the harmonic ratio of trunk accelerations using a triaxial accelerometer. Balance performance was assessed through the Fullerton Advanced Balance scale, Timed Up and Go test, Activities-specific Balance Confidence, and gait speed. After the trial, all variables improved significantly in the training groups. Moreover, differences in the mean change of all variables, except the Timed Up and Go test, were statistically significant between the interventional groups and the control group, but no significant difference was reported between the two training groups. This study suggests that balance training can improve gait smoothness as well as balance status in healthy older adults.
