[Purpose] This study investigated the effect of a motor dual-task balance program on balance and gait of elderly women to suggest a more effective balance exercise method. [Subjects] Twenty elderly Korean women who could walk independently were recruited from the community dwelling. [Methods] The motor dual-task balance training (experimental) group stood on an Aero-step, and performed gym ball bouncing, catching, and throwing, while the simple task balance training (control) group merely stood on the Aero-step. Participants performed 45 minutes of training, 2 times a week for 6 weeks. Balance (fall index) was measured using a TETRAX. Gait variables were recorded on a GAITRite walkway at self-determined walking speed. [Results] The fall index of the experimental group was significantly lower than that of the control group. Step length, stride length, velocity, and cadence of the experimental group improved significantly more than those of control group. [Conclusions] We found that motor dual-task balance training improved balance and walking ability more than simple balance training. Further studies should investigate motor dual-task training with kinematic and kinetic data, and muscle activation based on motor strategies.
