Effect of a training program of overground walking on BTS gait parameters in elderly women during single and dual cognitive tasks.

We tested the hypothesis that a regular training program might reduce gait disturbances during dual cognitive-motor tasks in elderly women. This open-label experimental study comprised 53 postmenopausal women aged over 65, who were assigned to a 10-week training program (360 min/week). A BTS SMART system examination during free walking and during dual tasks [i.e., walking while performing either a simple (SCT) or a complex (CCT) cognitive task] was performed prior to the training program and again after it had finished. After the 10-week walking training program, a significant decrease was found in the duration of single support phase, double support phase, total support phase, and gait cycle, whereas values for such BTS parameters as swing speed, step length, and gait speed increased significantly. The greatest percentage deltas between the final and initial values of the respective BTS parameters concerned swing speed and gait speed irrespective of the kind of task undertaken while measurements were taken. A cognitive task, irrespective of the level of difficulty, performed during walking had the opposite effect on step width than expected. A 10-week training program significantly improved the cadency and manner of gait in elderly women, but did not change step width. Therefore, further study is needed to estimate the usefulness of cognitive-motor training programs for significant improvement in gait coordination during dual tasks in elderly women.
