The purpose was to determine whether balance and mobility
training (BMT) or balance and mobility plus cognitive training (BMT+C) would
reduce postural sway and reaction time (RT) and maintain these improvements after
a 12-week follow-up in healthy older adults. METHODS: Participants were allocated
to the BMT (n=15; age: 70.2+/-3.2), BMT+C (n=14; age:68.7+/-5.5), or control
group (n=13; age: 66.7+/-4.2). The BMT group trained one-on-one, 3x/wk for 12
weeks on a balance obstacle course. The BMT+C group trained one-on-one, 3x/week
for 12 weeks on a balance obstacle course while completing cognitive tasks.
Participants stood on a force plate for 30s in feet-apart (FA) and semi-tandem
(ST) positions while completing simple RT and choice RT tasks at baseline, at the
12-week post-training, and at the 12-week follow-up. Participants were instructed
to stand as still as possible while verbally responding as fast as possible to
the auditory cues. RESULTS: No group differences in center of pressure (COP)
Area, COP Velocity, or Sample Entropy of the COP displacement were shown after
the training or 12-week follow-up, but the BMT and BMT+C showed faster RT after
training and maintained these improvements at the 12-week follow-up compared to
the control group. No differences in postural sway or RT emerged between the BMT
and BMT+C groups. CONCLUSION: Both training groups improved RT after the
interventions and sustained these improvements over 12 weeks, but showed no
reductions in postural sway. Multi-task balance training likely results in reduced attention demand.
