OBJECTIVE: To investigate the effects of dual task balance training in the
elderly on standing postural control while performing a cognitive task. DESIGN: A
randomized two-group parallel controlled trial.
PARTICIPANTS: Forty-three
subjects (all >65 years old) were enrolled in the study and were assigned
randomly to either an experimental group (n = 21) or a control group (n = 22).
INTERVENTIONS: Subjects in the experimental group were given strength and balance
training while performing cognitive tasks simultaneously. Subjects in the control
group were given strength and balance training only. The training was
administered twice a week for three months. MEASUREMENTS: The Chair Stand Test,
Functional Reach Test, Timed Up and Go Test and Trail Making Test were measured.
The sway length of the centre of gravity was measured during standing while
performing the Stroop task. The rate of Stroop task was also measured. All
measurements were collected at baseline and after the training period. RESULTS:
There were no significant differences in Functional Reach Test, Timed Up and Go
Test and sway length at baseline and after training between the two groups.
However, the rate of Stroop task (P < 0.05) was significantly higher after
training in the experimental group than in the control group. CONCLUSIONS: These
results suggest that dual task balance training in elderly people improves their
dual task performance during standing postural control.
