Different from control group (); different from DT 7 in the same group; DT ABC: dual-task while reciting alternate letters of alphabet; DT 7: dual-task while serially subtracting 7’s from 100; DT 3: dual-task while counting, leaving out multiples and numbers including 3; DTC: dual-task cost; values are mean ± standard deviation.
