Evidence from subgroup comparisons showed no difference in treatment-related changes between cognitive-motor and motor-motor dual tasks , or when interventions were compared to active or inactive controls .
In summary , physical exercise interventions can improve dual-task walking in older adults primarily by increasing the speed at which individuals walk in dual-task conditions .
Currently , evidence concerning whether physical exercise interventions reduce DTC or alter the self-selected dual-task strategy during unobstructed walking is greatly lacking , mainly due to the failure of studies to measure and report reciprocal dual-task effects on the non-gait task
Dual-task interference during walking can substantially limit mobility and increase the risk of  falls among community-dwelling older adults .
Previous systematic review s examining intervention effects on dual-task gait and mobility have not assessed relative dual-task costs ( DTC ) or investigated whether there are differences in treatment-related changes based on the type of dual task or the type of control group .
The purpose of this systematic review was to examine the effects of physical exercise interventions on dual-task performance during walking in older adults .
Transfer effects of fall training on balance performance and spatiotemporal gait parameters in healthy community-dwelling older adults: a pilot study.
This study examined transfer effects of fall training on fear of falling ( Falls Efficacy Scale-International [ FES-I ] ) , balance performance , and spatiotemporal gait characteristics in older adults . Eighteen community-dwelling older adults ( ages 65 - 85 ) were r and omly assigned to an intervention or control group . The intervention group completed 12 training sessions ( 60 min , 6 weeks ) . During pre- and posttesting , we measured FES-I , balance performance ( double limb , closed eyes ; single limb , open eyes ; double limb , open eyes with motor-interfered task ) , and gait parameters ( e.g. , velocity ; cadence ; stride time , stride width , and stride length ; variability of stride time and stride length ) under single- and motor-interfered tasks . Dual tasks were applied to appraise improvements of cognitive processing during balance and gait . FES-I ( p = .33 ) and postural sway did not significantly change ( 0.36 < p < .79 ) . Trends toward significant interaction effects were found for step width during normal walking and stride length variability during the motor dual task ( p = .05 , ηp 2 = .22 ) . Fall training did not sufficiently improve fear of falling , balance , or gait performance under single- or dual-task conditions in healthy older adults
Evidence from subgroup comparisons showed no difference in treatment-related changes between cognitive-motor and motor-motor dual tasks , or when interventions were compared to active or inactive controls .
