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 .
Balance training with multi-task exercises improves fall-related self-efficacy, gait, balance performance and physical function in older adults with osteoporosis: a randomized controlled trial
Objective : To evaluate the effects of a balance training program including dual- and multi-task exercises on fall-related self-efficacy , fear of falling , gait and balance performance , and physical function in older adults with osteoporosis with an increased risk of falling and to evaluate whether additional physical activity would further improve the effects . Design : R and omized controlled trial , including three groups : two intervention groups ( Training , or Training+Physical activity ) and one Control group , with a 12-week follow-up . Setting : Stockholm County , Sweden . Participants : Ninety-six older adults , aged 66 - 87 , with verified osteoporosis . Interventions : A specific and progressive balance training program including dual- and multi-task three times/week for 12 weeks , and physical activity for 30 minutes , three times/week . Main measures : Fall-related self-efficacy ( Falls Efficacy Scale-International ) , fear of falling ( single-item question – ‘ In general , are you afraid of falling ? ’ ) , gait speed with and without a cognitive dual-task at preferred pace and fast walking ( GAITRite ® ) , balance performance tests ( one-leg stance , and modified figure of eight ) , and physical function ( Late-Life Function and Disability Instrument ) . Results : Both intervention groups significantly improved their fall-related self-efficacy as compared to the controls ( p ≤ 0.034 , 4 points ) and improved their balance performance . Significant differences over time and between groups in favour of the intervention groups were found for walking speed with a dual-task ( p=0.003 ) , at fast walking speed ( p=0.008 ) , and for advanced lower extremity physical function ( p=0.034 ) . Conclusions : This balance training program , including dual- and multi-task , improves fall-related self-efficacy , gait speed , balance performance , and physical function in older adults with osteoporosis
