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 .
Effects of dual-task cognitive-gait intervention on memory and gait dynamics in older adults with a history of falls: a preliminary investigation.
The present study highlights the effects of the dual-task cognitive-gait intervention ( CGI ) on working memory and gait functions in older adults with a history of falls . Thirteen older adults with a history of falls were recruited from local community centers and r and omly stratified into either the control ( n = 5 ) or experimental ( n = 8) group . The experimental group received the dual-task cognitive-motor intervention involving simultaneous motor ( walking ) and cognitive ( memory recall ) task whereas the control group received a placebo treatment ( walking with simple music ) . The intervention was provided 30 minutes per session , over a 6-week period . Memory measures included a combination of word recall and arithmetic task . Gait function measures included velocity and center of pressure ( COP ) stability . Non-parametric tests were used at p < 0.05 . The experimental group showed a greater memory performance than the control ( p < 0.05 ) . However , no significant intervention-related changes in gait velocity and stability were observed . Our findings provide the first evidence in literature to demonstrate that the long-term dual-task cognitive-motor intervention improved memory of older adults with a history of falls under the dual cognitive motor task condition
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 .
