This study demonstrates that virtual reality has an augmented effect on balance and associated locomotor recovery in adults with hemiparetic stroke when added to conventional therapy.

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 randomly 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.

This is the first empirical evidence highlighting the neural substrates mediating dynamic locomotion for different gait training modes and speeds. Fast, robot-assisted gait training best facilitated cortical activation associated with locomotor control.
