Dual‑task exergaming to enhance motor and cognitive function in chronic stroke: a prospective, assessor-blinded, parallel group randomized controlled trial.
Sungbae Jo, Hyemin Kim, Changho Song
PMID 41715216WHAT IT FOUND
In chronic stroke survivors, four weeks of dual-task exergaming improved dynamic gait and executive function more than conventional balance training alone.
Both groups also received standard therapy, so the specific benefit of the game versus extra practice time is unclear.
Key findings
01The exergaming group showed significantly greater improvement in the Functional Gait Assessment score compared to the general balance training group.
02The exergaming group demonstrated significantly greater reductions in time and errors on the Trail Making Test Part B, indicating better executive function and processing speed.
03There were no significant differences between the groups in Stroop Test performance, suggesting the training did not transfer to this specific measure of selective attention.

What it does not show
The sample size was small (26 participants), which limits the generalizability of the findings. The intervention period was short (four weeks), so long-term retention of benefits is unknown. Both groups received standard rehabilitation, making it difficult to isolate the specific effect of the exergaming versus the additional therapy time. Practice effects on cognitive tests like the Trail Making Test cannot be ruled out. The study did not include a no-treatment control group, so natural recovery or placebo effects cannot be fully excluded.

The easy way to misread this
Do not assume the exergaming platform itself is the sole cause of improvement, as both groups received standard inpatient rehabilitation alongside their assigned training. The benefit may partly stem from increased overall therapy intensity rather than the specific technology.
