This article aims to investigate the effects of
dual-task training in the gait and balance of post-stroke
individuals via a systematic review with meta-analysis of
clinical trials with adequate methodological quality. Searches
in the electronic databases PubMed, Lilacs, SciELO, PEDro,
up to September 2024, by two independent researchers.
We included randomized clinical trials, with dual-task training
in post-stroke individuals, with an average PEDro scale score
of six or higher. The outcome measures of interest were any
related to gait and/or balance, which could be assessed
using tests or questionnaires. Study methodological quality
was assessed using the PEDro scale. Eight studies were
included. Overall, dual-task training showed to be effective
in improving gait speed by 0.11 m/s (95%CI 0.02–0.21; I2=11%;
p=0.02), cadence by 7.30 steps/minute (95%CI 2.46–12.14;
I2=0%; p=0.003), and balance (SMD 0.45; 95%CI 0.08–0.81;
I2=36%; p=0.02). No significant results were found for stride length (SD 1.72; 95%CI −9.15–12.59; I2=22%; p=0.76) and mobility
(95%CI −5.64–1.88; I2=0%; p=0.33). This systematic review showed,
via meta-analysis, that dual-task training can significantly improve
gait speed, cadence, and balance in post-stroke individuals. However,
we recommend new clinical trials, with higher methodological
quality, especially studying the effects on mobility and balance
