Enhancing post-stroke gait: effects of a 12-week core exercise intervention in hemiparetic survivors

Walking impairment is a major limitation following hemiparetic stroke, reducing functional independence and quality of life. Core-focused exercise has shown potential to enhance trunk stability and gait, yet evidence across different levels of motor impairment remains limited. This study investigated the effects of a 12-week structured core exercise programme on walking speed in 20 hemiparetic stroke survivors (10 males, 10 females; age 20–69 years). Walking performance was assessed using the 10-Meter Walk Test at fast (10MWT-FWV) and self-selected walking velocity (10MWT-SSWV) at baseline, Week 4, Week 8, and Week 12. Participants were stratified by baseline motor impairment, including a very severe subgroup (n=11). Changes over time were analysed using Friedman’s test, with post hoc Wilcoxon signed-rank tests and Bonferroni adjustments. Participants were also classified as high or low responders based on median velocity changes. Significant improvements were observed in both 10MWT-FWV and 10MWT-SSWV over 12 weeks (p < .01). The very severe impairment subgroup showed delayed but meaningful gains, with significant improvements by Week 8 and Week 12. High responders achieved markedly greater velocity gains than low responders (p < .01), reflecting variability in recovery trajectories. Exceptional gains in select participants highlight the potential for substantial functional improvements even in those with profound baseline deficits. In conclusion, a 12-week core exercise intervention enhances walking speed in hemiparetic stroke survivors, including those with severe impairments. These findings support the implementation of individualized, progressive core-focused training to optimise gait recovery and functional independence in post-stroke rehabilitation.
