Traditional interventions such as ankle\u2010foot orthoses and botulinum toxin address these impairments but often fail to activate the muscles involved in propulsion. Functional electrical stimulation (FES) has shown potential to enhance muscle activation and gait speed, but its effects on biomechanical parameters, particularly on step\u2010to\u2010step transitions, remain insufficiently explored.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A randomized crossover design included 18 individuals with stroke who walked with and without functional electrical stimulation (FES). Kinematic data and ground reaction forces (GRF) were recorded to evaluate step\u2010to\u2010step transitions. Outcome measures included the minimum vertical velocity (Vvmin) of the center of mass (CoM) and the force ratio (FRatio) between the back foot (Fback) and front foot (Ffront).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>FES significantly reduced the force ratio (FRatio) (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001), indicating improved force distribution toward the back foot. The minimum vertical velocity (Vvmin) of the center of mass (CoM) occurred earlier with FES (0.470\u00a0\u00b1\u00a00.032) compared with No FES (0.513\u00a0\u00b1\u00a00.033; <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001), demonstrating enhanced control of CoM redirection during gait.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>FES applied to specific lower limb muscles improved critical biomechanical gait parameters, including enhanced force distribution and better control of the center of mass (CoM). These findings suggest that FES can optimize gait mechanics, particularly during step\u2010to\u2010step transitions, and improve walking efficiency in individuals with stroke. Further research is needed to assess its long\u2010term effects and explore its integration into rehabilitation protocols.<\/jats:p><\/jats:sec><jats:sec><jats:title>Trial
