However, the differential effects of spatial versus temporal verbal instructions on spatiotemporal gait parameters remain poorly understood. Verbal instructions may also be understood as a modulation of attentional focus that engages distinct neural control strategies.To investigate the effects of spatial and temporal pre-verbal prioritized instructions on spatiotemporal gait parameters compared with a no-prioritization condition in stroke patients.Twenty-seven stroke patients walked under three randomized conditions: no prioritization, spatial prioritization (matching step length equally), and temporal prioritization (rhythmic counting aloud to match step timing equally). Spatiotemporal gait parameters were measured using the GAITRite® system. Repeated-measures ANOVA was used for primary analysis, with velocity-adjusted ANCOVA used to examine whether symmetry changes were independent of gait velocity.Significant main effects were found for velocity (F(2,52) = 13.917, <italic>p</italic> < .001), step time difference (F(2,52) = 5.463, <italic>p</italic> = .007), step time of less affected side (F(2,52) = 9.108, <italic>p</italic> < .001), step length of affected side (F(2,52) = 14.531, <italic>p</italic> < .001), and step length of less affected side (F(2,52) = 9.892, <italic>p</italic> < .001). Temporal prioritization produced significantly greater reduction in step time difference compared with both spatial prioritization and no prioritization, while producing less velocity reduction than spatial prioritization. Velocity-adjusted ANCOVA indicated that the step time difference effect remained significant after controlling for gait velocity (F(1,51) = 5.785, <italic>p</italic> = .020).Temporal prioritization instruction acutely produced greater temporal gait symmetry improvement with less velocity reduction compared with spatial prioritization. Clinicians may consider temporal verbal cues as a potential strategy to address temporal gait asymmetry, though longitudinal studies are needed to determine retention and motor learning effects. pubtype: Academic Journal doctype: Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
