[Objectives] To synthesize evidence on HIIT versus moderate-intensity continuous training (MICT) or routine rehabilitation in stroke survivors. [Methods] We systematically searched 8 databases (PubMed, EMBASE, CENTRAL, Web of Science, SPORTSDiscus, PsycINFO, SCOPUS, CINAHL) up to May 2025. Seventeen randomized controlled trials (RCTs; total n=1 142) met inclusion criteria: adults with stroke, device-based HIIT (≥70% HRR/VO2peak), and outcomes assessing VO2peak, 6-min walk distance (6MWD), or Berg Balance Scale (BBS). Methodological quality was evaluated using the PEDro scale. Pooled effect sizes (Hedges’ g) were calculated via random-effects models, with heterogeneity quantified by I2. [Results] HIIT significantly improved peak oxygen uptake (VO2peak) versus controls (g=0.59, 95% CI: 0.44-0.75, p<0.001; I2=16.29%). Low heterogeneity and symmetrical funnel plots supported robustness. HIIT also enhanced walking endurance (6MWD: g=0.32, 95% CI: 0.16-0.48, p<0.01; I2=30%). In contrast, no significant benefit was observed for balance function (BBS: g=0.07, 95% CI: -0.13-0.26, p=0.50; I2=0%). [Conclusions] HIIT is a safe and highly effective intervention for enhancing aerobic capacity and walking function post-stroke. Its benefits are maximized at higher intensities and longer durations but do not extend to balance improvement. Integrating HIIT into stroke rehabilitation protocols is strongly recommended to promote functional independence. |
