Assessments were conducted at baseline, at Week 12 and at a 6-month follow-up using the Functional Reach Test (FRT), Four-Square Step Test (FSST), 2-Minute Walk Test (2MWT), Timed Up and Go (TUG) test, and Fatigue Impact Scale (FIS).</p><p><strong>Results: </strong>At 12 weeks, both CSE and VE groups improved on FRT and 2MWT, with the CSE group also experiencing improvements on FSST, TUG, and FIS (<i>p</i> < 0.05). The SBE group showed no significant changes. At 6 months, FRT, FSST, and 2MWT improvements persisted in the VE group, while the CSE group-maintained TUG and FIS gains. The VE group had superior FRT at 6 months, while the CSE group showed greater FSST improvements at 12 weeks. The VE group exhibited greater 2MWT improvements than the CSE group at 6 months, while the CSE group had better TUG results at both timepoints. Both CSE and VE groups showed greater reductions in fatigue (FIS) than the SBE group at 6 months.</p><p><strong>Discussion: </strong>VE provide long-term benefits for balance and gait speed, while CSE enhance gait endurance and postural control during training. Both modalities contribute to long-term fatigue reduction. SBE are less effective, highlighting the need for targeted interventions such as VE and CSE for sustained improvements.</p>","PeriodicalId":19131,"journal":{"name":"Neurological Research","volume":" ","pages":"1-10"},"PeriodicalIF":1.7,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143663928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
