This review seeks to address this gap. Online databases (CINAHL, Embase, Scopus, PubMed, Cochrane Reviews, Web of Science, and Google Scholar) were searched without time limitation till 2024. Studies were included if they addressed hand orthoses satisfaction and adherence. Data were extracted on factors affecting satisfaction and adherence related to hand orthoses. A thematic analysis approach was employed to develop and refine a comprehensive informal checklist through expert panel consultation. After eligibility screening, we included 20 papers published between 2000 and 2023. The review identified vital orthoses-related factors for custom-made orthoses, such as comfort, durability, and fit. For 3D-printed orthoses, factors like precision, printing efficiency, and safety were highlighted, affecting adherence to orthoses use. In addition, expert consultations contributed significantly, adding factors such as initial strength and surface smoothness for custom-made orthoses, ease of readjusting, design freedom, and environmental impact for 3D-printed orthoses. Two final checklists for patients and therapists were developed based on all extracted factors, which furthered our understanding of factors influencing orthoses adherence. This review highlights the significant orthoses-related factors impacting patient satisfaction and adherence. The derived checklists are beneficial tools for therapists and patients to ensure orthoses adherence, aiming for improved therapeutic results.</p>","PeriodicalId":49657,"journal":{"name":"Prosthetics and Orthotics International","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144217378","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}
