Abstract：Objective To develop a systematic and scientific assessment-adaptation-evaluation framework for wheelchair cushions.
Methods A mixed-methods approach integrating literature review,qualitative interviews and Delphi expert consultation was employed.First,27 relevant studies were identified through systematic literature searches,comprehensively synthesizing wheelchair cushion types,performance indicators,key assessment/adaptation elements and evalua-tion methods.Second,semi-structured interviews were conducted with 24 wheelchair users and six assistive tech-nology specialists.Interview transcripts were analyzed using Colaizzi's phenomenological analysis to extract themes and deeply explore user needs and practitioner experiences.Based on the literature and interview find-ings,the research team developed a preliminary protocol comprising an assessment form,an adaptation process table and an effectiveness evaluation form.Finally,20 multidisciplinary experts participated in a two-round Del-phi consultation.Experts rated the importance of items using a 5-point Likert scale.Consensus was analyzed us-ing Kendall's W coefficient and the coefficient of variation(CV),supplemented by mean importance scores and full-score frequency to refine the protocol.
Results The consultation demonstrated excellent expert engagement(100%response rate)and strong authority(Cr=0.90).The finalized protocol comprised of an assessment form(four primary domains/21 secondary items),an ad-aptation protocol(two primary domains/eight secondary items)and an evaluation form(two primary domains/15 secondary items).Statistical analysis revealed Kendall's W=0.20(P<0.05),mean importance scores of(4.48±0.72),CV=(0.15±0.05),and full-score frequency of(60.80±16.39)%,indicating acceptable consensus.
Conclusion The assessment-adaptation-evaluation method for wheelchair cushions constructed in this study is scientific,comprehensive and operable,and can provide a standardized tool for clinical personalized adaptation.Future studies should enhance the applicability of the method in diverse clinical settings.
