RESUMEN
BACKGROUND: To retard shortening of finger flexors in patients with Duchenne muscular dystrophy (DMD), hand orthoses are prescribed. However, many patients do not wear the orthoses regularly. To optimize orthotic interventions, we need insight into the factors influencing compliance. OBJECTIVE: To evaluate the compliance regarding hand orthoses in an adult DMD population and to explore experiences and perceptions of DMD patients wearing orthoses, and of their caregivers. METHODS: Mixed methods observational study, combining quantitative and qualitative data from medical charts combined with qualitative semi-structured interviews using a constant comparative method and a short validated questionnaire (D-QUEST). RESULTS: 65 medical charts were analyzed. 48 patients were assessed as needing hand orthoses, of whom 37.5 % were compliant. Qualitative data analyses revealed (1) motivation: preservation of hand function; (2) barriers: discomfort and impediments; (3) facilitators: good fit and personalized wearing schedule; (4) fitting process: satisfactory, but patients do not readily seek help when barriers appear. CONCLUSIONS: Patients are motivated to wear hand orthoses, but often discontinue use because of orthosis-and disease-specific barriers. The identification of these barriers leads to practical and feasible recommendations concerning the orthoses and the fitting process, such as less rigid material, preservation of some function while wearing the orthoses, and fixed evaluation points. The findings were confirmed by the D-QUEST.
