Background: The global demand for assistive devices, such as prosthetics and orthotics, is increasing. A shortage of trained professionals contributes to suboptimal care. To improve clinical workflows, the Life Lounge Clinical Workflow (LLCW) has been developed. Understanding user acceptance is essential for ensuring its successful implementation. Objective: This study explored prosthetists and orthotists professionals’ perceptions and acceptance of LLCW, as well as the perceived benefits and challenges associated with its use. Methods: A postdemonstration mixed methods study was conducted using the unified theory of acceptance and use of technology framework, combining Likert-scale summaries with thematic analysis of open-text responses. The study included 18 prosthetists and orthotists professionals working at orthotic and prosthetic clinics across Sweden. After an interactive session about LLCW, feedback was collected via questionnaires. Thematic analysis was used to analyze the data. Results: Participants rated several acceptance-related constructs positively. Performance expectancy and facilitating conditions emerged as the most favorably discussed areas in the qualitative responses. Descriptive ratings showed high mean scores for motivation to use (4.61), management encouragement (4.56), ease of use (4.11), and willingness to use voluntarily (4.11). However, colleagues’ perceptions had a lower mean rating (2.72). Participants highlighted centralized data access, reduced administrative tasks, and improved clinical preparation as key benefits. At the same time, concerns were raised regarding data accuracy, questionnaire length, and the need for structured training before implementation. Conclusions: Participants reported generally positive experiences with LLCW, particularly regarding usability and performance. However, successful implementation requires integration into existing clinical workflows and attention to training and patient engagement. Addressing these elements can support broader adoption and contribute to digital transformation in prosthetics and orthotics care.
