Development and assessment of the e-Seating app as a tool for prescribing wheelchairs and postural support devices: a qualitative study

Abstract

Introduction: e-Seating is a mobile application developed to assist rehabilitation professionals in decision-making during the prescription of wheelchairs and postural support devices (WPSD). The app provides a structured assessment protocol, aligns with the stages of the prescription process, integrates relevant information, and generates technical reports. Objective: To describe the development and evaluation process of the e-Seating application. Method: This qualitative, exploratory, and descriptive study was conducted in three phases, involving 91 participants, including occupational therapists, physical therapists, physiatrists, technicians, wheelchair users, and technology specialists. In phase 1, challenges related to WPSD assessment and prescription were identified, informing the development of the initial prototype. In phase 2, the app was tested and refined based on feedback collected through four iterative versions. In phase 3, technology experts assessed the app’s usability. Data collection methods included semistructured interviews, focus groups, and heuristic evaluations. Data analysis followed a qualitative approach. Results: Phase 1 revealed a lack of systematization in WPSD assessment and prescription, communication gaps between professionals and technicians, and limited user participation. In phase 2, feedback from rehabilitation professionals contributed to improvements in each app version. In phase 3, usability testing informed refinements to the app’s technical and functional features. Conclusion: The study led to the development of a structured framework for WPSD assessment and prescription, offering comprehensive support throughout the prescription process.
