INTRODUCTION:
Inequities in access to assistive devices remain a major public health challenge, particularly in large universal health systems where conventional production processes are centralized, costly, and slow (1). Digital health strategies combined with additive manufacturing offer opportunities to decentralize care, personalize devices, and expand access to rehabilitation services (2). This study describes the implementation and outcomes of a digital workflow for providing assistive devices to patients treated at the Digital Health Hub of the Federal University of São Paulo, within the Brazilian Unified Health System.

METHODS:
A descriptive study was conducted based on real cases of patients assisted through digital orthoses and prostheses integrated into the public health system. The workflow included digital clinical assessment, three-dimensional scanning, virtual design, additive manufacturing, and delivery of personalized devices (3-4). Selected cases involved patients with neurological and musculoskeletal conditions requiring upper and lower limb orthoses. Data were collected on production time, device customization, clinical feasibility, and user acceptance.

RESULTS:
The digital workflow enabled the production of personalized assistive devices with reduced manufacturing time compared to conventional methods. Devices demonstrated adequate fit, functional alignment with clinical goals, and high acceptance by patients and healthcare professionals. The approach supported individualized rehabilitation needs while reducing logistical barriers commonly encountered in public health services. The integration of digital health tools facilitated communication between clinicians and engineers and allowed rapid device adjustments and follow-up.

CONCLUSIONS:
Digital health combined with additive manufacturing represents a viable and sustainable strategy to reduce inequities in access to assistive technologies within universal public health systems. The experience demonstrates the potential of locally implemented digital workflows to promote inclusion, patient-centered care, and equitable rehabilitation services without borders. This approach shows strong potential for scalability in Brazil and in other large countries with universal public health systems and significant territorial and social diversity.
