Radial nerve injury is comparatively a common occurrence, and recovery depends on the level of injury. While medication, rest, and surgery are among treatment regimes, orthotic splints are frequently used to manage the condition by compensating for the loss of motor power. This study aimed to modify an existing design and fabricate an adjustable dynamic hand splint utilizing locally sourced materials for the management of radial nerve palsy. The methodology included the use of Autodesk Revit software and the cast of a patient for the schematic designs and measurements. The cast was transferred to a lamination jig where it was molded with EVA foam under heat, along with epoxy resin, fiberglass, and stockinet. The resulting product fit optimally on patients with varying circumferences and could be utilized for both the left and right sides of the upper extremities. The mean maximum active flexion achieved was 98.70°, indicating the rehabilitative force generated by the device. The splint, tested on five subjects, produced an angle of extension at rest ranging from 30° to 35° with a mean of 32.6°, and maximum finger flexion reaching 100°. The findings support the splint's effectiveness in rehabilitation.
