Impact of 3D-Printed Technology on Functional Performance in an Individual with C2 Spinal Cord Injury: A Case Report

This case report describes the use of a 3D-printed wheelchair joystick to improve functional performance in an individual with incomplete traumatic spinal cord injury at C2. A 29-year-old man presented with complete tetraplegia and no residual upper extremity function following a traffic accident, rendering him unable to operate manual or electric wheelchairs. To address this limitation, a joystick adapted for residual shoulder movements was developed using fused deposition modeling with polylactic acid material. After training, the patient achieved proficiency in maneuvering the wheelchair, as assessed with the Functional Independence Measure, enabling safe navigation and increased engagement in daily activities. This case illustrates how 3D-printed assistive devices can enhance functional autonomy and community participation in individuals with high cervical spinal cord injury.
