Innovation in Motion: Characterization of Running in a Paralympic Athlete Undergoing Adaptation to a Transradial Prosthesis Benefiting Stability and Symmetry of Movements

In paralympic athletics, the use of adaptations or prosthetics is heavily influenced by the resources available to athletes. The high cost of these adaptations, combined with limited detailed methodologies for creating personalized orthopedic devices, presents a significant challenge. This study addresses these issues by presenting the design, development, and biomechanical evaluation of a transradial prosthesis tailored for a 27-year-old female paralympic track and field athlete with an upper limb amputation. The primary objective is to optimize the athlete's performance by addressing both kinetic and kinematic factors, particularly during running and the starting position. The research outlines the comprehensive process, including the residual limb's scanning, the socket's design, and the iterative development of prosthesis prototypes using materials such as thermoplastic polyurethane (TPU) and polylactic acid (PLA). Key findings indicate improvements in shoulder alignment, enhanced balance during the starting position, and increased symmetry in plantar pressure distribution. The proposed methodology, which leverages 3D technologies, underscores the importance of ongoing analysis to monitor the athlete's adaptation to the prosthesis and its impact on her athletic performance. This approach demonstrates the potential for personalized prosthetic solutions to significantly enhance athletic outcomes in paralympic sports.
