| Abstract | Purpose: Equilibrium and mobility are interdependent phenomena critical to effective body maneuver tracking in prosthetic and orthotic (P&O) devices. Equilibrium necessitates a summative force analysis to achieve a functional resultant, particularly in P&O design. This study and related literature focus on min-imizing energy expenditure through the specific design of customized hip and knee joint geometries. Methods: This case study involves a 7-year-old boy with congenital hemimelia, characterized by the ab-sence of the right lower limb from the hip joint, a malformed left hip joint with a pseudo knee joint slightly below it, and an internally rotated foot below the knee. The objective was to develop a simple prosthetic device to facilitate ambulation with minimal energy expenditure. Results: The prosthetic device incorporated an alternating hip joint with elastic actuators, coordinated with a customized knee joint and a nipping foot unit, enabling dynamic gait. Gait function was analyzed using differential calculus, assessing the dynamic stability factor of the control object. Conclusion: The patient successfully ambulated without strain, demonstrating the efficacy of the device. Gait parameters can be optimized by adjusting the elastic spring actuators, suggesting potential for further refinement. |
