Bridging Performance and Affordability: Advances and Challenges in Modern Prosthetic Foot Development

Abstract Prosthetic foot technology has undergone remarkable advancements, evolving from rigid, non-articulated designs such as the solid ankle cushioned heel (SACH) foot to dynamic-response, microprocessor-controlled, and bionic models that closely mimic the biomechanics of the natural ankle–foot complex. These innovations have significantly improved gait restoration, reduced energy expenditure, enhanced balance, and positively influenced psychosocial outcomes. However, accessibility remains a critical challenge: while advanced designs deliver superior therapeutic and functional benefits, their high cost and technical complexity limit availability in low- and middle-income countries (LMICs). Conversely, low-cost models such as the Jaipur Foot, Niagara Foot, and MIT prosthetic foot provide culturally adaptable and affordable solutions, though often with reduced biomechanical sophistication. This review synthesizes current knowledge on prosthetic foot classification, design principles, therapeutic outcomes, and affordability challenges. It highlights the trade-offs between performance and cost, drawing attention to global disparities in prosthetic availability and use. Emerging trends including robotics artificial intelligence, personalized and adaptive solutions sustainable materials, and 3D printing offer opportunities to bridge the gap between high performance and universal accessibility. Addressing these challenges requires interdisciplinary collaboration across engineering, clinical rehabilitation, and global health. By balancing innovation with affordability, the next generation of prosthetic foot technology has the potential to deliver equitable mobility solutions for amputees worldwide.
Keywords Prosthetic foot, energy storage and return, microprocessor-controlled prosthesis, affordability, accessibility.
