Background and Objective:
Dynamic response prosthetic feet enhance gait efficiency and quality of life compared to traditional designs like the SACH foot but remain understudied in resource-limited settings. This systematic review aims to evaluate the design technology, material applications, and clinical impacts of dynamic response prosthetic feet in transtibial amputee rehabilitation, emphasizing cost-effective, sustainable solutions for developing countries.
Methods: A systematic literature search was conducted using PubMed, Google Scholar, Scopus, and Research Network for studies from January 2010 to March 2023. Search terms included “dynamic response prosthetic foot,” “transtibial amputee,” and “gait analysis.” Inclusion criteria comprised peer-reviewed studies in English assessing biomechanical performance, materials, or clinical outcomes in transtibial amputees. Of 162 articles, 43 were included after screening titles, abstracts, and full texts. Data extraction focused on prosthetic design, materials (e.g., carbon fiber, polypropylene-kenaf), gait parameters, and energy expenditure (Physiological Cost Index [PCI]). The Joanna Briggs Institute tools assessed study quality. Narrative synthesis was used due to heterogeneity in study designs.
Results: The 43 studies (25 experimental, 12 observational, 6 reviews) involved over 1,200 amputees and 500 controls. Dynamic response feet improved stride length (12%-18%; P<.001), walking speed (20%-23%; P<.001), and cadence (15%-20%; P<.01) compared to SACH feet.4 PCI was reduced by 9%-15% (0.68 vs 0.75 beats/m; P<.001), nearing high-end designs.5,6 Polypropylene-kenaf composites showed comparable performance to carbon fiber, enhancing affordability.7 However, gait asymmetry persisted, with longer stride times (2.47 vs 1.11 s; P<.05) and lower prosthetic limb ground reaction forces (52.3% vs 107.5% body weight; P<.05).
Conclusion: Dynamic response prosthetic feet significantly improve gait and energy efficiency, with sustainable materials like polypropylene-kenaf offering viable solutions for developing countries. Persistent gait asymmetry and study limitations underscore the need for larger, longitudinal trials to optimize designs and ensure durability.
