Symmetry Function in Trans-Tibial Amputees Gait Supplied with the New Concept of Affordable Dynamic Foot Prosthesis—Case Study

Abstract

The development of modern technologies has made it much easier to regain the ability to walk after losing a lower limb. The variety of prosthetic feet available on the market allows for optimal choice and appropriate adjustment of the foot prosthesis to the trans-tibial amputee patient’s needs. Unfortunately, the best solutions are often not available to everyone due to their high prices. This study compares the gait patterns of patients using the new concept of an affordable dynamic foot with those of other commonly available but much more expensive foot prostheses. The kinematic and spatio-temporal parameters of gait obtained using the motion capture system were analyzed. For a clear picture of changes in bilateral deficits during gait for the pelvis, hip, knee, and ankle joints, the symmetry function was used. The results indicate that the new and cheaper concept of foot prostheses offers a very similar level of gait quality to that provided by more expensive and popular solutions. The authors suggest that the use of symmetry function thresholds of 10% does not work for amputees.

Data Analysis of Biomechanical Dynamic Modeling of a Prosthetic Running Blade

“…In prosthetic running blades, explicit dynamic modeling emerges as a pivotal tool, enabling a deeper understanding of the complex biomechanical interactions. This approach is particularly relevant in the context of high-impact activities such as running, where the prosthetic must not only replicate but also enhance the natural movement of the human body (Al-Fareh et al, 2023;Dardari et al, 2023;Mohd Mukhtar et al, 2023;Murawa et al, 2023;Seratiuk Flores et al, 2023;Sidhu et al, 2023). The explicit dynamic modeling of a prosthetic running blade involves simulating the real-time physical behaviors of the blade under various conditions, such as different speeds, angles of impact, and forces.…”
