“…The applied peak load also varied among the studies. Some studies loaded feet to a maximum of 1,500 N ( 4 , 37 ), while some went up to 3,500 N ( 4 ). Most manufacturers do not report standardized technical specifications for their prostheses, making objective distinction challenging ( 10 ).…”

BackgroundAlthough mechanical properties of running specific prostheses (RSPs) can affect running performance, manufacturers do not consistently report them. This study aimed to review existing literature on RSP mechanical and structural properties and their relationship with running performance.MethodsA comprehensive search was conducted using keywords related to mechanical properties of RSPs and running performance. Search terms included stiffness and hysteresis, as well as performance outcomes including metabolic cost and running speed. Non-peer-reviewed and non-English publications were excluded.ResultsTwenty articles were included in the review. Sixteen studies used a material testing machine to measure RSP material properties, and four articles used other techniques including 2D/3D video capture and force platforms. Both measurement techniques and reporting of outcomes were inconsistent, which limits the ability to draw broad conclusions. Additionally, several studies did not report the numerical data for material properties despite measuring them. Relatively few articles measured both material properties and running performance and assessed correlations.ConclusionSeveral articles connected prosthesis properties to running performance. However, inconsistent measurement and reporting of mechanical properties, along with the multifactorial nature of the athlete-prosthesis system, limit the ability to draw broad conclusions regarding the relationship between material and structural properties and athlete performance. Current evidence may be useful for clinicians seeking ways to optimize RSP stiffness in a case-by-case basis; however, clinicians would benefit from more consistent and systematic comparisons of the attributes of different RSPs and their role in performance.

“…Between 110 million and 190 million people living in developing nations were estimated to have impairments in 2015, with more than 90 million of those people being children (Sundararaj and Subramaniyan, 2020). By 2025, it is expected that more than 25 million people worldwide would need orthotic or prosthetic devices (Abood and Faidh-Allah, 2019;Solis et al, 2021;Talla et al, 2021). The demand would still be great now.…”

Prosthetic running blades offer a solution for individuals with disabilities to engage in sports, benefiting them both psychologically and physiologically. Furthermore, a good prosthetic running blade in terms of performance and cost is rarely available to all disabled persons. In this study, we have examined how various materials impact the static behavior of the prosthetic running blade. A finite element numerical analysis was conducted on a prosthetic design to investigate this effect. We have used different materials for investigation such as aluminum alloy (2024 T4), stainless steel (AISI 316), carbon fiber, and titanium alloy (grade 5), under different load conditions. The load conditions have been varied mainly to three conditions, namely, rest (700 N), walking (1400 N), and running (2100 N). In our experimental design, we studied total deformation, equivalent stress, and strain energy to understand the performance based on material choice. It was noticed that the aluminum alloy (2024 T4) blade goes under much deformation when compared to titanium- and carbon fiber-made running blades. The least amount of overall deformation occurs in carbon fiber under varying load conditions. Carbon fiber appears to be the most profitable option due to its lowest cost per running blade. Titanium alloy grade 5, carbon fiber, AISI 316 stainless steel, and aluminum 2024 T4 alloy cost a total of 78.1, 48.5, 67.6, and 20.9 USD, respectively. It is evident that titanium alloy materials carry a higher price compared to alternative materials.

“…In 2015, it was predicted that between 110 million and 190 million individuals living in developing countries have impairments, with more than 90 million of them being adolescents (Sundararaj and Subramaniyan, 2020). Based on these prevalence estimates, approximately 25 million people require prosthetic lower-limb devices globally (Thyssenkrupp, 2018;Abood and Faidh-Allah, 2019;Solis et al, 2021;Talla et al, 2021). Human limb amputation causes enormous changes in the physiological and psychological conditions of a disabled person.…”

The amputation of a lower limb for humans is one of the most traumatic experiences, both physically and emotionally. Prosthetic running blades provide disabled persons with an opportunity to participate in sports and thus help to improve their psychological health. They also allow them to participate in activities that were previously unavailable to them due to financial constraints. In the current study, we looked at how different materials affected the functionality of prosthetic running blades. We investigated the static behavior of a prosthetic running blade using finite element modeling. Under various load circumstances, we conducted numerical simulation using a variety of materials, including titanium alloy (grade 5), carbon fiber, stainless steel (AISI 316), and aluminum alloy (2024 T4). We studied three major load conditions: rest (700 N), walking (1400 N), and running (2200 N). To understand the performance depending on the selection of materials, we evaluated total deformation, equivalent stress, and strain energy in the design of our experiment. The titanium alloy is more durable and has a higher tensile strength. The high cost of manufacture for titanium alloy, however, is a major deterrent to its use in running blades. It was noticed that the aluminum alloy (2024 T4) blade goes under much deformation as compared to titanium and carbon fiber-made running blades. Furthermore, carbon fibers offer excellent mechanical properties, which are essential for creating running blades. It has outstanding tensile properties. Additionally, the low density of carbon fiber has the added advantage of making running blades lighter.
