Rapid Orthotics for CURE Kenya - Mechanical Design and Official Testing of 3D Printed Sockets

Rapid Orthotics for Cure Kenya (ROCK) collaborates with CURE, a non-profit orthopedic workshop in Kjabe, Kenya, to implement a 3D printing system for manufacturing custom prosthetics and orthotics. The goal is to reduce the production time and cost for the current transtibial sockets being manufactured in the orthotic workshop to give the patients a way to integrate into society and reduce stigma from their communities. The team designed a system for manufacturing transtibial sockets by converting a scan of the residual limb to a digital file customized by the orthopedic technicians and converted to a file to be 3D printed. The team designed a procedure to ensure the safety of the sockets within the constraints and offsets of the ISO 10328 Standard. The standard requires twelve official tests specifying the type and conditions to be conducted for the Ultimate Strength and Static Proof tests. The team has designed a testing rig that interfaces with the Materials Testing System machine at Messiah University to apply the necessary forces according to the complex geometry outlined in the standard. Additionally, research has determined the optimized 3D printing settings to increase the quality and consistency of the sockets. To smoothly institute the system developed in the orthopedic workshop, the team has developed a Training Manual outlining the step-by-step procedure for the system. Using this system, the team completed all twelve tests with a passing socket result which will contribute to determining the steps for next semester and for the summer site team trip.

Prosthetic Knee for CURE Kenya: Design and Manufacturing

The Prosthetic Knee team is partnered with the CURE International Hospital in Kijabe, Kenya. In the region surrounding our client’s facility, there is a large number of lower-extremity amputations due to various infections and diseases. Often, these patients choose to undergo a more invasive transfemoral amputation to enable them to use a less expensive above-knee prosthesis. The goal of the project is to present the orthopedic workshop at CURE with a manufacturable prosthetic knee design in May of 2023 that provides through-knee amputee patients with a more affordable, aesthetically pleasing, and lightweight prosthetic option, thereby removing the need to undergo an additional amputation above the knee. The poster presents the overarching elements of the prosthetic design in addition to the recently integrated locking and damping components, which aid in the functionality of the knee.

The Human Affectome

Over the last decades, the interdisciplinary field of the affective sciences has seen proliferation rather than integration of theoretical perspectives. This is due to differences in metaphysical and mechanistic assumptions about human affective phenomena (what they are and how they work) which, shaped by academic motivations and values, have determined the affective constructs and operationalizations. An assumption on the purpose of affective phenomenacan be used as a teleological principle to guide the construction of a common set of metaphysical and mechanistic assumptions—a framework for human affective research. In this capstone paper for the special issue “Towards an Integrated Understanding of the Human Affectome”, we gather the tiered purpose of human affective phenomena to synthesize assumptions that account for human affective phenomenacollectively. This teleologically-grounded framework offers a principled agenda and launchpad for both organizing existing perspectives and generating new ones. Ultimately, we hope Human Affectome brings us a step closer to not only an integrated understanding of human affective phenomena, but an integrated field for affective research
