Frequently, inadequate load distribution between the prosthetic device and the residual limb is the root cause of this issue. To advance our understanding of prosthetic interface fit, tools are needed to evaluate the mechanical interaction at the prosthetic interface, allowing interface designs to be evaluated and optimised.\u0000OBJECTIVES: Present a methodology report designed to facilitate comprehension of the mechanical interaction between the prosthetic interface and the residual limb. As a pilot study, this methodology is used to compare a hands-on and hands-off interface for a single transtibial prosthesis user using secondary Magnetic Resonance Imaging (MRI) data.\u0000METHODOLOGY: MRI data of the residual limb while wearing a prosthetic interface is segmented into a hard tissue and a skin surface model. These models are exported as stereolithography (STL) files. Two methods are used to analyse the interface designs. Firstly, CloudCompare software is used to compute the nearest vertex on the skin surface for every vertex on the compiled internal bony surface for both interface types. Secondly, CloudCompare software is used to compare registered skin surfaces of the residual limb while wearing the hands-on and hands-off interfaces.\u0000FINDINGS: The maximum and minimum nearest distances between the internal bony surface and skin surface were similar between interface types. However, the distribution of nearest distances was different. When comparing the skin surface while wearing both interfaces, where the fit is more compressive can be visualized. For the dataset used in this study, the classic features of a hands-on Patella Tendon Bearing interface and hands-off pressure cast interface could be identified.\u0000CONCLUSION: The methodology presented in this report may give researchers a further tool to better understand how interface designs affect the soft tissues of the residual limb.\u0000Layman's Abstract\u0000If a person loses all or part of their leg because of injury or disease, they may use a replacement limb to help them walk again. The replacement limb is attached to their remaining leg using a rigid shell and flexible liner. Sometimes, the skin, muscles, and other tissues of their remaining leg are damaged while wearing the replacement limb. Often, this is because the replacement limb fits poorly to their remaining leg. In order to design replacement limbs that do not cause injury, a better understanding of replacement limb fit is required. In this study, a method to understand how replacement limbs deform remaining limb skin, muscles, and other tissues, is presented. 3D medical images are taken of a person’s remaining leg while they wear two different types of replacement limbs.

Traditionally, cosmetic covers aimed to achieve an aesthetic and realistic appearance; through time, a fresh perspective has developed on cosmetic covers where traditional/realistic covers evolved into a custom-made product, which truly promotes the patient’s personality. The objectives of the study were to gather information from five well-known companies in the cosmetic cover industry (UNYQ, Limb-Art, Alleles, WillowWood and Aqua-Leg), analyse and compare their design elements using the Pugh matrix, and suggest a novel design using the best performing criteria of each design. The overall results of the Pugh matrix revealed the opportunity of a new design with improved design elements mainly in terms of “cover fit/aesthetics”, “ease of attachment” and “practicality”. The novel design had a vast difference in total score from the second-best design, revealing the improvement possibilities such cover design may have in the future. Although the study successfully presented a theoretical novel design, it was based on data found through literature and web resources, making the overall results of the study more objective rather than subjective. Future research is encouraged to be conducted based on a more subjective approach towards cosmetic covers.\u0000Article PDF Link: https://jps.library.utoronto.ca/index.php/cpoj/article/view/42176/32350\u0000How To Cite: Efstathiou K, McGarry A. 3D printed cosmetic covers for lower limb prosthetics.

Hence, a reassessment of the value of O&P care, and the O&P workflow process is necessary to inform an update to the value proposition and practice model for sustainability. This article reviews key factors contributing to the current state of O&P, and potential solutions involving an update in practitioner competencies, and the care delivery model (from device-centric to client-centric and values-based). Updates could be achieved by leveraging the use of digital workflows that increase efficiencies and enhance the value of clinical outcomes.

Central to this narrative is the imperative for a holistic approach, harmonizing the trinity of materials, design, and methodologies to yield optimal outcomes. This balance is especially pivotal for the overlooked yet significant segment of those with partial hand and finger differences. Historically, this demographic has been underserved, with rehabilitation and prosthetic innovations often falling short. The sheer prevalence of partial hand differences underscores the urgency of tailored solutions. Traditional fabrication methods like wet lamination have posed challenges, particularly in aligning and efficiency. The advent of additive manufacturing has been transformative. The case of designing and printing a partial finger socket for Point Designs, LLC's Point Partial finger highlights this paradigm shift. Where conventional techniques demanded hours, digital design and 3D printing have condensed the process to mere minutes, without compromising on quality. This is not merely a win in terms of time efficiency; the implications for the end users are profound, ensuring a more customized and efficient solution. The journey underscores the potential of blending technology and traditional prosthetic knowledge, pointing towards a future where prosthetics align more seamlessly with users' needs.

The interest in devices has followed the Gartner Hype Cycle as 3D printing companies and associated organizations have used popular claims about 3D printed prostheses to increase their own company’s popularity. These claims created unrealistic expectations which outran the early-stage limitations of the technology, causing disillusion. Currently, the industry is moving beyond these limitations and the field seems to be advancing at a sustainable rate.

Despite the effectiveness of peer support in improving outcomes for various chronic conditions, its impact on individuals with major limb loss remains understudied. OBJECTIVE(S): This review aims to explore the existing literature on peer support for individuals with major limb loss. Specifically, exploring how the literature defines peer support; examining its implementation, identifying outcomes measured in peer support interventions, assessing the benefits for individuals with major limb loss, and identifying barriers associated with peer support provision. STUDY DESIGN: This review followed Arksey and O’Malley’s methodological framework, analysing relevant literature to identify evidence, definitions, and key factors related to peer support for individuals with major limb loss. METHODOLOGY: A comprehensive search in January 2023 utilized databases: MEDLINE, PsychInfo, Embase, and CINAHL. After a two-phase screening process, articles meeting specific criteria were included. Thematic and descriptive numerical analyses were applied to the extracted data. FINDINGS: Twenty-two articles were reviewed. Peer support was described as an opportunity to provide education, advice, and encouragement between individuals with lived experiences. Across the two intervention-based studies investigating peer support programs, outcome measures included physical, psychological, social, and quality of life. Qualitative studies described perceived benefits as improved psychosocial well-being and the opportunity to exchange knowledge. Perceived barriers included a lack of formal training and male-dominated groups, which deterred individuals with amputation from participating. CONCLUSION: The evidence from the findings of the review sheds light on the current understanding of peer support for individuals with amputation. Due to the limited number of studies available, future research is necessary to develop and evaluate the effectiveness of peer support interventions tailored to this population. Layman's Abstract Peer support offers a supportive relationship between individuals who have shared experiences with a disease or condition. While proven to enhance outcomes for individuals with chronic diseases, its impact on individuals with limb amputations is not well understood.

The Affordable Ethylene-Vinyl Acetate Roll-On (AERO) liner was created with the aim of improving functionality and streamlining the wearing process for users. OBJECTIVE: The purpose of this study was to comprehensively assess user satisfaction, comfort, and durability of the AERO liner and compare it with the common soft Pe-Lite liner. METHODOLOGY: Fourteen individuals with transtibial amputation participated in this three-month randomized crossover trial study. The Prosthesis Evaluation Questionnaire (PEQ), Expanded Socket Comfort Score (ESCS), and liner thickness measurements were used to comprehensively compare the AERO and Pe-Lite liner. FINDINGS: The AERO liner demonstrated notable improvements in prosthetic comfort and functionality over Pe-Lite liner. After three months use, there was a significant reduction in reported frustration with the AERO liner (p=0.023, r=0.604) in the PEQ subscale. Specific aspects, such as walking with the prosthesis (p=0.030, r=0.601) and odor perception (p=0.024, d=0.579), favored the use of the AERO liner. The expanded socket comfort score (ESCS) revealed significant superiority for the AERO liner “at best” (p=0.04) and “on average” (p=0.02) after one and three months, respectively. Liner thickness analysis showed significant reductions at the mid-patellar tendon location for the AERO liner at one (0.57±0.48) and three months (0.90±0.69, p=0.01) and in the posterior region after three months (0.63±0.64, p=0.05). CONCLUSION: Our study highlights the potential advantages of the AERO liner in enhancing comfort and satisfaction. Yet, durability and thinning of the liner when compared to Pe-Lite may be a concern which may eventually affect socket fit. These findings contribute to ongoing efforts to optimize prosthetic interventions and improve the quality of life of individuals with lower limb prosthesis in resource-limited environments. Layman's Abstract Comfort and satisfaction are essential for people using prosthetics. The socket interface material, which encompasses the limb, is crucial for comfort and suspension of the prosthesis on the limb. In resource-limited environments, people mainly use an interface material called Pe-Lite in their prosthetic sockets. However, there is an ongoing debate regarding its comfort and suitability for the residual limb. We aimed to evaluate an alternative material to determine if it was more comfortable and functional than Pe-Lite for these individuals. We invited fourteen people with transtibial amputations to participate in this study. They used a traditional prosthetic design and were provided both Pe-Lite and AERO liners. We asked them about their experiences and measured the various aspects of their treatment. The results were promising. People who used the AERO liner reported much less frustration after three months.
