There are over 40 million amputees globally with more than 185,000 Americans losing their limbs every year. For most of the world, prosthetic devices remain too expensive and uncomfortable. This paper aims to outline advancements made by a multidisciplinary research group, interested in advancing the restoration of human motion through accessible lower limb prostheses.

Customization, comfort and functionality are the most important metrics reported by prosthetists and patients. The work of this paper presents the design and manufacturing of a custom made, cost-effective and functional three-dimensional (3D) printed transtibial prosthesis monocoque design. The design of the prosthesis integrates 3D imaging, modelling and optimization techniques coupled with additive manufacturing.

The successful fabrication of a functional monocoque prosthesis through 3D printing indicates the workflow may be a solution to the worldwide accessibility crisis. The digital workflow developed in this work offers great potential for providing prosthetic devices to rural communities, which lack access to skilled prosthetic physicians. The authors found that using the workflow together with 3D printing, this study can create custom monocoque prostheses (Figure 16). These prostheses are comfortable, functional and properly aligned. In comparison with traditional prosthetic devices, the authors slowered the average cost, weight and time of production by 95%, 55% and 95%, respectively.

This novel digital design and manufacturing workflow has the potential to democratize and globally proliferate access to prosthetic devices, which restore the patient’s mobility, quality of life and health. LIMBER’s toolbox can reach places where proper prosthetic and orthotic care is not available. The digital workflow reduces the cost of making custom devices by an order of magnitude, enabling broader reach, faster access and improved comfort. This is particularly important for children who grow quickly and need new devices every few months or years, timely access is both physically and psychologically important.

In this manuscript, the authors show the application of digital design techniques for fabricating prosthetic devices. The proposed workflow implements several advantageous changes and, most importantly, digitally blends the three components of a transtibial prosthesis into a single, 3D printable monocoque device. The development of a novel unibody transtibial device that is properly aligned and adjusted digitally, greatly reduces the number of visits an amputee must make to a clinic to have a certified prosthetist adjust and modify their prosthesis. The authors believe this novel workflow has the potential to ease the worldwide accessibility crisis for prostheses.

Individuals expected to offer leadership are often chosen based on their power position within the field of interest and specialization in the context area being addressed and not on their leadership style. Leadership education curriculum often focuses on change as a product of leadership and leadership styles but places little emphasis on how the leadership styles of those chosen to lead change can influence the change process. In order to inform the development of curriculum targeting this aspect of leadership, research needs to be done to determine if leadership style impacts level of engagement in change. This research examined how transformational and transactional leadership styles impacted engagement in a national change process when 39 department chairs of universities across the United States were selected by the National Science Foundation to lead science, technology, engineering and math (STEM) educational reform at the undergraduate level. The findings revealed transformational leadership style positively predicted engagement in change and transactional leadership style negatively predicted engagement in change. While the small sample size makes the findings exploratory in nature and should be used with caution, they imply leadership education curriculum should include lessons on the impact these two styles have on engagement in change since there were statistically significant differences.

Much of the research on intimate partner violence focuses on adults, and little of it emanates from the Global-South. The study reported upon in this chapter is aimed at addressing these gaps. Adopting a Southern Feminist Framework, it discusses findings from interviews with Brasilian and Australian advocates working on prevention of youth IPV. Participants from both countries noted disturbing instances of digital coercive control among the youth with whom they work, as well as underlying factors such as gender-based discrimination that simultaneously contribute to the prevalence of such behaviors, as well as their normalization among young people. However, they also emphasized the positive role that technology can play in distributing educational programming that reaches young people where they are and circumvents conservative agendas that in some cases keep education about gender discrimination and healthy relationships out of schools.
