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.

Reforms in the health-care system may impact how health-care professionals perceive and enact their roles. This study aims to examine the way in which occupational therapists experience and describe their roles in municipalities after the implementation of a health reform (the Coordination Act) in Norway.

This qualitative study was designed within the perspectives of social constructivism. Data was collected through focus group interviews with 10 community-working occupational therapists. A thematic framework analysis was used to examine the participants’ experiences.

The following four themes emerged: external factors that framed and shaped the occupational therapists’ roles in municipalities; the strengths and dilemmas of the generalist; the problematic generic position and the strengths; and dilemmas of the specialist.

The study suggests that occupational therapy practitioners should identify new opportunities and adapt to health reform changes. They also need to renegotiate their roles as the health reforms require more specialized competences. Greater emphasis must be placed on the core knowledge and competences of occupational therapists to strengthen their professional identity in the municipalities.

Student satisfaction is an important indicator of educational quality in higher education institutions. Learning environment factors are assumed to play a role in determining student satisfaction. The purpose of this study is to examine the intrinsic relationships between five learning environment scales embedded within one measure; and examine the associations between each of these scales and an overall measure of education program satisfaction.

In this cross-sectional study, 175 first-year occupational therapy students in Norway completed sociodemographic information and the Course Experience Questionnaire. The data were analyzed with Pearson’s correlation coefficient r and with linear regression.

All intrinsic associations between the learning environment scales were positive. In the adjusted analysis, higher education program satisfaction was significantly associated with higher scores on “clear goals and standards,” “emphasis on independence” and “good teaching.” The final model accounted for 45.0% of the outcome variance, of which the scores on the learning environment scales contributed 41.8%.

The learning environment is vital for student satisfaction. More specifically, efforts to improve student satisfaction may include strengthening student-focused teaching, strengthening the autonomy of the students, and ensuring that the goals and standards of courses are clear and easy to understand.

This papers aims to study lattice structures in terms of geometric variables, manufacturing variables and material-based variants and their correlation with compressive behaviour for their application in a methodology for the design and development of personalized elastic therapeutic products.

Lattice samples were designed and manufactured using extrusion-based additive manufacturing technologies. Mechanical tests were carried out on lattice samples for elasticity characterization purposes. The relationships between sample stiffness and key geometric and manufacturing variables were subsequently used in the case study on the design of a pressure cushion model for validation purposes. Differentiated areas were established according to patient’s pressure map to subsequently make a correlation between the patient’s pressure needs and lattice samples stiffness.

A substantial and wide variation in lattice compressive behaviour was found depending on the key study variables. The proposed methodology made it possible to efficiently identify and adjust the pressure of the different areas of the product to adapt them to the elastic needs of the patient. In this sense, the characterization lattice samples turned out to provide an effective and flexible response to the pressure requirements.

This study provides a generalized foundation of lattice structural design and adjustable stiffness in application of pressure cushions, which can be equally applied to other designs with similar purposes. The relevance and contribution of this work lie in the proposed methodology for the design of personalized therapeutic products based on the use of individual lattice structures that function as independent customizable cells.
