Design and Preliminary Validation of a Lightweight Powered Exoskeleton During Level Walking for Persons With Paraplegia

Multidisciplinary collaboration on exoskeleton development adopting user-centered design: a systematic integrative review

Purpose: The world population is ageing, along with an increasing possibility of functional limitations that affect independent living. Assistive technologies such as exoskeletons for rehabilitative purposes and daily activities assistance maintaining the independence of people with disabilities, especially older adults who wish to ageing-in-place. The purpose of this systematic integrative review was threefold: to explore the development team compositions and involvement, to understand the recruitment and engagement of stakeholders, and to synthesise reported or anticipated consequences of multidisciplinary collaboration.Methods: Databases searched included PubMed, CINAHL Plus, PsycINFO, Web of Science, Scopus, and IEEE Xplore. A total of 34 studies that reported the development of exoskeleton adopting user-centered design (UCD) method in healthcare or community settings that were published in English from 2000 to July 2022 were included.Results: Three major trends emerged from the analysis of included studies. First, there is a need to redefine multidisciplinary collaboration, from within-discipline collaboration to cross-discipline collaboration. Second, the level of engagement of stakeholders during the exoskeleton development remained low. Third, there was no standardised measurement to quantify knowledge production currently.Conclusion: As suggested by the synthesised results in this review, exoskeleton development has been increasing to improve the functioning of people with disabilities. Exoskeleton development often required expertise from different disciplines and the involvement of stakeholders to increase acceptance, thus we propose the Multidisciplinary Collaboration Appraisal Tool to assess multidisciplinary collaboration using the UCD approach. Future research is required to understand the effectiveness of multidisciplinary collaboration on exoskeleton development using the UCD approach.IMPLICATIONS FOR REHABILITATIONGlobal trend of population ageing causes a higher risk of disability in older adults who require rehabilitation and assistance in daily living.Assistive technologies such as exoskeletons have the potential to contribute to rehabilitation training and daily activity assistance demand closer multidisciplinary collaboration.A Multidisciplinary Collaboration Appraisal Tool using user-centered design approach (MCAT) is proposed to understand the effectiveness as well as limitations and barriers associated with multidisciplinary collaboration in developing exoskeletons.

Process management of ergonomic workplace based on augmented reality principles

Ergonomics is an important element of managing performance and productivity in a company. Nowadays, the ergonomic parameters are set in line with the implementation of the Industry 4.0 concept. The paper highlights the link between virtual reality (VR) and augmented reality (AR), when combined with the traditional ergonomic procedure.  Automation and digitization contribute to a significant extent to the creation of ergonomic workplaces and the elimination of the negative effects of non-ergonomic workplaces on people. The aim of the paper is to determine the essential elements of the system process approach to ergonomics management. This is achieved through an analysis of the current approaches from Industry 4.0 and a focus on the augmented reality approach. The backbone of the triple combination of "man-machine-environment" determines the ergonomic setting of work and the workplace. Subsequently, the presented case study examines the link between ergonomic workplace principles and data analytics for VR/AR technology. The scientific contribution of the paper lies in the discussion of the case study results, which is beneficial for the ergonomic design of workplaces.
