“…Especially in tasks that involved hip flexion or trunk flexion, objective performance decreased and perceived task difficulty increased. This problem of restricted range of motion can be found in all studies that asked for subjective feedback on passive lifting devices (Abdoli-E, Agnew and Stevenson, 2006;Godwin et al, 2009;Graham et al, 2009). Godwin et al (2009) reported moderate ratings of hindered ROM when wearing the device.…”

Godwin et al (2009) reported moderate ratings of hindered ROM when wearing the device. This can be compared to our results on user impression which scored between 3.1 and 5.9 for restriction of range of motion (see Table 2).…”

The effect of a passive trunk exoskeleton on functional performance in healthy individuals

et al. 2018

View full text Add to dashboard Cite

The objective of this study was to assess the effect of a passive trunk exoskeleton on functional performance for various work related tasks in healthy individuals. 18 healthy men performed 12 tasks. Functional performance in each task was assessed based on objective outcome measures and subjectively in terms of perceived task difficulty, local and general discomfort. Wearing the exoskeleton tended to increase objective performance in static forward bending, but decreased performance in tasks, such as walking, carrying and ladder climbing. A significant decrease was found in perceived task difficulty and local discomfort in the back in static forward bending, but a significant increase of perceived difficulty in several other tasks, like walking, squatting and wide standing. Especially tasks that involved hip flexion were perceived more difficult with the exoskeleton. Design improvements should include provisions to allow full range of motion of hips and trunk to increase versatility and user acceptance.

“…Once they are introduced, the performance of a certain task is then either slower or faster. The main reasons for performance slowdowns are restrictions of motion [35,36]. By using exoskeletons for better precision [33] and high flexibility, faster movements are possible as well.…”

This article presents a holistic methodology for planning, optimization and integration of exoskeletons for human-centered workplaces, with a focus on the automotive industry. Parts of current and future challenges in this industry (i.e., need of flexible manufacturing but as well having demographic change) are the motivation for this article. This challenges should be transformed in positive effectiveness by integrating of exoskeletons regarding this article. Already published research work from authors are combined in a form of summary, to get all relevant knowledge, and especially results, in a coherent and final context. This article gives interested newcomers, as well as experienced users, planners and researchers, in exoskeleton technology an overview and guideline of all relevant parts: from absolute basics beginning until operative usage. After fixing the motivation with resulting three relevant research questions, an introduction to the exoskeleton technology and to the current challenges in planning and optimizing the ergonomics and efficiency in manufacturing are given. A first preselection method (called ExoMatch) is presented to find the most suitable exoskeleton for workplacesm by filtering and matching all the important analyzed attributes and characteristics under consideration to all relevant aspects from environments. The next section treats results regarding an analysis of influencing factors by integrating exoskeletons in manufacturing. In particular, ergonomic-related and production-process-related (especially time-management) influences identified and researched in already published works are discussed. The next important step is to present a roadmap as a guideline for integration exoskeleton. This article gives relevant knowledge, methodologies and guidelines for optimized integrating exoskeleton for human-centered workplaces, under consideration of ergonomics- and process-related influences, in a coherent context, as a result and summary from several already published research work.

“…Examples include reports by Barrett and Fathallah (2001), Yamamoto, Hyodo, Ishii, and Matsuo (2002), Kobayashi, Suzuki, Nozaki, and Tsuji (2007), Naito, Obinata, Nakayama, and Hase (2007), Kobayashi and Nozaki (2008), Rashedi, Kim, Nussbaum, and Agnew (2014), and Sylla, Bonnet, Colledani, and Fraisse (2014). Especially notable was a set of papers that assessed the "Personal Lift Augmentation Device" or PLAD (Abdoli-E, Agnew, & Stevenson, 2006;Abdoli-E & Stevenson, 2008;Frost, Abdoli-E, & Stevenson, 2009;Godwin et al, 2009;Graham, Agnew, & Stevenson, 2009;Graham, Smallman, Sadler, & Stevenson, 2013;Graham, Smallman, Miller, & Stevenson, 2015;Whitfield, Costigan, Stevenson, & Smallman, 2014). As a whole, these early papers laid the groundwork for future efforts in two areas.…”
