“…An exoskeleton system represents a common form of interaction between humans and machines [17], and has two forms: powered and passive. Powered exoskeletons are mostly still restricted to laboratory research due to their higher costs and greater complexity.…”

Manual material handling (MMH) significantly impacts worker health and productivity, often leading to musculoskeletal disorders (MSDs) primarily in the lower back. As a novel assistive technology, exoskeletons may serve as ergonomic tools to mitigate these work-related MSDs. It is essential to examine exoskeletons from the users’ perspectives before their widespread implementation in occupational settings. This study investigates the effectiveness of a passive back-support exoskeleton (BExo) in reducing perceived physical exertion and improving ergonomic safety in manufacturing context. Twenty-two college students were recruited to perform MMH tasks in a controlled lab environment, both with and without the BExo, followed by completing a survey questionnaire on various aspects of the BExo. Using ANOVA, the study analyzed biomechanical exertion across various body parts and tasks. The findings indicate that the BExo substantially alleviates discomfort in the low back, shoulders and knees, thereby, enhancing ergonomic posture and reducing fatigue. These results underscore the potential of passive exoskeletons to boost workers’ safety and efficiency, providing valuable insights for future ergonomic strategies in industrial setting.

Exoskeletons, wearable devices designed to enhance physical activity, show promise in mitigating work-related musculoskeletal disorders and injuries. This study examines exoskeleton efficacy as ergonomic intervention for aiding injured workers with limited trunk mobility in returning to work. Six adult males participated in simulated bending tasks using a trunk mobility restrictor and a passive trunk exoskeleton. Lumbosacral joint loads and moments during bending tasks with and without the exoskeleton were biomechanically assessed using optical motion capture and ground reaction force data as model inputs. Results indicate significant reductions in compressive loads and subject moments at the lumbosacral joint with exoskeleton usage, particularly during full bending. Moreover, the exoskeleton’s supportive impact increases with greater trunk flexion angles. These findings underscore exoskeleton potential in facilitating the return to work for individuals with limited trunk mobility, emphasizing the need for further empirical validation in real-world settings.

The issue of work-related musculoskeletal disorders (WMSDs) stemming from manual handling tasks remains a significant economic and societal burden, with healthcare workers being one of the most persistently affected groups. Exoskeletons have seen growing implementation for aiding manual handling tasks in industrial sectors. Traditional measurements and analyses of joint kinematics and dynamics commonly utilize optical motion capture systems and force plates. Nevertheless, the limitations of optical motion capture systems include their dependence on marker visibility and the necessity for a controlled lab environment. An innovative wireless technology featuring miniaturized, skin-mounted sensors, BioStamp nPoint (MC10, Inc., MA, USA) exhibits significant potential in addressing the challenges mentioned above. Therefore, the objective of this study was to explore a flexible sensor-based approach to assessing the effects of a back exoskeleton on joint kinematics during patient handling.
