Abstract
Logistics activities involve significant risk factors for the development of work-related musculoskeletal disorders (WMSD), particularly low back pain. Exoskeletons have emerged as potential solutions to mitigate these risks. This study assesses the short-term effects of dual passive back-support exoskeletons (Auxivo and Htrius) on WMSD risk factors in logistics operations. Two workstations were evaluated using self-report ratings, postural assessment, and surface electromyography (EMG). The results indicate that both exoskeletons provided relief and support during tasks, with Htrius showing a slight advantage. Exoskeletons reduced perceived exertion, especially during trunk flexion tasks, and improved posture, particularly in tasks involving manual lifting loads at lower height levels. While variations in muscular activity were observed, the Htrius exoskeleton showed a trend of reducing lumbar muscle activity. Overall, Htrius demonstrated promise in improving workers’ comfort, safety, and efficiency, potentially reducing WMSD risk and muscular fatigue. However, individual preferences and workplace-specific characteristics should be considered when selecting exoskeleton models. Future research should explore the effects on different loads, genders, and EMG of different muscles to further enhance the understanding and application of exoskeletons in occupational contexts.
