Examining the Impacts of Wearable Robots in Mitigating Musculoskeletal Disorders Amongst Masons
摘要
Among the existing construction trades, masonry is one the most labor-intensive, as the workers are often subjected to repetitive, fast-paced, and strenuous tasks. Masonry construction often requires prolonged assumptions of different body postures, such as lifting, bending, kneeling, and reaching. While wearable robots (such as exoskeletons) offer promising ergonomic solutions to address the physical demands of diverse tasks, understanding the impacts of exoskeleton types on masons remains limited. This study aims to evaluate the impacts of passive and active exoskeletons as interventions to alleviate work-related musculoskeletal disorders among masons. Two specific objectives are set: (1) assessing the perceived discomfort across different body parts while wearing both exoskeletons and (2) assessing the impact of active and passive exoskeletons on masons’ productivity to elucidate the potential acceptance of exoskeletons amongst masonry workers. The study involves three rounds of masonry tasks performed by participants, with and without exoskeleton support, to understand the impacts of exoskeletons on productivity and perceived discomforts. The findings reveal that working without exoskeletons results in the longest task completion time but generally lower discomfort levels. The findings further reveal active exoskeletons have a significant impact on improving productivity during masonry tasks as compared to passive exoskeletons which provide moderate relief for the lower back but introduce discomfort in other regions like the upper arm, thigh, and lower leg/foot. This study contributes to the potential of using exoskeletons for improving masons’ health and safety and sustaining the aging community of masonry workers. This study also sets precedence for human-robot integration in masonry construction.
