Effects of Back Support Exoskeletons on Perceived Exertion and Mental Workload During Simulated Tile Installation
DescriptionOccupational exoskeletons can reduce physical demands during physical activities, potentially decreasing the risk of work-related musculoskeletal disorders (WMSDs). Alternative interventions are especially needed in construction, where WMSDs remain prevalent. We investigated the effectiveness of back-support exoskeletons (BSEs) in reducing perceived exertion and mental workload during simulated tiling work (installation and grouting tasks). Eighteen participants performed these tasks, using two tile sizes (12”×12” and 12”×24”) under three intervention conditions (No BSE, Laevo Flex, and HeroWear Apex). Significant interaction effects of intervention, tile size, and/or task type revealed that perceived exertion varied depending on BSE type, tile size, and task type. Additionally, sex-dependent differences were observed, with males reporting higher frustration levels. Our results support that BSEs have potential as an intervention in tiling work. To effectively mitigate WMSD risks, though, BSEs may need to be selected based on specific task demands and individual differences to maximize their benefits and worker acceptance.
