In the past several years, non-actuated industrial exoskeletons have become interventions to reduce the physical demands on workers and the underlying risk factors associated with repetitive manual material handling (MMH). However, more research is warranted to validate their applicability in current dynamic manufacturing or warehousing environments and effects on the trunk and leg muscles activity, energy savings and dynamic stability of the wearer. The main objective of this dissertation is to provide comprehensive biomechanical and metabolic assessments of one commercially available passive exoskeleton. This dissertation was composed of three correlated studies. The first study aimed to provide empirical evidence in support of the use of a passive occupational exoskeleton to reduce the risks of lower back problems during repetitive lifting tasks. The findings support the concerns reported in prior research in regard to increased leg activity. The second study focused on assessing lower extremity muscle fatigue responses due to the use of an occupational exoskeleton and lifting techniques using a frequency-domain-derived variable (sEMG-MDF). Findings of the second study suggest that this passive exoskeleton could be of benefit for manual material handling by not increasing physiological strain. The third study investigated the impact of the use of an occupational exoskeleton on the postural stability of a worker across three lifting techniques. The results provided inconclusive evidence on whether the worker was at a higher risk of falling based on the margin of stability criterion.
