Exploring Effects of Shoulder-Assist Exoskeletons on Load-Carrying Stability: A Phase-Specific Approach

Manual material handling (MMH), a common task in occupational settings that frequently requires workers to transition immediately from lifting to short-distance load-carrying, is associated with a high risk of musculoskeletal injuries. Although commercial exoskeletons have shown potential to reduce local physical workl...

Subject-Specific Predictive Musculoskeletal Simulations of Lower-Limb Exoskeleton Assistance: Metabolic and Biomechanical Effects of Joint Assistance Strategies

Lower-limb exoskeletons have made considerable progress in reducing energy expenditure during walking. However, designing optimal assistance strategies remains challenging, particularly given inter-individual variability in anthropometry and biomechanics. This study explores energy-optimal lower-limb joint-assistance s...
