Article Synopsis
- - The study investigates how effective an upper limb exoskeleton is in reducing muscle strain while performing real-life industrial construction tasks.
- - Fifteen male construction workers participated, and results showed a significant 20.2% decrease in average muscle activity when using the exoskeleton, especially in specific parts of the deltoid muscle.
- - Heart rate and metabolic levels remained unchanged, while upper arm movement was similar, suggesting that exoskeletons can effectively lower the risk of muscle strain without altering overall physical demands.
Background: Long-term work with elevated arms, or overhead work, is a risk factor for musculoskeletal complaints and disorders. Upper-limb exoskeletons are a promising tool for reducing occupational workload when working with hands above shoulder level.
Objective: The purpose of this study was to assess the effects of upper-limb exoskeleton on muscular and physical strain and perceived exertion during dynamic work at four different shoulder joint angles.
