Effects of 24-weeks in-field use of a back-supporting exoskeleton on biomechanics, work intensity and musculoskeletal discomfort: A randomized controlled trial among logistic workers
The trial investigated the impact of a back-supporting exoskeleton (BSE) on biomechanics, work intensity, and musculoskeletal discomfort among logistic-workers over 24-weeks in a field-setting. Twenty workers were randomized into intervention and control groups, performing daily order-picking with and without the BSE, respectively. Effects on muscles activity and kinematics were measured during standardized tasks before and after the intervention period, while work intensity and musculoskeletal discomfort were rated throughout the intervention period. The results indicated significant reductions in back muscle activity during lifting tasks with BSE assistance before and after 24-weeks. Although three BSE users stopped using the exoskeleton during the intervention period, the remaining workers progressively increased their daily BSE use associated with an overall decrease in perceived work intensity throughout the 24-weeks. The trial suggests that the effect of the BSE on back muscle activity remains constant over 24-weeks, opposite what was hypothesized based on previous research on training.
