To improve ergonomic advice and to design an optimal job rotation schedule for decreasing WMSDs, a thorough documentation of full-body musculoskeletal loading topography during occupational tasks is needed.


Introduction: To improve ergonomic advice and to design an optimal job rotation schedule for decreasing WMSDs, a thorough documentation of full-body musculoskeletal loading topography during occupational tasks is needed.

Methods: 3D motion capture, ground reaction forces and muscle activations were measured while 20 participants performed 10 occupational tasks. A validated musculoskeletal modeling workflow was used to calculate the musculoskeletal loading and the association between proxy variables i.e. joint moments and joint contact forces is evaluated.

Results: Lifting 10kg from the ground imposed the highest musculoskeletal loading on all joints compared to all other lifting tasks while lifting 10kg from hip height to shoulder height imposes the lowest musculoskeletal load. The proxies did correlate well with joint contact forces during occupational tasks with a standing upright posture.

Conclusion: The validated model and the topography of musculoskeletal loading could substantiate the design of job rotation schedules and inform ergonomic advice to avoid overloading of specific anatomical regions.
