There is high prevalence of work related musculoskeletal disorders (MSDs) in the winegrape industry. Manual pruning of dormant vines and harvesting are highly repetitive and physically demanding jobs that are expected to expose workers to an increased risk for MSDs. The purpose of this study is to quantify risk factors associated with the development of musculoskeletal injuries to the wrist and lower back while pruning and harvesting five commonly used winegrape trellis systems. Twenty three subjects participated in two separate pruning and harvesting simulations. Subjects performed either a simulated pruning or harvesting task as wrist and trunk postures data were gathered. The results revealed significant differences among the trellis systems. Compared to the other systems, the vertical shoot positioned (VSP) was determined to be most optimal in terms of decreasing relative MSD risk, for both pruning and harvesting.
