Abstract
Knowledge of the stress-strain analysis while grapevines pruning and wine harvesting in vineyards will make a significant contribution towards reducing the risk of cumulative trauma disorders (CTD) in the upper limbs of vineyard workers. The stress-strain analysis in field and laboratory studies show that pruning grapevines and wine harvesting involves a combination of dynamic and sensorimotoric work, and also a high incidence of ergonomically undesirable postures of the trunk, the upper limbs and the head irrespective of cutting tools used. The information obtained can be applied in the ergonomic redesign of pruning tasks and pruning tools to reduce incidence of trauma.
