As we know, winter pruning is one of the critical points in the management of the vineyard. In small farms, often located in slope areas, winter pruning is mainly performed manually. From studies carried out on vineyards from Sicily and Lombardy region, pruning operated with conventional scissors remain the most widely used method. The use of pre-pruning machine is a very good solution to facilitate the subsequent manual intervention. In every case, winter pruning require manual operations carried out by secateurs or, less commonly, by long handle shears. Recent works, conducted to assess through OCRA Index the muscle – skeletal risk due to manual pruning of the vineyard, showed a variability in the forces applied on the scissors. The purpose of this work is to verify the forces exerted on the scissors by different regions of the hand during the pruning of the vineyard. So we used a conventional scissors equipped with sensors able to detect the force exerted and the duration of the effort. The tests were conducted in the laboratory and the results were processed with the aim to show if the hand forces during manual cutting are function of diameters and cultivated varieties.

Abstract
As we know, winter pruning is one of the critical points in the management of the vineyard. In small farms, often located in slope areas, winter pruning is mainly performed manually. From studies carried out on vineyards from Sicily and Lombardy region, pruning operated with conventional scissors remain the most widely used method. The use of pre-pruning machine is a very good solution to facilitate the subsequent manual intervention. In every case, winter pruning require manual operations carried out by secateurs or, less commonly, by long handle shears. Recent works, conducted to assess through OCRA Index the muscle – skeletal risk due to manual pruning of the vineyard, showed a variability in the forces applied on the scissors. The purpose of this work is to verify the forces exerted on the scissors by different regions of the hand during the pruning of the vineyard. So we used a conventional scissors equipped with sensors able to detect the force exerted and the duration of the effort. The tests were conducted in the laboratory and the results were processed with the aim to show if the hand forces during manual cutting are function of diameters and cultivated varieties.File | Dimensione | Formato | |
