| Abstract: | Drilling is an activity carried out in both professional and domestic environments. In this context, knowing the postural strategies used by users is a challenge. The objective of this study is twofold: 1) to identify the different possible strategies for performing a piercing while characterizing them through quantitative biomechanical parameters related to the task; 2) to propose an evaluation of the ergonomic risks incurred by the users for each of the observed strategies. Thus, fourteen subjects carried out a drilling activity at two different heights and for two types of materials. The position of the gravity center projection in relation to the sustentation polygon as well as the angle between the axis connecting the two feet and the antero-posterior axis (drilling axis) were used to identify the different postural strategies. Three strategies respectively called “Inter-feet”, “Left foot” and “External strategy” and three sub-strategies were identified. Each has been characterized through the duration and the average and maximum forces applied during the drilling phase. Two of them, 0–30° and 30–60° Inter-feet strategies covered about 75% of the trials. Despite the presence of a lower score for the 30–60° and 60–90° External strategies, the ergonomic analysis through the Rapid Upper Limb Assessment revealed that regardless of the strategy used, the postures adopted presented risks of developing musculoskeletal disorders. Thus, the drilling activity must be considered with care.Relevance to industryThe identification and characterization of postural strategies is particularly interesting to better understand the organization of the drilling task and thus optimize productivity while ensuring operator safety. |
