RULA (Rapid Upper Limb Assessment) Methodology for Ergonomics Using Inertial Sensors

Nowadays different studies have shown that workers in different areas such as the field of construction, manufacturing and others, can be affected by muscle and musculoskeletal problems caused by poor posture during working hours, which is why different methods have been developed for the prevention of this type of problems in the health of workers. One of these methods is RULA (Rapid Upper Limb Assessment) which allows us to quickly evaluate the posture and thus categorize the risk factors by means of a score with which a certain level of action is established and based on it indicate if the posture is acceptable or if it is necessary to make any changes. In this work, inertial sensors were used to obtain the values of the angles formed by the limbs and thus determine the score in each of them.
