The ongoing automation of industrial processes has as an effect the adoption of machines in order to implement tasks that were traditionally accomplished by humans. However, in some tasks that require high precision and adaptability humans still prove to be more efficient than machines [1]. The downside of this is that humans can get injured especially when the task is lengthy and requires the use of tools of substantial weight. Studies that have been done in the automotive industry have shown that workers that work for many hours with heavy loads over their head tend to get injured mostly in the shoulders and lower back area [2]. These injuries except of the harm on the health of the workers lead to loss of productivity since workers need several days per year to rehabilitate. This phenomenon has lead big automotive companies to invest on exoskeletons to aid their workers.The aim of this study is to assess the effect an exoskeleton has on the muscular activity of the deltoid muscles while the user is performing a task simulating a real life situation
