Ergonomics has managed to acquire the title of "science", as in recent years its methodology and research have been increasingly improved and documented, demonstrating the correct ways and applications of various human activities and tasks, with the main focus being the physical safety and productivity of individuals.
Ergonomics collaborates for this reason with other humanitarian sciences, such as Medicine and Physical Therapy, through two-way exchange of observations-applications and methods of preventing physical strains.
Therefore, it is considered appropriate to teach the basic principles of ergonomics, through which we will be led to thoughts and actions for more effective prevention of physical disorders and strains arising from occupational employment. (from the author's preface)
