Ergonomics in the literal sense means «The rules applied at work». In the broad sense, ergonomics is defined as « the science which studies the interactions between man and his environment and which strives to improve them ».
Ergonomics is multidisciplinary and requires knowledge from different backgrounds such as psychology, biomechanics, physiology or sociology.
To better understand, we can compare it to ergotherapy.
The occupational therapist works around everyday situations. Ergotherapy is centered on man and his health, it is regulated by the public health code. People benefit from occupational therapy with medical prescription.
The ergonomist focuses on work situations. The role of the ergonomist is to adapt the work environment to humans, to participate in the preservation of health and to improve the overall performance of the organization by taking all dimensions of work situation into consideration
