CT: Given the multifactorial etiology for MSD and its association with individual and workplace risk factors, their reduction and prevention will require a multidisciplinary effort. The science of ergonomics, biomechanics, epidemiology, and medicine are being used to better understand the interdependence of MSD. Ergonomics (Greek ergon = work and Greek nomos = law) is the study of the problems of people in adjusting to their environment; especially the science that seeks to adapt work or working conditions to suit the worker (the study of work). Biomechanics (Greek bios = indicates life or living organism and mechanic = of or pertaining to machines or tools or acting like a machine) is the study of how the living organism performs activities (the study of how work is performed). Biomechanics uses laws of physics and engineering to describe motion of various body segments and the forces that act upon these body parts during normal daily activities. By this definition, biomechanics is a multidisciplinary science. Epidemiology (Latin epidemia = of people and ology = the study of) is the medical science that focuses on the distribution and determinants of disease frequency in human populations and the application of the study to the control of the disease. Medicine (Latin medicus = doctor or mederi = to heal) the science of diagnosing, treating, or preventing disease and other damage to the body or mind.

N: 1. “scientific study of the efficiency of people in the workplace,” coined 1950 from Greek ergon “work” + -ics. Meaning “science of wealth” is from 1792.
2. Ergonomics is a science-based discipline that brings together knowledge from other subjects such as anatomy and physiology, psychology, engineering and statistics to ensure that designs complement the strengths and abilities of people and minimise the effects of their limitations.
3. In the fields of Office Automation and Life Cycle (Informatics): The application of biological and engineering data to the design of systems, programs, and devices in order to adapt them to human requirements, to the tasks they are to perform, and to the environments in which they are to be used.
