Ergonomics can roughly be defined as the study of people in their working environment. More specifically, an ergonomist (pronounced like economist) designs or modifies the work to fit the worker, not the other way around. The goal is to eliminate discomfort and risk of injury due to work.
We frequently blame poorly designed work stations, cars, sofas and other equipment and furniture for our aches and pains. Good ergonomics, however, only solves part of the equation. Often the missing piece is how we actually use our own body. Even the very best ergonomically designed workstation is of limited value if the person using it does not use their own body well.
After assessing client or patient we advise them how they can break some habit which is going wrong and can increase their pain because of continuous strain on the soft tissue within body. If required, we ask them to check out or modify certain positions or working/living area to suit their body form.
