Lately this blog has focused on safety, time to get back on to straight ergonomics. One of the challenges for people interested is what is ergonomically correct. You see it in a lot of places. Car sets and controls are ergonomically designed? What does that mean? Didn't they think of drivers before? Anyway, ergonomics focuses on risk factors.
The language of ergonomics is not the medicalese or engineering speak I sometimes encounter. There is a subtle difference. Posture is ad ducted trochanters or radial nerve impingement. It is compression of the radial nerve, or non neutral posture and position. Using the risk factors as a basis for descriptions is the ergonomically correct language.
