A. People often ask why we see so many cumulative trauma disorders today, when we heard very little about this problem a few years ago. There are many reasons for this. Jobs are different. Work technique is different. People are different.
Attitudes are different.
The world is changing. Years ago, a typical worker carried out several tasks using many muscles in a variety of postures with heavy physical effort. Today's jobs, however, often require the worker to hold a sustained posture such as sitting or standing all day while they carry out the same task over and over and over. Years ago workers used most of their muscles to do work all day long. Many jobs today focus the entire work day onto one or two small sets of muscles that must hold or repeat a motion all day.
