If you are going to be proactive about getting and staying comfortable, you most likely need an expert to help you. A workplace study, published in the October 2009 Journal of Occupational and Environmental Medicine, and involving about 1500 people, found that just buying an ergonomic desk set up isn’t enough to address the posture related pain due to work positions.

Non-Neutral Work Positions can Cause Muscle Tension and Pain.
Work related pain often comes from holding yourself in what ergonomists call non-neutral positions. These positions are ones in which the joints are not centered, i.e., the two bones that make up a joint are not aligned with one another. The fit just isn’t right. This reduces how much support you can get for the position you are in. Non-neutral positions create a tremendous amount of tension (and pain!) in the body, because the muscles become like bones in order to scaffold the joint’s position.
After 18 months, improvement was seen in those who not only received new desks and chairs, but also received the benefit of professional help in setting them up. These workers had less muscuolskeletal pain and less eyestrain than the comparison group. Results from this study apply only to workers who began the study with pain. Those who started pain free didn’t seem to benefit from the ergonomic perks provided by the study.
“Just providing new office furniture and written instructions is not sufficient to achieve proper accommodation,” the authors conclude. “Good office equipment is a poor substitute for good working positions.”
