Rempel: We know from some of our early work that when the wrist is in a more straight posture and not bent backwards in extension and when the forearm is rotated slightly so the palm's not pointed straight down at the desk - that's called a fully pronated position - that that will decrease some of the load on the muscles in the forearm and on the nerves.
Narrator: Rempel says his lab is looking for more intervention research.
Rempel: Randomized, control trials that demonstrate what kind of interventions are effective and which ones aren't in reducing musculoskeletal problems. I think we'll see more of that kind of research emerging over the next ten years. Not only for office work, but for construction and other kinds of work practices.
