so most of the furniture today that we're using is built on a World War 2 model of a 5 foot 10 inch male so if you're that size of a person you're not going to have any problems in the workplace or with any other pieces of furniture but if you're not chances are you're gonna be struggling with your economics Randy's a bit taller than the ideal model so he's really having to slouch down in his seat and because he's having the slopes to get down to the workplace so much he's unable to put the proper amount of weight bearing on the lumbosacral spine which puts a lot of stress on those nerves and as he hunches his upper back and his head forward position is forward just an immense amount of stress and tension across the upper back those muscles are gonna fatigue over a long day and get injured so there's going to be strain and all these muscles in his low back and he's gonna create a lot of stress at this lumbosacral area which will eventually cause him some problems he's also not supporting his hands so by holding the weight of his arms up he's creating a lot of stress in these muscles which don't get any rest whatsoever so what we've had to do to correct Randy's position is to raise his computer screen about 4 to 6 inches that takes his eyeline from down here all the way up to ear keeps his head position better so he has about a 30 degree downward gaze to look at the content so in Randy's corrected posture we start with his feet firmly planted on the floor this puts his knees at a nice 90 degree angle and more importantly his lower leg and buttock are in a nice level position which meet the seat pan you don't want to create any pressure points which could create nerve interference and trapping muscle tension as well all the way back to the lumbar spine nice lordosis really what you want to do is stack all the weight of the upper body on a nice level lumbosacral area and that's what we're doing in this position his head posture sits again over the center of gravity so the muscles aren't working too hard in the neck by having a head forward position his head gazes properly at the content by being at the right position and having about a thirty degree downward gaze with his eyes and most importantly with the upper arms is to have the arms is hanging at the side and supported by the edge of the table or a lot of people will use a pad for their wrists but to not be firing any muscles up in here this is all quiet and he can just keep punch all day with little less as least amount of stress as possible so it's a bit about the importance of proper ergonomics in correcting chronic repetitive strain injury I'm dr.
