2) Arms: your elbows should be placed at your sides bent at 90 degrees, typically resting on an arm rest of appropriate height. Your forearms should rest on the work surface with the keyboard so your wrists are not either too flexed or extended. As most standard desks are too high to allow for this, mobile work surface that you can raise and lower should be installed or you can raise your seating surface. Gel wrist supports for the keyboard and/or mouse can be helpful if you're spending numerous hours at the computer but they should be used as a cue to hold your wrist in a neutral position, not relied upon as a true support. Continuous torque on the wrist is the fastest way to develop carpal tunnel symptoms.
3) Back: your low back should be in a neutral position - not arched nor rounded. Your shoulders should be stacked on top of your hips, not hunched over. If your shoulders are hunched, see the two items above. Be wary of lumbar supports, they often put the user in too much of an arched low back.
4) Hips/legs: your knees should be level with your hips and feet flat on the floor. This can be accomplished by lowering your seating surface or purchasing a foot rest (or even a phone book!) of appropriate size.
There are numerous items on the market to help make your workplace more ergonomically friendly. Take a look at an office supply store or online if needed.
Most importantly, TAKE BREAKS! As stated earlier, the human body is not meant to stay in any position for a prolonged period. If needed, set a time every 30-60 minutes and change positions. Each break can be as long or as short as you need it to be, simply getting up for a glass of water makes a huge difference.
If you're having trouble assessing your workplace or continuing to have pain while at this position, come see a physical therapist at CORE Services, Inc. We can simply make a few recommendations as to how you can create a better environment, or assess and treat your pain if needed.
