Keys to RSI Prevention
- Relax your upper back and neck and let go of your shoulders because tension in these muscles blocks blood flow to the lower arms and hands which can result in inflammation and development of Repetitive Strain Injuries.
- Keep your should blades free. Set backrest below the should blades and angle it forward so you can use the top of the backrest as a “self” upon which you rest your upper back.
- Eliminate Extension. When keyboarding, keep your elbows back and arms close to your torso. When not keyboarding, completely rest your arms on the armrests.
- Keep your wrists straight. Type as close to your lap as possible and float your hands over your keyboard, keeping your arms straight.
- Maintain Pelvic Stability. This is critical for reaction of injury-causing static muscle tension in the upper back, neck and shoulders. (See adjustment options below)
- Set seat height so your hip joint is slightly higher than your knee joint. Seat pressure should mainly be under your sitting bones and not under your thighs.
- Sit all the way back on the seat so your back is supported by the back rest. Then let the backrest do the work, let go of your back muscles, and let the backrest do the work.
