Adjustable sit stand workstations offer potential for reduction of high-risk postures. Personal management of posture reduces risks for discomfort and injury. As hours go by, workers become fatigued and tend to fall back into slouched postures, requiring less energy. An easily adjustable workstation and chair can provide opportunities to revert to low risk postures, avoiding discomfort and injury.
The most common discomforts associated with prolonged sitting are neck and back. An additional common risk associated with computer work is carpal tunnel. These 3 risk factors are obvious on the cover of the Orthopaedic Physical Therapy Journal, Vol. 31/number 2. The addition of an appropriate, fully adjustable ergonomic chair and an easily adjustable sit stand station may decrease risks significantly, IF the user is personally accountable for appropriate adjustments and computer entry movement techniques.
Changing positions frequently throughout the day will greatly reduce/ eliminate the risk for ergonomic discomforts if addressed as soon as recognized.
If sitting is the only option, it is recommended to stand, stretch and take a few steps, renewing low risk postures and readjusting chair if necessary.
When using a sit stand workstation, frequently (perhaps hourly) change from sitting to standing. Neutral, low risk posture, sitting or standing, should include:
Head over shoulders
Neutral inward low back curve
Arms relaxed at side of body
Elbows 90 degrees or slightly open
Hands and forearms elevated off work surface (both keyboard and mouse)
