12 Ergonomic Adjustments That Reduce Injury Risk at Work
4. Foot Support and Leg Positioning - Circulation and Comfort

Proper foot support and leg positioning play crucial roles in maintaining circulation, reducing lower extremity discomfort, and supporting overall postural alignment throughout the workday. Research conducted by the European Agency for Safety and Health at Work reveals that inadequate foot support contributes to leg swelling, varicose veins, and lower back pain in up to 30% of seated workers. When feet cannot rest flat on the floor due to desk height or individual stature, a footrest becomes essential for maintaining proper ergonomic positioning. The footrest should be adjustable in both height and angle, allowing users to position their feet flat with ankles at approximately 90 degrees and thighs parallel to the floor. Studies published in the International Journal of Industrial Ergonomics demonstrate that proper foot support reduces pressure on the back of the thighs by 25%, improving circulation and reducing the risk of blood clots associated with prolonged sitting. The footrest should be wide enough to accommodate both feet comfortably and allow for position changes throughout the day. Additionally, there should be adequate legroom under the desk to prevent contact with the knees or thighs, which can restrict movement and circulation. Workers should be encouraged to flex their ankles and change leg positions regularly, as static positioning for extended periods can lead to muscle fatigue and circulatory problems that impact both comfort and health.
