Many injuries that physiotherapists treat are not from trauma but rather poor body mechanics associated with prolonged sitting (ie. neck and back pain). Here are some tips that can improve workplace ergonomics, decreasing stress on these structures while sitting. Feet should be flat, knees 90 degrees, thighs supported and hips all the way back in the chair. Backrests should support the natural curve of your spine. Chin tucked slightly and head centered. Some tools to help include telephone headsets, adjustable computer monitors and footrests. Sit-stand work stations can be beneficial and support the recommended 20 min sitting, 8 min standing and 2 min of movement for every 30 min of work.
