Back pain may be the result of poor ergonomics and posture if the back pain is worse at certain times of day or week (such as after a long day of sitting in an office chair in front of a computer, but not during the weekends); pain that starts in the neck and moves downwards into the upper back, lower back, and extremities; pain that goes away after switching positions; sudden back pain that is experienced with a new job, a new office chair, or a new car; and/or back pain that comes and goes for months.

Keep the body in alignment while sitting in an office chair and while standing

When standing, distribute body weight evenly to the front, back, and sides of the feet. While sitting in an office chair, take advantage of the chair’s features. Sit up straight and align the ears, shoulders, and hips in one vertical line. Any prolonged sitting position, even a good one, can be tiring. Shifting forward to the edge of the seat with a straight back can alternate with sitting back against the support of the office chair to ease the work of back muscles.

Some people benefit from a naturally balanced posture that is achieved by sitting on a balance ball; in this posture the pelvis is rocked gently forward increasing the lumbar curve which naturally shifts the shoulders back (similar to sitting on the edge of a chair seat).

Also be aware of and avoid unbalanced postures such as crossing legs unevenly while sitting, leaning to one side, hunching the shoulders forward, or tilting the head.

Get up and move

As muscles tire, slouching, slumping, and other poor postures become more likely; this in turn puts extra pressure on the neck and back. In order to maintain a relaxed yet supported posture, change positions frequently. One way is to take a break from sitting in an office chair every half hour for two minutes in order to stretch, stand, or walk.

Use posture-friendly props and ergonomic office chairs when sitting

Supportive ergonomic “props” can help to take the strain and load off of the spine.Ergonomic office chairs or chairs with an adjustable back support can be used at work.

• Footrests, portable lumbar back supports, or even a towel or small pillow can be used while sitting in an office chair, on soft furniture and while driving.
• Using purses, bags, and backpacks that are designed to minimize back strain can also influence good posture.
• Proper corrective eyewear, positioning computer screens to your natural, resting eye position can also help to avoid leaning or straining the neck with the head tilted forward.
