6 rules to prevent back injuries from sitting

6789409-fantastic-back-wallpaper

Some scientists believe that we are predisposed to have back problems due to the fact that humans spine is held in a vertical position, unlike animals that walk on four feet. Because of that, the vertebrae, especially the lumbar spine,  is constantly bearing the compressible weight of the body above it and also the force of gravity, leading eventually to a back problem.

It’s not surprising that back pain (lumbago) is one of the most important health problems in the world. According to the CSST of Quebec, more then 37 000 people were off work due to back pain in 1995 and 55% of those cases involved the lumbar region.

Nowadays, people spend much of their time sitting in front of a screen, whether it’s in front of a computer, a smartphone, a tablet or a television. According to a recent US study, an adult dedicates an average of 8 hours per day in front of these electronic devices. (Rideout, Foehr et Roberts, 2010)

A poor sitting posture commonly produces low back pain. When we sit in a certain position for a few minutes, the muscles that support our low back become tired and relax. Our body sags and this results in the slouched and rounded sitting posture. If we maintain this bad posture for long enough, it causes overstretching of ligaments, pain and distortion of the discs.

To prevent back pain from sitting for prolonged periods, here are some simple things you can do by yourself :

  • Adjust the height and tilt seat so your elbows, knees and ankles are resting at 90 degree angle;
  • An elbow support is highly recommended because they allow to reduce the lumbar region of the weight represented by the upper body;
  • Be sure your feet are supported by the floor, if not, add a foot rest;
  • Slightly adjust the inclination of the seat-back between 5-15 declined angle, your back should be supported by the seat-back. If not place a cushion between the curve in your lower back and the back of the chair;
  • The distance between your eyes and your computer screen should be about an arm’s length or 30 cm;
  • Last thing, avoid sitting for a long periods of time (take 1-2 minutes to stretch every 30 minutes)

  1. I see McKenzie in your bibliography. Great book. Since starting a regular exercise regime and in particular paying attention to strengthening my core, hips, and upper back I haven’t had an incident in nearly 2 years. (God, I hope I’m not jinxing it by saying it out loud!)

  2. I have a computer job and sometimes have to sit at a desk for long periods of time. I like that you mentioned using a cushion for your back, that is a smart way to avoid back problems. I will make sure to try this when I go to work.
