Poor Desk Posture

Why Prolonged Sitting Sucks – How to Save Your Spine

Poor Desk PostureA common misconception is that you won’t be injured from sitting. The fact of the matter is that you don’t need a forceful physical trauma to sustain an injury. Injuries can indeed occur form mere sitting! These are commonly understood as postural strain type disorders in which there is repetitive and cumulative microtrauma to the tissues of the body. The sad truth is that the majority of people sit for most of the day. An average day consists of sitting at a desk for hours staring at a computer screen, sitting when driving to and from work, sitting during meals and more sitting in front of the TV. That’s quite a lot of sitting! Some of the worst culprits are students, office workers and people who drive for a living.

So what is wrong with prolonged sitting? With prolonged sitting, there is a tendency to slouch forward (or you may have poor posture to begin with). Ultimately with sustained postures, you end up consistently loading the same tissues in the same way (ie: your muscles, ligaments and joints). Over time, this leads to a phenomenon known as creep. This is similar to the mechanism by which dentists use braces to repair crooked teeth. The braces impart a constant force to the teeth such that over time, the tissues surrounding the teeth deform to allow the teeth to move into better alignment. Similarly, in your back and neck, prolonged postures can result in structural changes (affecting joint position and alignment), postural strain to the muscles and sprain to the ligaments. Common complaints include neck and shoulder pain, upper back pain, low back pain and headaches. These problems can become chronic if nothing is done. Soft tissue creep from prolonged slouching also impairs the reflex contraction of back muscles which normally act to protect the underlying spine from injury1. Thus, a person is more likely to sustain an injury immediately following prolonged sitting.

Solutions:

1) Move around!

Don’t sit for more than 40 minutes straight. Get up, go for a walk, move around or stretch. Range of motion exercises and spinal extension exercises are good. Make sure to change your position frequently (ie: take micro-breaks!) as this will help redistribute the forces acting on your body. Did you know that fidgeting is actually good for you? Besides burning extra calories, it helps to redistribute the forces acting on your body. Another good tip is to drink plenty of water. Besides hydrating the body and flushing out toxins, drinking plenty of water forces you to get up frequently to go to the bathroom!

2) Don’t slouch!

The unfortunate tendency for desk workers is to slouch. The head juts forward, the shoulders and upper back curl forward and the normal backward curve of the low back is reduced. Over time, this leads to a postural problem known as “upper crossed syndrome.” Upper crossed syndrome describes a pattern of muscles which are either chronically tight/shortened or weak/lengthened that develops over time2. Instead, sit erect maintaining the natural curves of your back. You may consider purchasing a lumbar support.

3) Stretch those muscles!

The muscles that are most important to stretch are those which are being chronically activated or shortened. These most typically include the pectoralis muscles, SCM, upper trapezium and levator scapula.

4) Focus on ergonomics!

Having an ergonomic office setup is important. For example, your computer screen is ideally placed straight in front and should be at a level that is directly in line with your eyes when you look forward. Make sure you have a comfortable chair that is adjustable. Make sure your keyboard and other equipment are placed close enough to avoid excessive/prolonged reaching and slouching.

5) Workout!

It is good to have an exercise routing during the workday. Exercise is good for the cardiovascular system and overall health. Doing core strengthening exercises is also good because the muscles of the core help protect the spine from injury.

6) Visit your chiropractor!

Your chiropractor will assist you in determining the best course of action for your problem and the best exercises for your case. Chiropractors use spinal adjustments to help restore proper alignment and mobility and keep you functioning optimally.

Remember: Have some faith and patience! Postural problems don’t develop over night and rarely go away over night. You need to change your bad habits into good habits and over time, your back (and overall health) will thank you.
