Many clients who come to me with back pain ask about lumbar supports; do they have the right one? Should they use it or not? Science Daily cites studies reporting that lumbar supports don't actually help those with back pain. I agree. And here's why...
Back pain is a result of chronically contracted back muscles.
Your back doesn't need "support" to "fix" your pain; it needs those chronically contracted muscles to be addressed! Every time we are called to action (the phone rings, our children call us for help, running to catch the train, checking our email, standing at our job) our back muscles contract to enable us to move forward and "get the job done." This is called the Landau Response. Thomas Hanna called it the Green Light Reflex.
The Landau Response is a primitive brain stem reflex hardwired into our nervous system that instantly contracts our back muscles in walking, running, reaching, bending, etc. However, when that reflex is triggered hundreds of times a day it can become habituated and cause the back to arch like a bow while the shoulders tighten back and the neck straightens. It can contribute to sciatica, hip, shoulder, neck and joint pain. It's a useful reflex, but we don't want to get stuck in it. When muscles tighten even when we are at rest, this is called Sensory Motor Amnesia (SMA). The photo at left shows what an habituated Green Light Reflex looks like.
When we use a lumbar support, our lower back is actually being encouraged to STAY arched, as in the photo on the right. Perhaps this is why the studies cited in the Science Daily article found that lumbar supports didn't actually relieve people's back pain.
Back pain comes from contracted muscles, therefore it is important to learn to RELAX those muscles through gentle Somatic Movements. Then you can learn to sit balanced and straight, rather than with a supported curve. Try this easy seated movement in order to improve your sitting. You can save yourself some money (and pain) by not having to buy that lumbar support.
