Spinal bracing- these two words should not be used together in the same sentence unless you have sustained a major accident, injury, or trauma to the spinal region that was life threatening. In that case then yes. For the other 99% of the population bracing should only be acceptable when dealing with the teeth. The spine is supposed to be freely movable due to the fact that it interprets all of your external and internal data via spinal nerves through movement.
When a subluxation (misalignment within the spinal column) exists within the spinal column it applies pressure on a spinal nerve thus creating a chronic state of fight or flight. Not only does the subluxation create dysfunction within your body it also creates inappropriate movement patterns. Your body enters into a state of survival and fortunately/unfortunately people can learn to live this way. The body can learn to live in a chronic state of dis-ease (which means your body is not at ease). This is, in part, due to your adrenal glands firing off more than they should be due to the inability to adapt to the stressor placed upon yourself in the spinal column.
Anyone who has had braces on their teeth knows how long it can take to move teeth. That perfect smile doesn’t just happen overnight, an orthodontist slowly applies pressure to move the teeth over many months. Chiropractic care uses the same approach with correcting spinal subluxations. It takes time for a spine to become subluxated, and it also takes time to retrain the body to get back to proper alignment. The best way to take care of the future is to take care of the present moment. The most important project you’ll ever work on is yourself.
