I received this question on my Facebook fan page.
I have a question about hyper mobility, and or releasing pent up gasses between vertebrae. In other words, I creek and crack a lot after 40 years of skiing, and swimming, and biking, and throwing myself off cliffs and cracking ribs, you know, that sort of thing. Should I ask it on your blog? When I do “crack” my neck, or lower back by stretching, it feels fantastic! I am in no pain, unless I sleep wrong, and this releases it. What is this?

FIrst, I should begin by saying, that if the ‘crack’ does not induce pain, it is probably not doing you any harm. My grandmother used to tell me that cracking my knuckles would cause arthritis, and in spite of this, I did it anyway (sorry Grandma.) When I was in medical school, I started to wonder if this was true, and after exhaustive research employing a whole host of medical student lackies, I can state that there is no evidence that cracking your knuckles (or your back) will cause you arthritis.
Now, there have been informal studies that have shown that when you crack your own back, that you are usually unable to ‘self-correct’ the segment of your spine which actually needs to be moved- you are cracking the ones above or below it. It may provide you some relief, but ultimately it may not fix your underlying problem and you may find yourself in the same discomfort an hour, a day, or a week later. Having the correct segments adjusted by your Osteopath or Chirppractor may give you longer lasting and ultimately more satisfying results.
As for the release of pent up gasses- yes, there is a school of thought that believes that the sound you hear when you have your spine corrected is actually the shifting of nitrogen bubbles within the joint. After further research (and more lackies) I have found that there is no conclusive evidence about what that crack may actually be. As an aside, in my own practice, i do relatively little ‘cracking’ of the spine as my approach is based more on gentle mobilization. You would not believe how often I hear sounds of disappointment when patients realize they are not going to hear that loud ‘CRACK’ when I adjust them- they have come to associate that sound with relief.
I hope this answers your question. Thanks for visiting the blog.
