Today, we're going to talk about how bending forward at the back can put more pressure onto your disc, and how does that work. So, in a bit, I'm going to have a zoom in onto the vertebrae walls. But, for now, picture the disc, basically it’s a little cushion between the two vertebrae, like a water bag. So, imagine we squeeze the water bag one way, say, in this case, the front, the liquid will go backward. And vice versa, if we go push back this way, the liquid will go back. So, picture the disc, so when you bend forward, especially the younger you are, the healthier your back is, your disk is actually quite hydrated, meaning they're pretty liquid. So, by putting or by bending forward, you're putting quite a bit of hydrostatic pressure backward. And if you do it enough times, that can weaken the shell of the disc and get this material to leak out. But the same tokens that, if we go backward, we can put that pressure back onto basically this water bag. We can use the same methods, or same mechanism to get this material back. So, this is basically one of the explanations of McKenzie of the backbone on how this works. So, in the following video, you're going to have a little breakdown on how the disc works. This is the low back vertebrae. So, to orient ourselves; top, bottom, back, and the front. So, this is the disc. This is what we call a spinal nerve. This is the spinal cord. So, I want you to be able to see when someone's have a disc tear over here, the little red part right here. So, when you flex forward, you will see the jelly sort of come out right there and pushing onto the nerve. So, we can pay attention to about right over here. Going to put this on the side. So, when you have compressions and bend forward, you see the jelly comes out. And that jelly right there is actually going to push onto the nerve, and that's what can cause symptoms like Sciatica, or leg pain. So, that's that. In the clinic, we believe education is power. We empower our patients by really educating them and share the knowledge about their conditions with them so they feel less fearful about the conditions. And hopefully, in this case, you learned more about why bending forward actually may hurt your back, and what you can do about it. So, if you liked this video, please give it a like, and comment below if you have further questions about what you can do and what we can do to help with your low back pain.
