Dr. Stephen Levine:
So, part of my background as a certified chiropractic sports physician, I spent years working with athletes. I worked up at Seton Hall University back in the ’90’s. We saw a lot of track and field people. Not just track and field, but most athletes would come in with a complaint saying that, “Doc, I’m getting these hamstring pulls, or a groin pull. But it’s always on the same side. Why is that?” You can treat it at the training room, but if we’re not getting to the cause of the problem, which might be maybe one hip’s higher than the other, and if the hip’s higher than the other, maybe it’s compressing the nerve from the spine.
So, the nerve, which exits out of the lower back, will affect the function of the muscles. So, when we take an x-ray, we take an x-ray standing up, not lying down, because I want to see posturally what’s going on, and if one hip comes up higher, it’s compressing the nerves on one side. And these are the nerves that go into the quads, the hamstrings, the calves and that’s why regardless of your sport. We’re all that weekend athlete or competing, or just training on our own. Why is one side getting tighter? It might be this, or it might be the pelvis is rotated, and we can see that on film. We can measure the nerve function, and as a result we can come up with a solution.
