Why Your Low Back Pain Might Not Actually Be A “Back” Problem

Think you have a “bad back”? Maybe it’s time to check your knees and hips instead!

Pain is not always what it seems. The body is a complex system where each part influences the others. While we often think in terms of individual body parts, the truth is that we always move as a whole. When one area is not moving the way it should, another area often steps in to compensate.

This concept is known as regional interdependence. Physiopedia defines it as “the concept that seemingly unrelated impairments in a remote anatomical region may contribute to, or be associated with, the patient’s primary complaint.”

In simpler terms, this means that pain felt in one area may actually be coming from somewhere else.

For example, knee pain might not be a knee issue at all, but instead the result of an ankle that has been sprained multiple times. Similarly, low back pain may not be a back problem, but rather the result of hips that are not moving as they should.

As shown in the image above, certain joints in the body are designed primarily for mobility, while others are designed more for stability. Mobile joints like the hips and shoulders move through large ranges of motion in multiple directions. Joints designed for stability, such as the knees, move through more limited ranges. The knee, for example, primarily moves forward and backward with minimal rotation or side to side motion.

Problems arise when this balance is disrupted.

Let’s look at a common example. Imagine a soccer player who suffers an ACL tear. The knee is meant to be a stable joint, but now one of its key stabilizing structures is compromised. As a result, the knee becomes more mobile than it should be.

When this happens, the body looks for stability elsewhere. Often, this leads to reduced motion at the hip as it tries to compensate for the instability at the knee. This compensation can then continue up the chain.

If the hip loses mobility but the athlete still needs to sit, run, jump, and cut, all of which require significant hip motion, the next area to make up the difference is often the low back.

Over time, the low back begins to move more than it is designed to. The muscles in that area are forced to work harder and absorb stresses they are not well equipped to handle. Eventually, this can lead to persistent low back pain.

In this scenario, what presents as low back pain may actually stem from an old knee injury.

The body is remarkably good at adapting. It will find ways to work around injuries and limitations so you can continue functioning. Unfortunately, these compensations can eventually create pain in areas that were never the original problem.

This is why low back pain, shoulder pain, or other chronic issues are not always problems of the area where the pain is felt. To truly resolve pain, it is often necessary to zoom out and look at how the entire body is moving.

If treatment focuses only on the painful area, it is easy to get stuck in a cycle of treating symptoms without ever addressing the true source of the problem. If any of this sounds familiar, consider consulting a licensed professional who can evaluate your body as a whole and help identify what is really driving your pain.
