Move Differently. Hurt Less. Here's the Science. Brain and Spine.

Back pain has a way of showing up uninvited and overstaying its welcome — but if you're ready to do something about it, the science is getting excitingly specific about what works, and your nervous system is a greater part of that story than most people realize.

YOUR BRAIN IS PART OF THE PAIN PROBLEM (AND THE SOLUTION)

The research has something useful to say about this: back pain isn't always just a structural issue. A lot of what you feel is shaped by how your nervous system manages pain signals — and that managing can be trained as the 2026 pilot study published in Pain Management by Billens and colleagues explains. Two groups of everyday, non-exercising adults spent 10 weeks working through either a moderate running program or a more arduous strength-based routine. Then researchers gauged how participants' nervous systems were responding to pain. The findings? Individual responses suggested decreased pain inhibition following moderate-intensity training and better pain inhibition after high-intensity training — meaning the higher-intensity group showed signs that their nervous systems got better at dampening pain signals. Small study, yes, but a compelling early signal that how hard you exercise may influence how loudly your body broadcasts pain.

Maybe making more intense exercise would be a goal for you…or not! Old Mill Chiropractic is here to share interesting new info!

NOW, ABOUT YOUR SYMPATHETIC NERVOUS SYSTEM (YES, THIS GETS INTERESTING!)

Okay, bear with us here — because this part is actually kind of wild. Your sympathetic nervous system is your body's "fight or flight" button. Useful when a bear is chasing you. Less useful when it's chronically triggered by stress, poor sleep, and an inactive lifestyle. Turns out, animal studies suggest that higher sympathetic nervous system activity can accelerate bone loss — and the human story is probably not that different. (2) That's the basis behind CHILL BONES — yes, that's the actual name of a real clinical trial — described in BMJ Open in 2025 by Collier, Beck, Sabapathy, and Weeks. The trial combines high-intensity resistance and impact training with mind-body exercise (think: tai chi), testing whether calming the nervous system while loading the skeleton produces better bone and spinal outcomes than either method alone. Among the outcomes being tracked: lumbar spine bone mineral density. Mind-body exercise may be used to modulate sympathetic activity, which could have an additive benefit for skeletal adaptation when used in conjunction with high-intensity resistance and impact training. It's a trial still in progress, but the science behind it is hard not to find compelling. (2)

SO WHAT DOES THIS MEAN FOR YOUR BACK?

Taken together, both studies are saying the same story: your spine, your nervous system, and how you move are all tangled up in each other. Pain isn't just mechanical. Bone health isn't just about calcium. And "just rest it" is rarely the answer. Chiropractic care works with that whole system — improving spinal alignment, lowering nervous system irritation, and getting you going in ways that are actually therapeutic rather than just draining.
