A study found that spinal adjustments shift how your body processes proprioceptive input from lumbar muscles. Patients whose nervous systems relied more on proprioception before treatment showed greater pain relief after adjustment, suggesting your baseline nervous system strategy predicts whether you'll respond to the treatment.
So the researchers compared lumbar spinal adjustments with lumbar mobilization and no intervention. They ultimately wanted to determine whether a single lumbar adjustment could change proprioceptive processing and whether a patient's baseline proprioceptive strategy or baseline ultimately could influence how much pain relief they experienced. So the results are pretty cool. After the lumbar adjustment, the participants in the study did demonstrate a strong shift towards using proprioceptive information from the lumbar muscles. And I say even more interestingly, the researchers found that patients' proprioceptive profile before the care was delivered was associated with their pain response afterward. So it did not simply tell us that an adjustment can reduce pain. It begins to explain something really cool, which is how the nervous system could respond to the adjustment and why different patients might respond differently.
