Is it really repositioning a misaligned vertebrae?
Or are we actually using adjustments as a tool to improve feedback from the spine to the brain? Spinal manipulation results in measurably smoother movement – and quite significantly so. (The Spine Journal, 14(11), 2618-2627). This is important, as smooth motion is a pre-requisite for fine control. So it may be that spinal manipulation has an important role in restoring joint sensitivity and movement control.
