No part of the body escapes the dominance of the nervous system. Improper function of the spine due to slight misalignments (subluxations) can cause poor health or function, even in areas far removed from the spine and the spinal cord, itself.
Misalignments can also reduce the ability of the body to adapt to its ever-changing environment. Even the slightest malfunction of the spine may alter the regular transmission of nerve impulses, preventing that portion of the body from responding optimally.
Similarly, misalignments can also occur in other joints of the body like the shoulder, knee, ankle, etc. Chiropractic adjustment on these joints would help reduce pain and improve mobility and function.
