When bones are not in proper alignment, it can impair proper blood flow, nerve conduction, and Qi (Acupuncture meridian energy) movement.  This can affect the bones and muscles in the area, but also the organs and glands that receive their nerve and Qi supply from the blocked region.  For example if the Qi, blood, and nerve supply to the liver are impaired, the liver function, including detoxifying the body, would be impaired, leading to accumulation of toxins in the body.

Misalignment of the spine and joints does not always cause pain, but it is still important to restore proper alignment. Bones can be realigned using slow mobilizations or quick manipulations.  A manipulation is much like what chiropractors call an adjustment.
