To my friends with babies or who are about to have them: If for whatever reason you come across a chiropractor who wants to perform spinal manipulations on your child, kindly pick up your baby, walk out the door and never return. I really can't see any justification for what the chiropractor does to this infant at 0:22.
Colic, acid reflux, constipation, and ear infections are NOT indications for thrusting baby spines. A chiropractor (or PT, or any provider for that matter) who informs you so is either unaware of the evidence or is trying to sell you. You may as well use Reiki, energy crystals or other forms of bogus voodoo treatment that have no real clinical effect.
