I proceed to palpate on both sides of the spine, using one finger and thereby determine which one or both of the 12th pair of nerves and the one or both of the kidneys are affected. This is determined by the rigidity of the nerves; those affected will be swollen and sensitive to pressure. Palpation is made by a verticle movement back and forth of a half-inch. The sensitive, contracted nerve or nerves may be followed to the affected kidney or kidneys.
D.D. Palmer claimed he could palpate the 12th thoracic nerves all the way to the kidneys.
