A relationship has been found between the cranial bones and the feet and
toes. It was observed that patients complaining of unresolved pain in the
feet and toes would respond to treatment based on standard Sacro Occipital
Technique cranial indicators in the low back, as proposed by Major Bertrand
DeJarnette. A theoretical relationship between cranial bone position and
proprioceptive activity in the joint receptors of the feet and toes is
explored. Also, methods of diagnosis and treatment are presented using pain
reflex points on the feet and toes to determine cranial bone position or
fixation.
