There is a measurable rhythmic pulsation (approximately 6-12 cycles/minute) within, and throughout, the central nervous system contained by the spine, sacrum, and skull, which is accompanied by other longer and slower wave patterns. When the mobility of the Cranial-Sacral system is restricted, altered, or disrupted because of injury, symptoms may appear. These can include jaw, tooth, facial, back, and neck pain; visual disturbances, hearing loss, tinnitus, sinus trouble, anosmia, insomnia, Bell’s palsy, trigeminal neuralgia, nystagmus, strabismus, and other cranial nerve dysfunctions, various emotional and thought disturbances, etc. Some of these dysfunctions may result from consequent neurological and/or vascular alterations.
