About this number

A rhythm of 6 to 12 cycles a minute that craniosacral therapists say they can feel in the skull and spine. When examiners were tested without knowing each other’s readings, they did not agree on its rate. A 2016 systematic review found no reliable evidence that it exists as a distinct rhythm.
