Great Otto for pain and tension release. I use it by itself and also conjunction with Otto 128Hz.
The Otto 64 is used primarily on the lower back and hips for easing pain and stimulating the parasympathetic nervous system. This fork is great for body workers such as massage therapists, acupuncturists, chiropractors and people with back or hip pain.
Use this fork when you want to focus healing on the hips and the lower back/spine. Many have had good results in stimulating cranial sacral pulse when placing the stem of this fork around the foot and ankle.
