This is a specialized book focusing on the "pressure" (strength, depth, duration, etc.) of treatments, with detailed explanations and illustrations. - Title: Obsession with Pressure - Content: Explanations and illustrations regarding pressure in treatments Thank you for viewing. This book provides a detailed explanation of "pressure" during treatments. I believe it's safe to say that there isn't another book that systematically covers pressure, strength, duration of pressure, etc., to this extent. Anma, massage, and shiatsu therapists, judo therapists, acupuncturists, and therapists, please use this in your daily clinical practice. * There is some tearing on the cover, but the binding of the main body is solid. * Some pages have markings from a highlighter. Please be aware of this before purchasing.
