As a medical art, it has evolved with the passage of time. Acupuncture has been used for 1,500 years in Japan and 200 years in Europe but has only been used to any significant extent in the U.S. for 25 years. Comparatively recent developments include the use of electrical stimulation and treatments solely based on neuroanatomic principles. The clinical literature of controlled trials includes treatment of low back pain, headaches, arthritic pain, extremity pain, postoperative pain, respiratory problems, urologic problems, and substance abuse. Uncontrolled reports include claims of effective application in almost every discipline of medicine.
Acupuncture needles are much thinner than needles used to draw blood or give injections.
They are available in sizes ranging from 30-36 gauge. The depth of insertion depends on the type of treatment and location of the point as well as the size of the patient. Points on the buttocks may require insertion of 3 inches or more. The usual range is 5-10 needles in any given treatment. There may a pinching sensation when the needle first passes through the skin.
