Auricular Acupuncture vs. Progressive Muscle Relaxation in Patients With Anxiety Disorders or Major Depressive Disorder.

Auricular acupuncture according to the the NADA protocol includes the needling of five specific acupuncture points on both ears: point 51 (= Sympathetic point), point 55 (= Shen Men), point 95 (= Kidney point), point 97 (= Liver point) and point 101 (= Lung point). All points were acupunctured with fine sterile single use steel needles with the size of 0.25 x 20 millimetres. The needles were inserted about 2-3 millimetres, so that the needle point pierces the skin and is just positioned in the cartilage of the ear. They remained in position for 30 minutes.

Progressive muscle relaxation was carried out by the method of Bernstein and Borkovec. All participants were asked to close eyes while sitting comfortably. Each group session included 16 main exercises of consciously tensing and relaxing specific groups of muscles.
