Brazilian investigators have found that auricular acupuncture can reduce disability in people with chronic spinal pain. In a clinical trial, 110 people were randomised into three groups; treatment, placebo and control (no-treatment). Auricular acupoints used in the treatment group were Shenmen, Kidney and Sympathetic, along with Cervical Vertebrae, Thoracic Vertebrae and/or Lumbar Vertebrae, depending on the location of the pain. In the placebo group, the single point Eye was used. Both groups received five sessions of auricular acupuncture, once a week, over a period of one-and-a-half months. A significant reduction in disability was observed in the treatment and placebo groups between the initial and final assessments (one week post-treatment), and between the initial assessments and follow-up (15 days post-treatment). In the final assessment, the treatment group showed improvement of disability compared with the placebo and control groups.
