Acupuncture is a safe and effective adjuvant therapy that effectively improves exercise capacity in patients with stable COPD, according to researchers from Spain.  They studied 102 patients with stable COPD who were randomly divided into two groups.  The acupuncture group received needling at points to strengthen the Lung and Spleen (Zusanli ST-36, Pishu BL-20, Feishu BL-13 and Dingchuan M-BW-1) three times a week for six weeks, in addition to routine medical treatment; the control group received routine treatment alone.  After six weeks of treatment, perceived exertion scores in the acupuncture group were significantly better than those in the control group.  Post-treatment improvements in six-minute walk distance, lung function and oxygen saturation were also significantly greater in the acupuncture group than in the control group, showing that the acupuncture group had better exercise tolerance.  (Acupuncture treatment of lung-spleen Qi deficiency in stable chronic obstructive pulmonary disease: a randomized, open-label, controlled trial.
