Researchers at Kyoto University conducted a randomized study of 68 patients who were taking standard medications for COPD in various stages. They were randomly assigned to have actual acupuncture or a placebo treatment in which needles did not penetrate the skin. Patients received treatment once a week for 12 weeks.
Results showed a statistically significant improvement in dyspnea ratings. As their dyspnea subsided, patients also demonstrated in tests that they were able to tolerate exercise better and increase the distances they were able to walk.
The study was led by Masao Suzuki, PhD, and published in the Archives of Internal Medicine.
