Traditional Chinese Medicine, when used alongside dopamine replacement therapy, could potentially improve the severity of symptoms in Parkinson's disease patients.
The study conducted a meta-analysis using electronic searches in PubMed, Cochrane Controlled Trials Register, China National Knowledge Infrastructure, Chinese Scientific Journals Database and Wanfang data to find randomized trials evaluating the effectiveness of using TCM as an additional treatment to conventional treatment for patients with Parkinson's disease. The Unified Parkinson's Disease Rating Scale score was used as a measure to determine the effectiveness of the therapies.
The evaluation of the studies, which included 27 articles involving a total of 2314 patients from 1999-2013, showed marked improvements in the symptom score for patients undergoing combination treatment of TCM plus dopamine replacement therapy, particularly when compared to dopamine replacement therapy alone. More specifically, acupuncture as an add-on to traditional treatment showed substantial benefits for improving the symptom score of patients with Parkinson's disease. However, TCM as a standalone treatment did not improve the scores. The results also suggested that the effectiveness of using TCM as an adjunct therapy tends to be more noticeable in Parkinson's patients with longer durations of the added therapy. Overall, the use of TCM as an additional treatment was safe and well-tolerated by patients.
