Need for Registration and Reporting of Acupuncture Trials in Parkinson's Disease in Korea.

OBJECTIVE: Many people dealing with Parkinson's disease (PD) turn to complementary and alternative medicine when searching for a cure or relief from symptoms. Acupuncture is widely used in the Korean PD population to alleviate symptoms and in hopes of curing the illness. However, acupuncture use for PD patients has only recently begun to be studied scientifically and is still considered an unproven treatment for PD. Therefore, there is an urgent need for acupuncture to be studied, validated and used for PD. Thus, our study's aim is to examine how many acupuncture studies in PD are registered and reported in Korea.

METHODS: The registries Clinicaltrials.gov and the Clinical Research Information Service (CRIS) and the search engine PubMed were searched to find relevant human clinical studies involving acupuncture therapy in PD patients. We examined the registration of trials, the posting and publication of results, and whether published articles were registered.

RESULTS: In Clinicaltrials.gov, one completed trial was found with published results. In CRIS, one completed trial was found with published results. A total of 6 publications were found in our study: 2 articles were registered, but only 1 had the registered trial number listed in the article.

CONCLUSION: Acupuncture is popular among the PD population in Korea regardless of its unproven safety and efficacy. Despite the pressing need for clinical trials, the number of studies listed in the registries was small, and only a few publications were registered. More effort and rigor are needed to validate the efficacy and safety of acupuncture for PD.
