A Review of Clinical Studies for Chinese Medicine Treatment of Post-concussion Syndrome Using the CNKI Database

Abstract

Objectives: The aim of this study was to investigate the latest clinical studies on Korean medicine treatment of post-concussion syndrome (PCS) in the Chinese National Knowledge Infrastructure Database (CNKI).Methods: We searched the last 10 years of clinical studies discussing Oriental medicine-based treatments for PCS in the CNKI database. The search focused on the authors, publication year, type of study, purpose of the study, method and duration of treatment, evaluation criteria, and results of each article.Results: Of the 22 selected studies, 1 was a non-randomized controlled trial (nRCT), 2 were case series, and 19 were randomized controlled trials (RCTs). Treatments included oral herbal medicine in 16 studies, oriental medicine through external use in 2 studies, acupuncture in 3 studies, and traditional Chinese medicine injection in 2 studies. The most frequently used herb was Cnidii Rhizoma (川芎). All 22 studies confirmed the efficacy of Oriental medicine treatments.Conclusion: More varied and scientifically designed clinical studies are required to develop treatments for PCS. The results of this study could be used as basic data for further PCS studies.
