Objectives: This study aimed to evaluate Ryodoraku diagnosis and evaluation of low back pain reported in Korean, Japanese, Chinese and English. Methods: Using web search on five Korean databases, two Japanese, one Chinese and one English, we selected studies on Ryodoraku diagnosis and evaluation of low back pain. Results: Our initial search returned 26 Korean studies, 17 Japanese, 2 Chinese and 1 English. From them, we found 14 studies suitable for the purpose of this study. In general low back pain, studies showed that F4 (bladder) was the most frequently suggested abnormal Ryodoraku. In specific low back pain, Ryodoraku had no recognizable relation to disease-specific low back pain, but abnormal Ryodoraku of F2 (liver) and F5 (gall bladder) was frequently observed. More foot Ryodoraku showed abnormal than hand Ryodoraku. Conclusions: The diagnostic values of Ryodoraku for F2 (liver), F4 (bladder), H5 (triple energizer), F3 (kidney), and F5 (gall bladder) can be good diagnostic references, and future studies should be conducted on the aspect of differentiation of symptoms and signs.
