Objectives This review aimed to investigate studies of Chuna manual therapy (CMT) for low back pain and the evidence of their effects in order to suggest a better research method in the future. Methods We investigated studies on CMT for low back pain by searching Korean web databases from 2020 to 2021. As a result, 72 research papers were analyzed according to their published year, the titles of journals, the types of studies, the techniques of Chuna, and the instruments used for assessment. Results The results were as follows: 1. There were three papers published initially in 2000. this number showed a steady increase, and a total of 72 papers were published that year. 2. Studies on CMT were mainly published in the Journal of Korea Chuna Manual Medicine for Spine and Nerves. 3. When categorized according to the methods of studies, a simple case report was used more often than the sum of randomized controlled trials (RCTs) and non-RCTs. 4. The most frequently adopted technique of Chuna in the examined studies was the COX flexion and distraction technique. 5. The Visual Analog Scale and Oswestry Disability Index were used as primary means of assessment. Conclusions Based on the analysis, it was observed that this review provided limited evidence of CMT use in patients with LBP. Therefore, further investigation using well-designed RCTs is required to obtain higher evidence.
