The purpose of this study is to investigate reasearch trend of acupuncture treatment on shoulder impingement syndrome. This study investigated the recent studies about acupuncture treatment for shoulder impingement syndrome via searching Korean and foreign electronic databases(Research Information Services, National Digital Science Library, Oriental Medicine Advanced Searching Integated Services, PubMed, China National Knowledge Infrastructure). The search term was searched by combining 'shoulder impingement sydrome', 'subacrominal pain', 'acupuncture', 'needle therapy', and was limited to the articles published from 2005 to 2017. 14 studies were found to be analyzed according to the type of study, the number of cases, the type of treatment, the instruments for assessment and published year. 14 studies were published since 2005, 6 case reports, 8 randomized controlled trials. In the treatment of shoulder impingement syndrome, treatments such as acupuncture, acupotomy, pharmacopuncture, laser acupuncture, combined treatment of exercise and rehabilitation were performed. Visual analogue scale(VAS), range of motion(ROM) and various questionnaires were used as primary assessments. In each study, acupuncture treatment was reported to have a significant effect in the pain, range of motion and disability of shoulder impingement syndrome. In order to ensure objective evidence on acupuncture treatment, large scale case reports and randomized controlled trials should be continued.
