Analysis of Research Trends Using G-power in Physiotherapy Research in Korea: Systematic Review

ABSTRACT

Purpose@#This study examined the research trends using G-power centered on major Korean registered sites and presents the research trends of studies with a high level of evidence.Method: This study selected three research journals listed in the Korea Research Foundation among physical therapy journals in the field of physiotherapy. The selected papers were classified according to the following: 1) study type, 2) study level, and 3) quality of the study.Result: Sixty-nine articles were selected and classified according to the study type. The musculoskeletal system, central nervous system, and others comprised 73.91% (n=51), 17.39% (n=12), and 8.7% (n=6), respectively. The results were classified into 62 experimental studies, four observational analytic studies, and three descriptive studies. The experimental studies included 22 randomized controlled trials (level 2) and 40 non-randomized trials (level 3). Sixteen randomized controlled trials were classified for a qualitative evaluation, and 12 papers with a score of six or more (good) were found. @*Conclusion@#Many high-level studies were found in G-power, and the quality of the study was also good. Therefore, the effective number of samples obtained using G-power is one of the ways to enable high-quality research.
