This study is to develop a new medical information management for strengthening pelvic muscle strength for vaginal prolapse. The study was 60 patients who admitted to internal medicine department of a general hospital in the Metropolitan area from April 11 through June 28, 2022. The basic information of the study participants used X2 -test. The comparison before and after the medical information application of patients with vaginal prolapse was performed by the t-test. Changes in health behavior for the treatment of vaginal prolapse were measured as 5, 10, 15, and 20 days. The results of this study are as follows. Firstly, in the case of frequent constipation, 65.6% of the experimental group was significantly higher than 46.8% of the control group (X2=5.83, p=.04). Secondly, the keckel movement averaged 8.72 points before applying medical information, significantly lower than the average 45.28 points after application (t=-3.72, p<.01). Thirdly, muscle strength strengthening decreased short time after 10 days of application than before medical information was applied, and then continued to increase. The results derived from this study proved to be effective in treating vaginal prolapse. The results of this study can be applied to other vaginitis and urinary incontinence
