Objectives : The purpose of this study was to examine the effect of thread-embedding therapy against partial obesity. Methods : 9 women from 20 to 30 with partial obesity were treated with thread-embedding therapy and then surveyed satisfaction, reaction after treatment and whether they were re-treated or not. The results of before and after treatment were compared with physical measurement, body composition tests and fat thickness measured by ultrasound. Results : The satisfaction of patients was high and side effects were pain, bruises and unnaturalness of action, but 8 of 9 patients wanted to re-treatment. The effect of thread-embedding therapy against partial obesity was continuous and was most pronounced during the first week. Conclusions : Thread-embedding therapy may be useful to reduce partial obesity without different treatments of obesity, diet, exercise etc.
