The aim of our study was to demonstrate the ratio and the management of shoulder pain in high school athletes by questionnaires and interviews. In our study, we asked 2, 209 athletes (1, 299 male, 910 female) about their shoulder pain by questionnaires. And we asked the managers how many athletes who had complained of their shoulder pain and how to deal with their shoulder pain in interviews. 42.2% of male and 32.3% of female, 38.1% of the athletes in total had experienced shoulder pain in their sport lives. Among the athletes who had complained of shoulder pain in questionnaires, only a few really complained of their shoulder pain to their managers. Most of the managers ordered their players to refrain from training, but a few of them left it to the player's measure. Both the players and their managers tend to make light of shoulder pain, therefore, the degree of the shoulder disorders had become worse at the time of the treatment. So, we must make the appropriate prophy-lactics to prevent the incidence of sever shoulder disorders.
