We evaluated baseball players in little league at medical screening including examination of the shoulder joint and flexibility of the lower extremities.In this study, 58 baseball players in little league were evaluated from 2004 to 2006. The mean age of subjects was 11.3 years old ranging from 9 to 12. At medical screening, a specific medical examination of the shoulder joint proposed by Hara and test of flexibility were performed on each subject. A flexibility test for the hamstrings, quadriceps, iliopsoas, spine and hip joint was performed and scored (total 12 point). The players who had elbow or shoulder pain were classified as injury group and those without pain were classified as non-injury group.There were 8 players in the injury group. The average of shoulder scores (total 11 points) for the throwing side by a specific shoulder test were 6.3 points for the injury group and 8.4 points for the non-injury group and those for the non-throwing side were 7.9 points and 8.6 points respectively. The average of flexibility scores was 6.0 points for the injury group and 7.4 points for non-injury group respectively. There was no correlation between the total shoulder scores and the total flexibility scores. However, in the injury group, most of the shoulder and flexibility scores were less than 7 points and 8 points respectively. The specific test for shoulder joint and flexibility test were useful for detecting not only shoulder joint problems but also potential elbow joint injury.
