RESUMO
The purpose of this study was to examine the 13 musculoskeletal abnormalities [front head, lateral bending head, shoulder dropping, scoliosis, kyphosis, lumbar lordosis, flat back, pelvicobliguity, genu varum, x.leg, flat foot, pes cavus, and hallux valgus] after a period of exercise therapy on the blind boy students without secondary disability. In this semi-experimental research, 60 boy students were included from secondary and high school [12-18 years old] including 34 congenital blind and 26 semi blind. They were selected among 135 students at Tehran Mohebbi blind school. They were tested by measurement tools [symetrigraph, antropometer, and podioscope]. After examining the results by the New York test, the students who were diagnosed with one or more musculoskeletal abnormalities took part in four-month's exercises with 3 sessions at week. The results were registered after the end of the exercise program and administered secondary exam. The data before and after the exam were analyzed. 80 percent of the blind students at pre-exam had musculoskeletal abnormalities which are decreased to 45 percent after exercises. There were significant differences on the rate of recovery at 11 abnormalities [Exact - Sign = 0 < 0/05] and there were not significant differences at pelvicobliguity and x.leg abnormalities [Exact - Sign = 1 <0/05]. The research findings emphasized on the validation and important of exercise therapy on musculoskeletal abnormalities
