Introduction: The aim of this study was to determine the effect of the Corrective exercise on gait parameters and lung capacity educable retarded boys 14-18 years.
Methodology: To this end, 20 people, on a voluntary basis, targeted and were selected and then randomly divided into two experimental and control groups of 10 patients were examined. The subjects were asked to exercise for 24 hours before the tests, extreme physical exertion or avoid foods containing caffeine. The test subjects' consent form was completed by parents. The experimental group for 8 weeks, 3 sessions per week were divided about the intervention. Upon completion of the training period, all measurements were repeated varying the initial conditions. to determine changes within the group and between groups, and paired t test were used. The data collected were analyzed using statistical software SPSS21
Results: The results showed that the mean width change gait, stride length changes, changes in two steps, walking speed, mentally retarded boys corrective exercise and control groups there was no significant difference (p>0.05). The results showed that the mean deviation angle feet, FVC, FEV1 and the FVC/FEV1 mentally retarded boys corrective exercise and control groups there was no significant difference (p<0.05). But there was no positive results or improve the respiratory system and shown that this practice can have a positive effect on the respiratory system and spirometric indices.
Discussion: Corrective exercises in this study could be a solution cheap, convenient and uncomplicated for mentally retarded students improve gait parameters, especially in the field of copyright and walking speed is fast-paced.But there was no positive results or improve the respiratory system and shown that this practice can have a positive effect on the respiratory system and spirometric indices.
