Abstract
The purpose of this study was to determine the effect of specific strength training program for knees and ankles muscles on ventilatory functions in children with Down syndrome. The study was conducted on 30 children of both sexes (6 girls, 24 boys) with down{u2019}s syndrome who were selected from National Institute for motor rehabilitation. Their ages ranged from 9 to 14 years. They were divided into two equal groups (control and study group). Children in control group (A) received chest physiotherapy program while children in study group (B) received the same chest physiotherapy program in addition to strength training program to knees and ankles muscles by using universal exercise unit. The treatment program was conducted at National Institute for motor rehabilitation for 3 times per week for 3 successive months. Both groups were evaluated by (Zan - 680) ergospirometry which assess ventilatory functions (FVC, FEV1, FEV1 / FVC, MVV) pre and post application of treatment in Mataria teaching hospital. The pre treatment results of this study showed that there were no significant differences in all measured ventilatory parameters (FVC, FEV1, FEV1 / FVC ratio, MVV) among both groups of children. Upon comparing the pre and post treatment results of the present study for both groups, significant differences were recorded within and between groups in the measured ventilatory functions, significant improvement was recorded in certain ventilatory functions (FVC) in study group. Significant improvements were recorded in other ventilatory functions (FVC, FEV1, FEV1 / FVC, MVV) in favor of control group. The post treatment results of both groups revealed that there were significant improvements in the measured ventilatory functions (FEV1, MVV) in favor of control group. So it was concluded that a specific strength training program for lower extremities muscles has no significant effect on ventilatory functions
