The effect of eight-weeks corrective games on kyphosis angle and postural control in mentally retarded children having kyphosis

Mental retardation is one of the most common mental disabilities that are allocated about 3% of the world's population. The purpose of this study was to examine the effect of eight-weeks corrective games on kyphosis angle and postural control in mentally retarded children having kyphosis. Thirty mentally retarded female children with Hyper kyphosis (increase in thoracic curvegreater than 40 angle) were selected and randomly divided into two groups; experimental group (N=15) and control group (N=15). The angle of kyphosis was measured by using a flexibleruler. However the BIODEX Balance System (BBS) was used to evaluate the static and dynamic postural control of performance. The Experimental group played the corrective games for eightweeks (three sessions per week) while during this period control group did not experience any exercises. To analyze the data independent and dependent T test were used. The results of theresearch showed that corrective games had a significantly positive effect on kyphosis angle and all directions of postural control in the static and dynamic states among mentally retarded children.So it can be concluded that performing corrective exercise may be effective in the improvement of kyphosis angle among mentally retarded children.
