Background and Aim: Cerebral palsy (CP) is the most common motor impairment in childhood and affects 2 in 1000 live births, in which postural and motor control involved. In hemiplegic type, two sides of the body have differences in postural tone that cause weight shift to the intact side. In these children postural disorders appear as postural stability disorder. The aim of this study is to assess the effect of lateral wedge insole on postural control in cerebral palsy children.
Materials and Methods:  Sixteen hemiplegic children attended in this program and stood in two conditions on the force plate with and without lateral wedge on the hard plate. Center of pressure displacement measured for medio-lateral and antro-posterio directions. Every test took 20 seconds. It was repeated 3 times.
Results: Range of sideways decreased significantly with use of 5º wedge. Also a shoe wedge of 5º provided symmetrical weight distribution.
Conclusion: The results represent that a 5º lateral wedge applied to the unaffected limb, can improve factors of postural control and gain the symmetry in hemiplegic children
