**5. Conclusions**

Present study was conducted with twenty-five children to determine the effects of FPRE on strength, lower extremity structure, muscle tone, dynamic balance and functional ability in children with spastic cerebral palsy. This study confirmed that FPRE exerts a positive effect by increasing lower extremity strength and morphology of quadriceps muscle, reducing muscle tone and increasing dynamic balance and functional ability in children with spastic CP. Therefore, we sugges<sup>t</sup> FPRE as an effective, safe and convenient intervention that can be implemented in a six-week period in children with CP in rehabilitation.
