Background: Cerebral palsy (CP) is a collection of motor disorders caused by brain damage that occur before, during or after birth which can be caused by many factors such as, congenital, genetic, inflation, infection and poisoning during pregnancy, trauma and metabolic disorders. Children with cerebral palsy will mostly have problems with posture. Muscular spasticity found in CP children is not only found in the muscles of the limbs but also the muscles forming posture (body posture), the condition of the body shape of children with CP will be exacerbated by the omission of postures that are not functional. Taping provides convenience in initiating motion, to help people with CP be able to move easily. The objectives of this study is to determine the effect of giving correction posture taping to the ability of motion of cerebral palsy children. Methods: The design in this study is a quasi experiment with a pretest and posttest design. The research will be conducted on the CP community in Yogyakarta, namely the Wahana Cerebral Palsy Family (WKCP) for 8 weeks. The research instrument used in this study was a blank check on the basic functional ability of GMFM. Results: After getting treatment in the form of Correction Posture Taping for 8 consecutive weeks, there was an increase in the functional ability of motion during sleep by 5.1385 with P = 0.000 (α <0.05), when seated by 1.0254 with P = 0.000 (α<0.05), when crawling by 0.44 with P = 0.000 (α <0.05), when standing and walking by 0.6523 with P= 0.000 (α <0.05), when crawling by 0.32 with P = 0.000 (α <0.05). Conclusion: Based on the results of research and the results of data processing, there is the effect of posture taping correction on the functional ability of children with cerebral palsy.
