The aim of this study was to investigate the effect of treadmill back walking training on balance and function in cerebral palsy.

In our study, scientific data will be prepared by clinical measurement tools in order to determine whether there is balance and walking effect of easy and practicable treadmill back walking training in the clinical setting in Cerebral Palsy.

Measurements will be made at baseline and after each 8 weeks of physiotherapy program, the results will be compared.

30 minutes of the physiotherapy session, which we will apply for 2 days and 45 minutes; in the prone, supine, crawling and above knee positions; They will take physiotherapy training based on neurodevelopmental therapy consisting of fine motor activities, standing up, weight transfer, stretching, strengthening and balance exercises with mat activities such as rotation, weight transfer, sitting.

1. Term: After the first measurements, the participants will take 8 minutes, 2 days a week, the regular physiotherapy session based on 30 minutes Neurodevelopmental Therapy as described above, as well as 15 minutes conventional walking training, then the measurements will be repeated.
2. Term: After the second measurements, the participants will take 8 weeks, 2 days a week, the regular physiotherapy session based on 30 minutes of Neurodevelopmental Therapy as described above, as well as 15 minutes of treadmill back walking training, then the measurements will be repeated.
3. Term: After the third measurements, the participants will take 8 weeks, 2 days a week, the regular physiotherapy session based on the 30 minute Neurodevelopmental Therapy described above, as well as the 15-minute treadmill walking forward training, then the measurements will be repeated.

Statistical method (s) to be used: In the analysis of the results to be obtained in our study, SPS statistics 22.0 version of SPSS statistical package will be used under the Windows operating system Statistical Package for Social Sciences (SPSS). Descriptive statistical information will be shown as arithmetic mean ± Standard Deviation (x statistical ± Ss) or percentage (%) and the level of statistical significance will be considered as p≤0.05.
