The aim of the study was to show the effect of foam roller exercises on the deviation of back curvature among the female students. The researcher chose students from the age stage 9-12 years of , Cambridge Language School in Sadat City, the academic season 18/2019, with severe kyphosis deviation. Method: The researcher used the experimental method, through the experimental design of the measurement (pre- and post-test) for one experimental group, due to its relevance to the nature of the research application and its procedures. Results: The proposed rehabilitation program using a foam roller for the research sample led to a positive improvement in the Kyphosis deviation and the rotation of the shoulders, and the physical variables flexibility, ability, speed and agility, with statistically significant differences at the 0.05 level in the dimensional measurement. The program led to a decrease in the increase in Kyphosis with a positive improvement approaching the natural convexity of good posture at a rate of (3.82%), and the rotation of the shoulders by (50.0%) and an improvement in the selected physical elements in the research experiment ranged between (10, 23 _ 43.61%)
