The importance of the research and the need for it lies in the following:
* Shed light on the wrong habits of schoolgirls in the age group of 9-12 years, which cause deviations in morphology, especially hunched back.
* Using easy-to-use foam roller exercises to treat and reduce kyphosis for girls in puberty.
*The proposed program may help in the treatment of back curvature, which reflects positively on the motor and physical performance of the students of this stage.
The research aims to design a rehabilitation exercise program using a foam roller to identify :
1-The effect of foam roller exercises on the deviation of back curvature among the female students, the research sample.
2-The relationship between the deviation of back hump and the rotation of the shoulders and some physical variables among the female students in the research sample.
3-The percentages of improvement in the skewness of the back curvature and the rotation of the shoulders, and some physical variables among the female students in the research sample.
Research Methodology:
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.
Research sample community:
The research community is represented by the students of Cambridge Language School in Sadat City, the academic season 18/2019, and the research sample was chosen in a deliberate way from the students in the age stage from 9-12 years with increased dorsal curvature deviation, and the basic sample was (20) students, and the researcher chose (20) students from the same age group in the school, and from outside the basic sample to conduct the survey studies.
