Background: Chest expansion is the important tool to determine the patient’s status and the respiratory function. The stretching technique performed on foam roller (self-myofascial release) helps in lengthening the muscles by releasing its tightness and soreness and hence enhances the chest expansion. This study concentrates on the immediate effect of foam roller stretch on chest expansion. Objectives: The purpose of this study is to determine the immediate effect of foam roller stretch on chest expansion. Methods: Cross- sectional study of 50 convenient sampling based on gender distribution. Results: The results were obtained using foam roller and individual chest expansion. Statistical analysis shows that there is significant increase in upper level (p=0.000), middle level (p=0.000) and lower level (p=0.000) in the thoracic region. Conclusions: There is significant increase in chest expansion after foam roller stretch.
