Abstract
[Purpose] To investigate the effects of combined chest expansion and breathing exercises in a patient with sternal pain. [Subject and Methods] The study subject was a 36-year-old female employed as a babysitter who complained of sternal pain at the T1-4 level. The subject performed the combined chest expansion and breathing exercises. [Results] The thoracic kyphosis angle after combined chest expansion and breathing exercises decreased compared with the initial angle. The sternal pain after these exercises also decreased compared with the initial value. [Conclusion] This study suggests that combined chest expansion and breathing exercises can be effective in treating sternal pain.
