Methods: 120 patients of both sexes who had acute sternal instability post-open heart surgery will be recruited in this study at Assiout University Hospitals; their ages will be \> 18 years. They will be randomly assigned into 4 equal groups: 1. Study group (A): patients will receive supra-abdominal resisted exercises combined with LLL and the traditional cardiac rehabilitation program of phase one. 2. Study group (B): patients will do infra-abdominal resisted exercises combined with LLL and the traditional cardiac rehabilitation program of phase one. 3.
