Comparison of Supra-abdominal ex Versus Infra-abdominal With Laser on Median Sternotomy

Summary

the aim of this study is to find out the differences between the effect of supra- abdomen exercises and the effect of infra-abdomen exercise combined with LASER And the effect of LOW LEVEL LASER only on sternal instability. 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. Study group (c): patients will receive a traditional cardiac rehabilitation pro-gram of phase one with LLL
4. Control group: patients will receive the traditional cardiac rehabilitation pro-gram of phase one only

BEHAVIORAL

patients will receive Traditional cardiac rehabilitation program of phase one with LLL

A probe laser device will be usedat median sternotomy site. at a distance of 2 cm from each other, for a total of five to eight points. the device will be placed in a perpendicular position to the sternum each spot for 60 sec for a total session time of 5-10 min. Each patient will receive one session daily, three times a week, for four consecutive weeks:•Treatment time per point (s) 60•Laser beam Class :3B•Laser Type :Semiconductor GaA.Modes of Operation :Continuous Pulse upto 5 khz.•Wave Length: 685nm•Maximum Probe Power: 500 mw•Power Density:0.8w/cm2•Max Energy within 1 min 2.4 Joules•Number of spots 8 Patients will be instructed to perform deep breathing using incentive spirometry in the form of four sets, each consisting of 10 deep breaths for a total of 40 deep breaths, with a hold at the end of inspiration, then huffs and coughs with the support of pillows at the incision. The patients will be instructed to follow sternal precautions
