Coronary artery disease is single of the most debilitating forms of cardiovascular disease, affecting across 12 million people in the United States.1 Coronary artery bypass (CAB) surgery is a standard intervention to revascularize the heart in patients with coronary artery disease. In 1997 approximately 600000 CAB steps were performed which is a 432% increase since 19791 In addition to this increase in the number of CAB steps performed the type of surgical avenue for this procedure has changed in modern years. Newer surgical techniques for patients with coronary artery disease have substantially reduc hospital long duration of stay.2 It is not strange for patients to be discharged from the hospital in les than a week after heart surgery2-4 Earlier hospital discharge makes it especially important for patients following CAB surgery to receive follow-up rehabilitation services. frequently this need is addressed by means of participation in an outpatient (phase II) cardiac rehabilitation program. Unfortunately, les than half of all patients that are eligible for outpatient cardiac rehabilitation actually enlist in a program after hospital discharge.5-7 Limited accessibility (transportation, distance, winter weather) to outpatient cardiac rehabilitation services may restrict many patients following CAB surgery from receiving rehabilitation after hospital discharge.8,9 proper to multiple impairments and functional limitations (see Table 1) patients may also ne physical therapy services outside of the end of traditional outpatient cardiac rehabilitation. As a deduction of these factors, patients recovering from CAB surgery are frequently treated by physical therapists in outpatient clinics, household health settings, and inpatient rehabilitation facilities.10

Surgical inlet Procedures

Traditionally, most numerous CAB procedures have been performed using a median sternotomy surgical access This approach involves incising the skin and subcutaneous tissue overlying the breastbone sawing longitudinally through the manubrium, material substance and xiphoid process of the sternon and cutting into the pericardial sacs. This surgical ingress does not typically incise any skeletal muscle, if it be not that requires mechanical separation of the sternal halves to detect the heart.11 This mechanical separation of the sternal halves places abnormal forces forward the anterior and posterior articulations of the ribs. Median sternotomy provides optimal aspect of the heart for surgical manipulation and spares skeletal muscle direct incisional trauma. Surgical closure of the breastbone is often accomplished with stainless carbonized iron wires, but other techniques are being investigated. lately Cohen and Griffin evaluated the biomechanical properties of 3 different sternotomy closure techniques, stainless-steel figure-of-eight wires, figure-of-eight cables, and dynamic fixation plates. They construct that the plate and cable combination of parts to form a wholes were superior to the wire rule especially during transverse and longitudinal forces. In addition, the plate theory substantially reduced cutting into the sternal pattern as compared to the wire and cable plans during distraction and longitudinal forces.12

Minimally invasive surgical access techniques have been unraveled to offer an alternative to traditional CAB performed using a median sternotomy. There are 2 primary variations of minimally invasive surgical access for CAB, left anterior small thoracotomy (MIDCAB), and port-access (PACAB). The MIDCAB operation most commonly involves a limited anterior 4th or 5th intercostal incision. lately Oliveira et al described variations in the MIDCAB transaction by location and frequency and their findings are illustrated in Figure 113 This original of surgical entry results in incision of the intercostal, pectoral is major, and/or pectoralis minor muscles and sometimes the lower portion of the breastbone MIDCAB procedures usually are limited to a single bypass of the left anterior descending artery using the left internal mammary artery forward a beating heart. The PACAB practice uses endoscopic technology. Several small incisions, or ports, are created forward the anterior chest wall in the intercostal spaces to allow viewing and manipulation of the heart. This shadow of surgical entry results in incision of the intercostal, pectoral is major, and/or pectoralis minor muscles. This performance can involve single or multiple coronary bypasses usually forward an arrested heart with peripherally inserted cardiopulmonary bypass.14,15

Early studies have reported improved morbidity rates and shortened hospital detail of stay with minimally invasive surgical access conducts but little is known about functional outcomes16-21 Arom and associates compared immediate postoperative results in 3 groups of patients MIDCAB, median sternotomy with beating heart (OPCAB), and median sternotomy using cardiopulmonary bypass (CPB-CAB) which allowed evaluation of the independent influences of cardiopulmonary bypass use and median sternotomy surgical access.16 They originate significant differences among groups for posterity loss (MIDCAB OPCAB = CPB-CAB).16 Use of a smaller surgical incision is idea to reduce postoperative pain unless little objective evidence exists to demonstrate this presumption.14 Median sternotomy has been shown to cause restrictive pulmonary dysfunction in patients following CAB surgery2223 Guler et al evaluated the efficiency of CAB surgical procedure in patients with chronic obstructive pulmonary disease. They fix differences in extubation time and intensive care unit longitudinal dimensions of stay (MIDCAB
