About

The aim of the study is to investigate the effects of an upper limb cycle ergometer in phase I CABG patients. This will likely enhance various outcomes such as quality of life, dyspnea, functional outcome measure, cardiovascular parameters, and upper limb mobility. If utilized, the arm ergometer may contribute to improve upper limb strength and endurance. This could result in improving upper limb range of motion and reducing the risk of adhesive capsulitis. This study will positively impact society by reducing morbidity and mortality rates, healthcare costs and ultimately improves patient care.

Full description

The most often done major surgical surgery is coronary artery bypass grafting (CABG), a significant surgical procedure by using harvested venous or arterial conduit to bypass atheromatous obstructions in a patient's coronary arteries. Following heart surgery, patients face many complications that increases the duration of stay in the intensive care unit (ICU) and hospital, as well as the death rates following surgery. Following coronary artery bypass grafting (CABG), compliance with the cardiac rehabilitation (CR) regimen is essential. Cardiac rehabilitation in phase I include mobilization, respiratory and physical exercises, education on heart disease risk factors, and stress and anxiety management. An apparatus designed to help physiotherapists to increase muscle training is the upper limb cycle ergometer. It is possible to execute cyclical rotations with this equipment and utilize it for resistive, active, and passive patient exercise. Patients who have had coronary artery bypass surgery report improved physical and psychosocial functioning after engaging in arm ergometer workouts. The aim of this study is to investigate the effects of phase I cardiac rehabilitation on quality of life, dyspnea, functional outcome measure and cardiovascular parameters with and without upper limb cycle ergometer in immediate post-operative period of CABG.

A randomized clinical trial will be conducted at Combined Military Hospital Lahore. Non-probability convenient sampling technique will be applied on the patients according to the inclusion criteria. Patient will be randomly allocated through lottery method into group A and group B to collect data. Group A will receive upper limb exercise on arm ergometer lasting 5 min at 30 rpm (rotation per minute) 3 times a day for 7 days and standard treatment which includes breathing exercises, active upper and lower exercises (3 sets of 10 repetitions daily for 7 days); ambulation within the inpatient wards for 6 min, transfer to chair (allocated at the side of bed sitting for 30 min), that will be progressed as patient condition till 7th day. Group B will receive same standard treatment as above, but without arm ergometer. The study will be completed within the time duration of ten months. Treatment evaluation of patients will be done after one week through 36-Item Short Form Survey (SF-36), Modified Medical Research Council Dyspnea scale, and Functional Independence Measure scale. Data will be analyzed using SPSS software version 27. After assessing normality of data by Shapiro-wilk test, it will be decided either parametric or non-parametric test will be used within a group or between two groups.
