The Effect of Home-based Exercise on Functional Capacity of Covid-19 Survivor With Cardiovascular Comorbidity

The Effect of Home-based Breathing and Chest Mobilisation Exercise on Cardiorespiratory Functional Capacity of Covid-19 Survivor With Cardiovascular Comorbidity

Objective propose: to investigate the effect of home based breathing exercise and chest mobilization on the cardiorespiratory functional capacity of Covid-19 survivors with cardiovascular comorbidity. Breathing exercise and chest mobilization are proven to increase lung functional capacity in Covid-19 survivors. It is hypothesized that breathing exercise and chest mobilization in Covid-19 survivors will give benefits to Covid-19 survivors with cardiovascular disease.

Lung restrictive disorder is one of the reasons that induce chronic fatigue in COVID-19 (Corona Virus Disease-19) survivors. It also gives a significant effect on cardiovascular patients who are in the second phase of cardiac rehabilitation. Breathing exercise and chest mobilization are proven to increase lung functional capacity in Covid-19 survivors. On the other hand, there is still no research that shows the effectiveness of Breathing exercises and chest mobilization in Covid-19 survivors who are suffering from cardiovascular problems. Patients in National Cardiac Center Hospital, Jakarta, with a history of Covid-19 and have cardiovascular disease are recruited. They will undergo pre and post-exercise examinations such as blood sampling, do 6 minutes walking test, Peak Cough Flow and Peak Flow Rate test, measuring the chest dimension, treadmill, and answer the European Quality of Life Five Dimension (EQ-5D) questions. With randomization, patients will be determined to treatment or control group. They will be prepared about what exercises should they do at home. Subjects will be supervised digitally and regularly through Zoom meetings. Exercises will be done for 3 months.

Patients will do the second phase of cardiac rehabilitation for minimum 5 times per week, 30 minutes each time, in 3 months without being supervised

Patients will do the second phase of cardiac rehabilitation for minimum 5 times per week, 30 minutes each time and breathing and chest mobilization exercise for 3 times per week. They will be supervised through online meetings.

Patients walk regularly 5 times per week and increase the distance day by day according to their improved ability. Patients also do breathing and chest mobilization exercise 3 times per week. It is a recorded moderated exercise for 30 minutes duration. Patients can access the video as a home-based activity through an online videos platform and will be supervised.

Independently, patients walk regularly 5 times per week and increase the distance day by day according to their improved ability without breathing and chest mobilization exercise.

To define initial ability to walk in 30 minutes for second phase cardiac rehabilitation (aerobic exercise). Unit of measure : meter

1=have no problem, 2=have slight problem, 3=moderate problem, 4=severe problem, 5=unable to do. We will compare the points between pre and post exercise and looking the improvement.

Inclusion Criteria: Patients who got infected by Covid-19 in 3 months before recruitment and suffering cardiovascular disease Able to communicate and operate Youtube and Zoom. Exclusion Criteria: Limitation to move any part of the body that causes the inability to do the instructed exercise. Feel pain in extremities (visual analog scale >3) Chronic Obstructive Pulmonary Disease Neuromuscular disorder (stroke, peripheral neuropathy with significant motoric control disturbance Musculoskeletal disorder (fracture, post amputation, severe arthritis in support joints)
