The effect of implementing an exercise program with blood flow restriction on clinical and functional factors of chronic obstructive pulmonary disease patients at Masih Daneshvari Hospital

A clinical trial with a control group, with parallel groups, without blinding, randomized, phase 3 on 20 patients. A table of random numbers was used for randomization.

The current study is a clinical trial on chronic obstructive pulmonary disease(COPD) patients referred to Masih Deneshvari Hospital in Tehran. Patients are randomly divided into two groups. A six-minute walk test, sit to stand and dynamometry were performed, then the patients of the intervention group were given breathing exercises, including diaphragmatic breathing and chest expansion, and then for 20 minutes with BFR with low load intermittently from a stationary bicycle. use. In the control group, patients only do breathing exercises.

Inclusion criteria include patients with stable chronic obstructive pulmonary disease, able to perform aerobic exercise, between the ages of 40 and 65 years, and exclusion criteria include • sickle cell anemia, history of venous thromboembolism, patients with cancer (mass), patients with hemoptysis, Patients with pulmonary abscess, patients with fibrosis, immunocompromised patients, patients with cardiovascular system instability.

In the intervention group, training of breathing exercises including diaphragmatic breathing and chest expansion and then intermittently using a stationary bike for 20 minutes along with blood flow restriction (BFR) with low load. In the control group, patients only do breathing exercises.

The randomization method is Random Permuted Blocks. For this purpose, two treatment groups A and B are defined as groups AB and BA. Then random table numbers are defined in the range of 0 to 9. We consider numbers 0 to 4 for block AB and numbers 5 to 9 for group BA. Then random numbers are selected from the table. The number 0 is related to block AB, and after that two people enter this block, the first person receives treatment A and the second person receives treatment B. In the same way, for other people, groups are treated. Although in this method, the number of observations of both groups will be the same, but due to the small size of the blocks, the possibility of predicting the treatment group by the person performing it is high. To solve this problem: the randomization list will be done bilaterally before the start of the study by a person outside the treatment staff. It also increased the block size. In the example, blocks with two treatments and 20 patients are designed.
