Study aim
-
Evaluation of the effect of respiratory physiotherapy on pulmonary function including respiratory capacity, the tidal volume, residual volume, number of breaths, and its frequency while walking on a treadmill, O2-CO2 gas concentration in inhalation and exhalation, parameters related to spirometry In patients with COVID-19 in its recovery period.
-
Design
-
A clinical trial with a control group, with parallel groups, double-blind, randomized, phase 2 on 44 patients. The random table of numbers is used for randomization.
-
Settings and conduct
-
In the next stage, after assigning patients to intervention and control groups, patients in the intervention group are asked to go to the physiotherapy clinic for 10 days a week for 10 sessions and under the supervision of a physiotherapist with at least 10 years experience in respiratory physiotherapy, interventions To receive. The control group receives its routine treatments prescribed by the relevant physician.

-
Patients aged 35-55 years old who have a history of hospitalization due to COVID-19 virus. A minimum of 1 month and a maximum of 2 months have elapsed since discharge from the hospital and a positive PCR test or diagnosis of lung involvement based on CT scan of the lung at the time of hospitalization.
-
Intervention groups
-
Chest physiotherapy intervention:
1- Segmental breathing exercises for lung lobes in lying and sitting position
2- Proper posture (postural drainage)
3- Deep breathing and diaphragmatic exercises
4- Incentive spirometer
5- Controlled movement and movement and breathing exercises while riding a stationary bike
In the control group, after the study phase, 10 sessions of physiotherapy will be performed as mentioned.
