Background: Coronavirus 19 (covid-19), known as SARS-COV-2, is a new coronavirus with a global epidemic. Physiotherapy is one of the helpful treatments for this disease. This study was conducted with the aim of the effect of priority and delay of the prone positioning and chest physiotherapy (CPT) in patients with covid-19.
Methods: A randomized clinical trial was conducted on 26 patients with covid-19. Patients were randomly divided into two groups: The priority of the prone positioning over CPT (7 men and 6 women, with an average age of 67.46±5.91) and the priority of CPT over the prone positioning (8 men and 5 women, with an average age of 68.38±5.85). Respiratory outcomes including SpO2, PaO2, FiO2, FEV1, FVC, measured by the pulse oximetry, ABG, and spirometry, respectively, and FEV1/FVC, and SpO2/FiO2 ratios were assessed before and after the intervention.
Results: The demographic characteristics of the patients and the respiratory outcomes at baseline between the two groups were not significantly different (P> 0.05). In each group, a significant difference was observed between the respiratory outcomes before and after the intervention (P< 0.05). But after the intervention, there was no significant difference between the two groups in respiratory outcomes (P> 0.05).
Conclusion: Both the priority of the prone positioning over CPT and the priority of CPT over the prone positioning could improve each respiratory outcome. However, it was not observed that the priority or delay of the prone positioning and CPT can affect the improvement of respiratory outcomes in covid-19 patients.
