The Effects of Pulmonary Physiotherapy Treatments on Patients With COVID-19
Study Details
Study Description
Brief Summary
The aim of this study is to evaluate the efficacy of pulmonary physiotherapy on respiratory functions in hospitalized patients with Novel Coronavirus 2019 pneumonia. Patients will be randomized into 1) intervention group: receiving pulmonary physiotherapy technique to improve pulmonary function and walking training or 2) control group: Usual medical care. Patients in both groups will receive therapeutic incentive spirometer. Various outcome measurements of pulmonary functions will be evaluated before and after of interventions. Mortality rate, hospitalization duration and re-admission will be followed until one month after end of intervention. Also, patient's quality of life will be measured after one month.

Detailed Description
In late December 2019, the new coronavirus (COVID-19) emerged in Wuhan, China and it has been confirmed as the cause of pneumonia in a large number of Chinese patients. The virus, also known as SARS-CoV-2, has since then spread to more than 200 countries worldwide.
The most common symptoms of COVID-19 are fever, dry cough, shortness of breath and tiredness. In severe cases, the infection could cause pneumonia, acute respiratory distress syndrome (ARDS) and sometimes leads to death. Pulmonary physiotherapy is a comprehensive, effective and safe treatment method which is aimed at improving patient's respiratory symptoms, train effective coughing, clear the airway secretion, eliminate exacerbation and so on. It seems that pulmonary physiotherapy interventions can effectively decrease hospitalization, reduce the risk of complications and improve the patient's medical condition.
The aim of this study is to evaluate the effectiveness of the hold breathing technique, chest expansion exercise, postural drainage procedure and Cough techniques carried out during pulmonary physiotherapy sessions.
The researchers will invite 40 hospitalized patients in Imam Khomeini Hospital Complex, Tehran, Iran. All patients will be enrolled after taking informed consent. All of the procedure will be performed with the coordination of the patient's physicians. Patients will be randomized to the intervention or control group. Primary outcome measurements will be evaluated immediately before and after the interventions (with three days period). Also, patient's condition (including process of disease progression, mortality, hospital stay duration and re-admission) will be followed until one month using medical records review and interviewing with the patient or his/her family. Patient's health related quality of life will be measured using short form-36 quality of life assessment tool one month after the end of interventions. Intention-to-treat analysis will be performed in the patients that dropped out of the study.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Pulmonary Physiotherapy Techniques group Pulmonary physiotherapy techniques, 6 sessions during 3 days and incentive spirometer. |
Other: Pulmonary Physiotherapy Techniques
Participants will receive pulmonary physiotherapy techniques in six session during three days (twice daily). Four distinguished interventions will be provided for the patients: 1) Chest expansion exercises (for prevention and treatment of potential atelectasis); 2) Techniques to Mobilize or loosen the pulmonary secretions (Active cycle breathing, Coughing techniques, Vibration and Postural drainage); 3) Hold breathing exercise (3 sets, 10 repetition) and; 4) Walking training (based on patient's tolerance until 6 minute).

Secondary Outcome Measures

The number of dead subjects compared to total patients
- Number of participants with Rehospitalization [until one moth]
Patients' hospitalization after discharge due to any reason
- The Health-Related Quality of Life (HRQOL) [One month after end of intervention]
Using Short-form 36 questionnaire. The minimum score is 0 and the maximum score is 100. Higher scores mean patient's better quality of life.
- breathlessness [Baseline]
The amount of shortness of breath using Visual Analogue Scale (VAS). The minimum score is 0 and maximum is 10. The 0 score means no breathlessness and the 10 score is the maximum breathlessness.
- breathlessness [Day 3]
The amount of shortness of breath using Visual Analogue Scale (VAS). The minimum score is 0 and maximum is 10. The 0 score means no breathlessness and the 10 score is the maximum breathlessness.
