Physiotherapy can help patients at various stages of COVID-19 infection and recovery. It is used in ICUs to help clear secretions and prevent complications in ventilated patients. Techniques include positioning, chest physiotherapy, and limb exercises. For non-ICU patients, physiotherapy focuses on breathing exercises, coughing, postural drainage, and mobilization. After leaving hospital, regular exercise can aid recovery through improving fitness, reducing breathlessness, and increasing muscle strength. A physiotherapy program includes warm-up, fitness, strengthening, and cool-down exercises.
