After recruitment in the AECOPD admission, baseline assessment will be done 24 hours before discharge from hospital. Each subject will then be followed up every 3 months after discharge for 1 year. For the intervention group, the PRP will start within 10 days of discharge from the hospital. Patients in the intervention group will attend the rehabilitation unit in our physiotherapy department on 3 half days per week for 6 weeks. In the first visit, the patient will be seen by a nurse specialist and offered smoking cessation counseling and inhaler technique will be reinforced. The nurse will also offer psychosocial support to the patient. The exercise sessions will be performed by 2 dedicated physiotherapists. Supervised exercise training includes use of treadmill, arm cycling, and arm and leg weight training will be provided with intensity adjusted by the physiotherapist based on the tolerability and physiological variables (oxygen saturation and heart rate) of the patient. Patients will also be advised to perform home exercises. The physiotherapist will also teach the patient on proper breathing techniques and how to cope with the daily activities.
