Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cardiopulmonary exercise testing device	The machine analyze the breath of participants including oxygen consumption and minute ventilation volume. Oxygen consumption is reported in mL/min and minute ventilation volume is reported in L/min.	baseline
Primary	Surface electromyography device	The surface EMG is performed to assess the maximum voluntary contraction and muscle activity of upper limb muscles and accessory inspiratory muscles during performing simulated ADL tasks. The maximal voluntary contraction (MVC) is used as the reference level of muscle activity to normalize the EMG data of performing simulated ADL tasks. The muscle activity is reported in percentage.	baseline
Primary	The clinical Chronic Obstructive Pulmonary Disease questionnaire	This is a self-reported questionnaire to measure the impact of COPD on participants' health status. The rating scores is a 7-point scale (0=no limitation, 6=totally limited).Higher scores mean the more severe impact of COPD on participants' daily living.	baseline
Primary	Modified Borg Scale	This is a self-reported scale to measure how much participants perceive dyspnea. The range from 0 which means no difficulty to breathe to 10 which means with maximal difficulty to breathe.	baseline
Primary	Modified Medical Research Council	This is a five-point scale to assess the severity of breathlessness.	baseline
Secondary	EQ-5D questionnaire	This is a self-reported questionnaire for measuring generic health status	baseline
