The activity monitor obtains a first set of physical activity data over a first time period, eg, daytime, and a second set of physical activity data over a second time period, eg, night It is configured as follows. The processor processes the data obtained by the activity monitor and calculates the physical activity ratio. The physical activity ratio is the ratio of physical activity measured during the first time period to physical activity measured during the second time period. The processor also calculates a first overall value representing the activity level of the subject during the first time period. Physical activity ratio, together with the first overall value, to assess the severity of COPD symptoms presented by the subject, or psychological complications such as low motivation presented by the subject Can be used to identify physical problems or sleep quality problems.
