A computer program comprising instructions which, when the program is executed by a computer, cause the computer to execute the following processes: • acquiring motion information as an electrical motion signal relating to motion of respiratory muscles or accessory respiratory muscles from a detection sensor that detects the motion information; • acquiring action potential information relating to the respiratory muscles or the accessory respiratory muscles from an electromyogram sensor that acquires the action potential information; • determining whether a first condition is satisfied on the basis of the acquired motion information; • determining (S02, S04) whether the acquired action potential information corresponding to the expiratory muscles is equal to or higher than a predetermined threshold; • outputting information relating to exacerbation in chronic obstructive pulmonary disease (COPD) in a case where the first condition is satisfied and the acquired action potential information corresponding to the expiratory muscles is equal to or higher than the predetermined threshold; • determining that the first condition is satisfied in a case where a maximum value and/or a minimum value of the electrical motion signal which is output by the detection sensor continue/s to increase by a predetermined amount or more for a predetermined time; • wherein the electrical motion signal is a voltage; and • wherein said continuing increase is determined by: ∘ extracting the voltage maxima for the predetermined time in a time-series manner, ∘ calculating a slope of a first trend line formed by the extracted maxima, and ∘ if said slope exceeds a first predetermined slope threshold, determining that the first condition is satisfied, and/or • wherein said continuing increase is determined by: ∘ extracting the voltage minima for the predetermined time in a time-series manner, ∘ calculating a slope of a second trend line formed by the extracted minima, and ∘ if said slope exceeds a second predetermined slope threshold, determining that the first condition is satisfied; • wherein the first and second trend lines illustrate a temporal change in a voltage which is output from the detection sensor. • acquiring motion information as an electrical motion signal relating to motion of respiratory muscles or accessory respiratory muscles from a detection sensor that detects the motion information; • acquiring action potential information relating to the respiratory muscles or the accessory respiratory muscles from an electromyogram sensor that acquires the action potential information; • determining whether a first condition is satisfied on the basis of the acquired motion information; • determining (S02, S04) whether the acquired action potential information corresponding to the expiratory muscles is equal to or higher than a predetermined threshold; • outputting information relating to exacerbation in chronic obstructive pulmonary disease (COPD) in a case where the first condition is satisfied and the acquired action potential information corresponding to the expiratory muscles is equal to or higher than the predetermined threshold; • determining that the first condition is satisfied in a case where a maximum value and/or a minimum value of the electrical motion signal which is output by the detection sensor continue/s to increase by a predetermined amount or more for a predetermined time; • wherein the electrical motion signal is a voltage; and • wherein said continuing increase is determined by: ∘ extracting the voltage maxima for the predetermined time in a time-series manner, ∘ calculating a slope of a first trend line formed by the extracted maxima, and ∘ if said slope exceeds a first predetermined slope threshold, determining that the first condition is satisfied, and/or ∘ extracting the voltage maxima for the predetermined time in a time-series manner, ∘ calculating a slope of a first trend line formed by the extracted maxima, and ∘ if said slope exceeds a first predetermined slope threshold, determining that the first condition is satisfied, and/or • wherein said continuing increase is determined by: ∘ extracting the voltage minima for the predetermined time in a time-series manner, ∘ calculating a slope of a second trend line formed by the extracted minima, and ∘ if said slope exceeds a second predetermined slope threshold, determining that the first condition is satisfied; ∘ extracting the voltage minima for the predetermined time in a time-series manner, ∘ calculating a slope of a second trend line formed by the extracted minima, and ∘ if said slope exceeds a second predetermined slope threshold, determining that the first condition is satisfied; • wherein the first and second trend lines illustrate a temporal change in a voltage which is output from the detection sensor.
