Open label, multicenter trials, non-randomized, single arm, distribution-free test to verify the effectiveness about remote support using a smartphone for keeping physical activity on persons with chronic obstructive pulmonary disease

INTERVENTION: Single arm test. The evaluations about the amount of physical activity and 6‐min walking test are executed before interventions on patients with COPD. After these, we start to intervene that to support their physical activity using a smartphone. We measure their daily walking distance and steps everyday by smartphones, and then sent them feedback messages to their smartphones. The term of interventions is 6 months. After 6 months intervention, the evaluations about the amount of physical activity and 6‐min walking test are re‐executed. We compare change of the data about physical activities and fitness level between pre‐post interventions. CONDITION: Chronic Obstructive Pulmonary Disease PRIMARY OUTCOME: Variation of the amount of physical activity and fitness level by intervention in the remote health support during 6 months. The amount of physical activity is measured by a pedometer. Fitness level is measured by the method of 6‐minute walking test. INCLUSION CRITERIA: Over 20‐year‐old patient with COPD. He/she has a medical examination once a month in National Hospital Organization East Nagano Hospital and keep the steadiness of their disease condition at home. Furthermore, he/she is a parson, who is admitted the eligibility to attend the research by their doctors.
