This study aims to evaluate the clinical efficacy of breath-guided improvement of COPD exercise ability, establish a breath-guided rehabilitation program of intelligent iot and remote home, improve COPD exercise ability, reduce acute exacerbation, and form high-quality clinical evidence.
Patients with COPD in stable stage
Patients with grade 2 to 4 lung function
Age 40~80 years old
Be able to use smart phones, computers and other devices independently or with the help of family members during home training
Pregnant or lactating women and patients with recent pregnancy plans
Delirious, dementia, all kinds of mental illness
Tumor patients who have undergone resection, radiation, and chemotherapy within 5 years
Patients with severe osteoarthropathy or osteoporosis, unstable fractures
Parallel
Breathing guided exercise
BehavioralBreathing guided exercise are divided into six sections: relaxing standing, two fields breathing, regulating lung and kidney, turning side finger, running kidney hall and nourishing qi and collecting gong. Exercise time: 5 days a week, 1 to 2 times a day, a total of 24 weeks.
Flat walking training
BehavioralFlat walking training can be performed either outdoors or on flat indoor surfaces at a steady pace of 80 to 120 steps per minute for at least 30 minutes each session, raising the heart rate to the target range and maintaining it for over 10 minutes. This should be done 3 to 5 times a week, with 1 to 2 sessions each day, for a total of 24 weeks. The intensity of the exercise is moderate. The target heart rate based on heart rate reserve is calculated as (maximum heart rate during exercise - resting heart rate) × (40-60)% + resting heart rate.
6 Minutes Walking Distance Test (6MWD)
The 6-minute walking distance of the two groups was calculated
Incidence of acute exacerbation
The proportion of patients with ≥1 acute exacerbation in each group during the study period was recorded. If the interval between two acute exacerbations was within 5 days, it was considered as 1 acute exacerbation.
Degree of breathing difficulty
The modified Medical Research Council dyspnoea scale (mMRC) will be used to assess severity of dyspnea. The mMRC scale is a 4-point (0-4) scale. "0" means no dyspnea perception, "4" means severe dyspnea perception.
Borg dyspnea score
Borg dyspnea score is a 10-point (0-10) scale based on the severity of dyspnoea. "0" means no dyspnea perception, "10" means most severe dyspnea perception.
The COPD Assessment Test(CAT)
The COPD Assessment Test (CAT) is an 8-item questionnaire that assesses health status in patients with COPD. The questionnaire uses a 0-5 point scale, with higher values indicating a greater impact of COPD on the patient.
