Effect of sitting and lying Liuzijue exercise for pulmonary rehabilitation in acute exacerbation of chronic obstructive pulmonary disease patients with non-invasive ventilation: a randomized controlled trial.

BACKGROUND: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) will lead to the aggravation of respiratory symptoms and accelerate the progression of the disease. So early pulmonary rehabilitation is essential for patients with AECOPD. We aimed to investigate the effect of sitting and lying Liuzijue in AECOPD patients with non-invasive ventilation. METHODS: A total of 80 AECOPD patients with non-invasive ventilation were randomly divided into two groups. The controlled group (CG) (n=40) received AECOPD conventional treatment and nursing, and the sitting and lying Liuzijue exercise group (LG) (n=40) received sitting and lying Liuzijue therapy. Participants in the LG were required to take this training for 3 months, 30 minutes once every morning and evening. Pulmonary function test, 6-minute walking test (6MWT), Modified Medical Research Council Dyspnea Scales (mMRC), and the St George's Respiratory Questionnaire (SGRQ) were evaluated before and after the intervention. Blood gas was measured before treatment, 3 days, and 5 days after treatment. In addition, the length of hospital stay, the duration of non-invasive ventilation, and the frequency of acute exacerbation within 6 months after the intervention were compared. RESULTS: Seventy patients completed the study. The pulmonary function, 6MWT, mMRC scores, SGRQ, and pH, were significantly improved in the LG. Meanwhile, the 6MWT of the CG was improved. The comparison between the groups showed that the improvement of the pulmonary function, 6MWD, mMRC scores, SGRQ, the duration of non-invasive ventilation, and the frequency of acute exacerbation within 6 months of the LG group differed significantly from the CG. CONCLUSIONS: Sitting and lying Liuzijue exercise methods significantly improved lung function, exercise endurance, and quality of life in AECOPD patients with non-invasive ventilation.

Effect of sitting and lying Liuzijue for lung rehabilitation in acute exacerbation of chronic obstructive pulmonary disease patients with non-invasive ventilation: Study protocol for a randomized controlled trial.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a lung disease with the highest incidence and high mortality in the world. Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) can significantly accelerate the progression of the disease. Pulmonary rehabilitation is one of the effective treatment methods in COPD patients, but few studies have focused on the effect of pulmonary rehabilitation in AECOPD patients. Liuzijue can improve the pulmonary function and relieve symptoms of COPD patients. However, due to the influence of disease and non-invasive ventilation (NIV), AECOPD patients have poor compliance with getting out of bed at the early stage. Sitting and lying Liuzijue is more suitable in AECOPD patients with NIV. Therefore, this study will evaluate the effect of sitting and lying Liuzijue for lung function, exercise endurance, and quality of life in AEOPD patients with NIV. METHODS: This study is a clinical randomized controlled trial. Sixty four AECOPD patients with NIV will be randomly divided into the experimental group and the control group. All participants will be treated with routine treatment and nursing according to their specific condition. The experimental group will be combined with sitting and lying Liuzijue on the basis of the control group. The duration of the exercise will be 3 months. The primary outcomes are the pulmonary function test and 6-minute walking test (6MWT). The secondary outcome measures include blood gas parameters, dyspnea index (the Modified Medical Research Council Dyspnea Scale [mMRC]), the body-mass, airflow obstruction, dyspnea and exercise capacity (BODE) index, anxiety, and depression (Hospital Anxiety and Depression Scale [HADS]), and quality of life (St·George Respiratory Questionnaire [SGRQ]). The measurement of outcomes will be evaluated at week 13. DISCUSSION: It's imperative to focus on pulmonary rehabilitation in AECOPD patients. The purpose of this study is to evaluate the effect of sitting and lying Liuzijue for pulmonary rehabilitation in AECOPD patients with NIV.
