Background and Aims: Patients with COPD exhibit persistent dyspnoea in daily activities and irreversible airflow obstruction. These will finally lead to inability to carry on daily activities and markedly decrease their quality of life. Endurance and strength training was now considered as therapy modality to alleviate several symptoms experienced by COPD patients. The aim of this study is to identify the impact of upper-limb endurance and strength training on dyspnoea symptom, functional capacity, quality of life and pulmonary function test results in COPD patients. Methods: We performed experimental study in June 2019 on 7 stable COPD patients according to GOLD 2019 criteria. Patients were given combined training twice a week for one month in which every session lasted 5-20 minutes gradually. Before and after training program, pulmonary function tests were measured by spirometry to obtain percent predicted of FEV1, FVC, PEFR and FEF25-75, while dyspnoea scale, functional capacity and quality of life were measured by mMRC index, 6 MWT and CAT (COPD Assessment Test). Statistical analysis was performed by Wilcoxon and paired t-test. Results: There was significant improvement of clinical symptoms after combined endurance – strength training program. Patients’ mMRC decreased from median scale 2 (range 1-3) to 1 (range 1-2) and CAT score improved from significantly from 15 (range 10-23) to 11 (range 4-12), (p = 0.04 and 0.02 respectively). There were also slight increase of all lung function parameters although not statistically significant. Baseline value of FVC (50 16.4%) increased to 57.4 18.0% (p-0.12). FEV1 and FEF25-75 also increased from 44.1 18.9% to 47.8 (P=0,12) and 34.4 24.6% to 36.2 25.9% (P=0.68) respectively. There was no significant improvement in 6 walking test before and after training (325 58.9 to 317 33.8 meters, P>0.05). There was no exacerbation found during training program. Conclusions: Twice a week combined upper-limb endurance and strength training program for one-month improved dyspnoea scale and clinical symptoms along with quality of life in COPD patients safely and effectively.
