Using weight training with virtual reality can help after discharge patients of acute exacerbation of chronic obstructive pulmonary disease, which maintained their quality of life, and improved their exercise capacity, pulmonary function, readmission condition.

Chronic obstructive pulmonary disease (COPD) is a type obstructive lung disease which had become the third leading cause of deaths worldwide. The main symptoms including dyspnea, coughing, sputum production and acute exacerbation of COPD (AECOPD). The physical activity level, muscle power, exercise tolerance and quality of life (QoL) would decline rapidly when an episode of AECOPD occurred, with the worsen of the pulmonary function and activities level, the patient would get weaker and mortality rate would increase. Pulmonary rehabilitation (PR) had become a common-used clinical programs which including (but not limit to) medication, education, psychological support, nutrition consultation and exercise interventions.

In PR programs, exercise had been specifically pointed out for its improvement of physical activity level and quality of life, however, the adherence rate of programs remains low due to lack of motivation and insufficient training effect. Previous interventions preferred aerobic exercise conducting in sitting position considering the long-term sedentary life style of patients. However, such an intervention demonstrated little effect on increasing muscle power of lower extremities, results in insufficient physical activity level and functional performance. Besides, the interventions are usually single and repeatedly limb movement exercise which fail to brings up interests and results in poor motivation of the patients. Literatures review has suggested the highly involvement of upper extremities which is strongly contributed to independently daily living. The implantation of virtual reality in PR program has gained attentions with its advantage of facilitate the motivation. Therefore, the study aims to conduct the muscle strength training including both upper and lower extremities with the combination of virtual reality (VR). Anticipated result expects to provide a research evidence of innovative pulmonary rehabilitation exercise intervention.

The study will recruited 30 participants who will be randomly divided into control and intervention group. Control group will receive routine pulmonary rehabilitation including medication and education, the research stuff will give a brief explanation of home exercise, and weekly telemedicine to follow the exercise intensity and provide conciliation. Intervention group will receive the routine medical care. Extra weight training program targeting on upper extremities with the VR headsets will be conducted with the accompany of the research stuff. 3 times a week for 8 weeks (as a 24-times interference totally) interventions with muscle strength, exercise capacity, pulmonary function and improvement of quality of life will be assess to investigate the training effects. Expected result including the progression of muscle strength, oxygen uptake level, as well as pulmonary performance. The implantation of VR will also improve the motivation to participant, which will further alleviate the symptoms and quality of life. It can also provide some research evidence for clinical therapist to conduct an individualized exercise prescription for COPD.
