Background： Chronic respiratory diseases and Chronic Obstructive Pulmonary Disease (COPD) are major causes of chronic illness and death worldwide. Patients with chronic respiratory diseases experience muscle weakness and respiratory difficulties, leading to restricted physical activity, decreased functional capacity, exercise intolerance, and limb muscle atrophy. While exercise training can effectively improve limb strength, there is a lack of objective data exploring different disease progressions and clinical cardiopulmonary limitations, hence this study utilizes plantar pressure distribution to research lower limb strength and cardiopulmonary function in patients, hoping to identify relevant indicators for necessary exercise training.
Methods： The study plans to enroll 60 participants, divided into two groups (30 in the control group and 30 in the case group) matched 1:1. The study will be conducted at the pulmonary rehabilitation therapy room on the sixth floor of Fu-Jen Catholic University Hospital. In addition to basic demographic and clinical physiological parameters, all participants will undergo the 6-minute walk test, the timed up and go test, simple pulmonary function tests, body composition analysis, and statistical analysis.
Effect： The trial is expected to effectively determine which patients require exercise training based on the correlation between plantar pressure analysis and results from the 6-minute walk test and timed up and go test. These results are anticipated to correlate positively with disease severity.
