Effect of Neuromuscular Electrical Stimulation of Lower Limbs on Improving Exercise Self-Efficacy, Dyspnea During Activity and Fatigue in Patients With Chronic Obstructive Pulmonary Disease

Обзор

Patients diagnosed with COPD who meet the inclusion and exclusion criteria, either inpatients or outpatients, will be informed about the study'sstudy's purpose and procedures by the principal investigator. After understanding their rights, they will provide informed consent.

Подробное описание

The process of the experiment The study adopts a quasi-experimental design with convenience sampling. Data collection will be done through structured questionnaires. Patients who meet the inclusion criteria will be referred by physicians, and before enrollment, a verbal introduction will be given explaining the study's purpose, the questionnaire, and the intervention procedure and duration. The experimental group will participate in both pulmonary rehabilitation exercises and an additional intervention of lower limb neuromuscular electrical stimulation, 30 minutes per session, three times per week, for eight weeks. The control group will only participate in pulmonary rehabilitation exercises. Neuromuscular electrical stimulation should continue for 4 to 8 weeks. Questionnaires will be administered before the intervention and at the 2nd, 4th, 6th, and 8th weeks post-intervention, including basic information, Modified Medical Research Council Dyspnea Scale, Manchester COPD Fatigue Scale, and Self-Efficacy for Exercise Scale. Data collection will take approximately 25 minutes, and questionnaires will be personally retrieved by the researcher.
