Abstract

To investigate the effectiveness of paced breathing guided by biofeedback on clinical and functional outcomes of patients with chronic obstructive pulmonary disease (COPD). An uncontrolled pilot study comprising a training with paced breathing guided by biofeedback (three sessions of 35 min per week) was conducted over four weeks (12 sessions). Assessments included respiratory muscle strength (using a manovacuometer), anxiety (Beck Anxiety Inventory), depression (Beck Depression Inventory), dyspnea (Baseline Dyspnea Index), functionality (Timed Up and Go Test), health status (COPD Assessment Test) and health-related quality of life (Saint George’s Respiratory Questionnaire). The sample consisted of nine patients with a mean age of 68.2 ± 7.8 years. After intervention, patients significantly improved in health status and health-related quality of life, assessed using the COPD Assessment Test (p < 0.001) and Saint George's Respiratory Questionnaire (p < 0.001); anxiety (p < 0.001); and depression (p = 0.001). Patients also significantly improved in dyspnea (p = 0.008), TUG (p = 0.015), CC Score (p = 0.031), and maximum inspiratory (p = 0.004) and expiratory pressures (p < 0.001). An intervention with paced breathing guided by biofeedback promoted positive results on dyspnea, anxiety, depression, health status and perceived health-related quality of life in patients with COPD. Moreover, gains in respiratory muscle strength and functional performance were observed, affecting the performance of daily activities.

生物反馈引导下有节奏呼吸对慢性阻塞性肺病患者临床和功能结果的有效性：一项非对照的初步研究。

研究生物反馈引导的有节奏呼吸对慢性阻塞性肺病（COPD）患者临床和功能结果的有效性。一项不受控制的试点研究在四周（12次）内进行，包括在生物反馈指导下进行的有节奏呼吸训练（每周3次，每次35分钟）。评估包括呼吸肌肉力量（使用压力计）、焦虑（Beck焦虑量表）、抑郁（Beck抑郁量表），呼吸困难（基线呼吸困难指数）、功能（Timed Up and Go Test）、健康状况（COPD评估测试）和健康相关生活质量（圣乔治呼吸问卷）。样本由9名患者组成，平均年龄68.2岁 ± 7.8年。干预后，患者的健康状况和健康相关的生活质量显著改善，使用COPD评估测试进行评估（p

期刊介绍： Applied Psychophysiology and Biofeedback is an international, interdisciplinary journal devoted to study of the interrelationship of physiological systems, cognition, social and environmental parameters, and health. Priority is given to original research, basic and applied, which contributes to the theory, practice, and evaluation of applied psychophysiology and biofeedback. Submissions are also welcomed for consideration in several additional sections that appear in the journal. They consist of conceptual and theoretical articles; evaluative reviews; the Clinical Forum, which includes separate categories for innovative case studies, clinical replication series, extended treatment protocols, and clinical notes and observations; the Discussion Forum, which includes a series of papers centered around a topic of importance to the field; Innovations in Instrumentation; Letters to the Editor, commenting on issues raised in articles previously published in the journal; and select book reviews. Applied Psychophysiology and Biofeedback is the official publication of the Association for Applied Psychophysiology and Biofeedback.
