Effect of pursed-lip breathing and forward trunk lean positions on regional chest wall volume and ventilatory pattern in older adults: An observational study

The effect of cognition in combination with an ACBT on dyspnea-related kinesiophobia in patients with moderate to severe COPD: Quasirandomized controlled trial study

Patients with moderate to severe COPD frequently experience dyspnea, which causes these patients to acquire a fear of dyspnea and a fear of activity. This study developed a cognitive intervention combined with active cycle of breathing technique (ACBT) intervention program based on the fear-avoidance model, with the goal of evaluating the program's effectiveness in improving dyspnea-related kinesiophobia in patients with moderate to severe COPD. This study had a total of 106 participants. For 8 weeks, the intervention group (N=53) received cognitive combined with ACBT, while the control group (N=53) received standard care. The findings of the four times the dyspnea belief questionnaire were collected indicated that the combined intervention had a better impact on reducing dyspnea-related kinesiophobia than did routine nursing (P<0.05), and the impact persisted even after the intervention. Additionally, it may enhance dyspnea and quality of life, increase exercise capacity, and lower the BODE index.
