Multi parameter respiratory training for pulmonary rehabilitation in AECOPD a randomized controlled trial

Area of Science:

• Pulmonary rehabilitation
• Respiratory medicine
• Clinical trial methodology

Background:

• Early pulmonary rehabilitation is crucial for patients experiencing acute exacerbations of chronic obstructive pulmonary disease (AECOPD).
• Traditional rehabilitation methods often face challenges with patient adherence and monotony.
• Novel devices are needed to enhance the effectiveness of rehabilitation for AECOPD patients.

Purpose of the Study:

• To evaluate a novel multi-parameter respiratory trainer's efficacy in AECOPD patients.
• To compare the multi-parameter device against traditional methods like a three-ball trainer and pursed-lip breathing.
• To assess improvements in dyspnea, health status, exercise capacity, psychological status, and lung function.

Main Methods:

• A randomized controlled trial involving 90 AECOPD patients.
• Patients were assigned to three groups: multi-parameter device, three-ball trainer, or pursed-lip breathing, all receiving standard medication.
• Primary outcomes included dyspnea, CAT score, and six-minute walking distance; secondary outcomes were psychological status and lung function (FEV1).

Main Results:

• The multi-parameter device group showed significantly greater improvements in dyspnea, CAT scores, six-minute walking distance, and reduced depression and anxiety.
• Superior improvement in FEV1 change was observed in the multi-parameter device group compared to the pursed-lip breathing group.
• All groups demonstrated significant within-group improvements, and the multi-parameter device was found to be safe with no adverse events.

Conclusions:

• The multi-parameter respiratory training device is safe and effective for short-term, supervised inpatient pulmonary rehabilitation in AECOPD patients.
• It offers superior patient-centered outcomes compared to conventional rehabilitation methods.
• The device should be considered a complementary tool to standard respiratory training when resources permit, not a replacement.
