[Home-based versus ambulatory hospital-based training in COPD]

Area of Science:

• Pulmonary Rehabilitation
• Exercise Physiology
• Chronic Disease Management

Background:

• Limited data exists on the efficacy of home-based training (rD) for patients with chronic obstructive pulmonary disease (COPD).
• Understanding the effectiveness of rD compared to traditional hospital-based rehabilitation (rH) is crucial for expanding patient access and adherence.

Purpose of the Study:

• To compare the effects of home-based training (rD) versus hospital-based training (rH) on exercise tolerance, dyspnea, and quality of life in COPD patients.

Main Methods:

• Two groups of 25 COPD patients underwent 8 weeks of either rD or rH.
• Assessments included spirometry, dyspnea and quality of life questionnaires, and submaximal/maximal exercise tests.
• Training protocols involved aerobic and strength exercises tailored to each group's setting.

Main Results:

• Both rD and rH significantly improved endurance time limit (Tlim), with no significant difference between groups.
• Improvements in shuttle resistance distance and 6-minute walk test distance were observed in both groups.
• The rH group showed a significant reduction in St. George's scoring for quality of life, which was not observed in the rD group.
• Dropout rates were higher in the rD group (32%) compared to the rH group (20%).

Conclusions:

• Home-based training (rD) is as effective as hospital-based training (rH) in improving exercise tolerance for COPD patients.
• Despite comparable effectiveness, adherence remains a challenge for home-based programs, necessitating strategies to reduce dropout rates.
