Pulmonary rehabilitation maintenance interventions: a systematic review

Area of Science:

• Pulmonary rehabilitation
• Exercise physiology
• Health maintenance

Background:

• Pulmonary exercise rehabilitation (PR) improves physical endurance.
• Sustaining PR benefits long-term remains a challenge.
• Maintenance interventions are crucial for lasting patient outcomes.

Purpose of the Study:

• To systematically review existing research on maintenance interventions for pulmonary exercise rehabilitation.
• To assess the effectiveness of current strategies in sustaining PR benefits.

Main Methods:

• Systematic review of eight studies on PR maintenance interventions.
• Primary outcome measure was physical endurance.
• Analysis focused on intervention effects and duration.

Main Results:

• Most studies showed initial improvements in physical endurance post-PR.
• These benefits significantly declined to non-significance within 3-12 months after intervention completion.
• Only one study utilized a theoretical framework for its maintenance intervention.

Conclusions:

• Current PR maintenance interventions are largely ineffective in sustaining long-term benefits.
• Future research should focus on theoretically-grounded interventions targeting known maintenance mediators.
• Longer follow-up periods and adherence measures are essential for evaluating future PR maintenance strategies.
