Home-based, upper-arm exercise training for patients with chronic obstructive pulmonary disease

Area of Science:

• Pulmonary Rehabilitation
• Exercise Physiology
• Chronic Obstructive Pulmonary Disease (COPD) Management

Background:

• Upper extremity training enhances arm strength and endurance in pulmonary rehabilitation.
• Severe COPD patients often face mobility issues hindering access to traditional rehabilitation centers.
• Home-based exercise programs are needed to overcome access barriers for COPD patients.

Purpose of the Study:

• To evaluate the efficacy of a home-based upper-arm exercise program for severe COPD patients.
• To assess improvements in arm strength, endurance, and daily living activity-related breathlessness and fatigue.
• To determine if home-based training can reduce perceived fatigue and breathlessness.

Main Methods:

• Pilot study with 20 severe COPD patients (FEV1 0.80 +/- 0.42) randomized into experimental and control groups.
• Experimental group performed 3 upper-arm exercises 5x/week for 8 weeks with progressive overload during home visits.
• Control group received equivalent attention via weekly contact.

Main Results:

• No significant differences in upper-extremity endurance (rings moved) between groups.
• Significant interaction for perceived fatigue (p = 0.0012), with the experimental group reporting less fatigue during arm work.
• No significant changes in perceived breathlessness were observed.

Conclusions:

• A home-based upper-arm exercise program can decrease perceived fatigue in severe COPD patients during arm-intensive activities.
• Further research with larger samples is warranted to confirm benefits for unsupported arm work capacity.
• Home-based pulmonary rehabilitation offers a viable alternative for COPD patients with mobility limitations.
