The Effect of Pulmonary Rehabilitation on the Physical Activity Level and General Clinical Status of Patients with Bronchiectasis.

Objectives: We aimed to investigate the effects of pulmonary rehabilitation (PR) on the level of physical activity (PA) and the general clinical status in adult patients with non-cystic fibrosis bronchiectasis.

Materials And Methods: The patients were included prospectively in the study and followed a home-based PR program for 2 months comprising breathing exercises, training in chest hygiene techniques, peripheral muscle strengthening training, and self-walking. The outcomes measurements were the following: 6-minute walking distance, pulmonary function test, peripheral and respiratory muscle strength measurements, International Physical Activity Questionnaire (IPAQ), Saint George Respiratory Questionnaire, and modified Medical Research Council dyspnea scores.

Results: Of the total 25 patients included in the study, six were excluded due to follow-up and adherence problems. A comparison of the outcome measures recorded before and after PR showed statistically significant improvements in the IPAQ total (p=0.015) and walking scores (p=0.011). While the proportion of patients in the low PA category was 73% (n=14) prior to PR, this rate decreased to 42% (n=8) post-PR. The proportion of patients in the moderate PA category was 26% (n=5) prior to PR and increased to 52% (n=10) post-PR. While positive improvements were seen in all clinically monitored parameters, aside from spirometric values, these changes did not reach a statistically significant level.

Conclusion: The majority of patients with bronchiectasis have a low level of PA. PR ensures positive improvements in the level of PA and general physical clinical status of such patients.
