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

Abstract

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. 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. 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. 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.
