A search for controlled trials of physical training in bronchiectasis only identified one full text publication which contains data from the 2 earlier abstracts, including 43 patients in total. These suggest some benefits of inspiratory muscle training on exercise capacity, quality of life and respiratory muscle function at eight weeks, but further research is needed to confirm these findings in larger numbers of people with bronchiectasis. Further research is also needed to assess the benefit of other types of physical training and pulmonary rehabilitation in bronchiectasis.

---
The pathophysiology of bronchiectasis may result in the development of dyspnoea and decreased exercise tolerance, both of which can impact on a patient's quality of life and ability to perform activities of daily living. There is little information regarding the benefits of physical training in bronchiectasis: however it is probable that the benefits of physical training in bronchiectasis are at least comparable to benefits demonstrated in other respiratory conditions. There is also no information regarding the effects of non-adherence to prescribed physical training in bronchiectasis. However as in patients with COPD non-adherence may contribute to a deterioration in the patient's condition and conceivably the long term prognosis.
Cele
The objective of this review is to determine whether a prescribed regime of physical training produces improvements or prevents deterioration in physiological and clinical outcomes in bronchiectasis compared to no physical training.
Metody wyszukiwania badań
We searched the Cochrane Airways Group trials register and the Cochrane Central Register of Controlled Trials. Searches are current to February 2009.
Kryteria doboru badań
Randomised or quasi randomised controlled trials in which a prescribed regimen of physical training is compared to no physical training in patients with bronchiectasis.
Zbieranie i analiza danych
One study (data reported in full text publication), and two abstracts met the inclusion criteria for this review.
Główne wyniki
Results from the full text publication showed that pulmonary rehabilitation (PR), with or without inspiratory muscle training (PR-IMT or PR-SHAM) resulted in significant increases in the incremental shuttle walking test of 96.7m (95% CI 59.6-133.7) and 124.5m (95% CI 63.2-185.9) respectively, and in endurance exercise capacity of 174.9% (95% CI 34.7- 426.1) and 205.7% (95% CI 31.6-310.6) respectively. There were no statistically significant differences in the improvements in exercise between the two groups. Significant improvements in inspiratory muscle strength were also observed both in the PR-IMT group (21.4 cmH2O increase, 95% CI 9.3- 33.4, p=0.008) and the PR-SHAM group (12.0 cmH2O increase, 95% CI 1.1- 22.9, p=0.04).
Wnioski autorów
This review only provides evidence of the benefits of inspiratory muscle training and provides no evidence of the effect of other types of physical training (including pulmonary rehabilitation) in bronchiectasis.
