The aim of this study is to evaluate the effect of expiratory muscle training (EMT) on respiratory functions, respiratory muscle strength and cough strength in patients with bronchiectasis.

A total of 14 (6 women; 8 men) patients completed the study in the education group and 15 (7 women; 8 men) patients in the sham EMT group. Patients' respiratory muscle strength [maximum expiratory pressure (MEP) and maximum inspiratory pressure (MIP)] and cough strength were determined.Pulmonary function testing was performed. The training group and the sham EMT group were treated for three days in an 8-week week. In addition to the pulmonary rehabilitation, resistant EMT was given in the training group, the while EMT was given without loading the sham EMT group.

When the results of the two groups were compared before the treatment, there was no significant difference between the Respiratory function test (FEV1,FVC, FEV1/FVC and PEF),MIP, MEP and cough strength (p>0.05).When the two groups were compared after the treatment, a significant difference was observed between the MIP, MEP and cough strength in favor of the training group (p<0.05). There was no difference inFEV1,FVC, FEV1/FVC and PEF after the treatment (p>0.05). When the pre-and post-treatment results were compared, there was a significant difference in the education group in the MIP, MEP,andcough strength (p<0.05), while a significant difference was not found in the Sham EMT group (p>0.05).

As a result, the expiratory respiratory muscle training program increases respiratory muscle strength andcough strength in bronchiectasis patients. These results will guide the pulmonary rehabilitation of patients with bronchiectasis.
