Abstract
The subjects admitted for thoracic surgery have increased dyspnea levels depending on exposure in the lungs. The aim of our study was to analyze effect of respiratory muscle training on dyspnea levels of subjects undergoing thoracic surgery. Forty subjects, admitted for thoracic surgery were included into the study. The subjects were divided into two groups randomly. The subjects in group 1 (n=20) received conventional pulmonary physiotherapy the subjects in group 2(n=20) received respiratory muscle training in addition to conventional pulmonary physiotherapy. Dyspnea levels of subjects were assessed preoperative and before the discharge with Modified Medical Research Committee scale (MMRC). Dyspnea levels of subjects were analyzed as Grade 2 and lower, above of grade 2. There were no significant difference between the groups in terms of physical properties, surgery type and dyspnea levels before surgery (p>0,05). There was not any significant differencein terms of MMRC scores in conventional physiotherapy group (p>0,05) but a significant difference was found in respiratory muscle training group (p<0,05). The results of this study showed that the subjects admitted for thoracic surgery had high levels of dyspnea before surgery. When respiratory muscle training applied in addition to conventional pulmonary physiotherapy after thoracic surgery dyspnea levels decreased significantly. We think that respiratory muscle training may have positive effects on dyspnea levels of subjects undergoing thoracic surgery.
