The effect of forward shoulder correction on pulmonary function of elementary female students

Human body posture influences on his/her physiological functions. The purpose of this study was to investigate the effect of forward shoulder correction on pulmonary function of elementary female students. Subjects of this quasi-experimental research were two groups (n=20) of students with Normal posture (NP) and forward shoulder posture (FSP) which is divided randomly into two control (n=10) and experimental (n=10) groups. Experimental work included stretch-strength training for 6 weeks. The amount of shoulder deviation and slow vital capacity (SVC) and forced vital capacity (FVC) were evaluated at pretest and post test by Double Square device and spirometre respectively. the results of paired t-test indicated a significant reduction of shoulder deviation and significant increase of SVC and FVC due to experimental work in the FSP group (P≤0. 05) but in the NP group no significant changes were observed. based on these findings، corrective exercises causes FVC and SVC improvement through correction of elementary female students’ forward shoulder posture.
