Materials and Methods: Thirty female students aged between 18 to 30 years with RSP participated in this study. First, the examiner measured the RSP (in supine position), Pectoralis Minor Length (PML) and Total Scapular Distance (TSD). Then, the subjects performed 5 sets of 1-min WBV (frequency=30 Hz, amplitude=5 mm) with 1 min rest between each set. After intervention, the examiner immediately measured the above mentioned variables. The paired t test was used for data analysis. Results: The analysis showed that WBV significantly decreased the supine measurement of RSP (P<0.001) and TSD (P=0.03) and increased PML (P <0.001). Conclusion: It seems that WBV had immediate effect on postural correction of rounded shoulder posture in the study subjects.   https://jmr.tums.ac.ir/index.php/jmr/article/view/80 https://jmr.tums.ac.ir/index.php/jmr/article/download/80/71
