But, there are few studies to assess the relationship between the FMS test and Y Balance Test. This study aimed to assess the relationship between dynamic stability and the FMS test. Methods: The subjects of this study were 95 students (Mean±SD age=26.7±3.13 y, Mean±SD height=177.4±6.9 cm, Mean±SD weight=72.02±6.91 kg, and Mean±SD BMI=22.93±0.41 kg/ m2) from a university complex. All subjects were evaluated prior to the onset of training. Y Balance Test was used to evaluate dynamic stability and FMS test for evaluating the movement patterns of the subjects. Results: The Pearson correlation coefficient was used to assess the relationship between variables. The results showed a significant association between the FMS score and the aggregate Y score (r=0.205, P=0.04). Also, there was a weak correlation between FMS and normalized posteromedial reach (r=0.27, P=0.04). However, the correlation between FMS and normalized anterior reach and posterolateral reach was not statistically significant (P>0.05). Conclusion: These findings demonstrate partial correspondence between the two tests. However, the relationship is not strong enough to consider them interchangeable. Thus, dynamic postural control is not a large component of the aggregate FMS score.
