title: Reference values for the Y Balance Test and the lower extremity functional scale in young healthy adults.
abstract: [Purpose] This study aimed to establish gender-specific reference values for the Y Balance Test (YBT) and the Arabic version of the Lower Extremity Functional Scale (LEFS-Ar) in healthy young adults in Saudi Arabia, and to examine gender differences in the YBT and LEFS-Ar values. [Subjects and Methods] Healthy young adults (31 females, 30 males) completed the YBT and LEFS-Ar in 1 test session. Descriptive statistical analysis (mean, standard deviation, 95% confidence interval) was used to compute the YBT and LEFS-Ar reference values. Independent t-tests were used to examine gender differences in the YBT and LEFS-Ar values. [Results] Gender-specific reference values were obtained for the right, left, dominant, and non-dominant leg as well as for the average performance of both the legs. males showed greater YBT normalized reach distances than females did in the anterior, posteromedial, and posterolateral directions; furthermore, males showed higher YBT composite scores than females did. However, the LEFS-Ar values did not differ between males and females. [Conclusion] Gender-specific reference values were obtained for the YBT and LEFS-Ar in healthy young adults in Saudi Arabia. males performed better than females did in the YBT. However, no gender differences were noted in LEFS-Ar.
