Differences On The Upper Quarter Y Balance Test Among Young People

Abstract

Upper Quarter Y-Balance Test is a closed kinetic chain assessment of upper quarter mobility and stability using a functional testing device. We started with the question: Are there significant differences in the bilateral upper limbs UQYBT results, recorded by the subjects engaged and not engaged in recreational physical activities? The study identifies bilateral movement limitations and asymmetries in active and not-active young people on shoulder stability and mobility as a closed kinetic chain upper extremity. The subjects are 93 young students (45 females and 48 males), 22.19 average age. They are organised in four groups: not-active and active (females and males). UQYBT is applied on all four groups of subjects. Mathematics methods as One Way ANOVA for Dependent samples and Post ANOVA Tukey HSD Test were used to identify the significant statistic differences between groups. The comparative analysis between active versus not-active groups suggests not significant statistic differences for males.For the female groups, there are not statistically significantly differences, with a few exceptions. There were statistically significantly differences, to benefit the active group, for the right upper limb (SL direction) and for the left upper limb (IL direction). The main conclusion is that UQYBT may be useful in assessing functional deficit in upper extremity stability.
