Abstract Summary
The Upper Quarter Y Balance Test (YBT-UQ) is a closed-chain upper extremity (UE) test that allows clinicians to assess unilateral UE function in the reaching and the stabilizing limb. There are several aspects of the YBT-UQ that have been studied (reliability, validity, correlations to other functional tests). However, sex specific and side dominance differences regarding muscle activation have not been studied. Sex and side differences in muscle activation patterns among select UE muscles will be described.
