How do you measure upper extremity dynamic stability? The recently described UQ-YBT offers a reliable way to objectively measure upper trunk stability and mobility in a closed kinetic chain position. The UQ-YBT allows us to measure limb symmetry and identify potential limitations that could contribute to an individuals injury risk. Limb Symmetry Index: The LSI provides a ratio comparing the performance between 2 lower extremities of the same individual; this is clinically useful in determining lower extremity asymmetry.J Orthop Sports Phys Ther 2001;3 1:145-151.
