Kinematic and Kinetic Predictors of Y-Balance Test Performance

# Background The Y-Balance Test (YBT) assesses dynamic stability and neuromuscular control of the lower extremity. Several authors have analyzed kinematic predictors of YBT performance with conflicting results, but the influence of kinetic factors is not well understood. # Purpose To examine kine...
