Balance Error Scoring System

A simple vision test performed on the sports sidelines was able to identify nearly 8 out of 10 athletes later found to have suffered a concussion, and when test results were combined with tests for cognition and balance, allowed identification of concussed athletes with 100% accuracy, according to researchers at New York University.

One of the signs usually but not always present with concussion is poor balance. An athlete's balance and equilibrium can be tested using low-technology, intermediate technology, and high-technology methods, but the most widely used and validated is the Balance Error Scoring System (BESS).
