Fatigue has been shown to adversely affect balance results, as measured by the Balance Error Scoring System (BESS). The present study aimed to determine whether a new low-cost force plate for concussion balance assessment, the Balance Tracking System (BTrackS), is subject to similar fatigue effects. Significant fatigue effects were only evident immediately following a fatigue protocol (p > .05), and were fully resolved within 5 min postfatigue. These results suggest that the BTrackS Balance Test (BBT) is more fatigue resistant than the BESS, and support use of the BBT as a potentially more reliable alternative to the BESS during immediate sideline balance testing.
