Tekscan offers computerized BESS test

Boston-based Tekscan’s late-2013 release of the MobileMat BESS paired its pressure-sensing platform with software for quantifying balance errors during the standard or modified Balance Error Scoring System (BESS) test, which is widely used in sports concussion assessment.

Although researchers generally accept the BESS test’s validity, some have raised concerns about inter-rater and intrarater reliability of manual scoring.

Tekscan submitted its system for testing to Thomas Kaminski, PhD, ATC, professor of kinesiology and applied physiology at the University of Delaware in Newark, and colleagues, who tested the product’s scoring accuracy. The researchers compared MobileMat BESS system results from about 100 athletes with results for the same group tested with standard protocols and found the MobileMat BESS scored balance errors as well as three trained testers (unpublished data).
