OBJECTIVE: To determine whether alterations to the Balance Error Scoring System
(BESS), such as modified conditions and/or instrumentation, would improve the
ability to correctly classify traumatic brain injury (TBI) status in patients
with mild TBI with persistent self-reported balance complaints. DESIGN: Cross-sectional study. SETTING: Outpatient clinic. PARTICIPANTS: Subjects (n=13;
age, 16.3+/-2y) with a recent history of concussion (mild TBI group) and
demographically matched control subjects (n=13; age, 16.7+/-2y; control group).
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Outcome measures included
the BESS, modified BESS, instrumented BESS, and instrumented modified BESS. All
subjects were tested on the noninstrumented BESS and modified BESS and were
scored by visual observation of instability in 6 and 3 stance conditions,
respectively. Instrumentation of these 2 tests used 1 inertial sensor with an
accelerometer and gyroscope to quantify bidirectional body sway. RESULTS: Scores
from the BESS and the modified BESS tests were similar between groups. However,
results from the instrumented measures using the inertial sensor were
significantly different between groups. The instrumented modified BESS had
superior diagnostic classification and the largest area under the curve when
compared with the other balance measures. CONCLUSIONS: A concussion may disrupt
the sensory processing required for optimal postural control, which was measured
by sway during quiet stance. These results suggest that the use of portable
inertial sensors may be useful in the move toward more objective and sensitive
measures of balance control postconcussion, but more work is needed to increase
sensitivity.
