OBJECTIVE: To compare equilibrium scores between computerized dynamic posturography tests of the Sensory Organization Test (SOT) to the Head Shake-Sensory Organization Test (HS-SOT) in healthy adults. BACKGROUND: Approximately 50% of the brain's pathways are related to vision and many of these pathways are susceptible to injury in concussion. Visual-motor disruptions occur in 65%-90% of concussed patients. These disruptions impair balance and can be measured. The SOT is a computerized postural test that evaluates balance by altering visual, proprioceptive, and vestibular cues. The HS-SOT modifies 2 of the standard SOT conditions by including dynamic head motions that stimulate the semicircular canals within the vestibular system. DESIGN/METHODS: Participants completed the Dizziness Handicap Inventory, Activities of Balance Confidence Scale, SOT, and HS-SOT in one session. RESULTS: Twenty-five individuals (17 females, 8 males; mean age, 21.08 ± 4.10 years, range, 18-33 years) completed outcome measures and 3 trials of testing. There was a significant difference in mean values between the SOT and the HS-SOT for both condition 2 (t(16) = 3.034, p = 0.008) and 5 (t(16) = 5.706, p < 0.001). Additionally, there was a significant difference in mean values between the SOT and the foam HS-SOT for condition 2 (t(16) = 4.673, p < 0.001) and condition 5 (t(16) = 7.263, p < 0.001). There was not a significant difference in means between the foam and without foam for HS-SOT for condition 2 (t(16) = 1.77, p = 0.095) and condition 5 (t(16) = 1.825, p = 0.087). CONCLUSIONS: The HS-SOT may quantify subtle balance deficits and enhance the clinical standard use of the SOT. Unlike the SOT where the head is static, the HS-SOT requires head movements, as if saying no repeatedly at approximately 100°/second as measured by an accelerometer. The HS-SOT may quantify subtle balance deficits and enhance the clinical standard use of the SOT.
