Fig 1.
This figure shows NeuroCom reports of two participants with TBI (A. abnormal SOT performance, B. normal SOT performance). Red bars represent abnormal scores and green bars represent normal scores. Gray shading represents abnormal area that is two standard deviations from normative mean values. The individual in A, as an example, had difficulty completing the SOT test as they scored abnormal on all trials of all conditions except for trial 1 of condition 6. This individual lost balance a few times, as indicated by the word “FALL” replacing the bar on conditions 3 (trial 2), 4 (trials 2 and 3) and 5 (all trials). The individual in B had no deficits as they scored normal on every trial of every condition.
Fig 2.
This figure shows NeuroCom reports of two participants with TBI (A. abnormal LOS performance, B. normal LOS performance). The left plots show the participant’s center of gravity tracings for each trial of the LOS test. The participant is to start in the center box and lean toward each target in a clockwise manner. Ideally, the tracing should look like a star, with 8 lines radiating from the center to each target. The bar plots on the right show each participant’s scores on the forward, back, right, left directions and composite scores (all directions) for each LOS variable measured (e.g. reaction time, movement velocity, endpoint and maximal excursions and directional control). Red and yellow bars represent abnormal scores and green bars represent normal scores. Gray shading represents abnormal performance that is two standard deviations from normative mean values. The individual in A had difficulty completing the LOS test as they scored abnormal on several measures, while the individual in B had no deficits scoring normal on all measures.

These scatterplots are representative of the strength and direction of associations between balance and DTI measures. Left scatterplot: Negative correlation between LOS Reaction Time and FA of the superior longitudinal fasciculus. Right scatterplot: Positive correlation between LOS Directional Control and FA of the corpus callosum.
