Micro-compensatory-saccadic eye movements in people living with moderate multiple sclerosis. Head and eye velocity traces are shown in (A) and head and eye position traces are shown in (B) for a representative vHIT result for a person living with moderate multiple sclerosis. The double arrow highlights possible micro-compensatory-saccadic eye movements that were of too low acceleration and velocity to be adequately detected and parsed by our custom software, despite halving the detection thresholds (A), that correspond with a slow return of the eye-in-space position to 0 degrees (B). °/s = degrees/s. deg. = degrees. ms = milliseconds.
