Motion Sensitivity Quotient/Test (MSQ/MST)

The Motion Sensitivity Test finds out which movements make a person dizzy, and how badly. Rather than asking someone to describe their dizziness, the therapist takes them through sixteen quick changes of head and body position — sitting to lying down, rolling over, turning the head while seated, bending forward — and records what each one provokes.

For every position, two things are noted: how long the dizziness lasts, scored 1 to 3, and how intense it felt, rated 0 to 5 by the person. Those combine into a raw score out of 8 per position, 128 in total. A formula then converts the raw total into a quotient from 0 to 100, weighting the number of provoking positions most heavily.
