Reduced Gain and Shortened Time Constant of Vestibular Velocity Storage as a Source of Balance and Movement Sensitivities in Gravitational Insecurity

Figure 1

Population, study, and clinic sample PGrI scores plotted on a modified log scale. Back row population sample (black, ): 70% have scores ≤3 and 9% have scores ≥7. Upper right inset: linear -axis number scale shows true left skew of population scores. Front row clinic sample: OT clinic individuals without GrI (white) and OT clinic individuals with GrI (gray). Middle row: study comparison group (vertical stripes) is from 70% of population without balance problems. Balance-challenged MGrI scores (horizontal stripes) are within range of OT clients with GrI.
