Note that bootstrapping results were primarily used to determine the utility of a shorter battery. They are therefore based on data from participants who completed all aspects of the neurosensory exam (i.e., no missing data). Abbreviations— KD-T/KD-E: King-Devick Test (Completion time/Errors); MAC-L/MAC-R: Monocular Accommodative Amplitude (Left Eye/Right Eye); NPC: Near point of convergence; SAH/SAV: Saccades (Horizontal/Vertical); SMP: Smooth pursuit; TGF-E/TGB-E: Tandem gait errors (Forward/Backward); VMS: Visual motion sensitivity; VOV: Vestibular-ocular reflex (Vertical).
