Clinical Quantitative Assessment of Visual Motion Sensitivity in Concussion/Mild Traumatic Brain Injury

Visual motion sensitivity (VMS) is a common symptom in patients with concussion/mild traumatic brain injury (C/mTBI). It is typically assessed clinically in a qualitative manner by the patient’s case history. We propose a simple, rapid, direct, and quantitative manner for VMS assessment in this population using an OKN drum in four peripheral fields while the patient is centrally fixated.
