VSS

The Vertigo Symptom Scale (VSS) is a self-report questionnaire assessing the frequency and severity of vertigo and associated symptoms (nausea, lightheadedness, visual disturbance, head motion intolerance). Developed by Yardley et al. in 1992, the VSS measures symptom burden rather than handicap, making it distinct from disability-focused measures. The VSS is valuable for characterizing symptom clusters, monitoring symptom progression, and evaluating treatment response in vestibular and central dizziness disorders.
