This single-case study aims to evaluate the clinical effects of optokinetic stimulation (OKS) on dizziness perception and quality of life in a patient diagnosed with Mal de Débarquement Syndrome (MdDS). The intervention follows a standardized protocol in which the patient performs head roll movements synchronized with optokinetic visual stimulation at a frequency of 0.167 Hz (10 bpm). The study is conducted online using a digital application to provide full-field optokinetic stimulation. The patient's baseline motion sickness susceptibility was characterized using the Motion Sickness Susceptibility Questionnaire-Short Form (MSSQ-SF). Primary outcome measures assessed for change from baseline include the Dizziness Handicap Inventory (DHI), Visual Analog Scale (VAS), and the Istanbul MdDS Scale
