RESUMO
This study aimed to evaluate 3D virtual reality rehabilitation therapy in patients with vertigo due to peripheral vestibular dysfunction. The subjects were 20 patients with peripheral vestibular dysfunction confirmed by Videonystagmography, Divided into 2 groups: Group 1 (study group) underwent vestibular rehabilitation therapy using 3D virtual reality in a customised VR lab with specific headset (Oculus rift and htc vive) with software application, which allows vestibular rehabilitation treatment using high quality immersive virtual reality console in which environment appears real and in 3D. The exercises are designed for gaze stability, increase postural stability, improve vertigo and daily activities, through sensory stimuli and in addition to conventional Cawthorne-Choksey exercises. Group 2 (control group) are treated by conventional Cawthorne-Choksey exercises alone. A VSS-SF (Vertigo Symptom Scale-short form) questionnaire and VAS (Visual Analog Scale) were used to assess the levels of patient satisfaction compared before and after each treatment session in both groups. A significant higher level of subjective satisfaction was observed in patients who underwent 3D virtual reality rehabilitation therapy with conventional therapy (group 1) compared to patients who underwent conventional cawthorne-Choksey exercises alone (group 2). The study gave a substantial subjective satisfaction in patients using 3D virtual reality rehabilitation therapy with conventional therapy (group1) than conventional Cawthorne-Choksey exercises alone (group 2). Future of VR rehabilitation therapy brings a revolutionary novelty in field of rehabilitation therapy were it involves real time stimulation and interaction between sensory, motor and cognitive channels.
