Demographics and clinical tests results of subjects in the virtual reality-based therapy group (VRBT) and the customized physical therapy group (PT) at baseline concerning age, gender, duration of symptoms, and laboratory tests [oculomotor testing, positional testing, caloric testing, rotational chair testing, and vestibular-evoked myogenic potentials (VEMPs)].
