Study Arms:
- Virtual Reality (Type: EXPERIMENTAL): Progressive immersive training with the virtual reality app Scenes: start from most salient to the patient, eventually do all Duration: start at 60 seconds, increase over time up to 3 minutes per scene Complexity: start minimal, gradually increase up to most complex Tasks: standing with diverse base of support (BOS), head turns (progress with speed, planes); stepping, turning 8 weeks, 1 visit per week, 30 minutes long In home: Gait and balance exercises, No exercises with eyes closed, 8 weeks, 6 times per week, twice per day, 10 minutes long
- Traditional Vestibular Rehabilitation (Type: ACTIVE_COMPARATOR): Progressive gait, gaze stability and balance exercises Gait: walking with head turns, progress with range, speed and planes of head movement; change of walking BOS: wide, normal, tandem Gaze: focus on a target while moving head side to side / up down. Progress with speed, duration, busier background, standing to walking.~Balance: standing balance tasks, progress with BOS (wide to narrow to tandem), support surface, eyes closed, duration, head turns.~8 weeks, 1 visit per week, 30 minutes long In home: Gait, gaze stability and balance exercises, including exercises with eyes closed, 8 weeks, 6 times per week, twice per day, 10 minutes long

Based on this trial design, predict the completion outcome and termination type (if applicable).
