Benign paroxysmal positional vertigo — DVA SoP factors

Reasonable Hypothesis (RH) — Statement of Principles No. 56 of 2017

At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting benign paroxysmal positional vertigo or death from benign paroxysmal positional vertigo with the circumstances of a person's relevant service:

1. (1)
   having trauma involving the head or the head and neck within the 30 days before the clinical onset of benign paroxysmal positional vertigo;

   Note: Types of trauma include the head being struck by an object, the head striking an object or the head undergoing jolting movements.

2. (2)
   having surgery to the head or neck, including dental surgery, where that surgery involves transmission of vibration or percussive forces to the inner ear, in the three months before the clinical onset of benign paroxysmal positional vertigo;
3. (3)
   having cochlear implantation surgery in the three years before the clinical onset of benign paroxysmal positional vertigo;
4. (4)
   having Meniere's disease on the affected side before the clinical onset of benign paroxysmal positional vertigo;
5. (5)
   having vestibular neuritis or labyrinthitis on the affected side within the three months before the clinical onset of benign paroxysmal positional vertigo;
6. (6)
   being infected with herpes simplex virus or varicella zoster virus, where there is evidence of the infection causing a clinical illness involving the vestibular nerve of the affected side, before the clinical onset of benign paroxysmal positional vertigo;
7. (7)
   undertaking physical activity at a rate of at least six METs, where the activity involves sudden head turning, jolting or vibration of the body, within the seven days before the clinical onset of benign paroxysmal positional vertigo;

   Note: MET is defined in the Schedule 1 - Dictionary.

8. (8)
   having active migraine at the time of the clinical onset of benign paroxysmal positional vertigo;

   Note: active migraine is defined in the Schedule 1 - Dictionary.

9. (9)
   being in the Trendelenburg position for a surgical procedure within the seven days before the clinical onset of benign paroxysmal positional vertigo;

   Note: Trendelenburg position is defined in the Schedule 1 - Dictionary.

10. (10)
    being confined to bed for medical or surgical treatment for periods of at least three days within the 14 days before the clinical onset of benign paroxysmal positional vertigo;
11. (11)
    having decompression sickness at the time of the clinical onset of benign paroxysmal positional vertigo;
12. (12)
    having trauma involving the head or the head and neck within the 30 days before the clinical worsening of benign paroxysmal positional vertigo;

    Note: Types of trauma include the head being struck by an object, the head striking an object or the head undergoing jolting movements.

13. (13)
    having surgery to the head or neck, including dental surgery, where that surgery involves transmission of vibration or percussive forces to the inner ear, in the three months before the clinical worsening of benign paroxysmal positional vertigo;
14. (14)
    having cochlear implantation surgery in the three years before the clinical worsening of benign paroxysmal positional vertigo;
15. (15)
    having Meniere's disease on the affected side before the clinical worsening of benign paroxysmal positional vertigo;
16. (16)
    having vestibular neuritis or labyrinthitis on the affected side within the three months before the clinical worsening of benign paroxysmal positional vertigo;
17. (17)
    being infected with herpes simplex virus or varicella zoster virus, where there is evidence of the infection causing a clinical illness involving the vestibular nerve of the affected side, before the clinical worsening of benign paroxysmal positional vertigo;
18. (18)
    undertaking physical activity at a rate of at least six METs, where the activity involves sudden head turning, jolting or vibration of the body, within the seven days before the clinical worsening of benign paroxysmal positional vertigo;

    Note: MET is defined in the Schedule 1 - Dictionary.

19. (19)
    having active migraine at the time of the clinical worsening of benign paroxysmal positional vertigo;

    Note: active migraine is defined in the Schedule 1 - Dictionary.

20. (20)
    being in the Trendelenburg position for a surgical procedure within the seven days before the clinical worsening of benign paroxysmal positional vertigo;

    Note: Trendelenburg position is defined in the Schedule 1 - Dictionary.

21. (21)
    being confined to bed for medical or surgical treatment for periods of at least three days within the 14 days before the clinical worsening of benign paroxysmal positional vertigo;
22. (22)
    inability to obtain appropriate clinical management for benign paroxysmal positional vertigo;

Aggravation-only factors: the factors in subsections 8(12) to 8(22) apply only to material contribution to, or aggravation of, the condition where it was suffered or contracted before or during (but did not arise out of) the person’s relevant service.
