Vestibulo-spinal reflex tests to determine unilateral vestibular loss

Figures & data

Table 1. Comparison of Caloric and Fukuda test results in subjects with UVL.

	Caloric test
Fukuda test	Right UVL (n = 22)	Left UVL (n = 18)	Total (n = 40)
Right-Deviation	16 (40%)	6 (15%)	22 (55%)
Left-Deviation	4 (10%)	10 (25%)	14 (35%)
No deviation	2 (5%)	2 (5%)	4 (10%)
Total	22 (55%)	18 (45%)	40 (100%)

UVL: Unilateral Vestibular Loss, n: number of participants.

The bold values show the number of results and ratios where the UVL direction and the VSR tests' deviation direction are consistent.

Total	22 (55%)	18 (45%)	40 (100%)

UVL: Unilateral Vestibular Loss, n: number of participants.

The bold values show the number of results and ratios where the UVL direction and the VSR tests' deviation direction are consistent.

	Caloric test
Tandem-Walking test	Right UVL (n = 22)	Left UVL (n = 18)	Total (n = 40)
Right-Deviation	3 (7.5%)	2 (5%)	5 (12.5%)

Total	22 (55%)	18 (45%)	40 (100%)

UVL: Unilateral Vestibular Loss, n: number of participants.

The bold values show the number of results and ratios where the UVL direction and the VSR tests' deviation direction are consistent.

Both deviation	0 (0)	0 (0)	0 (0)	0 (0)
Total	30 (100)	30 (100)	30 (100)	30 (100)
