Table 2.

Orientation angle and tilt angle (both in degrees) for a subset of animals tested under both pre-current and current conditions

Group	Pre-current		Current
	Orientation angle	Tilt angle	Orientation angle	Tilt angle	n
Untreated	109	48.6	2	18.8	16
Cobalt	121	44.2	34	36.5	14
Streptomycin	87	39.3	29	27.1	14
Gentamicin	107	33.8	16	10.9	15

There is no statistical difference in orientation angle and tilt angle between the four groups in the pre-current condition. The introduction of current significantly influenced orientation for all groups, and decreased tilt angle for the untreated and gentamicin-treated groups
