Supine Roll Test (adapted from the original) procedure. The patient lies supine on an examination couch. The subject turns his head 90° to either side, while the nystagmus is recorded. The head should be maintained for 45 to 60 seconds in each position. A slight elevation of the head from the table (∼ 20°) (i.e head resting on the pillow), is recomended. 38
