Cervical test
Registration of the ocular movements provoked by passive trunk to stationary held head rotation
based on the cervico-ocular reflex (COR)
may be candidate for non-invasive, quantitave assessment of the neck proprioceptive influx
principle - neck torsion without head in space movement, i.e. without vestibular stimulation
many paradigms used differ in the velocity profiles, frequencies used, may include static torsion or dynamic movements
clinical variant known as De Kleyn test, is designed particularly for diagnosis of vertebral arteries involvement
