“…Part of these problems could be attributed to disturbed eye stabilization reflexes (Kelders et al 2005;Montfoort et al 2006). In patients with WAD and in chronic idiopathic neck pain patients the normally weak COR is found to be increased (Kelders et al 2005;Montfoort et al 2006;de Vries et al 2016;Ischebeck et al 2017). Based on the findings in this study, it can be speculated that reflex alterations are not completely dependent on the origin of complaints, but do also depend on the amount of movement.…”

“…An alternative explanation for the diversity of whiplash disorders, such as oculomotor disturbances, is tissue damage of diverse structures due to the traumatic origin of complaints (Curatolo et al 2011). However, we recently observed that eye reflex alterations are also found in nontraumatic neck pain patients Ischebeck et al 2017), making a lesion based explanation for eye reflex alterations in whiplash patients less likely. This, however, needs to be further explored.…”

To investigate the influence of the amount of cervical movement on the cervico-ocular reflex (COR) and vestibulo-ocular reflex (VOR) in healthy individuals. Eye stabilization reflexes, especially the COR, are changed in neck pain patients. In healthy humans, the strength of the VOR and the COR are inversely related. In a cross-over trial the amplitude of the COR and VOR (measured with a rotational chair with eye tracking device) and the active cervical range of motion (CROM) was measured in 20 healthy participants (mean age 24.7). The parameters were tested before and after two different interventions (hyperkinesia: 20 min of extensive active neck movement; and hypokinesia: 60 min of wearing a stiff neck collar). In an additional replication experiment the effect of prolonged (120 min) hypokinesia on the eye reflexes were tested in 11 individuals. The COR did not change after 60 min of hypokinesia, but did increase after prolonged hypokinesia (median change 0.220; IQR 0.168, p = 0.017). The VOR increased after 60 min of hypokinesia (median change 0.155, IQR 0.26, p = 0.003), but this increase was gone after 120 min of hypokinesia. Both reflexes were unaffected by cervical hyperkinesia. Diminished neck movements influences both the COR and VOR, although on a different time scale. However, increased neck movements do not affect the reflexes. These findings suggest that diminished neck movements could cause the increased COR in patients with neck complaints.

“…This naturally evolved into chiropractors viewing spine-related disorders primarily in a biomechanical and neurological context, with neurological processes being central to the development and perpetuation of these disorders. Emerging evidence largely supports this viewpoint (Seaman and Winterstein 1998;Reichling and Levine 2009;Ischebeck et al 2017;Panjabi 2003;Garcia-Larrea and Peyron 2013;Henry et al 2011;Wenngren et al 2002).…”

“…The vestibula, including three semicircular canals and otolith organs (utricle and saccule), can perceive angular velocity and the acceleration of the head (Yang et al, 2015). The VOR receives positional input from the vestibular afferents (Ischebeck et al, 2017(Ischebeck et al, , 2018 and sends signals to the eye muscles and cerebellum, which send feedback signals to modulate or fine-tune the VOR (Wallace and Lifshitz, 2016). Thus, the position of the eyes affects the movement of the head.…”

The vestibulo-ocular reflex (VOR) plays an important role in controlling the gaze at a visual target. Although patients with vestibular hypofunction aim to improve their VOR function, some retain dysfunction for a long time. Previous studies have explored the effects of direct current stimulation on vestibular function; however, the effects of random noise stimulation on eye–head coordination have not previously been tested. Therefore, we aimed to clarify the effects of high frequency noisy vestibular stimulation (HF-nVS) on eye–head coordination related to VOR function. Thirteen healthy young adult participants with no serious disease took part in our study. The current amplitude and density used were 0.4 mA and 0.2 mA/cm2, respectively, with a random noise frequency of 100–640 Hz. The electrodes were located on both mastoid processes. The stimulus duration and fade in/out duration were 600 and 10 s, respectively. Subjects oscillated their head horizontally, gazing at the fixation point, at 1 Hz (0.5 cycles/s) for 30 repetitions. The coordination of eye–head movements was measured by eye-tracking and a motion capture system. Peak-to-peak angles for eye and head movement and deviation of the visual line from the fixation target revealed no significant differences between HF-nVS and sham. The lag time between the eye and head movement with HF-nVS post-stimulation was significantly shorter than that of the sham. We found that HF-nVS can reduce the lag time between eye and head movement and improve coordination, contributing to a clear retinal image. This technique could be applied as a form of VOR training for patients with vestibular hypofunction.
