Recovery of Vestibular Ocular Reflex Function and Balance Control after a Unilateral Peripheral Vestibular Deficit

Abstract: This review describes the effect of unilateral peripheral vestibular deficit (UPVD) on balance control for stance and gait tests. Because a UPVD is normally defined based on vestibular ocular reflex (VOR) tests, we compared recovery observed in balance control with patterns of recovery in VOR function. Two general types of UPVD are considered; acute vestibular neuritis (AVN) and vestibular neurectomy. The latter was subdivided into vestibular loss after cerebellar pontine angle tumor surgery during which a ves… Show more

“…The stairs task is complex as it involves the simultaneous control of posture, head and eye movements. Our results are similar to DOI: 10.1159/000494965 those described by Allum et al for patients 3 months after an acute unilateral peripheral vestibular deficit caused by vestibular neuritis [Allum and Adkin, 2003;Allum andHonegger, 2013, 2015]. Unilateral peripheral vestibular deficit patients also show abnormal sway for the stairs task 3 months after acute onset.…”

“…As might have been expected from the aforementioned description of symptoms, our major finding was that 2 years after VN pa- tients' trunk sway during tasks designed to mimic these daily activities [Allum, 2012] showed impaired balance control, particularly during stance tasks with reduced sensory inputs (eyes closed on foam) as well as during complex gait tasks such as walking up and down stairs. That is, there was no significant improvement in balance control, rather, a worsening at 2 years with respect to HCs.…”

“…Interestingly in what respects to vestibular deficit, no differences were observed (as measured with the caloric test or in the clinical head-impulse test) between patients considered to be well compensated and those noncompensated; this explains the low level difference in the amount of phase lead and gain reduction as seen in the SHA test. We must remark that patient's status (both for the vestibular deficit and vestibular compensation) was defined according to VOR function tests results: although this is an accepted method there is some criticism proceeding that way and in particular when balance recovery is to be under study [11]. A detailed analysis of the criteria shown by the patients allows us to find major differences in the frequency of spontaneous nystagmus presence and, as expected, in the amount of VOR asymmetry on the SHA test.…”
