| Abstract |
Sound-induced vestibular-evoked myogenic potentials (VEMPs) can be used to investigate saccular function, measured from the tonically contracted sternocleidomastoid muscles (SCM) in response to loud sound stimuli. The aim of the present study was to assess VEMPs in patients with vestibular migraine and to determine whether saccular function is affected by the disease. Furthermore, tests such as tilts of subjective visual vertical (SVV) and caloric testing were conducted to test whether deficits in the various tests are associated with each other. The amplitude and latency of VEMPs were measured from the SCM in 63 patients with vestibular migraine (median age 47 years; range 24-70 years) and compared with those of 63 sex- and age-matched healthy controls (median age 46 years; range 17-73 years). Of the 63 patients with vestibular migraine, 43 (68%) had reduced EMG-corrected VEMP amplitudes compared to the controls. Thus, the mean of the p13-n23 amplitudes of the vestibular migraine patients were 1.22 (SE +/-0.09) for the right and 1.21 (SE +/-0.09) for the left side, whereas the averaged amplitudes of the 63 healthy controls showed a mean of 1.79 (SE +/-0.09) on the right and of 1.76 (SE +/-0.09) on the left. No difference was seen in the latencies and there was no correlation between VEMP amplitudes, tilts of SVV and caloric testing. Our data on patients with vestibular migraine indicate that the VEMP amplitudes are significantly and bilaterally reduced compared to those of controls. This electrophysiological finding suggests that both peripheral vestibular structures, such as the saccule, but also central vestibular structures are affected. Thus, beside the brainstem, structures in the inner ear also seem to contribute to vertigo in vestibular migraine. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 May 2009.
All research outputs
#15,240,835
of 22,660,862 outputs
Outputs from Journal of Neurology
#3,201
of 4,445 outputs
Outputs of similar age
#78,431
of 92,947 outputs
Outputs of similar age from Journal of Neurology
#37
of 43 outputs
Altmetric has tracked 22,660,862 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,445 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.0. This one is in the 21st percentile – i.e., 21% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 92,947 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one is in the 6th percentile – i.e., 6% of its contemporaries scored the same or lower than it.
