| Abstract |
The medial vestibulospinal tract (VST) is known to mediate the vestibular-evoked myogenic potential (VEMP) in the contracting sternocleidomastoid muscle (SCM). To determine whether disruption of the medial VST in the medulla impairs formation of VEMP, we measured VEMP in 14 patients with medial medullary infarction (MMI). VEMP was induced by a short tone burst and was recorded in contracting SCM while patients turned their heads forcefully to the contralateral side against resistance. Normative data were obtained from 47 healthy volunteers. Seven patients (50%) had abnormal VEMP in the side of the MMI lesion, absent in two, decreased in four, and delayed in two. One patient showed both decreased and delayed response. Of the seven patients with abnormal VEMP, five had the lesions that extended to the dorsal tegmentum while five of the seven patients with normal VEMP showed restricted anteromedial lesions mainly involving the pyramids. Spontaneous nystagmus (4/7, 57%), gaze-evoked nystagmus (6/7, 86%), and ocular tilt reaction/tilt of the subjective visual vertical (4/7, 57%) were frequently observed in the patients with abnormal VEMP. The abnormal VEMP in patients with infarctions involving the medullary tegmentum supports that VEMP is mediated by the medial VST descending within the medial longitudinal fasciculus. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. 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 26 March 2023.
All research outputs
#7,720,531
of 23,477,147 outputs
Outputs from Journal of Neurology
#1,866
of 4,585 outputs
Outputs of similar age
#49,665
of 167,286 outputs
Outputs of similar age from Journal of Neurology
#8
of 18 outputs
Altmetric has tracked 23,477,147 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,585 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.2. This one is in the 40th percentile – i.e., 40% 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 167,286 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
