This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Background: To verify the efficacy of caloric vestibular stimulation in patients with peripheral vestibular dysfunction after cerebral hypertensive crisis. Methods: Enrolled in the study were 60 patients with peripheral vestibular dysfunction caused by a cerebral hypertensive crisis, docu- mented by vestibulometry. Thirty patients underwent standard treatment plus caloric vestibular stimulation, and 30 control group patients received standard treatment alone. Results: After the two-week treatment course, the sensation of vertigo was observed in 40.0% ± 8.9% of treatment group patients compared with 80.0% ± 7.3% of control group patients (t = 3.46; p < 0.001). Spon- taneous vestibular somatic reactions were found in 46.7% ± 9.1% of the study treatment group in contrast to 86.7% ± 6.2% of the control group (t = 3.63; p < 0.001). Spontaneous nystagmus was seen in 40.0% ± 8.9% of treatment group patients compared with 93.3% ± 4.6% of control sub- jects (t = 5.31; p < 0.001). -

Abstract The general public and workers can be exposed to high-levels of power-line frequency magnetic fields (MFs - up to 10 mT). Although such time-varying MFs have the potential to modulate human postural control, no existing studies have explored MF exposure levels that possibly trigger acute sway responses. This work evaluates time-varying MF exposure (up to 100 mT) in the extremely low frequency range (ELF – up to 300 Hz) and its effects on human postural control. Twenty-two healthy participants were each exposed to randomized, 5-second MF and electric stimulations (0, 50 and 100 mT and 1.5 mA respectively) given at different frequencies (20, 60, 90, 120, and 160 Hz). -

Teasdall, MD* Multiple stretch reflexes occur in muscles adjacent to or remote from the tap. The response may be ipsilateral or bilateral. These reflexes are encountered not only in normal subjects with brisk stretch reflexes but particularly in patients with lesions of the upper motor neuron. The concussion obtained by the blow is conducted along bone to muscle. Muscle spindles are stimulated, and in this manner independent stretch reflexes are produced in these muscles. This mechanism is responsible for the phenomenon of multiple stretch reflexes. The thorax and pelvis play important roles in the contralateral responses by transmitting these mechanical events across the midline. (Henry FordHosp Med J 1986;34:31-6) ontraction of muscles remote from the site of f)ercussion is Head and neck Cencountered in patients with brisk stretch reflexes. -

Original Article Brainstem Injury Associated with Supratentorial Lesions Is Revealed by Electronystagmography of the Cold Caloric Reflex Test
Am J Transl Res 2017;9(5):2119-2131 www.ajtr.org /ISSN:1943-8141/AJTR0046971 Original Article Brainstem injury associated with supratentorial lesions is revealed by electronystagmography of the cold caloric reflex test Qizhi Fu1, Zhiguo Qi2, Ruirui Yang3, Ke Cheng4, Yongtao Yang4, Peng Xie5 1Department of Neurology, The First Affiliated Hospital and College of Clinical Medicine of Henan University of Science and Technology, Luoyang, China; 2Department of Neurology, The First Affiliated Hospital of JiamusiU ni- versity, Jiamusi, China; 3Department of Neurology, The Shandong Provincial Hospital, Jinan, China; 4Institute of Neuroscience, Chongqing Medical University, Chongqing, China; 5Department of Neurology, The First Affiliated Hospital of Chongqing Medical University, Chongqing, China Received December 20, 2016; Accepted March 22, 2017; Epub May 15, 2017; Published May 30, 2017 Abstract: To explore the brainstem injury associated with supratentorial lesions, we conducted analysis of ICP levels and detected ENG parameters by using the cold caloric reflex test and histopathological examinations of the brain- stem. Rat model of intracerebral hemorrhage was well-established in the study of supratentorial lesions of varying severities (n=210). Intracerebral pressure monitoring and electronystagmography of the cold caloric reflex test were simultaneously performed in animals. Apoptotic, immunohistochemical, and histopathological changes in different segments of the brainstem were investigated at various time intervals. Electronystagmography parameters were analyzed by cold caloric reflex test. The result showed that the increase of intracerebral pressure was correlated with lesion severity including elevating levels and rostral-caudal progression of neuronal apoptosis, demyelination, N-methyl-D-aspartate cell receptor down-regulation (r=0.815), and histopathological changes. -
