Acoustic reflex abnormalities in cranial‐cervical dystonia
Neurology, 1992Previous anatomic and physiologic studies suggest brainstem dysfunction in cranial-cervical dystonia. To further explore this, we studied suprathreshold acoustic reflex waveforms in 15 such patients. A unique feature of this technique is its ability to reject movement artifacts before averaging the acoustic reflex waveforms.

Abnormal cough reflex in canine acrylamide neuropathy
Annals of Neurology, 1989AbstractCoughing in response to irritation of the airways is a fundamental protective reflex that is dependent on rapidly adapting bronchopulmonary receptors and their vagal afferent fibers; reflex airway constriction, which is effected by vagomotor efferent fibers, usually accompanies coughing.

Abnormal vestibulo-ocular reflex
2015Abstract This is a chapter on Abnormal vestibulo-ocular reflex from the Eyes/Eye Movements section of A Manual of Neurological Signs. Most of the chapters contain a description of the sign, associated signs, and cases, supported by clinical videos and figures.

Abnormalities of the acoustic reflex in multiple sclerosis
American Journal of Otolaryngology, 1986Acoustic reflect morphology was examined in 122 patients with a diagnosis of definite multiple sclerosis. Abnormality in some dimension of acoustic reflex morphology was observed in 75 per cent of the study population. The most commonly observed abnormality was an alteration in one or more of the three relative amplitude indices (afferent, efferent, or

The Vestibulo-Collic Reflex is Abnormal in Migraine
Cephalalgia, 2007Interictal evoked central nervous system responses are characterized in migraineurs by a deficit of habituation, at both cortical and subcortical levels. The click-evoked vestibulo-collic reflex (VCR) allows the assessment of otolith function and an oligosynaptic pathway linking receptors in the saccular macula to motoneurons of neck muscles.

JAMA: The Journal of the American Medical Association, 1966
To the Editor: In 1959 Dr. A. Diakiogiannis of Thessalonica reported an abnormal reflex sign which I believe is of significant diagnostic value. The reflex is attributed to damage of the pyramidal tracts at the spinal cord level. The sign can be elicited by lightly scratching the skin along the outer border of the tibia then down the dorsum of the ...

Abnormal middle ear muscle reflexes and audiosensitivity
British Journal of Audiology, 1986Reversed or hyperactive stapedial reflexes are found in a wide variety of patients complaining of audiosensitivity, defined as a need to turn down the volume on audio equipment. This was checked in an independent sample of children with learning problems.

Publisher Summary This chapter explains reflex activity, which is loosely defined as an involuntary response to the passage of nervous impulses through a reflex arc that enters into a wide range of somatic and visceral functions both in health and disease.

Medullary infarcts may cause ipsilateral masseter reflex abnormalities
Muscle & Nerve, 2007AbstractThere is a suprasegmental influence on the masseter reflex (MassR) in animals, which is mediated via the fifth nerve spinal nucleus (5SpN). Corresponding data in humans are lacking. Out of 268 prospectively recruited patients with clinical signs of acute brainstem infarctions, we identified 38 with magnetic resonance imaging (MRI)–documented ...
