A novel exaggerated "spino-bulbo-spinal like" reflex of lower brainstem origin.

TLDR
The reflex described is likely an exaggerated normal reflex, likely triggered by a dolichoectatic vertebral arterial compression and shares characteristics of different reflexes known to originate in caudal brainstem, which subserve distinctive roles in human postural control.About:

Myoclonus: An Electrophysiological Diagnosis.
Shabbir Hussain Merchant,Felipe Vial-Undurraga,Giorgio Leodori,Jay A van Gerpen,Mark Hallett +4 more
TL;DR: Many different movement disorders have similar “jerk‐like” phenomenology and can be misconstrued as myoclonus, but they have distinctive physiologic characteristics that can help refine categorization of jerk‐like movements.

TL;DR: A 36-year-old man with vertigo and nausea had difficulty standing, and was transported by an ambulance to the authors' hospital, where combination therapy using multiple antiepileptic drugs, such as low-dose carbamazepine, clonazepam, and lacosamide, improved his clinical symptoms.

How to Do an Electrophysiological Study of Myoclonus
TL;DR: In this article , the authors provide detailed descriptions of recording poly-electromyography, combining electroencephalography and electromyography, Bereitschaftspotentials, somatosensory evoked potentials, and startle techniques.

TL;DR: In this paper , a review on myoclonus, tics, startle disorders, restless legs syndrome, and periodic leg movements during sleep can be performed with different validated scoring criteria with the help of electromyography.

Journal ArticleDOI
New observations on the normal auditory startle reflex in man.
TL;DR: The pattern of recruitment of cranial muscles suggests a brainstem origin for the normal startle response, and studies on the auditory startle reflex in animals are reviewed in the light of this finding.
Journal ArticleDOI
Cortical reflex myoclonus
TL;DR: It is argued that this type of myoclonus is mediated in cerebral cortex and that the negative transient represents a paroxysmal depolarization shift (PDS) and may result from hyperactivity of a component of the long-latency stretch reflex.
Journal ArticleDOI
The hyperekplexias and their relationship to the normal startle reflex.
TL;DR: The startle response to unexpected auditory and somaesthetic stimulation was studied in patients with hereditary or symptomatic hyperekplexia and it was abnormal in its resistance to habituation and in its exaggerated motor response, suggesting a brainstem origin for the abnormal startle responses.
Reticular reflex myoclonus: aphysiological typeof humanpost-hypoxic myoclonus
TL;DR: A patient with post-hypoxic myoclonus, sensitive to therapy with 5-hydroxytryptophan and clonazepam, was subjected to detailed electrophysiological investigation.
