Cureus, 2021 Myoclonus is a sudden, involuntary jerking of a muscle or a group of muscles. Myoclonus may present in form of a pattern or, sporadically and infrequently. It is usually associated with neurological disorders such as epilepsy, multiple sclerosis or infections, and tumors of the central nervous system.

Functional jerks, tics, and paroxysmal movement disorders [PDF]
, 2016 Functional jerks are among the most common functional movement disorders. The diagnosis of functional jerks is mainly based on neurologic examination revealing specific positive clinical signs.

Jerks of the latissimus dorsi muscle and intercostal neuralgia after posterolateral thoracotomy
Clinical Neurophysiology Practice, 2021 Introduction: Post-thoracotomy pain syndrome (PTPS) is a common complication related to intercostal nerve injury. During this type of surgery, although less frequently, thoracodorsal and long thoracic nerves can also be injured, and jerks of peripheral ...

Electrophysiologic Evaluation of Psychogenic Movement Disorders [PDF]
Journal of Movement Disorders, 2011 Psychogenic movement disorders (PMD) are a group of disorders which are in the border zone between neurology and psychiatry. All necessary laboratory investigations should be done to rule out an underlying organic disorder.

Dynamics of temporal changes of geomagnetic field secular variations
Геофизический журнал, 2016 Time changes of the geomagnetic field secular variations, cleaned by three and eleven years running means were studying. The years of the changes of sign secular variations and years of the changes of their velocity were found.

Evidence for a geomagnetic jerk in 1990 across Europe
Annals of Geophysics, 1995 The analysis of geomagnetic data from magnetic observatories demonstrated the existence of very rapid changes, or jerks, in the secular variation, especially the occurrence of the well known geomagnetic jerks of 1969 and 1978.
