According to a study on sleep disturbances in the Journal of Neural Transmission, a hypnic jerk occurs during the non-rapid eye movement sleep cycle and is an "abrupt muscle action flexing movement, generalized or partial and asymmetric, which may cause arousal, with an illusion of falling". [13]
A tremor is an involuntary, [1] somewhat rhythmic muscle contraction and relaxation involving oscillations or twitching movements of one or more body parts. It is the most common of all involuntary movements and can affect the hands, arms, eyes, face, head, vocal folds, trunk, and legs.

[ 12 ] In mild cases, ET can manifest as the inability to stop the tongue or hands from shaking, the ability to sing only in vibrato , and difficulty doing small, precise tasks such as ...
Sleep myoclonus occurs during the initial phases of sleep, especially at the moment of dropping off to sleep, and include familiar examples of myoclonus such as the hypnic jerk. Some forms appear to be stimulus-sensitive. Some people with sleep myoclonus are rarely troubled by it, or need treatment.
Treatment for Holmes tremor is dependent on the characteristics of the tremor. Because the disease is involved with the dopaminergic system, most treatments involve levodopa. [1] Drugs used to treat other types of tremors are applicable to the treatment of Holmes tremor; however, these drugs have a low success rate. [3]
Periodic limb movement disorder (PLMD) is a sleep disorder where the patient moves limbs involuntarily and periodically during sleep, and has symptoms or problems related to the movement. PLMD should not be confused with restless legs syndrome (RLS), which is characterized by a voluntary response to an urge to move legs due to discomfort.
A confusional arousal (also known as sleep drunkenness or severe sleep inertia) is medical condition where a person awakened from sleep shows mental confusion for at least several minutes. [ 1 ] [ 2 ] Complete or partial amnesia of the episodes may be present.
