During this paralysis, one cannot move and cannot say ...
[8] [9] Fainting may have acted as a form of tonic immobility, [8] allowing primitive humans to play dead in a situation where blood was being spilled, perhaps helping them to avoid the attention of enemies. It has also been suggested that the drop in blood pressure associated with seeing blood — as with an individual seeing blood from their ...
Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder.The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles and rigidity. [1]
Tonic immobility has also been observed in several species of lizards and snakes. [42] [43] The most common example of tonic immobility in the latter is the North American hog-nose snake, but it has also been observed in grass snakes. [42] Tonic immobility can be reliably induced in iguanas by a combination of inversion, restraint and moderate ...
Drugs that interfere with nerve function, such as curare, can also cause paralysis. Pseudoparalysis ( pseudo- meaning "false, not genuine", from Greek ψεῦδος [ 7 ] ) is voluntary restriction or inhibition of motion because of pain, incoordination, orgasm, or other cause, and is not due to actual muscular paralysis.

Treatment quinine, stretching, massage, and drinking liquids A cramp is a sudden, involuntary, painful skeletal muscle contraction [ 1 ] [ 2 ] or overshortening associated with electrical activity; [ 3 ] while generally temporary and non-damaging, they can cause significant pain and a paralysis -like immobility of the affected muscle.
Waxy flexibility often develops with other symptoms of catatonia, including: Immobility: showing no signs of motion [6] Posturing: holding in an inappropriate body position for an extended period of time [6] Mutism: lack or absence of speaking [6] Ambitendency: a pattern of incomplete motor responses in anticipation of a voluntary action [6]
Treatment for narcolepsy and cataplexy can be divided to those that act on the excessive daytime sleepiness (EDS) and those that improve cataplexy. Most patients require lifelong use of medications. [15] Most treatments in humans will act only symptomatically and do not target the loss of the orexin-producing neurons. [16]
