Paralysis

Paralysis was the inability to move. Sutekh was imprisoned and paralysed in a tomb in Egypt; he used Marcus Scarman as his arms and legs to free himself. (TV: Pyramids of Mars)

Paralysis could occur from particularly violent movement or experiences; the Fourth Doctor was concerned that Sarah Jane Smith was paralysed following the two of them being caught in a quarry mine explosion. (TV: The Hand of Fear) Violent physical fighting and contact with points like the solar plexus could leave humans momentarily paralysed. (PROSE: Blood Harvest)

Biologically induced paralysis
Paralysis could also result from biological contact, with several substances being able to induce it. Unprotected contact with a spectrox nest resulted in spectrox toxaemia, beginning with a rash, followed by spasms then slow paralysis of spinal nerves and finally thermal death point. (TV: The Caves of Androzani)

Paralysis was a symptom of tetrodotoxin poisoning. (PROSE: Cat's Cradle: Warhead)

Paxx-Sinopli syndrome resulted in partial paralysis and then eventual death from cerebral emancipation. (PROSE: Dark Progeny)

Biological paralysis was not always fatal. Sleep paralysis was a method by which the human body prevented humans acting out their dreams whilst asleep. (PROSE: Dry Pilgrimage)

Technologically induced paralysis
Weapons technology could also be used to paralyse. The Sensorites', (TV: The Sensorites) the Quarks' (TV: The Dominators) and the Daleks' weapons (TV: "The Survivors") could be used to paralyse individuals.

Earth-based technology could also induce paralysis. Through the use of a taser gun or a stun gun, an individual could be stunned or paralysed, unable to move. (PROSE: Just War, Eternity Weeps, TV: End of Days)
