gegenhalten

[gā′gənhäl′tən]
Etymology: Ger, counterpressure
the involuntary resistance to passive movement of the extremities. It may occur as a symptom of catatonia, in which there is passive resistance to stretching movements, even when the patient attempts to cooperate. The effect may be psychogenic in origin or may be a sign of dementia or cerebral deterioration. Also called paratonia.
Involuntary ('active') resistance to passive movement, that increases with velocity of movement and continues through the full arc of motion; gegenhalten may be due to diffuse forebrain dysfunction, as occurs in anterior cerebral artery occlusion—‘arteriosclerotic parkinsonism’—or pseudoparkinsonism, and may be accompanied by grasp reflex
