A case of involuntary spasm movements in amputation stump

Abstract

Painful jumping stump is characterized by persistent choreiform or myoclonic involuntary movements 
and severe neuropathic pain in the stump of a limb following amputation. This syndrome is also defined 
as„ trepidation du moignon‟, convulsive movements of the stump” or“jumpy stump”.The 
pathophysiology and etiology have not yet been clearly defined. We describe a seventy four year old 
man, who has severe neuropathic pain and involuntary muscle contractions in the amputation stump. 
We suggest that, there is a need for further clinical and electrophysiological investigations in order to 
understand that exact mechanisms play a role in the devolopment of the disorder.
