Pseudochoreoatheotosis:Movement Associated with Loss of Proprioception
Arch Neurol 51:1103-1109, Sharp,F.R.,et al, 1994
See this aricle in Pubmed

Article Abstract
These cases suggest that proprioceptive sensory loss can lead to a movement disorder,termed pseudochoreoathetosis,which occurs following the appearance of lesions anywhere along proprioceptive sensory pathways,from peripheral nerves to the cerebral cortex.It is hypothesized that pseudochoreoathetosis occurs because of the failure to process limb proprioceptive information in the striatum.Therefore,both choreoathetosis and pseudochoreoathetosis may be manifestations of the failure of the striatum to properly integrate cortical motor and sensory inputs.
