Phantom limb sensations and related phenomena are frequent consequence
s of the amputation of an extremity. Although the mechanisms underlyin
g painless and painful phantom sensations in amputees have been discus
sed over the years, and are still a matter of dispute, that responsibl
e for the generation of these phantom feelings is not well understood.
However, there have been a number of attempts to explain, within a th
eoretical framework, the origin of phantom limb sensations and related
phenomena. This paper reviews some of the most tenable explanations,
along with the work so far completed on this issue. (C) 1998 Lippincot
