RT Journal Article SR Electronic T1 Disappearance of “phantom limb” and amputated arm usage during dreaming in REM sleep behaviour disorder JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr0920080851 DO 10.1136/bcr.09.2008.0851 VO 2009 A1 Vetrugno, Roberto A1 Arnulf, Isabelle A1 Montagna, Pasquale YR 2009 UL http://casereports.bmj.com/content/2009/bcr.09.2008.0851.abstract AB Limb amputation is followed, in approximately 90% of patients, by “phantom limb” sensations during wakefulness. When amputated patients dream, however, the phantom limb may be present all the time, part of the time, intermittently or not at all. Such dreaming experiences in amputees have usually been obtained only retrospectively in the morning and, moreover, dreaming is normally associated with muscular atonia so the motor counterpart of the phantom limb experience cannot be observed directly. REM sleep behaviour disorder (RBD), in which muscle atonia is absent during REM sleep and patients act out their dreams, allows a more direct analysis of the “phantom limb” phenomena and their modifications during sleep.
