title: [Automated two-point discrimination (TPD) for phantom pain : Effect of a 3‑week automated therapy based on TPD for a transtibial amputee with phantom pain].
abstract: There is preliminary evidence that phantom pain is associated with disturbed organization of the sensory cortex and that this organization can be normalized with two-point discrimination (TPD) training. In this case study, a reduction in phantom pain and painful phantom sensation during a test period of 19 days, was achieved using an automated TPD procedure. In a patient with a transtibial amputation, pain levels decreased from a mean of 2.3/10 on the visual analog scale (VAS) to 1.3/10 (VAS) and the painful phantom sensation level decreased from a mean 3.7/10 (VAS) to 2.0/10 (VAS). These results show a positive trend, but are (except of the nocturnal pain attacks) rather of limited clinical relevance.
