Descriptive Study of Receptive Fields in Lower Limb Amputees

It has been observed that patients subjected to amputations develop so called receptive fields, which time of occurrence and localization over time are yet not examined systematically. This clinical trial aims to investigate the reliability in detecting these receptive fields as well as their incidence and changes over time. Further it aims to evaluate the acute effect of a stimulating system ("Phantom Stimulator" (Cort X Sensorics, Spaichingen, Germany)) on selected gait parameters measured tough a gait analysis system ("OprtoGait" (Microgate, Bolzano, Italy)) as well as on phantom sensations measured through a questionnaire.
