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.~A receptive field is defined as skin area anywhere on the same side of the body as the amputation, which when stimulated by others, causes phantom sensations in the amputated extremity.~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 the 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.
