 Methods Before the study begins, it will be necessary to test if the participant can tolerate the electrical stimulation and that the participant fulfill all criteria for participating in the study. During the study, different electrical stimulation sequences will be applied. The participant will be asked to fill out a series of questionnaires before, during and after the electrical stimulation, to describe how the electrical stimulation is experienced, and if the stimulation had an effect on the phantom limb pain and phantom sensations. The participant will also be asked about their general mood to investigate if this has an effect on the pain. The brain signals of the participants will be measured twice with either surface electrodes or with a scanning technique, while the participant is thinking about moving the amputated armhand, while moving the healthy arm, or while receiving electrical stimulation.
