 Purpose of the experiment Up to 50-80 of persons with amputations experience pain in the part of the body that is missing. This phenomenon is called phantom limb pain. It is not clear today why phantom limb pain occurs, and since the pain can be difficult to treat, it can affect the quality of life. Other scientific studies have shown, that the use of electrical stimulation applied through surface electrodes, can assist to decrease or alleviate the phantom limb pain. The aim of this study is to investigate if surface electrical stimulation for a period of 3 months can decrease or alleviate the phantom limb pain.
