Zothecula writes with this excerpt from GizMag: "Studies have shown that a large percentage of amputees feel pain in their missing limbs. ... The ailment has so far proven difficult to treat, but a new study suggests therapy involving augmented reality and gaming could stimulate these unused areas of the brain (full journal article), resulting in a significant reduction in discomfort. ... In testing the treatment, the team used myolectric pattern recognition to predict phantom movements in the stump of a chronic PLP patient. By using the patterns as inputs in an augmented setting where a virtual arm was superimposed on the patient's real-life body, as well as controlling a car racing game, the team were able to gradually reduce the pain reported by the patient to zero."
The study is an early one: there's only a single test subject, but
one that had no success with any other form of treatment.
