Brain-Machine Tech Helps Relieve Mysterious 'Phantom Limb Pain'

A new treatment appears to help relieve the "phantom limb pain" that people who have undergone amputations or have paralysis in a limb sometimes experience, a new study from Japan finds. In the study, the researchers used brain-machine-interface technology to treat patients who had phantom limb pain, which means they experience pain in a missing or paralyzed limb. The technology records a person's brain activity, and then translates that activity into the movement of a robotic prosthesis, accord
