The idea is to mesh the patient's nervous system with prosthetic electronics, with an eye to reducing pain and improving control.

A Swedish woman who lost her right hand in a farming accident was outfitted with a first-of-its-kind bionic appendage six years ago that has fully integrated with the patient's own nerves, bones, and muscles.

An international research team reported that a robotic hand attached to a Swedish woman in 2017 has fully integrated with her nerves, bones, and muscles since the procedure.

The patient, who lost her right hand in a farming accident more than two decades ago, reported significant gains in function, a substantial reduction in phantom pain, and the absence of stump pain.

Lead researcher Max Ortiz-Catalan of Sweden's Center for Bionics and Pain Research said the robotic hand is connected directly to her skeleton using osseo (bone)-integrated implants, which allow the prosthesis and the electrodes implanted in nerves and muscles to communicate.

The electrodes collect information about localized nerve control, which is transmitted externally to a computer that uses artificial intelligence software to guide hand use.
