Prosthetic limb restores sense of touch, heals phantom pain

A new prosthetic limb can restore sensation for people who have lost a limb and even relieve the phantom pains they feel, LiveScience reports. Developed by researchers at Cleveland’s Case Western Reserve and the government’s APT Center, the prosthesis stimulates the nerves in a patient’s upper arm, allowing them to once again experience the sense of touch.

A new prosthetic limb can restore sensation for people who have lost a limb and even relieve the phantom pains they feel, LiveScience reports. Developed by researchers at Cleveland’s Case Western Reserve and the government’s APT Center, the prosthesis stimulates the nerves in a patient’s upper arm, allowing them to once again experience the sense of touch.

The underlying research is spotlighted in this week’s issue of Science Translational Medicine, titled: “A neural interface provides long-term stable natural touch perception.”

LiveScience writes:

It’s not the first prosthetic to restore touch to an amputee, but it may provide a more “natural” sensation than earlier devices, said head researcher Dustin Tyler, a biomedical engineer at Case Western Reserve in Cleveland, Ohio. The device’s system has now been in testing for more than two years.
