"Smart"prosthetic legs can help amputees achieve a natural walking gait, but it's done through robotic sensors and algorithms that drive the limb forward at predetermined rates.

A better way would be to give people full control over the limb through their nervous system -- and that's just what an MIT research team says it's done.

An experimental surgical procedure combined with a cu...

Fifty years ago, the TV series "The Six Million Dollar Man"hyped a futuristic world of life-changing bionics with the stirring phrase: "We can rebuild him, we have the technology."

Cut to 2023, and researchers in Sweden appear to have delivered on that promise.

A Swedish woman who lost her right hand in a farming accident more than 20 years ago has successfully been outfitted with a...

A multinational team of engineers and surgeons has developed a bionic hand with a high level of function in every finger -- a significant advance for amputees.

The team, from the United States, Sweden, Australia and Italy, developed a way to reconfigure what remains of a patient's limb. Then, they integrated sensors and a skeletal implant to connect with a prosthesis both electrically an...

Former Marine Cpl. Claudia Mitchell can hold a banana or a water bottle in her left hand without squishing it as she opens it.

She can use her left hand to help cut peaches for a pie. She can hold someone's hand without squeezing too hard, and she can grab her makeup bag with just her thumb and forefinger.

Years ago, Mitchell, 41, wouldn't have imagined any of these feats were possi...
