Double amputee walks again due to Bluetooth

There have been many attempts and solutions to make efficient prosthetic legs for amputees. Recently, two military amputees were given the latest, innovative prosthetic legs. The prosthetic limb is equipped with Bluetooth receivers at the ankles, which has previously been used to allow a single prosthetic leg to mimic the individual's other leg but, in this case, is being use to allow one prosthetic leg to mimic the other. Since the Bluetooth is programmed to move consistently for each leg the stride length, speed and force for going uphill or downhill is balanced. They are initiated with the force of the thigh muscles to get things moving or slow them down, with built-in motors in the legs allowing him to walk longer without getting tired.
