Pictured: Harmonie-Rose Allen before the meningitis.
An eight-year-old meningitis survivor and quadruple amputee has become the youngest person in the world to be fitted with microprocessor knees.
The clever prosthetics contain tiny computers and sensors that allow Harmonie-Rose Allen to now do things most people take for granted.
The sensors in the legs take readings 100 times a second and can make real-time changes to control the movement and resistance through the use of hydraulics.
