Artificial intelligence is helping people regain their mobility after certain neurological injuries. A robotic harness controlled by a neural network offers tailored treatment that has immediately improved their ability to walk normally.

The new smart harness, developed by researchers from NCCR Robotics at the Swiss Federal Institute of Technology in Lausanne and the Lausanne University Hospital, can also correct a person's gait by pushing them forward or back, or side to side.

It does this after collecting information on leg movement, stride and muscle activity from body sensors and feeding it into an algorithm. The harness then provides support tailored to the way the person walks, deciding how much force to apply to their trunk to produce a natural gait.
