A portable, battery-powered laser device has been developed in Singapore to help people suffering from Parkinson’s disease regain their walking rhythm.

Parkinson’s is a slow, degenerative disease that deprives sufferers of steady movement, leading to jerky small steps or freezing up in narrow spaces, the team said. To take the next step, patients need a cue.

The device, which generates cues telling patients when and how to walk, shoots a red laser beam on the ground, creating a path.
