A freezing of gait cue apparatus that provides a visual cue, and a method for providing a visual cue, upon detection of a gait irregularity. The gait irregularity, such as a freeze of gait (FOG) for sufferers of neurological diseases like Parkinson's disease, is determined by a processor in communication with a motion sensor worn by the sufferer. When the gait irregularity is determined the apparatus projects a laser light beam on the ground in front of the user of the apparatus to cue them to continue walking.
