Primary progressive freezing gait with impressive response to laser light visual cueing: a video case report
Primary progressive freezing gait (PPFG) is a neurodegenerative atypical Parkinsonism disorder, initiated with start hesitation, episodic inability (lasting seconds) to generate effective stepping, leading to freezing of gait (FOG) without other neurological abnormalities within the first 3 years, and eventually postural instability, and falls. It is usually coupled with bradykinesia, rigidity, and levodopa resistance [1, 4, 5, 6].
We report a case of PPFG which experienced a dramatic improvement to the use of a laserlight visual cueing device (LVCD).
A 73-year-old woman was referred in 2016 regarding a gradual and progressive clinical picture initiated in 2012 with rapid transitory episodes of FOG (Online Resource 1), several falls, and since 2015 mild bilateral bradykinesia. Brain magnetic resonance imaging...
