Letter to the Editors

Dear Sirs,

Gait disturbances are among the most incapacitating symptoms in Parkinsonism syndromes because they are often refractory to medical and surgical treatments [1, 2, 3].

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...



We wish to thank the patient and her family for their cooperation regarding this report. We obtained written informed consent from the patient’s son for this publication.
