Laser light visual cueing for freezing of gait in Parkinson disease: A pilot study with male participants.

Freezing of gait (FOG) is a debilitating feature of Parkinson disease (PD). In this pilot study, we sought to assess the efficacy of a rolling walker with a laser beam visual cue to treat FOG in PD patients. We recruited 22 subjects with idiopathic PD who experienced on- and off-medication FOG.

Falling in Parkinson disease: identifying and prioritizing risk factors in recurrent fallers.

Objectives: To identify falling risk factors in a study population of recurrent fallers compared with nonfallers who have Parkinson disease, and to prioritize falling risk factors in this patient population to target them for modification.

Design: Twenty-three recurrent fallers and 25 nonfallers who have Parkinson disease were recruited, and they participated in a comprehensive assessment probing for the presence of falling risk factors. To identify falling risk factors, a group comparative design was used to compare recurrent fallers and nonfallers across an array of variables.
