Article Synopsis
- Researchers tested deep brain stimulation (DBS) of the pedunculopontine nucleus (PPN) to treat freezing of gait (FOG) in Parkinson's disease (PD), noting varied patient responses possibly linked to electrode placement.
- The study aimed to correlate the effects of DBS in the caudal mesencephalic reticular formation (cMRF) with patient outcomes, using a normalized brainstem coordinate system for accurate positioning.
- Results indicated that the best effects for treating FOG were achieved with electrode contacts in the posterior cMRF, particularly near the pontomesencephalic junction, leading to recommendations for optimal DBS targeting.
Objective: To assess, in a cross-sectional study, the feasibility and immediate efficacy of laser shoes, a new ambulatory visual cueing device with practical applicability for use in daily life, on freezing of gait (FOG) and gait measures in Parkinson disease (PD).
Methods: We tested 21 patients with PD and FOG, both "off" and "on" medication. In a controlled gait laboratory, we measured the number of FOG episodes and the percent time frozen occurring during a standardized walking protocol that included FOG provoking circumstances.
Background: Freezing of gait (FOG) is a mysterious, complex and debilitating phenomenon in Parkinson's disease. Adequate assessment is a pre-requisite for managing FOG, as well as for assigning participants in FOG research. The episodic nature of FOG, as well as its multiple clinical expressions make its assessment challenging.
