abstract = {Subthalamic deep brain stimulation (STN-DBS) can ameliorate
gait disturbances in Parkinson's disease (PD). Using motor
imagery and positron emission tomography (PET), we
investigated how STN-DBS interacts with supraspinal
locomotor centers in PD.Ten PD patients with bilateral
STN-DBS actually walked or stood still under STN-DBS ON or
OFF conditions. Directly thereafter, subjects imagined
walking or standing while changes in regional cerebral blood
flow were measured by PET.Independent of STN-DBS, imagined
walking distance correlated with imagery duration. Compared
with STN-DBS OFF, STN-DBS ON improved actual gait and
increased imagined walking distance. Imagery of gait (vs.
stance) induced activity in the supplementary motor area and
the right superior parietal lobule for both STN-DBS
conditions. The improvement of imagined gait during STN-DBS
ON led to activity changes in the pedunculopontine
nucleus/mesencephalic locomotor region (PPN/MLR).Data
suggest that STN-DBS improves Parkinsonian gait by
modulating PPN/MLR activity. © 2015 International Parkinson
