Dual-Task Improvement in Parkinson's Via rTMS

Parkinson's disease often leads to declines in cognition, gait performance, and the ability to manage simultaneous cognitive-motor demands. These difficulties contribute to mobility limitations, fall risk, and loss of independence in older adults. This randomized controlled study investigates whether repetitive transcranial magnetic stimulation (rTMS) targeting the left dorsolateral prefrontal cortex can enhance cognitive function and improve single- and dual-task mobility performance in individuals with Parkinson's disease. Participants complete a two-week intervention consisting of active or sham stimulation. Standardized cognitive and functional mobility assessments are administered before and after the intervention to determine the extent of change associated with rTMS. The study is designed to provide preliminary evidence on whether neuromodulation of an executive-control region can support functional motor-cognitive interactions in this population.
