    Bilateral double beta peaks were observed in a Parkinson's disease patient with subthalamic nucleus electrodes during long-term local field potential recordings.

  • 2

    The patient exhibited distinct beta peaks at 15 Hz and 25 Hz, which were suppressed by stimulation and gait, with a novel 13 Hz peak emerging on the right side.

  • 3

    Deep brain stimulation significantly improved the patient's symptoms, as indicated by a reduction in UPDRS III scores from 38 to 7.

  • 4

    LFP analysis revealed that stimulation on the left side led to a gradual reduction of both beta peaks, while the right side showed a unique response to increased stimulation.

  • 5

    Gait performance monitoring indicated that stimulation completely suppressed beta peaks on the left side, while only partially suppressing them on the right side.
