Journal of neurosurgery·2025

Area of Science:

  • Neurosurgery
  • Neurology
  • Biomedical Engineering

Background:

  • Thalamic hand and myoclonus are debilitating neurological conditions.
  • Current treatments offer limited relief for these movement disorders.

Purpose of the Study:

  • To evaluate the efficacy and safety of chronic motor cortex stimulation (MCS) for thalamic hand and myoclonus.

Main Methods:

  • Five patients underwent MR-image-guided epidural electrode placement on the motor cortex.
  • A trial period preceded permanent implantation of a neurostimulator.
  • Intra-operative stimulation confirmed electrode placement.

Main Results:

  • Four out of five patients reported significant pain reduction.

  • Reduced dystonia, rigidity in thalamic hand, and myoclonus were observed.
  • No complications or adverse effects were reported.

    • Conclusions:

    • Chronic motor cortex stimulation is a safe and effective treatment for thalamic hand and myoclonus.
    • MCS offers a promising therapeutic option for refractory movement disorders.
