Summary

Deep brain stimulation (DBS) of the globus pallidus internus (GPi) offers functional benefits for disabling camptocormia. Long-term pallidal stimulation is safe and improves patient mobility and neuropsychological scores.

Area of Science:

  • Neurology
  • Neurophysiology
  • Neuropsychology

Background:

  • Camptocormia is a disabling condition characterized by severe trunk flexion.
  • Deep brain stimulation (DBS) is a potential therapeutic option for movement disorders.

Observation:

  • Bilateral high-frequency DBS targeting the globus pallidus internus (GPi) was performed in a patient with disabling camptocormia.
  • Neurological, neurophysiological, and neuropsychological assessments were conducted before and after GPi stimulation.
  • Local field potentials (LFPs) from GPi and electromyography (EMG) of abdominal muscles were recorded.

Findings:

  • Significant functional improvement and some neuropsychological score enhancement were observed after 6 months of GPi stimulation.
  • A temporal correlation was noted between GPi LFPs and rectus abdominis EMG activity during camptocormic episodes.

  • No treatment-related adverse effects were reported, indicating safety.

    • Implications:

    • Long-term pallidal stimulation is a safe and effective treatment for disabling camptocormia.
    • This study provides insights into the pathophysiology of camptocormia through physiological recordings.
    • DBS may offer a viable therapeutic strategy for this rare and severe condition.
