Abstract

Background: Functional movement disorder (FMD) is increasingly being recognized as a condition associated with abnormal brain network connectivity; however, effective treatment strategies remain limited.

Methods: We report the case of a patient with severe FMD that developed following an occupational injury and was characterized by functional tremors accompanied by migraines and prominent autonomic symptoms. Based on electroencephalography (EEG) network analysis, low-frequency repetitive transcranial magnetic stimulation targeting the supplementary motor area was administered, followed by staged rehabilitation incorporating visual feedback.

Results: The combined intervention reduced tremors and improved gait speed, activities of daily living, and EEG network connectivity.

Conclusion: This case highlights the potential utility of combining EEG-guided neuromodulation with staged rehabilitation for the treatment of FMD and supports further investigation of this approach.
