    The study included 56 patients, with myoclonus diagnosed in 55% and tremor in 36% of cases.

  • 3

    Initial clinical diagnoses were confirmed in 62% of patients, with many tremor cases reclassified as myoclonus.

  • 4

    Polymyography revealed additional movement disorders in 18% of patients, supporting a neurofunctional etiology in one case.
