A unique movement disorder causing involuntary spasms only when lying down was identified in a 59-year-old man. Clinical and electrophysiological data suggest it is a distinct form of simple tic, now termed "recumbent tic".

Area of Science:

  • Neurology
  • Movement Disorders
  • Clinical Electrophysiology

Background:

  • Movement disorders present a diagnostic challenge, particularly rare conditions with atypical symptoms.
  • Understanding the spectrum of tic disorders is crucial for accurate diagnosis and management.

Observation:

  • A 59-year-old male patient presented with a 30-year history of involuntary axial spasms.
  • These spasms exclusively occurred when the patient was in a recumbent (lying down) position.

Findings:

  • Clinical examination and electrophysiological studies were performed to characterize the movement disorder.
  • The evidence strongly suggests the condition is a simple tic exhibiting an unusual presentation.

Implications:

  • The identification of this distinct condition necessitates the coining of a new term: "recumbent tic".
  • This case expands the known phenomenology of tic disorders and may inform future diagnostic criteria.
  • Further research into the neurobiological underpinnings of "recumbent tic" is warranted.
