Recumbent tic

Movement Disorders, 1992
AbstractA 59‐year‐old man with a 30‐year history of an unusual movement disorder characterised by involuntary axial spasms that occur only in recumbency is described. Clinical and electrophysiological evidence suggest that this disorder is best characterised as a simple tic of unusual form.

Tic Disorders

Continuum, 2013
Primary tic disorders are complex, multifactorial disorders in which tics are accompanied by other sensory features and an array of comorbid behavioral disorders. Secondary tics are proportionally much less frequent, but their etiology is diverse.
