motor tics
Uncontrolled muscle jerks
Motor tics are sudden, repetitive, involuntary movements—eye blinking, facial grimacing, shoulder shrugging, head jerking.
They differ from verbal tics, which produce sounds.
Motor tics range from simple (involving one muscle group) to complex (coordinated sequences like touching or jumping).
They're characteristic of Tourette syndrome but occur in other conditions and sometimes appear transiently in children.
