- Abstract
A 22-year-old patient presented with attacks of paroxysmal dystonia characterised by involuntary and uncontrollable movements affecting lower and upper limbs with sustained turning or twisting of the trunk. These motor paroxysms were induced by voluntary movements and lasted between 10 and 15 s with a frequency of 1–5 attacks per day. Transcranial magnetic stimulation of the motor cortex was found to induce motor paroxysms very similar to the spontaneous attacks. To evaluate motor cortex and brainstem excitability immediately after and between the attacks, a neurophysiological study was performed.
