Focal hyperkinetic seizure

What it means

A focal seizure characterized at onset by predominantly proximal limb or axial muscles producing irregular sequential ballistic movements, such as pedaling, pelvic thrusting, thrashing, rocking movements.

The 2017 ILAE classification arbitrarily groups pedaling activity with hyperkinetic seizures, rather than with automatism seizures. However, some automatisms overlap other motor behaviors and where pedaling is slow and coordinated it may be considered an automatism.

Rare diseases that can present with this2

The range is how often this sign appears among people diagnosed with each disease — it is not a probability of having any of them. Many of these signs also occur in common, non-rare conditions. A sign on this page is a conversation to have with a clinician, not a conclusion.
