LOCALIZATION VALUE OF ICTAL TURNING PRONE

Ictal turning prone (ITP) was first described by Saygi et al as an ictal feature of frontal lobe “complex partial seizures” that distinguished them from psychogenic nonepileptic seizures with otherwise similar semiology [1]. Ictal turning prone can be considered a variation on “ictal body turning along the horizontal axis” described by Leung et al as a sign that helped further localize frontal lobe complex partial seizures [2]. Ictal body turning along the horizontal axis was defined as “truncal turning without any tonic element of the extremities for 90° or more, parallel to the body axis and horizontally”.
