Quantified Analysis of Wrist and Trunk Movements Differentiates between Hypermotor and Automotor Seizures

We have attempted to evaluate the movement characteristics of hypermotor and automotor seizures based on an observer-independent objective method. We included EEG and video recorded automotor (n=10) and hypermotor seizures (n=10) of 17 patients considered for resective epilepsy surgery, in whom the camera position was perpendicular to the trunk facing the camera in an upright position and wrist and trunk movements were continuously visible on the video recordings. The movements were quantified from the videos by analyzing all video frames during the entire seizure (25/s). Seizure duration, movement angular speed…
