Quantitative movement analysis of extent of wrist movements identifies hypermotor seizures in a non-selected sample of focal epileptic motor seizures

To evaluate the sensitivity and specificity of a novel quantitative analysis of movements during epileptic seizures for the identification of different motor seizures. We included 100 randomly selected videos of epileptic motor seizures recorded in the epilepsy monitoring unit in patients. Only videos were included, 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). Extent and…
