Automatic classification of hyperkinetic, tonic, and tonic-clonic seizures using unsupervised clustering of video signals
Ojanen, Petri; Kertész, Csaba; Morales, Elizabeth; Rai, Pragya; Annala, Kaapo; Knight, Andrew; Peltola, Jukka (2023)
articleIntroduction: This study evaluated the accuracy of motion signals extracted from video monitoring data to differentiate epileptic motor seizures in patients with drug-resistant epilepsy. 3D near-infrared video was recorded ... -
Characteristics of motion signal profiles of tonic–clonic, tonic, hyperkinetic, and motor seizures extracted from nocturnal video recordings
Ojanen, Petri; Kertész, Csaba; Peltola, Jukka (2024)
articleObjective: In this study, characteristics of signal profiles formed by motion, oscillation, and sound signals were analyzed to evaluate generalizability and variability in a single patient setting (intra-patient variability) ... -
Feasibility of video/audio monitoring in the analysis of motion and treatment effects on night-time seizures : Interventional study
Ojanen, Petri; Zabihi, Morteza; Knight, Andrew; Roivainen, Reina; Lamusuo, Salla; Peltola, Jukka (08 / 2022)
articleThe aim of the study: This pilot study assessed the ability of a video/audio-based seizure monitoring system to evaluate (I) baseline frequency and severity of nocturnal seizures with motor features in patients with ... -
An integrative method to quantitatively detect nocturnal motor seizures
Ojanen, Petri; Knight, Andrew; Hakala, Anna; Bondarchik, Julia; Noachtar, Soheyl; Peltola, Jukka; Kaufmann, Elisabeth (01 / 2021)
articleIn this proof-of-concept investigation, we demonstrate a marker-free video-based method to detect nocturnal motor seizures across a spectrum of motor seizure types, in a nighttime setting with a single adult female with ...
