Reference studies

The documentation and quantification of seizures is the primary outcome measure of epilepsy therapy including anti epileptic drug treatment, epilepsy surgery, and neurostimulation. There is increasing amount of data suggesting that traditional seizure diaries are highly unreliable and suffer from underreporting with sensitivities of 50% during day and as low as 30% during night. This inaccuracy forms a major issue for the assessment of treatment efficacy [1].

Recent academic research strongly supports video analysis as an objective measurement tool for motorised epileptic seizures [2], with evidence that these biomarkers can be used for risk analysis in patients with seizure symptoms [3]. Motion analysis, in particular, has been shown to be an effective technique for detecting the presence of a motor seizure with high sensitivity [4]. With emerging technologies based on deep learning, it is possible to build models not simply based on motion, but that of the human skeleton [5]. By combining traditional signal processing techniques with physical musculoskeletal models, a higher specificity on the type and severity of such seizures can be achieved.
