Automatic non-linear analysis of non-invasive writing signals, applied to essential tremor

Essential tremor (ET) in the western world is the most common movement disorder, and 50–70% of essential tremor cases are estimated to be genetic in origin [14]. This work on selection of nonlinear biomarkers derived from drawings and handwriting is part of a wider cross-study for the diagnosis of essential tremor led by Biodonostia Institute. These biomarkers include not only classic linear features, but also non-linear: fractal dimension and...
