English to Portuguese: On the classification of tremor signals into dyskinesia, Parkinsonian tremor, and Essential tremor by using machine learning techniques General field: Tech/Engineering Detailed field: Medical: Health Care
Source text - English Parkinson's disease is a neurological disorder that leads to motor symptoms, some of them being the typical Parkinsonian tremor (PT) and dyskinesia, which is characterized by random movements of the limbs that appear as medication side effect. Moreover, the Essential Tremor (ET) is a monosymptomatic disorder, usually confused with PT, due to frequency content overlap of both signals. Unified Parkinson’s Disease Rating Scale is used for the clinical assessment of PD. It considers the forms filled out with patients’ symptoms information and their physical evaluation. This scale is subjective due to the inter-rater variability, justifying the aim of the present work of developing a methodology to distinguish these three disorders. Thus, five machine learning algorithms - K-Nearest Neighbours (K-NN), Decision Trees (DT), Random Forest (RF), Naïve Bayes (NB) and Support Vector Machines (SVM) - were chosen for classification purposes. First, variables were extracted from the collected signals (mean, standard deviation, and amplitude peak in time; dominant and second dominant frequencies; first and second spectral peaks; correlation peak and instant time of it). Next, a Principal Component Analysis was carried out for reducing the data set to three components that explained 95% of the data variance, which were then used as inputs for the classification models. DT and RF showed highest accuracy (=1), followed by SVM (=0.9394) using the Gaussian kernel function, whereas K-NN and NB showed the lowest one (=0.8788). Considering also precision, recall, and F1-score, DT and RF were found to be the most appropriate models for this problem.
Translation - Portuguese A doença de Parkinson é um distúrbio que leva a sintomas motores, alguns deles sendo o Tremor Parkinsoniano (TP) e a Discinesia, que é caracterizada por movimentos aleatórios dos membros, que aparece como um efeito colateral da medicação. Além disso, o Tremor Essencial (TE) é um distúrbio monossintomático, geralmente confundido com TP, devido a sobreposição do conteúdo em frequência de ambos os sinais. A Escala Unificada de Avaliação da Doença de Parkinson é usada para a análise da PD. Ela considera os formulários que são preenchidos com os sintomas dos pacientes.
