Abstract

Tremor is the most common movement disorder characterized by repetitive and stereotyped movements. Tremor can be classified in many ways, depending on its phenomenology, frequency and location. The data collection conducted under kinetic conditions and while performing a voluntary movement highlights the kinetic tremor. The analysis of hand-drawing movements is commonly used in the evaluation of patients with tremor. In this study, a number of features extracted from tremor activity, obtained from digitized drawings of Archimedes’ spirals, were analysed. The analyses followed the sequence bellow: 1 – Linearization of the spiral of Archimedes; 2 – Estimate of tremor activity; 3 – Data pre-processing; and 4 – Feature extraction from the tremor activity. The statistical analysis of the extracted features was able to prove the differences between physiological and essential tremors collected under kinetic conditions.
