    • A comparative study of in-air trajectories at short and long distances in online handwriting 

      Alonso-Martinez, Carlos; Faundez-Zanuy, Marcos; Mekyska, Jiri (Cognitive Computation. 2017;9:712–720, 2017)
      Existing literature about online handwriting analysis to support pathology diagnosis has taken advantage of in-air trajectories. A similar situation occurred in biometric security applications where the ...

    • Automatic analysis of Archimedes’ spiral for characterization of genetic essential tremor based on Shannon’s entropy and fractal dimension 

      López-de-Ipiña, Karmele; Solé-Casals, Jordi; Faundez-Zanuy, Marcos; Calvo, Pilar M.; Sesa-Nogueras, Enric; Roure Alcobé, Josep; Martinez de lizarduy, Unai; Beitia, Blanca; Fernandez, Elsa; Iradi, Jon; Garcia-Melero, Joseba; Bergareche, Alberto (Entropy. 2018;20(7):531, 2018-07-16)
      Among neural disorders related to movement, essential tremor has the highest prevalence; in fact, it is twenty times more common than Parkinson’s disease. The drawing of the Archimedes’ spiral is the ...

    • Changes in phonation and their relations with progress of Parkinson’s disease 

      Galaz, Zoltan; Mekyska, Jiri; Zvoncak, Vojtech; Mucha, Jan; Kiska, Tomáš; Smekal, Zdenek; Eliasova, Ilona; Mrackova, Martina; Kostalova, Milena; Rektorova, Irena; Faundez-Zanuy, Marcos; Alonso-Hernández, Jesús B.; Gomez-Vilda, Pedro (Applied Sciences. 2018;8(12):2339, 2018-11-22)
      Hypokinetic dysarthria, which is associated with Parkinson’s disease (PD), affects several speech dimensions, including phonation. Although the scientific community has dealt with a quantitative analysis ...

    • Identification and monitoring of Parkinson’s disease dysgraphia based on fractional-order derivatives of online handwriting 

      Mucha, Ján; Mekyska, Jiri; Galaz, Zoltan; Faundez-Zanuy, Marcos; López-de-Ipiña, Karmele; Zvoncak, Vojtech; Kiska, Tomáš; Smekal, Zdenek; Brabenec, Lubos; Rektorova, Irena (Applied Sciences. 2018;8(12):2566, 2018-12-11)
      Parkinson’s disease dysgraphia affects the majority of Parkinson’s disease (PD) patients and is the result of handwriting abnormalities mainly caused by motor dysfunctions. Several effective approaches ...

    • Quantitative analysis of relationship between hypokinetic dysarthria and the freezing of gait in Parkinson’s disease 

      Mekyska, Jiri; Galaz, Zoltan; Kiska, Tomas; Zvoncak, Vojtech; Mucha, Jan; Smekal, Zdenek; Eliasova, Ilona; Kostalova, Milena; Mrackova, Martina; Fiedorova, Dagmar; Faundez-Zanuy, Marcos; Solé-Casals, Jordi; Gómez Vilda, Pedro; Rektorova, Irena (Cognitive Computation. 2018;10(6):1006-1018, 2018)
      Hypokinetic dysarthria (HD) and freezing of gait (FOG) are both axial symptoms that occur in patients with Parkinson’s disease (PD). It is assumed they have some common pathophysiological mechanisms and ...

    • Reliability and validity of the Polar V800 sports watch for estimating vertical jump height 

      Garnacho-Castaño, Manu; Faundez-Zanuy, Marcos; Serra Paya, Noemi; Maté-Muñoz, José Luis; López Xarbau, Josep; VILA BLANCH, MOISÈS (Journal of Sports Science and Medicine. 2021;(20):149-157, 2021)
      This study aimed to assess the reliability and validity of the Polar V800 to measure vertical jump height. Twenty-two physically active healthy men (age: 22.89 ± 4.23 years; body mass: 70.74 ± 8.04 kg; ...

    • Selection of entropy based features for automatic analysis of essential tremor 

      López-de-Ipiña, Karmele; Solé-Casals, Jordi; Faundez-Zanuy, Marcos; Calvo, Pilar Maria; Sesa-Nogueras, Enric; Martinez de lizarduy, Unai; Riva de la, Patricia; Marti Masso, Jose Felix; Beitia, Blanca; Bergareche, Alberto (Entropy. 2016;18(5):184, 2016)
      Biomedical systems produce biosignals that arise from interaction mechanisms. In a general form, those mechanisms occur across multiple scales, both spatial and temporal, and contain linear and non-linear ...
