    • Analysis of various fractional order derivatives approaches in assessment of graphomotor difficulties 

      Mucha, Ján; Mekyska, Jiri; Galaz, Zoltan; Faundez-Zanuy, Marcos; Zvončák, Vojtěch; Zvončáková, Katarína; Urbanek, Tomas; Havigerova, Jana Marie; Bednarova, Jirina; Smekal, Zdenek (IEEE Access. 2020 Dec 4; 8:218234-218244, 2020-12-04)
      Graphomotor disabilities (GD) are present in up to 30% of school-aged children and are associated with several symptoms in the field of kinematics. Although the basic kinematic features such as velocity, ...

    • 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 ...

    • Comparison of CNN-learned vs. handcrafted features for detection of Parkinson's disease dysgraphia in a multilingual dataset 

      Galaz, Zoltan; Drotar, Peter; Mekyska, Jiri; Gazda, Matej; Mucha, Jan; Zvoncak, Vojtech; Smekal, Zdenek; Faundez-Zanuy, Marcos; Castrillon, Reinel; Orozco-Arroyave, Juan Rafael; Rapcsak, Steven; Kincses, Tamas; Brabenec, Lubos; Rektorova, Irena (Frontiers in Neuroinformatics. 2022;(16):877139, 2022)
      Parkinson’s disease dysgraphia (PDYS), one of the earliest signs of Parkinson’s disease (PD), has been researched as a promising biomarker of PD and as the target of a noninvasive and inexpensive ...

    • 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 ...
