Advanced parametrization of graphomotor difficulties in school-aged children
(IEEE, 2020-06-17)
School-aged children spend 31–60% of their time at school performing handwriting, which is a complex perceptual-motor skill composed of a coordinated combination of fine graphomotor movements. As up to ...
Analysis of various fractional order derivatives approaches in assessment of graphomotor difficulties
(IEEE, 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, ...
Comparison of CNN-learned vs. handcrafted features for detection of Parkinson's disease dysgraphia in a multilingual dataset
(Frontiers Media S.A., 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 ...
Exploiting spectral and cepstral handwriting features on diagnosing Parkinson’s disease
(IEEE, 2021-10-22)
Parkinson’s disease (PD) is the second most frequent neurodegenerative disease associated with several motor symptoms, including alterations in handwriting, also known as PD dysgraphia. Several computerized ...
A comparative study of in-air trajectories at short and long distances in online handwriting
(Springer Nature, 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 ...
Quantitative analysis of relationship between hypokinetic dysarthria and the freezing of gait in Parkinson’s disease
(Springer Nature, 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 ...
Changes in phonation and their relations with progress of Parkinson’s disease
(MDPI, 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
(MDPI, 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 ...
