Recurrence quantification analysis of postural sway in patients with persistent postural perceptual dizziness

Autor: Megan J. Kobel, Andrew R. Wagner, Daniel M. Merfeld

Publikováno v: Frontiers in Rehabilitation Sciences, Vol 4 (2023)

BackgroundPersistent postural perceptual dizziness (PPPD) is a common cause of chronic dizziness and imbalance. Emerging evidence suggests that changes in quantitative measures of postural control may help identify individuals with PPPD, however, tra

Effects of Frontal Theta Rhythms in a Prior Resting State on the Subsequent Motor Imagery Brain-Computer Interface Performance

Autor: Jae-Hwan Kang, Joosang Youn, Sung-Hee Kim, Junsuk Kim

Publikováno v: Frontiers in Neuroscience, Vol 15 (2021)

Dealing with subjects who are unable to attain a proper level of performance, that is, those with brain–computer interface (BCI) illiteracy or BCI inefficients, is still a major issue in human electroencephalography (EEG) BCI systems. The most suit

Optimal Feature Space Selection in Detecting Epileptic Seizure based on Recurrent Quantification Analysis and Genetic Algorithm

Autor: Saleh LAshkari, Mehdi Azarnoosh

Publikováno v: Journal of Intelligent Procedures in Electrical Technology, Vol 7, Iss 26, Pp 35-44 (2016)

Selecting optimal features based on nature of the phenomenon and high discriminant ability is very important in the data classification problems. Since it doesn't require any assumption about stationary condition and size of the signal and the noise

Introducing BisQ, A Bicoherence-Based Nonlinear Index to Explore the Heart Rhythm

Autor: José Luis Hernández-Caceres, René Iván González-Fernández, Marlis Ontivero-Ortega, Guido Nolte

Publikováno v: Mathematical and Computational Applications, Vol 25, Iss 3, p 45 (2020)

Nonlinear frequency coupling is assessed with bispectral measures, such as bicoherence. In this study, BisQ, a new bicoherence-derived index, is proposed for assessing nonlinear processes in cardiac regulation. To find BisQ, 110 ten-minute ECG traces

[EN] Many indices aimed at discriminating between paroxysmal and persistent atrial fibrillation (ParAF vs. PerAF) have been previously studied and assessed via statistical tests in order to suggest optimized approaches to catheter ablation (CA) of AF

MOTOR UNIT SYNCHRONIZATION AT DIFFERENT INTENSITIES OF MUSCLE CONTRACTION AS REVEALED BY DETERMINISM OF SURFACE MYOELECTRIC SIGNAL

Autor: Sergeeva, X.V., Tambovtseva, R.V.

For the first time using Recurrence quantification analysis (RQA) of the surface EMG data we conducted an indirect assessment of motor unit (MU) synchronization of the quadriceps muscle in eccentric and concentric modes of contraction during leg exte

Eccentric exercise induces spatial changes in the mechanomyographic activity of the upper trapezius muscle

Autor: Dariusz Mroczek, Adam Kawczyński, Afshin Samani, Ernst Albin Hansen, Martyna Kumorek, Rasmus Elbæk Andersen, Pascal Madeleine

Publikováno v: Madeleine, P, Hansen, E A, Andersen, R E, Kumorek, M, Mroczek, D, Samani, A & Kawczyński, A 2018, ' Eccentric exercise induces spatial changes in the mechanomyographic activity of the upper trapezius muscle ', Scandinavian Journal of Medicine and Science in Sports, vol. 28, no. 6, pp. 1661-1670 . https://doi.org/10.1111/sms.13067

In this study, we hypothesized that the recordings of multichannel mechanomyography (MMG) of the upper trapezius muscle would reveal spatially dependent manifestations in the presence of delayed onset muscle soreness occurring 24 hours after eccentri
