Assessing cardiovascular risks from a mid-thigh CT image: A tree-based machine learning approach using radiodensitometric distributions

Ricciardi, Carlo; Edmunds, Kyle; Recenti, Marco; Sigurdsson, Sigurdur; Gudnason, Vilmundur; Carraro, Ugo; Gargiulo, Paolo (Springer Science and Business Media LLC, 2020-02-18)

The nonlinear trimodal regression analysis (NTRA) method based on radiodensitometric CT distributions was recently developed and assessed for the quantification of lower extremity function and nutritional parameters in aging subjects. However, the use ...
Effects of sustained electrical stimulation on spasticity assessed by the pendulum test

Vargas Luna, José Luis; Halla Kristín Guðfinnsdóttir; Gígja Magnúsdóttir; Vilborg Guðmundsdóttir; Krenn, Matthias; Mayr, Winfried; Guðbjörg Kristín Ludvigsdóttir; Þórður Helgason (Walter de Gruyter GmbH, 2016-09-30)

Neuromodulation using electrical stimulation is able to enhance motor control of individuals suffering an upper motor neuron disorder. This work examined the effect of sustained electrical stimulation to modify spasticity in the leg muscles. We applied ...
Nonlinear Trimodal Regression Analysis of Radiodensitometric Distributions to Quantify Sarcopenic and Sequelae Muscle Degeneration

Edmunds, Kyle; Árnadóttir, Íris Dröfn; Gíslason, Magnús; Carraro, Ugo; Gargiulo, Paolo (Hindawi Limited, 2016-12)

Muscle degeneration has been consistently identified as an independent risk factor for high mortality in both aging populations and individuals suffering from neuromuscular pathology or injury. While there is much extant literature on its quantification ...
Preferential activation of small cutaneous fibers through small pin electrode also depends on the shape of a long duration electrical current

Hugosdottir, Rosa; Mørch, Carsten Dahl; Andersen, Ole Kæseler; Helgason, Thordur; Arendt-Nielsen, Lars (Springer Science and Business Media LLC, 2019-09-14)

Background Electrical stimulation is widely used in experimental pain research but it lacks selectivity towards small nociceptive fibers. When using standard surface patch electrodes and rectangular pulses, large fibers are activated at a lower threshold ...
