Effect of the Kinesio tape to muscle activity and vertical jump performance in healthy inactive people
Source, 5 hours ago
Background: Elastic taping applied on the triceps surae has been commonly used to improve the performance of lower extremities. However, little objective evidence has been documented. The purpose of this study was to investigate the effect of elastic taping on the triceps surae during a maximal vert...
Evaluation of the effect of stent strut profile on shear stress distribution using statistical moments
Source, 5 hours ago
Background: In-stent restenosis rates have been closely linked to the wall shear stress distribution within a stented arterial segment, which in turn is a function of stent design. Unfortunately, evaluation of hemodynamic performance can only be evaluated with long term clinical trials. In this work...
Home-based system for physical activity monitoring in patients with multiple sclerosis (Pilot study)
Source, 5 hours ago
Background: Limitations in physical activity are considered as a key problem in patients with multiple sclerosis (PwMS). Contemporary methods to assess the level of physical activity in PwMS are regular clinical observation. However, these methods either rely on high recall and accurate reporting fr...
Biological effects of exposure to magnetic resonance imaging: an overview
Source, 5 hours ago
The literature on biological effects of magnetic and electromagnetic fields commonly utilized in magnetic resonance imaging systems is surveyed here. After an introduction on the basic principles of magnetic resonance imaging and the electric and magnetic properties of biological tissues, the basic ...
Oscillometric measurement of systolic and diastolic blood pressures validated in a physiologic mathematical model
Source, 5 hours ago
Background: The oscillometric method of measuring blood pressure with an automated cuff yields valid estimates of mean pressure but questionable estimates of systolic and diastolic pressures. Existing algorithms are sensitive to differences in pulse pressure and artery stiffness. Some are closely gu...
Performance of the Emotiv Epoc headset for P300-based applications
Source, 5 hours ago
Background: For two decades, EEG-based Brain-Computer Interface (BCI) systems have been widely studied in research labs. Now, researchers want to consider out-of-the-lab applications and make this technology available to everybody. However, medical-grade EEG recording devices are still much too expe...
How smartphones are changing the face of mobile and participatory healthcare: an overview, with example from eCAALYX
Source, 5 hours ago
The latest generation of smartphones are increasingly viewed as handheld computers rather than as phones, due to their powerful on-board computing capability, capacious memories, large screens and open operating systems that encourage application development. This paper provides a brief state-of-the...
Challenges, issues and trends in fall detection systems
Source, 5 hours ago
Since falls are a major public health problem among older people, the number of systems aimed at detecting them has increased dramatically over recent years. This work presents an extensive literature review of fall detection systems, including comparisons among various kinds of studies. It aims to ...
Heart monitoring using left ventricle impedance and ventricular electrocardiography in left ventricular assist device patients
Source, April 17, 2015
Background: Patients who develop critical arrhythmia during left ventricular assist device (LVAD) perfusion have a low survival rate. For diagnosis of unexpected heart abnormalities, new heart-monitoring methods are required for patients supported by LVAD perfusion. Ventricular electrocardiography u...
Experimental evaluation and computational modeling of the effects of encapsulation on the time-profile of glucose-stimulated insulin release of pancreatic islet...
Source, April 17, 2015
Background: In type 1 diabetic patients, who have lost their ability to produce insulin, transplantation of pancreatic islet cells can normalize metabolic control in a manner that is not achievable with exogenous insulin. To be successful, this procedure has to address the problems caused by the imm...
