EFFICACY OF LASER PULSE FREQUENCIES ON BLOOD FLOW IN TYPE 2 DIABETIC PATIENTS

International Journal of Physiotherapy, 2017
Background: Research reports had noted an apparent increase in cutaneous and deep blood flow as a result of low-intensity laser therapy (LLLT) in normal subjects.

Novel application of a force sensor during sit‐to‐stands to measure dynamic cerebral autoregulation onset

Physiological Reports, 2022
Current sit‐to‐stand methods measuring dynamic cerebral autoregulation (dCA) do not capture the precise onset of the time delay (TD) response. Reduced sit‐to‐stand reactions in older adults and individuals post‐stroke could inadvertently introduce ...

Cerebral blood flow velocity is associated with endothelial function in men [PDF]

Journal of Men's Health, 2021
Background and objective: Reduction in cerebral blood flow with aging leads to cognitive decline and brain atrophy. Cerebrovascular hemodynamics are associated with vascular function.

Hidden fluid mechanics: Learning velocity and pressure fields from flow visualizations

Science, 2020
Machine-learning fluid flow Quantifying fluid flow is relevant to disciplines ranging from geophysics to medicine. Flow can be experimentally visualized using, for example, smoke or contrast agents, but extracting velocity and pressure fields from this ...

Assessment of blood flow velocity and pulsatility in cerebral perforating arteries with 7‐T quantitative flow MRI

NMR in Biomedicine, 2015
Thus far, blood flow velocity measurements with MRI have only been feasible in large cerebral blood vessels. High‐field‐strength MRI may now permit velocity measurements in much smaller arteries.

Revealing Intraosseous Blood Flow in the Human Tibia With Ultrasound

JBMR Plus, 2021
Intraosseous blood circulation is thought to have a critical role in bone growth and remodeling, fracture healing, and bone disorders. However, it is rarely considered in clinical practice because of the absence of a suitable noninvasive in vivo ...

Characterization of retinal microvasculature in acute non-arteritic anterior ischemic optic neuropathy using the retinal functional imager: a prospective case series

Eye and Vision, 2019
Background Non-arteritic anterior ischemic optic neuropathy (NAION) is the most common cause of acute optic neuropathy in patients over 50 years of age, and many affected individuals are left with permanent visual deficits. Despite the frequency of NAION

Measurement of the blood flow rate and velocity in coronary artery stenosis using intracoronary frequency domain optical coherence tomography: Validation against fractional flow reserve

International Journal of Cardiology: Heart & Vasculature, 2014
Objectives: The main objective of this study was to assess the blood flow rate and velocity in coronary artery stenosis using intracoronary frequency domain optical coherence tomography (FD-OCT). A correlation between fractional flow reserve (FFR) and FD-

Blood flow velocity quantification using split-spectrum amplitude-decorrelation angiography with optical coherence tomography.

Biomedical Optics Express, 2013
The split-spectrum amplitude-decorrelation angiography (SSADA) algorithm was recently developed as a method for imaging blood flow in the human retina without the use of phase information.

Aerobic exercise training increases cerebral blood flow in postmenopausal women

Artery Research, 2012
Background: Age-related decrease in cerebral blood flow is a risk factor for cognitive decline. Aerobic exercise training improves vascular and cognitive functions.
