Laser Doppler Flowmetry in Manual Medicine Research

Journal of Osteopathic Medicine, 2014
Abstract Laser Doppler flowmetry (LDF) is commonly used in combination with reactivity tests to noninvasively evaluate skin sympathetic nerve activity and skin microvascular function. In manual medicine research, LDF has been used as a marker for global peripheral sympathetic nervous system function, but these results ...

Quantifying skin microvascular function responses to distinct forms of heat stress in humans using optical coherence tomography

Experimental Physiology, EarlyView.
Abstract Optical coherence tomography (OCT) enables visualization and quantification of the cutaneous microvasculature, yet no study has compared responses to distinct forms of heating in humans. We hypothesized that local skin heating (LH) would evoke larger responses in microvascular diameter, velocity, flow and density than passive whole‐body ...

Passive heat therapy is feasible but does not affect cardiometabolic health outcomes in persons with spinal cord injury – a pilot study

Experimental Physiology, EarlyView.
Abstract Passive heat therapy can improve cardiometabolic health outcomes in some clinical populations, making it a potential therapeutic tool for individuals with spinal cord injury (SCI), who exhibit elevated cardiometabolic disease risk and face barriers to physical activity.

Pressure‐dependent coupling between arterial pressure and intercostal muscle blood‐flow index during acute hypotension in humans

Experimental Physiology, EarlyView.
Abstract Regulation of respiratory muscle blood flow during acute systemic hypotension remains poorly understood in humans because continuous assessment of microvascular perfusion during rapid haemodynamic transients has been technically challenging. Using diffuse correlation spectroscopy, we investigated second‐by‐second coupling between mean arterial

Laser Doppler Flowmetry as a method of analysis for the evaluation of chemo - induced oral mucositis: A pilot study.

Journal of Oral Research, 2020
Background: Oral mucositis (OM) is an inflammation of the oral mucosa due to cancer therapy that compromises the patient’s quality of life. Laser Doppler flowmetry (LDF) is a non-invasive method to monitor microvascular blood flow (BF) in real-time ...

Perfusion assessment in rat spinal cord tissue using photoplethysmography and laser Doppler flux measurements [PDF]

, 2013
Animal models are widely used to investigate the pathological mechanisms of spinal cord injury (SCI), most commonly in rats. It is well known that compromised blood flow caused by mechanical disruption of the vasculature can produce irreversible damage ...
