A portable device for quantitative measurement of tissue autoregulation and neurovascular coupling via portable measurement of blood flow, oxygenation, metabolism, and/or EEG signals and methods for using said device. The device may comprise a body and a plurality of legs pivotably attached to the body. The plurality of legs may comprise at least one reference electrode leg and at least one measurement electrode leg for electrical measurement, and an optical detection fiber leg and at least one optical source fiber leg for optical blood flow, oxygenation, and metabolism measurement. The present invention is additionally directed to a portable device for blood flow measurement and therapeutic photobiomodulation. The device may comprise a body and a plurality of legs. The plurality of legs may comprise at least one optical detection fiber leg and at least one optical source fiber leg, and at least one leg for therapeutic photobiomodulation.

The technology relates to medical devices for monitoring and assessing vascular health. In one embodiment, the technology is an apparatus that attaches to a subject's finger comprising a heating and cooling component, a coherent source, a temperature sensor, an image detector, and/or a component for data control and management. In another embodiment, there is a component that alters local blood flow in the subject, and laser speckle contrast and photoplethysmography (PPG) signals from the altered blood flow in the subject are compared to monitor the vascular health of the subject.
