BACKGROUND Stress is a risk factor for musculoskeletal pain. We wanted to explore stress related physiology in healthy subjects in order to gain insight into mechanisms of pain development which may relate to the pathophysiology of musculoskeletal pain disorders. METHODS Continuous blood pressure, heart rate, finger skin blood flow, respiration, surface electromyography together with percepti...

The innovative non-invasive intracranial volume wave monitor has been developed in Telematics Scientific Laboratory of Kaunas University of Technology (Lithuania). It is based on the measurement of the human brain parenchyma acoustic properties (ultrasound speed and attenuation) using time-of-flight technique [1,2] and it is capable of measuring different types of intracranial volume wave (slow...

BACKGROUND Continuous non-invasive measurement of finger arterial pressure (FAP) is a reliable technology in adults. FAP is measured with an inflatable cuff around the finger and simultaneously converted to a reconstructed brachial artery pressure waveform (reBAP) by the Nexfin™ device. We assessed the adequacy of a prototype device (Nexfin-paediatric), designed for a paediatric population, for...

Blood pressure measurement methods used nowadays have considerable drawbacks, as non-invasive measurements are non-continuous while invasive measurements are confined to in-hospital use. In this paper, we expose our solution of a continuous, non-invasive blood pressure measurement method, using electrocardiogram (ECG) and photopletysmograph (PPG) as a basis of calculation. We present the two ap...

1. The magnitude and time course of circulatory adaptation to active standing were investigated in healthy premenarchic girls and boys (n = 24; 10-14 years old) by non-invasive measurement of heart rate and continuous finger blood pressure (Finapres). 2. Four subjects (two girls, two boys) showed presyncopal symptoms after 4-9 min of free standing. 3. In the 20 non-fainting subjects, changes in...
