UNLABELLED Neonatal pain experiences have been associated with altered processing and perception of pain in later life, but findings tend to vary among studies. We have compared experimental pain tolerance and subjective health complaints in a population-based cohort of adolescents born extremely preterm to that of matched term controls. Subjects performed a standardized cold pressor task (hand...

BACKGROUND Obesity is a global epidemic with important health care and financial implications. The cold pressor test (CPT) which is considered to be a sympathy-excitatory manoeuvre is a simple, noninvasive and validated test. The objective of this study was to assess and compare the cardiovascular response to cold pressor test in non-obese and obese healthy adults. METHODS The study included ...

The purpose of this study was to examine pain perception during and following two separate 30-min bouts of exercise above and below the Lactate Threshold (LT). Pain Threshold (PT) and Pain Intensity (PI) were monitored during (15 and 30 min) and after exercise (15 and 30 min into recovery) using a Cold Pressor Test (CPT) and Visual Analog Scale (VAS) for pain of the non-dominant hand. Significa...

Pain tolerance can be increased by the introduction of an active distraction, such as a computer game. This effect has been found to moderated game demand, i.e., demand = higher pain tolerance. A study was performed classify level and presence using implicit measures from functional Near-InfraRed Spectroscopy (fNIRS) heart rate features electrocardiogram (ECG). Twenty participants played racing...

Although a common pain response, whether swearing alters individuals' experience of pain has not been investigated. This study investigated whether swearing affects cold-pressor pain tolerance (the ability to withstand immersing the hand in icy water), pain perception and heart rate. In a repeated measures design, pain outcomes were assessed in participants asked to repeat a swear word versus a...

BACKGROUND Photoplethysmographic pulse wave amplitude (PPGA) and heart rate (HR) can be used to measure cold, nociception-induced autonomic responses, or both. The aim of our study was to correlate the intensity of experimental pain to changes in physiological variables reflecting the autonomic nervous system response to pain. METHODS PPGA, HR, and subjective measurements of pain intensity we...

OBJECTIVE We tested the hypothesis that muscle sympathetic nerve activity (MSNA) and forearm vascular resistance (FVR) would be augmented during mental stress or cold pressor test in healthy obese individuals compared with healthy lean individuals. RESEARCH METHODS AND PROCEDURES Twenty-nine healthy obese women and 12 age-matched healthy lean women were involved in the study. MSNA was directl...
