Increased cortical activation upon painful stimulation in fibromyalgia syndrome
BACKGROUND Fibromyalgia syndrome (FMS) is a chronic condition characterized by widespread pain and associated symptoms. We investigated cerebral activation in FMS patients by functional near-infrared spectroscopy (fNIRS). METHODS Two stimulation paradigms were applied: a) painful pressure stimulation at the dorsal forearm; b) verbal fluency test (VFT). We prospectively recruited 25 FMS patien...
متن کاملDifferential Effects of Painful and Non-Painful Stimulation on Tactile Processing in Fibromyalgia Syndrome and Subjects with Masochistic Behaviour
BACKGROUND In healthy subjects repeated tactile stimulation in a conditioning test stimulation paradigm yields attenuation of primary (S1) and secondary (S2) somatosensory cortical activation, whereas a preceding painful stimulus results in facilitation. METHODOLOGY/PRINCIPAL FINDINGS Since previous data suggest that cognitive processes might affect somatosensory processing in S1, the present...
متن کاملSex differences in responsiveness to painful and non-painful stimuli are dependent upon the stimulation method.
Sex differences in thermo- and electrocutaneous responsiveness to painful and non-painful stimuli were investigated in 20 women and 20 men. Heat pain, warmth, and cold thresholds were assessed on the hand and foot with a Peltier thermode system. In addition, subjects used magnitude estimation to judge the sensation intensity evoked by temperatures ranging from 38 degrees C to 48 degrees C appli...
متن کاملCortical activation by tactile and painful stimuli in hemispherectomized patients.
Hemispherectomized patients are able to perceive tactile and painful stimuli on their nonparetic as well as paretic body halves. We have used functional MRI to study the cortical mechanisms underlying this preserved somatosensory capacity. Nonpainful brushing and painful heat were applied to the skin of the legs in four hemispherectomized patients and, for comparison, in four normal subjects. C...
متن کاملIncreased bladder permeability in interstitial cystitis/painful bladder syndrome
The definition of interstitial cystitis (IC) has evolved over the years from being a well-defined entity characterized by diagnostic lesion (Hunner's ulcer) in the urothelium to a clinical diagnosis by exclusion (painful bladder syndrome (PBS). Although the etiology is unknown, a central theme has been an association with increased permeability of the bladder. This article reviews the evidence ...
