OBJECTIVE The perception of pain is susceptible to modulation by psychological and contextual factors. It has been shown that subjects judge noxious stimuli as more painful in a respective suggestive context, which disappears when the modifying context is resolved. However, a context in which subjects judge the painfulness of a nociceptive stimulus in exactly the opposite direction to that of t...

[Purpose] This study investigated the changes in pressure pain threshold of the upper trapezius, levator scapular, and rhomboid muscles during continuous computer work. [Subjects] Fourteen males and females aged 26-32 years, were recruited. [Methods] A dolorimeter pressure algometer was used to measure the pressure pain threshold of the upper trapezius, levator scapular, and rhomboid muscles, r...

OBJECTIVE Decreased pain sensitivity is found in individuals who are ill with bulimia nervosa (BN). The purpose of this study is to determine whether altered pain perception persists after recovery from bulimia nervosa (RBN). METHODS Eleven women who were recovered from BN for more than 1 year were compared with 15 healthy volunteer women. The participants received two pain evaluations--therm...

[Purpose] It has also been reported that decreased activity in the reward pathway causes a decrease in brain activity in the descending pain control system in people with high trait anxiety. Activation of this system is dependent on both the reward pathway and motor areas. Recently, studies have also shown that motor areas are activated by illusory kinesthesia. It was aimed to explore whether a...

Aim and Introduction: It is often assumed that persons with visual impairment have a better sensory perception this ability helps them to perceive the environment better. To objectively study this assumption we carried out a study on sensory, pain thresholds and pain tolerance in persons with visual impairment. Materials and Methods: An electrodiagnostic stimulator was used to assess the sensor...

background: diabetes mellitus is the most common metabolic disorder with many complications such as neuropathic pain which relief from it is a dilemma. objectives: to investigate the effect of hydroethanolic extract of rubus fruticosus on neuropathic pain in diabetic rats. materials and methods: in this experimental case –control study, forty eight male wistar rats (250±20 g) were divided rando...

OBJECTIVE Mixed evidence exists regarding whether irritable bowel syndrome (IBS) patients show increased somatic pain perception compared with controls. The current study used a deep, tonic somatic pain stimulus (ischemic pain) to evaluate somatic hypersensitivity in IBS patients. METHODS A total of 27 diarrhea-predominant and 15 constipation-predominant IBS patients, and 29 controls particip...

Genetic basis of pain sensation became one of the hot topics in pain medicine over the past several years. Although numerous studies have suggested the existence of the genetic component of pain threshold, majority of these findings were based on a candidate-gene approach and remained un-replicated, and thus of limited importance [1]. Commonly used approach to investigate genetic basis of any t...

BACKGROUND Arthroscopic shoulder surgery is increasingly performed as a day case procedure. Optimal post-operative pain relief remains a challenge due to considerable variations in the level of pain experienced between individuals. Our aim was to examine whether the preoperative electrical pain threshold was a strong predictor of elevated postoperative pain levels following arthroscopic subacro...
