background and purpose: pain perception with arteriovenous fistula (avf) cannulation is a major concern among patients undergoing hemodialysis. this study aimed to compare the efficacy of cryotherapy and placebo in the reduction of avf puncture-related pain in hemodialysis patients. methods: this randomized clinical trial was conducted on 50 patients undergoing hemodialysis selected via random ...

BACKGROUND The eight-item Brief Illness Perception Questionnaire is used as a screening instrument in physical therapy to assess mental defeat in patients with acute low back pain, besides patient perception might determine the course and risk for chronic low back pain. However, the psychometric properties of the Brief Illness Perception Questionnaire in common musculoskeletal disorders like ac...

The pain perception of 30 competitive swimmers was studied using experimentally induced ischaemic pain. The pain thresholds and tolerances of this group were compared with those of 30 club swimmers and 26 non-competitive athletes. While pain thresholds showed little difference between the groups, pain tolerances were considerably different. Pain tolerances of the competitive swimmers varied acc...

The placebo effect is a component of any response to a treatment (effective or inert), but we still ignore why it exists. We propose that placebo analgesia is a facet of pain perception, others being the modulating effects of emotions, cognition and past experience, and we suggest that a computational understanding of pain may provide a unifying explanation of these phenomena. Here we show how ...

Pain is emotionally detrimental and consciously avoided; however, it is absolutely crucial for our survival. Pain perception is one of the most complicated measurable traits because it is an aggregate of several phenotypes associated with peripheral and central nervous system dynamics, stress responsiveness and inflammatory state. As a complex trait, it is expected to have a polygenic nature sh...

PURPOSE The primary objective of the present study was to evaluate predictive parameters of the acute pain score during induction of an inflammatory heat injury. PATIENTS AND METHODS Healthy volunteers (50 females/50 males) were included in the study. The predictive potential of gender, anthropometric (body surface area, body mass index), psychological (anxiety, depression, vulnerability), an...

Alongside the time-locked event-related potentials (ERPs), nociceptive somatosensory inputs can induce modulations of ongoing oscillations, appeared as event-related synchronization or desynchronization (ERS/ERD) in different frequency bands. These ERD/ERS activities are suggested to reflect various aspects of pain perception, including the representation, encoding, assessment, and integration ...

PURPOSE & FIELD More than one hundred million people around the world undergo a surgery annually. Although, the surgery itself is a treatment method to relieve pain and discomfort, it can be considered as one of the important factors to make a pain too. Perception and diagnosis of the pain is the most important duty of nurses. Effective pain management after surgery facilitates the patient's re...
