The effect of pain on task switching: pain reduces accuracy and increases reaction times across multiple switching paradigms

We present 3 studies to test this hypothesis. In study 1, participants completed 2 versions of an alternating runs switching task under pain-free and thermal pain–induction conditions. Pain did not affect performance on either task. In studies 2 and 3, we examined 7 versions of the switching task using large general population samples, experiencing a variety of naturally occurring pain conditions, recruited and tested on the internet. On all tasks, participants with pain had longer reaction times on both switch and repeat trials compared with participants without pain, but pain did not increase switch costs. In studies 2 and 3, we also investigated the effects of type of pain, duration of pain, and analgesics on task performance. We conclude that pain has a small dampening effect on performance overall on switching tasks. This suggests that pain interrupts attention even when participants are engaged in a trial, not only when attention has been disengaged for shifting to a new task set.

This study is an attempt to investigate the effects of intrathecal administration of Melissa officinalis on the pain induced by heat and formalin.In this experimental study, seventy male Wistar rats with an average weight of 270-320 g were randomly divided into 5 groups: control; sham, that received 25 μl of saline through the spinal catheter; and three experimental groups, that received 5, 10 or 20 mg/kg Melissa officinalis via the spinal catheter respectively. Five days after catheterization of the spinal cord from the lumbar region under anesthesia, the effects of Intrathecal administration of Melissa officinalis on ...

Conclusions: Similar to previous studies, our results suggest that patients suffering from CLBP differ with regard to the magnitude of mental burden and the presence of physical impairment. These differences ascertain the need for precise targeting of treatment for CLBP. Inpatient pain centers therefore should offer different multimodal therapy pathways and integrate a meaningful triage, taking into account the multifaceted nature of CLBP based on sophisticated knowledge about forms, differences, and relationships among the biopsychosocial components of CLBP.

CONCLUSION: The etiology of chronic groin pain post hernia repair is related in part to nerve injury. This is supported by the high frequency of sensory symptoms and numbness in these patients. However other factors including the role of tissue injury and inflammatory postoperative changes need to be considered.

Many people struggle with chronic boredom. But what exactly is boredom and what are some ways to move beyond it? According to Wikipedia, “Boredom is an emotional and occasionally psychological state experienced when an individual is left without anything in particular to do, is not interested in their surroundings, or feels that a day or period is dull or tedious.” We all know the feeling. It is part of life. But sometimes it’s a symptom of something deeper that needs tending. In my psychotherapy practice, I see a few main causes for chronic states of boredom:  Boredom which functions...

It generates chronic instability, leading to osteoarthritis. It may be associated with fracture of the distal epiphysis of the radius or of the scaphoid. These lesions are often difficult to diagnose, especially in early stages. Treatment of chronic scapholunate ligament lesions before onset of osteoarthritis is a challenge for the sur...
