Painful view on motor actions

Jaakko Hotta

Imagine you sprained your wrist. It’s aching, swollen and reddish. You want to move the hand to see if it is ok, but the fear of pain makes you hesitate and it takes extra effort to do it. Even thinking about movement can be unpleasant and you focus on doing things with the healthy hand. After days and weeks, as the trauma heals, the pain passes … [Read more...]

tDCS – the bigger picture

Last year I told you about a trial where we compared the brain’s activity during pain processing in the fMRI scanner before or after the application of an electrical brain stimulation technique (transcranial direct current stimulation (tDCS)). The result was that there wasn’t much change after tDCS, hence we raised doubts that tDCS had an effect on … [Read more...]

Isometrics reduce tendon pain

Ebonie Kendra Rio

Anyone with tendon pain will tell you, it’s a pain in the butt (hamstring tendon pain that is). If it’s your Achilles tendon, the mornings are a struggle and you may have stopped walking, running or playing with your kids. For the athlete, pain relating to the Achilles, Patellar, Hamstring or Adductor tendons can strip away power and spring needed … [Read more...]

Brain Image Biomarkers for Pain: Why should we?

BodyInMind

Indulge me for a moment. Let’s say you just arrived at your physician’s office with a troubling symptom. She says “Hold on, I need to put you in the MRI to see if this symptom is pain, or if you are a pain patient.” There have been a number of scientific papers and popular press releases that suggest we need to replace self-report of pain … [Read more...]

How does sensory and sympathetic nerve sprouting contribute to a chronic pain state in a nonhealed fracture?

Stephane Chartier

Our lab continues to be intrigued by the mechanisms that generate and drive skeletal pain. Painful skeletal conditions are highly prevalent and their impact is pervasive in both developing and developed countries (Lubeck, 2003;Woolf & Pfleger, 2003; Brooks, 2006; Kidd, 2006). The skeletal system is essential for structural support, movement, … [Read more...]

Leprosy and Pain: an Old Disease with a New Challenge

Felipe Reis

Perhaps you have already heard about leprosy in the past. Despite major efforts to eradicate leprosy, this infection still affects 250,000 new individuals per year [1]. The mode of transmission of leprosy is probably person to person through nasal secretions from untreated patients. The disease is well known because of the biblical stories and it … [Read more...]

Core outcome domains for non-specific low back pain

Alessandro Chiarotto

In 1997, during the second International Forum on Primary Care Research for Low Back Pain (LBP) held in The Hague (Netherlands), a group of experienced clinical researchers gathered together and decided to formulate a standardised set of outcomes to be recommended to colleagues for use in LBP clinical research. These recommendations included five … [Read more...]

Self-management for people with back pain and osteoarthritis – reviewing the evidence

Elaine Toomey

Osteoarthritis (OA) and chronic low back pain (CLBP) are two of the most common musculoskeletal pain conditions in the developed world (WHO, 2003). These conditions place a huge burden on both the health system, in terms of service demand, and the people with the condition, in terms of quality of life and personal wellbeing (Buchbinder et al., … [Read more...]

50 shades of touch: the relationship between pleasure and pain

Dr Alberto Gallace

Pain is usually such a negative experience that we rarely think about it in terms of just another sensory modality let alone consider the potential of positive aspects to it. Because of that, this post will be a bit unconventional, especially for a BiM blog. My post, somehow inspired by the controversial novel and movie, “50 shades of Grey”, is … [Read more...]

Sleep, pain and exercise

Helena Hachul

Sleep is an essential biological phenomenon, and sleep deprivation causes various physiologic and behavioral changes in the body. It has been shown that total sleep deprivation (Shuch-Hofer et al., 2013) or sleep deprivation of a specific stage of sleep (Roehrs et a., 2006; Azevedo et al., 2011) cause hyperalgesia (exaggerated sensitivity to pain). … [Read more...]
