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...]

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...]

tDCS for clinical use. Let’s not throw the baby out with the bath water

Asbjørn Fagerlund

In my academically formative years, a psychology text book defined psychology as a scientific discipline that aims to describe, predict and change behavior. This definition stuck. Shortly afterwards, during my training as a clinical psychologist, I was introduced to tDCS by Dr. Per Aslaksen at the University of Tromsø. The method was appealing: a … [Read more...]

Sympathetic blocks for complex regional pain syndrome

Based largely on his clinical experience, the founding father of modern pain medicine, John J. Bonica, recommended that complex regional pain syndrome (CRPS) be treated with a series of sympathetic blocks as soon as possible after symptoms develop. Although this sometimes seems to work well, the value of this approach has been questioned because of … [Read more...]

Which treatments are people with osteoarthritis actually using?

Kim Bennell

It has been well established that hip and knee osteoarthritis (OA) is one of the major causes of disease burden worldwide. There is currently no cure and joint replacement is typically reserved for advanced disease, whilst arthroscopy has been shown to have little or no benefit. For over 10 years now there has been substantial evidence supporting … [Read more...]

When I feel your pain

Sophie Vandenbroucke

Imagine you are preparing food with your partner. Suddenly, you observe your better half accidently cutting his or her hand with a kitchen knife. You may feel uncomfortable and distressed. In fact, you might even respond as though your hand has been cut – by experiencing the pain that would be associated with that event. This phenomenon, referred … [Read more...]

The role of significant others in the management of persistent musculoskeletal pain

Serena McCluskey

It has long been acknowledged that persistent musculoskeletal pain can be influenced by environmental factors, with an important source being the interaction between the pain sufferer and their ‘significant other’ (spouse/partner/relative). It is proposed that significant others can reinforce an individual’s unhelpful pain cognitions, such as fear … [Read more...]

World congress comes to you 7: Yes we can (control chronic pain)

In reviewing the notes I took during the workshop “Beyond the ordinary: Innovative psychological and educational approaches to chronic pain treatment” (15th World Congress on Pain, Buenos Aires), one important message stands out: pain is an experience produced by our brain and, for this reason, we can control it. How? During this workshop three … [Read more...]

Classification of low back pain. Are we winning?

Martin Rabey

As clinicians we know that no two people with low back pain (LBP) are identical. However, if we looked at a large number of people with LBP, would we be able to see some patterns emerge? Or similarities that could allow us to group these people together based upon some characteristics of their presentations? The idea of classification systems for … [Read more...]

Sensory conflicts may increase limb pain in CRPS by activating mechanisms of general facilitation of nociception

Lone Knudsen

I continue to be fascinated by the perplexing symptoms of complex regional pain syndrome (CRPS). CRPS is characterised by the changeable nature of symptoms throughout the day and during the course of the disease, and patients with CRPS often perceive the affected limb as larger than its actual size (Moseley, 2005; Peltz et al., 2011). Patients with … [Read more...]
