Capturing and sharing the voice and experiences of those who are living with Complex Regional Pain Syndrome

Karen Rodham

Complex Regional Pain Syndrome (CRPS) is difficult to diagnose and is characterised by burning pain in one or more limbs, with 15-20% of patients developing long term disability [1]. The cause is unknown and there is currently no cure. As a consequence, people living with CRPS often turn to the Internet to seek CRPS-related information and support … [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...]

Capillary dysfunction in CRPS?

Leif ostergaard

Reports suggest that muscles lack oxygen and skin oxygenation is impaired in Complex Regional Pain Syndrome (CRPS). While CRPS might be related to tissue ischemia-reperfusion, the affected limb is often hyperperfused, suggesting that oxygen extraction is severely impaired instead. In a recent paper in Pain, we speculate that capillary flow … [Read more...]

World Congress on Pain comes to you. 1: Disentangling CRPS

Adios Buenos Aires, IASP World Congress is always such a big beast. Vast conference halls, so many possible sessions to attend, so many posters to view and in this case so many fantastic Argentinian steaks to eat and wash down with equally fantastic Malbec. But you often leave trying to make sense of what you have heard and what, if anything, … [Read more...]

New light on bone formation in CRPS?

Roberto_Perez

The variability of signs and symptoms of Complex Regional Pain Syndrome (CRPS), may represent between-patient variability in the pathological mechanisms at work. One often forgotten CRPS feature is impaired bone formation yet this has been found in up to fifty percent of patients regardless of disease duration [1]. German Surgeon Paul Sudeck … [Read more...]

A tool for communicating body perception disturbances

Ailie Turton

Some people with persistent pain have altered perceptions of parts of their body. For example they can perceive their affected limbs as having some distortions of size, perhaps with enlarged hands or very thin forearms. They can also feel that the limb is in a different position to its actual location and that areas of body or limb segments are … [Read more...]

Do People Recover from CRPS?

Debbie Bean

Complex Regional Pain Syndrome (CRPS) is a condition which can invoke fear and dread both in patients and healthcare providers.  Many patients I’ve met who have been told they’ve got CRPS have done a little searching on Dr Google and come away terrified, thinking CRPS is a life sentence, worrying it might never get any better, having read that … [Read more...]

Motor dysfunction in Complex Regional Pain Syndrome is related to proprioceptive deficits

Imagine that you want to grab a cup of coffee. Successful planning and execution of this and many other everyday life tasks crucially depends on a good sense of the position and movements of your body parts (= proprioception). Such tasks would be very difficult to perform if you have no (or perhaps the wrong) idea of where your hand is, or what it … [Read more...]

Preserved ability to integrate a rubber hand indicates intact multisensory integration in CRPS

Annika Reinersmann

To the avid BiM reader the Rubber Hand Illusion (RHI) is probably well-known and old hat (for the not-so avid reader see below*). It is a popular paradigm because it can be used to investigate a) functionality of multisensory integration in corresponding brain areas and b) pre-existing mental representations of the body, i.e. body image [1]. We … [Read more...]

Can pain change our brain maps?

We recently published a paper on the function of the primary somatosensory cortex in Complex Regional Pain Syndrome (CRPS). The primary somatosensory cortex (S1) is a region of the cortex –the outer layer of the brain –which houses a precise and organised map of our body’s surface. Every part of our body surface is represented here by a network or … [Read more...]
