Severe STRESS reduces the BRAIN’s capacity to control PAIN   January 1st, 2014
Stress is often a powerful pain killer. Stress activates several brain-orchestrated pain inhibitory actions, including the activation of the hypothalamus-pituitary-adrenal axis (HPA-axis) resulting in the release of cortisol. The latter is often regarded as the major stress hormone in the human body, and besides its powerful anti-inflammatory action it also exerts endogenous analgesia.

Does central sensitization play a role in chronic tendinopathy?   January 1st, 2014
The prevalence of tendinopathies is high both in athletes and in the general population. Despite a wealth of literature, the pain mechanisms of tendinopathies are not well understood. Currently, some studies have described whether, or to which degree, somatosensory changes within the nervous system may contribute to the pain in tendinopathies.

Why does my shoulder hurt?   January 1st, 2014
Dean et al. recently reviewed the neuroanatomical and biochemical basis of shoulder pain. Shoulder pain is often a very challenging clinical phenomenon because of the potential mismatch between pathology and the perception of pain. As shoulder pain is very common in the physiotherapeutic clinical practice, a vast understanding of pain processing could enlarge the specificity of the patients’ diagnosis and steer treatment.

Exercise therapy for rewriting pain memories? Applying graded exposure in vivo principles during exercise therapy for targeting the brain circuitries orchestrated by the amygdala   January 1st, 2014
Even though nociceptive pathology has often long subsided, the brain of patients with chronic musculoskeletal pain has typically acquired a protective (movement-related) pain memory. Exercise therapy for patients with chronic musculoskeletal pain is often hampered by such pain memories.

Not in the mind, but in the immune system! Altered immune response to exercise in patients with chronic fatigue syndrome/myalgic encephalomyelitis   January 1st, 2014
Chronic Fatigue Syndrome (CFS), or myalgic encephalomyeltitis (ME), is a severe and underestimated illness. The presence of symptoms like a sore throat, tender lymph nodes, and low-grade fever, as well as flu-like symptoms including widespread muscle pain and severe fatigue, has inspired researchers to search for immune abnormalities in patients with ME/CFS.

Pain increases during walking in osteoarthritis related to central sensitization   January 1st, 2014
The April issue of Pain reports a sound study examining self-perceived pain changes during walking in patients with osteoarthritis. Pain in Motion previously reported that up to 30% of osteoarthritis patients have central sensitization, and this new study from U.S. researchers suggests a role for central sensitization in explaining pain changes during daily physical activities like walking

Combining pain neuroscience education with hands-on manual therapy in patients with osteoarthritis and central sensitization pain   January 1st, 2014
A systematic literature review recently showed that approximately 30% of patients with osteoarthritis have central sensitization pain, implying that their pain is dominated by central factors (i.e. the increased hyperexcitability of the central nervous system) rather than peripheral (i.e. joint) factors.

Pain neuroscience education for treating Cyberchondria. Is Google really your friend?   January 1st, 2014
The internet is nowadays a popular information source for the general public when it comes to medical advice. It is an easy to use and very cheap source of information, which may lead to less medical consults. On the other hand, it can have several negative effects, like an overload of information, increased anxiety, distress, and compulsive search for medical information. Recently, this phenomenon has been referred to as “Cyberchondria”.

Low back pain: Simultaneous top-down + bottom-up approach for treating central sensitization?   January 1st, 2014
The study by Schabrun et al. published in Brain Stimulation 2014 is one of the most interesting papers I have read last year. This might be due to the fact that I am not at all an expert in neuromodulation, but even so the study is highly innovative and has amazing findings. The paper reports a placebo-controlled cross-over study investigating the effect of transcranial direct current stimulation (tDCS) combined with peripheral electrical stimulation (PES) treatment on pain, cortical organization, sensitization and sensory function in 16 patients with chronic low back pain. It was found that a combined tDCS/PES intervention is more effective for improving not only chronic low back pain symptoms, but also for improving the mechanisms of cortical organization and central sensitization than either intervention applied alone or a sham control.

The Psychological Flexibility Model: A basis for integration and Progress in Psychological Approaches to Chronic Pain Management   January 1st, 2014
A recent article by Lance M. Mc Cracken and Stephen Morley published in the Journal of Pain addresses the place of theory and models in psychological research and treatment development in chronic pain. It argued that such models are not merely an academic issue but are highly practical. Such models ought to integrate current findings, precisely guide research and treatment development, and create progress. The dominant psychological approach to chronic pain is cognitive behavioural therapy (CBT).

Cognitive performance in patients with chronic central sensitization pain   January 1st, 2014
Persistent pain in the absence of structural pathology remains a challenging issue for clinicians. Besides the suffering from the pain itself, chronic ‘unexplained’ pain is often accompanied by other debilitating symptoms such as fatigue, sleep difficulties, dizziness, psychological symptoms, and cognitive problems among others. A growing body of scientific research underlines the involvement of a common pathophysiological mechanism of central sensitization (CS), commonly known as an hypersensitivity of the central nervous system, in overlapping chronic pain conditions such as chronic fatigue syndrome (CFS), fibromyalgia (FM) and chronic whiplash-associated disorders (WAD).

Tea with discussions about combining manual therapy with pain neuroscience education   January 1st, 2014
Interpreting scientific results in clinical practice can be, to say at least, challenging. Especially when it is somewhat contradictory to what you have heard during all those years of extensive training in both physiotherapy education and other courses. As one of my friends recently put it this way: ‘The more I learn about pain, the less I know and the more confused I get.’

WILL COMPUTERS REPLACE THERAPISTS? THERAPEUTIC PAIN NEUROSCIENCE EDUCATION VIA E-MAIL   January 1st, 2014
Therapeutic pain neuroscience education (TPNE) is becoming increasingly popular as (part of) the treatment of (chronic) pain and aims at altering the patient’s thoughts and beliefs about pain. Previous research has demonstrated the efficacy of TPNE in the treatment of chronic pain. TPNE is mostly given in one-on-one sessions, which has limitations, as it is time intensive, cost intensive and limited to patients in remote areas. Pain in Motion previously showed that written TPNE does little to alter pain, pain cognitions or illness perceptions in patients with fibromyalgia.

In the subacromial space or in the brain? Central nervous system sensitization in patients with shoulder pain   January 1st, 2014
Hyperexcitability of the central nervous system, or central sensitization, is considered to be a maladaptive type of neuroplasticity often seen in patients with chronic pain. Central sensitization is frequently seen in patients with osteoarthritis, fibromyalgia, whiplash, neuropathic pain and chronic fatigue syndrome. Up to recently, shoulder pain was considered to be a pure ‘local’ problem. Tissues that are frequently linked to shoulder pain include (rotator cuff) muscles, ligaments, subacromial bursa and joint capsules.
