The International Association for the Study of Pain defines allodynia as pain due to a stimulus that does not normally provoke pain and hyperalgesia as an increased response to a stimulus, which is normally painful. However, does "normally painful" mean "any stimulation of nociceptors" or "the subjective pain response?" We argue that "normally painful"(More)
In patients who experience unilateral chronic pain, abnormal sensory perception at the non-painful side has been reported. Contralateral sensory changes in these patients have been given little attention, possibly because they are regarded as clinically irrelevant. Still, bilateral sensory changes in these patients could become clinically relevant if they(More)
OBJECTIVES The aim of this study is to investigate whether quantitative sensory testing with Von Frey monofilaments (VFMs) can be used for the quantification of allodynia in patients with chronic neuropathic pain, and how the pain threshold of affected skin differs from healthy skin. METHODS Using VFMs, we aimed to determine the pain threshold in 22(More)
Difficult to diagnose pain in the orofacial area may be a challenge to the dental practitioner. There still is uncertainty about the taxonomy of chronic orofacial pain, and even more so about its etiology. Treatment of chronic orofacial pain may aim at goals which are set in advance, but also at the underlying pain mechanisms. The disentanglement of pain(More)
In the current issue of the British Journal of Anaesthesia, Shin and colleagues 1 report that propofol used for the maintenance of general anaesthesia may prevent remifentanil-induced hyperalgesia. In their study, a comparison of propofol and sevoflurane combined with either high dose or low dose of remifentanil for the maintenance of general anaesthesia in(More)
BACKGROUND Allodynia is a common and disabling symptom in many patients with neuropathic pain. Whereas quantification of pain mostly depends on subjective pain reports, allodynia can also be measured objectively with quantitative sensory testing. In this pilot study, we investigated the clinical relevance of quantitative sensory testing with Von Frey(More)
Due to the lack of a specific diagnostic tool for neuropathic pain, a grading system to categorize pain as 'definite', 'probable', 'possible' and 'unlikely' neuropathic was proposed. Somatosensory abnormalities are common in neuropathic pain and it has been suggested that a greater number of abnormalities would be present in patients with 'probable' and(More)
UNLABELLED The 'complex neural pulse'(TM) (CNP) is a neuromodulation protocol employing weak pulsed electromagnetic fields (PEMF). A pioneering paper reported an analgesic effect in healthy humans after 30 minutes of CNP-stimulation using three nested whole head coils. We aimed to devise and validate a stimulator with a novel design entailing a multitude of(More)
OBJECTIVE The aim of this study was to calculate the incidence and prevalence of radiating low back pain, to explore the long-term clinical course of radiating low back pain including the influence of radiculopathy (in a subsample of the study population) and non-radiating low back pain thereon, and to describe general practitioners' (GPs') treatment(More)
BACKGROUND Lumbosacral radicular syndrome (LRS) is a self-limiting, benign, painful and impairing condition caused by lumbar disc herniation and inflammatory processes around the nerve root. Segmental epidural steroid injections (SESIs) are helpful to reduce radicular pain on a short-term basis. It is unknown whether SESIs are an effective addition to usual(More)
