Chronic Neuropathic Pain

Chronic pain is any pain that lasts longer than 3 months (FNLM, 2011). A common type of chronic pain is neuropathic pain which occurs when the nerves themselves are damaged by injury or disease (Veteran Mates, 2013). Neuropathic pain is a complex condition that is often underdiagnosed or undertreated, resulting in negative physical, psychological and social impacts (Veteran Mates, 2013). Therefore early management is critical in order to improve the person’s quality of life and to reduce the chance of the pain becoming persistent (Pain Health, 2015). The following 5 articles relating to the management of neuropathic pain will be annotated, including a summary of the main

This technology is the same as that used for dorsal column stimulation which has been validated for for chronic pain syndrome, failed back syndrome and peripheral neuropathic pain[5]. The pilot study is being performed at the Cleveland Clinic for DBS[6]. Studies have been performed for motor cortical stimulation[7]. Results are variable but promising. Technique varies from institution to institution and a consensus is yet to be reached . Given the dire nature of intractable neuropathic face pain, the lack of effective therapy and reported efficacy of neuromodulation surgery, it is reasonable to offer DBS or MCS in carefully chosen

Validity: Overall the study is valid but limited as the study examined individual patients as a single case making the ability to generalize limited. The foremost dilemma with the study is the challenge in determining the difference in scores that correspond directly to a clinically important modification. The ability of the VAS to detect significant changes relies heavily on an established baseline as a standard to compare future data. Throughout the duration of the study, patients were asked frequently to complete the VAS and RMQ, this may possibly lead to learning effects which may impact the results of the pain and functional status

In order to better understand parkinsonian CNP and determine what part of the circuitry has been disrupted, it is important to understand normal pain physiology. Acute pain is activated in the presence of a noxious stimulus (such as high heat, pressure, or chemicals), to signal potential or actual tissue damage. Noxious stimuli invoke a response from specialized terminals of peripheral nociceptors, whose cell bodies originate in the peripheral dorsal root ganglia located along the spinal column [261]. These terminals contain transient receptor potential channels, tetrodotoxin channels and ion channels that transduce energy from noxious stimuli into action potentials. The speed of the action potential is directly related to the diameter

The discussion of improving the quality of life of these patients was also a bid discussion. Peripheral neuropathy can have a large impact on a person’s day-to-day activities, and disrupt sleep patterns. With this these patients are at risk for injury, decrease mobility, and isolative behaviors (Sibbald, G. 2012). What I learned most from this article was that there are many ways to treat the pain of this disease, and we need to look into the best option for our patients. By doing this we will have a greater chance of improving their quality of life.

The participants recorded their pain during activity using the numerical rating scale (NRS) during the initial examination. The participants received three IASTM treatments a week

These disorders include fibromyalgia, chronic neck pain, osteoarthritis, rheumatoid arthritis, and chronic low back pain. However, there is still indecision as to whether exercise has a positive effect on the processes involved in central pain modulation (CPM) (Nijs, Kosek, Van Oosterwijck, & Meeus, 2012). There is an assumption that exercise-induced endogenous analgesia is the result of endogenous opioids being released and growth factors, along with the activation of (supra) spinal nociceptive inhibitory mechanisms coordinated by the brain (Nijs et al., 2012). An investigation into (CPM) as a potential mechanism of EIH revealed that this was not the case (Ellingson, Koltyn, Kim, & Cook, 2014). The testing for intensity and unpleasant rating to noxious heat stimuli, included painful exercise, non-painful exercise, and quiet rest. According to the findings pain sensitivity, significantly decreased during both types of exercise session but there was no significant change during quiet rest (Ellingson et al.,

Sean Mackey is a M.D, Ph.D, the current Chief of the Division of Pain Medicine, as well as a Redlich professor in several pain and brain related sciences at Stanford. Doctor Mackey leads the research at the Stanford Systems Neuroscience and Pain Laboratory focusing on the dissecting chronic pain and how it effects the nervous system. The SNAPL has also attempted to map out the brain and regions in the spinal cord that understand pain in order to treat these occurrences of chronic pain on a personal level (Stanford Medicine Bio). In order to solve these problems he is mainly explores the effects of different injected drugs, such as Lidocaine, Ondansetron, and Botulinum Toxin, for ameliorating effects or help in linking how different responders

The areas of the brain associated with the “pain matrix,” the right posterior insula and the primary somatosensory cortex, showed a significant increase in activation in response to the control condition during the painful pin prick stimulus compared to no painful stimulus. There was also a significant increase in activation of the right posterior middle temporal gyrus, the middle frontal gyrus, the left supramarginal gyrus, and the precentral gyrus. A portion of the posterior insula was significantly activated during the hypnotic hypoalgesia condition with the painful prick stimuli. The painful prick stimulation in the hypnotic hyperalgesia condition showed an increase in the activation of the inferior parietal lobule, the precentral gyrus, and the posterior insula (Abrahamsen et al., 2010).

The purpose of the study is to assess the immediate responsiveness of conditioned pain modulation (CPM; formerly known as diffuse noxious inhibition control or DNIC) as an outcome variable and its association with neck pain and global rating of change (GROC) in neck function among chronic neck pain sufferers between the 1st to 5th years from the onset of condition. Chronic neck pain is largely non-specific in nature and requires a biopsychosocial understanding of risk factors to mitigate their poor outcome. Practice guidelines highlight the importance of classifying these patients, which includes a biopsychosocial perspective for effective intervention (Cote et al 2016). Recent evidence also points to the success of personalized pain management that is anchored on specific neurophysiologic mechanism underpinning the pain experience of each individual (Nir and Yartniksy 2015). There is emerging evidence that simultaneously evaluating this neurophysiologic mechanism, along with biopsychosocial variables identified risk factors related to the development of chronic neck pain at one year (Shahidi et al 2015). There is extensive literature on pain and function outcome variables relating to biopsychosocial factors. In the past few years, there is growing evidence in the neurophysiologic mechanisms literature that includes CPM/DNIC’s validity and reliability in various chronic pain states. There is a call for CPM/DNIC to be used as outcome variable because it signifies the status

The clinician will then move to the next model of pain. Gate Control was built on the idea that “specificity” really didn’t accurately explain the variations in pain experienced by people. Gate Control says very simply that pain is a “message” – a message that is sent from sensory receptors in a part of the body directly to the brain. The message is transmitted via the spinal cord, and there is a “gate” that controls the transmission in it (this gate is called the dorsal route ganglion, and will come up later as well). When the gate is “open,” the pain message is transmitted in clear, high definition to the brain, and the brain says very clearly: “Pain!” When the gate is “closed,” the message is weakened, or blocked. The brain doesn’t

It is estimated that 20% of the European population suffer from chronic pain.1 The understanding of pain in research has considerably developed from the simplistic pain-gate theory.2,3 It is now understood that stimulation of peripheral nociceptors at high threshold triggers central pathways that travel via the lateral spinothalamic tract to the medulla and brainstem.4 Nociceptive information also arrives via spinoreticular and spinomesencephalic tracts; controlling autonomic, arousal and homeostatic responses.56 Sensory firing is just one influence to central pain processing. Cortical areas associated with emotional valence, memory, autonomic and motor control are all seen to activate during a pain experience supporting

Combination treatment have approved to provide effective treatment for neuropathic pain at lower doses (Tesfaye S, et al 2013, Chaparro LE, et al 2012). Both oxycodone and tramadol with acetaminophen were recommended by The European Federation of Neurological Societies (EFNS) and the American Academy of Neurology (AAN). (Callaghan BC, et al 2012)
