An endogenous central nervous system pain-modulating network, with links in the mid brain, medulla, and spinal cord, has recently been discovered. This system produces analgesia by interfering with afferent transmission of neural messages produced by intense stimuli.

NEUROPHYSIOLOGY OF PAIN PDF


Nociception refers to the system that carries signals of damage and pain from the tissues; it is the physiological event that accompanies pain.

Neurophysiology of Pain (Techniques Overview)

Nociceptors can detect mechanical, thermal, and chemical stimuli, and are found in the skin and on internal surfaces such as the periosteum or joint surfaces. Physiological pain is a means of detecting a noxious input where the perception of pain neurophysiology of pain proportional to the intensity of the stimulus.

Physiological pain neurophysiology of pain well localized, transient, and plays a vital role in the body's normal defense mechanisms by initiating protective reflex.

Recent definitions, such as that adopted by the International Association for the Study of Pain [14]have attempted to encompass the multidimensional character of pain by emphasizing that it is not simply a sensory experience, but that it has important emotional and motivational components as well.

The subjective neurophysiology of pain private nature of neurophysiology of pain means that it is often difficult to describe.

Nevertheless, it is essential that the physician obtains a clear description in order to facilitate neurophysiology of pain diagnosis and assessment of response to treatment. A number of techniques have been developed that evaluate pain indirectly using self-rating scales, behavioural observational scales, and assessment of physiological responses [15].

Neurophysiology of pain and numeric pain-rating scales, characterised by the visual analogue scale VASquantify the intensity and magnitude of pain but do not consider other components.

Neurophysiology of pain.

More descriptive scales, such as the McGill Pain Questionnaire, attempt to quantify these other components and have been used neurophysiology of pain to study the effects of various methods of pain management. In clinical practice, however, the use of these instruments has proved less helpful, and the practitioner remains heavily dependent on a good clinical history.

In many patients the origins of musculoskeletal pain are confusing, but experimental studies are now providing valuable insights into the mechanisms neurophysiology of pain which symptoms may arise.

At least in part, the varied range of symptoms neurophysiology of pain be explained by the often complex relationship between the nervous system and the underlying disease. It is now appreciated that pain depends not only on tissue injury, if any, but also on functional changes within the nervous system [16].

Neural pathways are inherently 'plastic' and can be modified extensively according to different conditions. The extent of these changes may well vary between individuals, and in some circumstances persist long after the initiating stimulus has resolved.

A key aspect of neurogenic plasticity involves changes to the sensitivity of individual neurones at neurophysiology of pain peripheral and central levels. Within the joint, injury or inflammation inevitably produces sensitisation and subsequent activation of articular sensory receptors.

Slow neurophysiology of pain is stimulated by chemical stimulation, is poorly localized and is described as an aching, throbbing or burning pain. These neurons release the excitatory neurotransmitter glutamate at their synapses.
