Referred Pain Case Study. Referred pain from the cervical spine (and occasionally the thoracic spine) is usually due to compression of a nerve and/or nerve root. In a normal anus of a person, the vein is filled with blood to regulate bowel movements. Referred pain, also called reflective pain, is pain perceived at a location other than the site of the painful stimulus. Referred pain mechanism 2 mechanisms Dermatomal rule Convergence–projection theory. Muscular referred pain, that is, pain perceived in a somatic area other than the site of the noxious stimulation, takes place on a specific place to each muscle in constant and predictable pattern. pain in a shoulder following abdominal laparoscopic procedure). ... what is referred pain? Kosek, E., et. referred pain is presumed to occur because the information from multiple nociceptor afferents converges onto individual spinothalamic tract neurons. Referred pain, also called reflective pain, is pain perceived at a location other than the site of the painful stimulus. An Intensive (or Summation) Theory of Pain (now referred to as the Intensity Theory) has been postulated at several different times throughout history. An Intensive (or Summation) Theory of Pain (now referred to as Referred pain, as defined by Anderson, is “pain felt at a site different from the injured or diseased organ or body part.” 1 Radiating pain, however, is not defined by Anderson; radiating pain is more commonly used in connection with pain perceived in somatic nerve and spinal nerve root distributions (i.e. Acute pain initiates the “fight-or-flight” response of the Autonomic Nervous System and is characterized by the following symptoms: An example is the case of … But referred pain can also occur under less dramatic circumstances unrelated to any cardiac pathology. ORIGIN OF PAIN PATHOLOGY 8 Practical PAIN MANAGEMENT, Nov/Dec 2003 f Referred Pain vs. This theory, initially presented by Charles Bell (1774–1842), is referred to as the specificity theory. Referred pain is pain perceived at a location other than the site of the painful stimulus/ origin.It Recently, Mense 59 suggested an interesting theory, especially from a perspective regarding referred muscle pain, that is known as the central-hyperexcitability theory . The way in which referred pain is caused is unknown, however there are several theories. pain theories study guide by hugsandkisses392 includes 89 questions covering vocabulary, terms and more. Convergent-projection theory. al., (1989) Pain mechanisms underlying vascular headaches, Revue Neurologique, Volume 3, Issue 145, Pages 181–193 There are several proposed mechanisms for referred pain. Currently there is no definitive consensus regarding which is correct. The cardiac general visceral sensory pain fibers follow the sympathetics back to the spinal cord and have their cell bodies located in thoracic dorsal root ganglia 1-4(5). be discriminated by higher centres. This theory, initially presented by Charles Bell (1774–1842), is referred to as the specificity theory. Referred pain: pain that is perceived in an area distant from the site of stimuli (e.g. It is highlighted in musculoskeletal classes as well as pathology classes linking the different systems of the human body. There are a number of theories of referred pain, but only some are relevant to medical world. The neuroanatomic and physiologic theories that explain the phenomenon of referred pain is widely accepted by multiple health care disciplines. An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury. MECHANISMS OF REFERRED PAIN. 2. Referred pain is a phenomenon used to describe pain perceived at a site adjacent to or at a distance from the site of an injury's origin. https://www.sciencedirect.com/science/article/pii/S0306987717301615 Referred pain of peripheral nerve origin: an alternative to the … The aforementioned theories lack some of the referred pain characteristics previously described in this article. Pain may be elicited from heat, chemical, and mechanical stimuli, which are perceived by primary afferent nociceptors in the skin, muscles, and viscera in a process known as transduction. Many scientists continued to do research long after Descartes proposed the dualistic theory of pain. However, it wasn’t until 1811 that another well-known pain theory came onto the scene. This theory, initially presented by Charles Bell (1774–1842), is referred to as the specificity theory. For example, an … Covergence theory- The nerves from the visceral structures and the somatic structures to which pain is referred enter the CNS at the same level and converge on the same spinothalmic neurons. REFERRED PAIN VS. Although this is generally the most accepted theory, there are some other theories that have been developed to explain this as well (see hyperexcitability and axon-reflex theories). 1. The experience of dentally related pain during a heart attack is a classical example of referred pain which is pain felt at a site distant from the site of origin. The difficulty with localizing the source of visceral pain stems from a phenomenon known as referred pain.This is a situation in which pain originating from one part of the body is perceived elsewhere. Therefore, I will briefly discuss a few topics that I believe to … However, reality is much more complex. Based on available data and experience, the author concludes that referred pain is neuropathologic and not nociceptive.
