It is also rotating x-ray tube and image sensors (detectors), the frequently used in swellings, protuberances and effusions patient table and a computer for processing the data.

However discount fosamax 70 mg otc, using Roth’s (2000) analogy of the double-edged sword purchase fosamax 70 mg on line, it is noteworthy that there are lingering and unwanted scars of this psychodynamic thrust. These include the general tendency to assume (a) that all cases of pain in the absence of identifiable physical pathology are the result of psychological factors, and (b) that these are equally relevant to all people with persistent pain. Although incorrect, these assumptions can (and still often do) have a negative impact on opinions and general treatment of people who suffer from persistent pain conditions. GATE CONTROL THEORY As noted earlier, Melzack and colleagues’ seminal papers on the gate con- trol theory of pain (Melzack & Casey, 1968; Melzack & Wall, 1965) are fre- quently cited as the first to integrate physiological and psychological mech- 40 ASMUNDSON AND WRIGHT anisms of pain within the context of a single model. It is beyond the scope of this chapter to provide a detailed synopsis of the theory; however, given its contribution to current conceptualizations of pain, a brief overview is warranted. Melzack and Wall (1965) proposed that a hypothetical gating mechanism within the dorsal horn of the spinal cord is responsible for allowing or disal- lowing the passage of ascending nociceptive information from the periph- ery to the brain. These essential elements are as follows: · The gating mechanism is influenced by the relative degree of excitatory activity in the spinal cord transmission cells, with excitation along the large-diameter, myelinated fibers closing the gate and along the small- diameter, unmyelinated fibers opening the gate. Since this original proposal we have, of course, moved beyond believing that the key to understanding pain is knowing what happens in the dorsal horn. Melzack and Casey (1968) further proposed that three different neural networks (i. They also recog- nized that processing of input could occur in parallel, at least at the sensory and affective level. This revised model allowed for “perceptual information regarding the location, magnitude, and spatiotemporal properties of the noxious stimulus, motivational tendency toward escape or attack, and cog- nitive information based on analysis of multimodal information, past experi- ence, and probability of outcome of different response strategies” (pp. Think back to the case of Jamie, who had pain associated with muscle strain in the low back. Applying the postulates of the gate control theory, Jamie’s pain experience might be understood as follows: Stimulation of nociceptors in the region of muscle strain facilitated transmission of infor- mation along ascending fibers, through an open gate, and on to Jamie’s brain. At the same time, Jamie’s brain was sending information about her current cognitions and emotional state (i. The summation of the ascending nociceptive input and descending information regarding cognition and 2. BIOPSYCHOSOCIAL APPROACHES TO PAIN 41 emotion, in this case, kept the gate open. Medical and behavioral interventions ultimately served to close the gate, reducing pain, and improving Jamie’s mood state and overall functional ability.
