CHAPTER 3 Pain Perception, Affective Mechanisms, and Conscious Experience C. Richard Chapman Pain Research Center, Department of Anesthesiology, University of Utah Pain has afflicted humankind since the dawn of human self-awareness, yet we are still struggling to understand its nature. Young physicians in train- ing, whose job it will be to prevent or relieve pain in myriad medical set- tings, listen to instructors who teach about pain receptors, pain pathways, and mechanisms that gate pain at the dorsal horn of the spinal cord. Con- tinuing medical education efforts sustain and enhance the same message, implying that pain is a primitive sensory signal. Specific sensory end organs transduce injury and transmit “pain,” and along the pathway from the pe- riphery to the brain, descending modulatory pathways gate this transmis- sion.
Even with this form of treatment order lipitor 5 mg mastercard cholesterol test can i drink coffee, however purchase 20 mg lipitor fast delivery cholesterol medication for high triglycerides, there is a need for further research evaluations. A number of valuable recommenda- tions in this regard have been made (e. Morley and Williams (2002) most recently highlighted some of the issues that deserve reflection for those considering conducting and evaluating psychological treatments for chronic pain. A significant chal- lenge, for instance, is to understand why patients vary in their response to treatment and to develop interventions that are sensitive to individual needs. They further noted that there are severe limits to the extensive test- ing of all the parameters of treatment such as length and intensity. In this regard, they suggested that the way to move forward is through articula- tion of theories of change, of both specific and process components, to guide research on efficacy and effectiveness of treatment. In the selection and development of outcome measures they suggested that we need to ex- amine the needs of various stakeholders and that both qualitative and quantitative approaches to this research are required. Schwartz and colleagues (Schwartz, Cheney, Irvine, & Keefe, 1997) cau- tioned that clinical research on psychosocial interventions has flourished in the past two decades, and that due to the wide availability of interven- tions, reliance on standard no-treatment control conditions is really no lon- ger possible. A new design for randomized clinical trials is described by Schwartz’s group (1997) that does not require a no-treatment control group, and that potentially identifies dose-response relationships between inter- ventions and treatment outcomes. They proposed use of a three-arm varia- tion of a standard crossover trial. In the first arm patients receive active treatment followed by standard care; in the second arm patients receive standard care followed by active treatment; and in the third arm, patients receive active treatment throughout, allowing also for the study of dose- response relationships. The design avoids ethical difficulties by ensuring all 296 HADJISTAVROPOULOS AND WILLIAMS patients receive treatment and also in the final arm allows for study of the process of change. Most studies are hopelessly underpowered for their aims, and the use of treatment rather than no-treatment controls (as recommended) will require even larger samples to show differences. Based on review of the research as it stands, it is apparent that many pa- tients have benefited from the development of psychological interventions outlined here and are substantially better served than they were 40 years ago. There is now widespread acceptance for the role of psychological in- terventions in the treatment of chronic pain, and, in particular, it has been recommended that pain treatment facilities, in addition to physical therapy and education, include CBT on a routine basis (Fishbain, 2000). At the present time a CBT approach would appear to have the greatest support in working with pa- tients. Within this approach, however, there is considerable variability in how this can be applied, and until further research is available, clinicians are likely to continue to tailor their approach to the needs of the patients. To maintain the rate of improvement we have achieved, a critical apprecia- tion of where we are now is needed, as well as continued attempts to over- come methodological challenges in research already noted. Above and be- yond improved research as described earlier, routine audit and publication of outcomes of existing clinical programs would be highly beneficial so that best practice can evolve from the widest possible clinical base.
