Extending postu- lates of the operant model of chronic pain discount dapoxetine 90mg overnight delivery erectile dysfunction caused by jelqing, Philips (1987) incorporated ele- ments of the cognitive theory of avoidance (Seligman & Johnson dapoxetine 30 mg without prescription erectile dysfunction lack of desire, 1973) to explain cases where behavioral withdrawal was observed to continue in the absence of adequate reinforcement. Avoidance was viewed as a product of pain severity, a preference for minimizing discomfort, and cognitions (com- prising expectancies, feelings of self-efficacy, and memories of past expo- sures) that reexposure to certain experiences or activities will result in pain and suffering.

In this context, then, confrontation is conceptualized as an adaptive re- sponse that is associated with behaviors that promote recovery. Avoid- ance, on the other hand, is viewed as a maladaptive response that leads to a number of undesirable consequences. These include limitations in activ- ity, physical and psychological consequences that contribute to disability, continued nociceptive input (which, like the Glasgow model, may not neces- sarily be related to original injury; also see Norton & Asmundson, 2003), and further catastrophizing and fear. Empirical Overview Vlaeyen and Linton (2000) published a state-of-the-art review showing an ever-increasing number of findings that corroborate postulates of fear- avoidance models. Precursors of pain-related fear, including anxiety sensi- tivity and health anxiety (i. For example, in a sample of chronic musculoskeletal pain patients, Asmundson and Taylor (1996) found that anxiety sensitivity directly influences fear of pain, which, in turn, directly influences self-reported escape/avoidance behavior. There is converging evidence demonstrating that fear of pain affects the way people attend and respond to information about pain (As- mundson, Kuperos, & Norton, 1997; Eccleston & Crombez, 1999; Hadjistav- ropoulos, Craig, & Hadjistavropoulos, 1998; McCracken, 1997; Peters, Vlae- yen, & Kunnen, 2002; Snider, Asmundson, & Weise, 2000). Likewise, there is mounting evidence that fear of pain influences physical performance and is more strongly related to functional disability than are indices of pain sever- ity (Crombez, Vervaet, Lysens, Baeyens, & Eelen, 1998; Crombez, Vlaeyen, Heuts, & Lysens, 1999; McCracken, Zayfert, & Gross, 1992; Vlaeyen et al. Finally, at the practical level, specifically treating the “fear” component using techniques known to be effective in reducing fears (i. METHODOLOGY IN WASHBACK STUDIES 51 musculoskeletal pain (Linton, Overmeer, Janson, Vlaeyen, & de Jong, 2002; Vlaeyen, de Jong, Geilen, Heuts, & van Breukelen, 2001; Vlaeyen, de Jong, Onghena, Kerckhoffs-Hanssen, & Kole-Snidjers, 2002). TOWARD AN INTEGRATED DIATHESIS–STRESS MODEL Our presentation of the various faces of pain shows, to a large degree, a de- velopmental progression from the simplistic notions of somatogenic and psychogenic causation through to the increasingly elaborate yet parsimoni- ous postulates of the contemporary multidimensional, biopsychosocial ap- proaches. In scanning the essential elements of the various models consid- ered under the rubric of “biopsychosocial,” certain consistencies and themes are apparent. These include recognition of the importance of (a) some physiological pathology (which may not remain the same as that as- sociated with initial nociception), (b) some form of vulnerability (diathesis), (c) a tendency to catastrophically misinterpret somatic sensations and re- spond to them in maladaptive ways, and (d) the development of a self- reinforcing vicious cycle that serves to exacerbate and maintain symptoms and functional disability. Taking an approach similar to that employed by Sharp (2001) in his recent reformulation of Turk and colleagues biobe- havioral model of pain (Turk, 2002; Turk & Flor, 1999; Turk et al. It is important to keep in mind that pain and pain behaviors do not occur in isolation. Rather, they are communicated in (see Hadjistavropoulos & Craig, 2002) and influenced, for better or worse, by one’s social, interper- sonal, and cultural milieu (e. For example, a supportive environment can facilitate efforts to cope with pain; however, if there is not enough or, indeed, too much support (i. This appears to hold true for interactions with signifi- cant others as well as those responsible for medical care, litigation, and other such responses (see Sharp, 2001). Similarly, social modeling and social learning experiences influence strongly the way in which one interprets and responds to signs and symptoms of illness (e. So, interpre- tation and behavioral responses to pain depend, to some degree, on what is learned from seeing others in pain and from cultural norms. This is recog- nized, to varying degrees, in all of the biopsychosocial models discussed ear- lier and provides the umbrella under which our model is placed. As illustrated, our integrated diathesis–stress model recognizes the im- portance of physiological, psychological, and sociocultural factors in the etiology, exacerbation, and maintenance of chronic pain.

The medullary mechanisms involved in this are complex and include the response of the solitary nucleus to baroreceptor stimulation (Ghione purchase dapoxetine 30mg chlamydia causes erectile dysfunction, 1996) buy dapoxetine 30mg cheap erectile dysfunction young men. Stressor-induced, increased blood pressure stimulates carotid barorecep- tors, and these in turn activate the solitary nucleus, which then initiates ac- tivity in descending pathways that gate incoming nociceptive traffic at the dorsal horn of the spinal cord. This mechanism links psychophysiological response to a stressor with endogenous pain modulation. Some investigators emphasize that neuroendocrine arousal mechanisms are not limited to emergency situations, even though most research empha- sizes that such situations elicit them (Grant, Aston-Jones, & Redmond, 1988; Henry, 1986). In complex social contexts, submission, dominance, and other transactions can elicit neuroendocrine and autonomic responses, modified perhaps by learning and memory. This suggests that neuroendocrine proc- esses accompany all sorts of emotion-eliciting situations. The hypothalamic PVN supports stress-related autonomic arousal through neural as well as hormonal pathways. It sends direct projections to the sympathetic intermediolateral cell column in the thoracolumbar spinal 3. PAIN PERCEPTION AND EXPERIENCE 75 cord and the parasympathetic vagal complex, both sources of preganglionic autonomic outflow (Krukoff, 1990). In addition, it signals release of epineph- rine and norepinephrine from the adrenal medulla. ACTH (adrenocortico- trophic hormone) release, although not instantaneous, is quite rapid: It occurs within about 15 seconds (Sapolsky, 1992). These considerations impli- cate the HPA axis in the neuroendocrinologic and autonomic manifestations of emotion associated with tissue trauma. In addition to controlling neuroendocrine and autonomic nervous sys- tem reactivity, the HPA axis coordinates emotional arousal with behavior (Panksepp, 1986). As noted earlier, stimulation of the hypothalamus can elicit well-organized action patterns, including defensive threat behaviors and autonomic arousal (Jänig, 1985). The existence of demonstrable behav- ioral subroutines in animals suggests that the hypothalamus plays a key role in matching behavioral reactions and bodily adjustments to challeng- ing circumstances or biologically relevant stimuli. Moreover, stress hor- mones at high levels, especially glucocorticoids, may affect central emo- tional arousal, lowering startle thresholds and influencing cognition (Sapolsky, 1992). Saphier (1987) observed that cortisol altered the firing rate of neurons in limbic forebrain. Clearly, stress regulation is a complex, feedback-dependent, and coordinated process. The hypothalamus appears to take executive responsibility for coordinating behavioral readiness with physiological capability, awareness, and cognitive function. Chapman and Gavrin (1999) suggested that prolonged nociception may cause a sustained, maladaptive stress response in patients. Signs of this in- clude fatigue, dysphoria, myalgia, nonrestorative sleep, somatic hyper- vigilance, reduced appetite and libido, impaired physical functioning, and impaired concentration. In this way, the emotional dimension of persisting pain may, through its physiological manifestation, contribute heavily to the disability associated with chronic or unrelieved cancer pain. Central Serotonergic Pathways The serotonergic system is the most extensive monoaminergic system in the brain. It originates in the raphé nuclei of the medulla, the pons, and the mesencephalon (Grove, Coplan, & Hollander, 1997; Watson, Khachaturian, Lewis, & Akil, 1986).
