Beliefs about pain and treatment are socially shared purchase kamagra chewable 100 mg with amex, and include the nature of pain trusted kamagra chewable 100mg, illness cheap kamagra chewable 100mg amex, and disability, attributions about their causation, the efficacy of particular interventions, self-efficacy in implementing treatment, and aspects of pain control, such as choice and predictability. The social context of interpersonal encounters encompasses the social relationships with family, significant others, friends, acquain- tances, workmates, colleagues, health professionals, and alternative practi- tioners. Social motivation incorporates social support, the need for ap- proval of actions to utilize social resources such as family and friends and formal health care resources, and seeking help from alternative therapists. Numerous beliefs, probably in the hundreds, need to be systematically documented and organized taxonomically to understand which are the most important predictors of the response to pain, illness, and treatment outcomes. Patients’ beliefs tend to mirror the general and current views held by the society that they live in, being grounded in that culture. These interpersonal beliefs provides a backdrop for shared group and intergroup understandings at Level 3, and connect with higher order factors such as health culture at Level 4. Beliefs have considerable practical value in under- standing how patients present their condition, and in predicting their re- sponse to advice and compliance with treatment, with erroneous beliefs be- ing particularly prone to perpetuating persistent pain. Identifying several clusters of relevant beliefs, Jensen, Karoly, and Huger (1987) found that pain patients commonly believe that physicians will rid them of pain, that they themselves are not in control of the pain, that others are responsible for helping people in pain, that those in pain are permanently disabled, and that medication is the best form of treatment for pain. These beliefs are conceptualized as reflecting dependency, external health locus of control, absence of positive thoughts about rehabilitation, or catastrophizing, and medicalization, respectively. More recently, Jensen and Karoly (1992) found that among patients reporting low and medium levels of pain, a belief that they were disabled was related to lower activity levels, use of health care services, and poorer psychological functioning. They also found that where patients believed in a medical cure for their pain, this was related to more frequent use of health care services. These results highlight the importance of beliefs in adjustment to chronic pain (Jensen & Karoly, 1992), and it is these types of erroneous beliefs that need to be confronted in psychosocial interventions, such as self-management courses and cognitive behavior therapy, to enable patients to make gains and achieve a sense of control. Much work has been carried out on the concept of self-efficacy in recent years, and numerous findings support the importance of self-efficacy beliefs in response to pain. SOCIAL INFLUENCES ON PAIN RESPONSE 191 also found that pain intensity and self-efficacy contributed to the develop- ment of disability and depression in patients with chronic pain (n = 126). In line with this finding, they suggested that enhancing self-efficacy beliefs is an important therapeutic goal. Lin (1998), studying chronic cancer and low back pain patients, found that for both patient groups, perceived self- efficacy correlated negatively with pain intensity and interference with ev- eryday life. Enhancing perceptions of self-efficacy has yielded significant and clinically meaningful results (Jensen et al. We return to self- efficacy in discussion of Level 3, where an application of this concept through the use of group processes is addressed. Social learning theory and early behavior therapy contained a germ of an idea that spouses and “significant others” were playing a role in the maintenance of pain behaviors. It followed that they needed to be included in pain treatment programs, trained to help diminish damaging pain behav- iors and to support the progress of the program at home. In many pain management programs running today, the inclusion of significant others as part of the program has disappeared, usually for reasons of cost, so the spotlight has again refocused on the individual, leaving a regrettable gap in attention to social factors. Fordyce (1976) gave tacit acknowledgment to the principle that health professionals needed to be trained in behaviorist tech- niques to provide the necessary environment for the program to work—that is, to “extinguish” pain behavior and “reinforce” or “reward” positive or health behavior. These social components are still an integral part of cogni- tive behavior therapy programs. The focus now has shifted from the spouse or significant other to the re- sponse of the family and therefore to family therapy (see Carr, 2000, for re- view). This represents a much better understanding of the response of carers to the pain of a sick spouse. For example, the therapeutic progress of female rheumatoid arthritis patients was found to be substantially impaired when hostility was the predominant response of their husbands to their condition (Manne & Zautra, 1990). Of particular interest here are family ad- justment and adaptation models (Kerns & Weiss, 1994). These emphasize the family as the primary unit of analysis, and the social context as the sa- lient environment in which adaptation or maladaptation occurs. They ex- amine the ways families approach and evaluate the stress of living with someone in a painful condition, and the family’s capacity to deal with these challenges. When considering the individual’s response to pain, it is impos- sible to ignore the impact of these influences.

This maneuver jams the supraspinatus tendon into the anterior surface of the coracoacromial ligament and acromion process generic kamagra chewable 100mg overnight delivery. In this test discount 100 mg kamagra chewable visa, the patient is instructed to supinate the arm purchase 100 mg kamagra chewable overnight delivery, and the examiner resists the patient’s shoulder flexion. In this test, the patient flexes the elbow to 90° while simultaneously inter- nally rotating the shoulder and supinating the forearm against resist- ance. This test is positive and indicates a biceps injury if the maneuver elicits pain over the long head of the biceps tendon (Photo 14). To test more specifically for a SLAP lesion, and to differentiate it from an AC joint injury, the O’Brien test is performed. In this test, the patient stands with the shoulder flexed to 90° and the elbow in full extension. With the patient’s hand supinated, the examiner puts an inferiorly directed force on the patient’s hand. When the maneuver elicits pain inside the shoulder when the hand is in supination, but not when the hand is in pronation, a SLAP lesion is suspected. Therefore, if this maneuver elicits pain in the AC joint, pathology should be suspected in the AC joint and not in the labrum. To test for a supraspinatus tear, perform the empty can test or the drop-arm test. To perform the empty can test, the patient is instructed to abduct the arm to 90° and flex the shoulder to 30°. The patient then internally rotates the arm so that the patient’s thumbs are pointing down (as if emptying a can). Then the examiner pushes down (trying to adduct) the patient’s arms (Photo 16). If there is weakness or pain with this maneuver, the patient may have a tear in the supraspinatus tendon or muscle, or a suprascapular neuropathy. To perform the drop-arm test, passively abduct the patient’s shoul- der to 90° and have the patient slowly lower the arm. If the patient is unable to slowly and smoothly lower the arm without pain, the patient may have a weak or torn supraspinatus tendon or muscle. In this test, the patient is instructed to put the hand behind the back with the dorsum of the hand against the lumbar spine. The patient is then instructed to push posteriorly against the examiner’s resistance (Photo 17). Pain or weakness indicates subscapularis muscle or tendon weakness or injury. If the scapula shifts abnormally, this may reveal an underlying scapular instability. To test for possible anterior instability, the apprehension test is performed. To perform this test, the patient’s shoulder is passively abducted to 90° and the patient’s elbow is flexed to 90°. The examiner then slowly externally rotates the patient’s shoulder (Photo 18). If the patient appears apprehensive and resists this maneuver, the test is pos- itive. It is important to perform this test slowly so as not to injure the patient by actually dislocating the shoulder. The apprehension test is then repeated, but this time, the examiner places additional posteriorly directed pressure onto the patient’s anterior shoulder. By adding this posterior pressure, the patient should no longer be apprehensive with Shoulder Pain 33 Photo 17. This is the relocation test and when it is pos- itive, it confirms anterior shoulder instability.
