A number of treatments are widely prescribed for chronic back pain, but few have been rigorously evaluated. We examined the effectiveness of transcutaneous electrical nerve stimulation (TENS), a program of stretching exercises, or a combination of both for low back pain. Patients with chronic low back pain (median duration, 4.1 years) were randomly assigned to receive daily treatment with TENS (n = 36), sham TENS (n = 36), TENS plus a program of exercises (n = 37), or sham TENS plus exercises (n = 36). After one month no clinically or statistically significant treatment effect of TENS was found on any of 11 indicators of outcome measuring pain, function, and back flexion; there was no interactive effect of TENS with exercise. Overall improvement in pain indicators was 47 percent with TENS and 42 percent with sham TENS (P not significant). The 95 percent confidence intervals for group differences excluded a major clinical benefit of TENS for most outcomes. By contrast, after one month patients in the exercise groups had significant improvement in self-rated pain scores, reduction in the frequency of pain, and greater levels of activity as compared with patients in the groups that did not exercise. The mean reported improvement in pain scores was 52 percent in the exercise groups and 37 percent in the nonexercise groups (P = 0.02). Two months after the active intervention, however, most patients had discontinued the exercises, and the initial improvements were gone. We conclude that for patients with chronic low back pain, treatment with TENS is no more effective than treatment with a placebo, and TENS adds no apparent benefit to that of exercise alone.

This double-blind, randomized study was designed to compare the effectiveness of intravenous regional sympatholysis using guanethidine, reserpine and normal saline. Twenty-one patients with reflex sympathetic dystrophy of an upper or lower extremity were enrolled and received intravenous regional blockade (IVRB) with one of the three medications. There was significant pain relief in all three groups at 30 min. There were no significant differences among the three groups in the degree of pain relief, the number of patients obtaining pain relief in the 30 min after the block, or the number of patients reporting more than 50% pain relief for more than 24 hr. The saline group's high rate of pain relief could be partially due to a mechanism of tourniquet-induced analgesia.

A battery of standardized psychometric tests was administered to a group of 47 episodic tension-type headache sufferers and 47 headache-free controls. Compared to controls, headache subjects showed higher levels of anxiety, depression, and anger/hostility. The groups did not differ significantly on a measure of anger expressed toward persons or objects, but headache subjects showed significantly greater levels of suppressed anger. The results provide objective data that are in general agreement with predictions derived from psychosomatic theories about the interrelationships among anxiety,

The chairpersons of the state and provincial ethics committees and the executive directors of licensing boards were surveyed in regard to the frequency of complaints of sexual impropriety filed against psychologists during 1982 and 1983. The survey also concerned the disposition of the complaints and whether the psychologist alleged that the therapeutic relationship had terminated before the initiation of the sexual relationship. The findings indicated that a considerable number of complaints had been filed, that close to half had led to findings of violations by the psychologists, and that psychologists asserting that a sexual relationship had occurred only after the termination of the therapeutic relationship were more likely to be found in violation than those not making that claim. Implications of these findings arc discussed, and we recommend that the American Psychological Association's Code of Ethics be modified to include a statement regarding sexual relationships with former clients.Health professionals have long held that sexual intimacy between psychotherapists and their clients is unethical

Test-based psychological assessment is threatened by the policies of managed care organizations; however, research has demonstrated that test-based psychological assessment is quite valuable and economically justified when conducted by well-trained psychologists. This surfaces the question of the current status of graduate training in test-based psychological assessment. Results of this study indicate that clinical and counseling students currently receive almost equivalent training in test-based assessment. However, in a larger context, results indicate a lack of sound preparation in test-based assessment training for a large proportion of clinical and counseling students. These findings are discussed in terms of their implications for the field and, more specifically, for graduate and internship training.

The concept of competence has become the driving force in the education and training of professional psychologists. In fact, competence has evolved into increasingly sophisticated forms, now perhaps best represented by the cube model, which integrates foundational, functional, and developmental variables into ideas about professional training. This article considers one component of professional training, scientific knowledge, and argues that knowledge competence, measured by the Examination for Professional Practice in Psychology, should occur before a student is certified as internship ready.
