Two hundred fifty patients with low-back pain who underwent lumbar discography followed by computed tomography (CT) are the subject of this prospective study. In 93% of the patients, these combined imaging techniques provided additional useful diagnostic information that affected patient management and the selection of treatment alternatives. Lumbar discography followed by CT proved valuable in determining the significance of equivocal or multiple level abnormalities, determining the type of disc herniation, defining surgical options, and evaluating the previously operated spine. ⋯ The radiographic morphology of the normal herniated and degenerative lumbar discs shown by CT-discography gives unique insight into the pathogenesis of disc degeneration. The complications that followed the 750 discograms were one case of urticaria and one disc space infection. Even with the availability of high resolution CT and MRI, lumbar discography remains the only pain provocation challenge to the lumbar disc.

Randomized Controlled Trial Comparative Study Clinical Trial
A controlled trial of transcutaneous electrical nerve stimulation (TENS) and exercise for chronic low back pain.
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). ⋯ 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.

Since 1982, a total of 88 patients with refractory fibrositis have received treatment as part of an integrated group program within a psychiatric outpatient clinic working closely with the department of rheumatology. The best arrangement proved to be a series of 15 weekly two-hour sessions with groups of 8 patients. The program has three main elements: information, instruction in pain control strategies, and group discussion. ⋯ Our program makes it possible for a greater proportion of patients to learn one or more techniques affording some measure of pain relief. It is important for the therapists to adopt a positive and convincing attitude while restricting themselves to helping the patients to help themselves and avoiding power struggles. They should also be ready to accept the patients and their view of the illness, and not attempt to interpret the illness as the expression of something else.

This study examined the relation between marital satisfaction, psychological distress, self-reported pain, disability, and clinical findings in 63 chronic low-back pain (CLBP) patients from primary health care centers. The relation between marital satisfaction and psychological distress in their spouses was also studied. ⋯ In male CLBP patient couples, marital dissatisfaction and psychological distress were much less significantly related. This gender difference should be taken into account in the treatment of CLBP couples.

Twenty consecutive, chronic low back pain patients admitted to our pain treatment unit completed the Attributional Style Questionnaire (an instrument that detects a cognitive style that is correlated with, and that predicts, depression) and the Beck Depression Inventory. An age, sex, and education-matched group of normal subjects, a group of patients with asymptomatic essential hypertension, and a group of patients with end-stage renal disease receiving dialysis treatment served as controls. The majority of the chronic-pain and renal-dialysis patients had elevated depression scores, whereas none of the normal subjects or hypertensive patients were outside the nondepressed range. ⋯ The results of this study suggest that individuals with a chronic medical condition, either symptomatic (chronic low back pain or renal disease) or asymptomatic (essential hypertension) in nature, develop an attributional style characteristic of depression. These data neither lend support nor refute the thesis that chronic pain syndromes are a variant of, or a masked, depression. Rather, this research implies that a more important question is what identifiable risk factors (for example, attributional style) predispose patients with chronic pain to develop a depressive illness.
