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.

Comparative Study
American and Japanese chronic low back pain patients: cross-cultural similarities and differences.
The study compared and contrasted medical, psychological, social and general behavioral functioning of American and Japanese low back pain patients and normal controls. The Sickness Impact Profile and a standardized Medical Examination Protocol for Pain instrument were used to assess all subjects. Findings showed that the American and Japanese low back pain patients had similar and significantly higher medical-physical findings than their respective controls. ⋯ Finally, despite similar medical and physical findings, the Japanese low back pain patients were significantly less impaired in psychological, social, vocational, and avocational functioning than the American low back pain patients. It was concluded that there were significant cross-cultural differences between the American and Japanese low back pain patients, primarily in the psychosocial and behavioral areas. However, given the small sample size, any conclusion should be considered with caution; replication is needed before more definite conclusions are possible.

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.
