Clinical observations suggest that many patients with chronic pain have difficulty forgiving persons they perceive as having unjustly offended them in some way. By using a sample of 61 patients with chronic low back pain, this study sought to determine the reliability and variability of forgiveness assessments in patients and to examine the relationship of forgiveness to pain, anger, and psychological distress. Standardized measures were used to assess patients' current levels of forgiveness, forgiveness self-efficacy, pain, anger, and psychological distress. Results showed that forgiveness-related constructs can be reliably assessed in patients with persistent pain, and that patients vary considerably along dimensions of forgiveness. Furthermore, correlational analyses showed that patients who had higher scores on forgiveness-related variables reported lower levels of pain, anger, and psychological distress. Additional analyses indicated that state anger largely mediated the association between forgiveness and psychological distress, as well as some of the associations between forgiveness and pain. These findings indicate that forgiveness can be reliably assessed in patients with persistent pain, and that a relationship appears to exist between forgiveness and important aspects of living with persistent pain. ⋯ This preliminary study suggests there is a relationship between forgiveness and pain, anger, and psychological distress in patients with chronic low back pain. Patients who report an inability to forgive others might be experiencing higher pain and psychological distress that are mediated by relatively higher levels of state anger.

Clinical Trial
Assessment of pain quality in chronic neuropathic and nociceptive pain clinical trials with the Neuropathic Pain Scale.
Although a number of measures of pain qualities exist, little research has examined the potential for these measures to identify the unique effects of pain treatments on different pain qualities. We examined the utility of the Neuropathic Pain Scale (NPS) for assessing changes in pain qualities after open label lidocaine patch 5% in 3 samples of patients: patients with peripheral neuropathic pain, low back pain, and osteoarthritis. With one exception ("cold" pain in subjects with low back pain), each of the NPS items showed significant change after open label lidocaine patch. In addition, significantly larger changes were observed for the NPS items reflecting global pain intensity and pain unpleasantness and for items assessing sharp and deep pain than for items assessing cold, sensitive, and itchy pain. The pattern of changes in pain qualities did not differ across the 3 diagnostic groups, but it did differ from the patterns of changes in pain qualities associated with other analgesic treatments. The results support the potential utility of the NPS for assessing the patterns of changes in pain qualities that can be observed after pain treatment. ⋯ Pain clinical trials that include measures of pain qualities, such as the NPS, might identify distinct patterns of treatment effects on those pain qualities. This research might be used to help clinicians target analgesics to match the specific qualities associated with a patient's pain and to better understand the mechanisms of analgesic effects in drug development programs.

Randomized Controlled Trial Clinical Trial
A descriptive study of the usage of spinal manipulative therapy techniques within a randomized clinical trial in acute low back pain.
The majority of randomized clinical trials (RCTs) of spinal manipulative therapy have not adequately defined the terms 'mobilization' and 'manipulation', nor distinguished between these terms in reporting the trial interventions. The purpose of this study was to describe the spinal manipulative therapy techniques utilized within a RCT of manipulative therapy (MT; n = 80), interferential therapy (IFT; n = 80), and a combination of both (CT; n = 80) for people with acute low back pain (LBP). Spinal manipulative therapy was defined as any 'mobilization' (low velocity manual force without a thrust) or 'manipulation' (high velocity thrust) techniques of the spine described by Maitland and Cyriax. ⋯ There was a significant difference between the MT and CT groups in their usage of spinal manipulative therapy techniques (chi2 = 9.178; df = 2; P = 0.01); subjects randomized to the CT group received three times more Cyriax Manipulation (29.2%, n = 21/72) than those randomized to the MT group (9.5%, n = 7/74; df = 1; P = 0.003). The use of mobilization techniques within the trial was comparable with their usage by the general population of physiotherapists in Britain and Ireland for LBP management. However, the usage of manipulation techniques was considerably higher than reported in physiotherapy surveys and may reflect the postgraduate training of trial therapists.

The ninth book of the German social code, SGB IX, has intensified questions on the effectiveness and usefulness of medical rehabilitation, a multimodal multidisciplinary team care model, especially but not exclusively for chronic back pain. In 2002 back pain was the reported leading cause for 29 % of all medical and other rehabilitative services provided by German statutory pension funds. A previous systematic review of all available German studies (January 1980 to June 2001) analysed the effectiveness of inpatient rehabilitation for chronic back pain. The present report provides an update and critical appraisal of the review. ⋯ The small size of medium term effects indicates a basic problem of inpatient rehabilitation for chronic back pain in Germany. This becomes even greater when the results of international controlled studies are used as reference. Possible reasons for the disappointing situation (weak methodology, inappropriate selection of patients, weak intervention) are to be discussed. At present, we have no convincing evidence for a general effectiveness of Germany's system of inpatient rehabilitation for chronic back pain.

Comparative Study
Reliability of retrospective clinical data to evaluate the effectiveness of lumbar fusion in chronic low back pain.
Patients in whom a posterior spinal fusion instrumentation had been performed to treat low back pain were asked to recall their preoperative clinical status by retrospectively filling out the same 3 self-evaluation scales they had completed before surgery in a prospective fashion. ⋯ Relying on a patient's recall of preoperative clinical status is not an accurate method to evaluate surgical outcome after posterior spinal fusion instrumentation. Cross-sectional studies may overestimate the effectiveness of surgery.
