To examine the relationship between level of opioid use and Minnesota Multiphasic Personality Inventory (MMPI) findings among chronic pain patients who were about to begin a functional restoration program. ⋯ The results of this study support the hypothesis that increasing levels of pretreatment opioid use is associated with less desirable MMPI profiles, specifically the Disability Profile and, thus, greater levels of pretreatment psychopathology.

The goal of this study was to identify factors associated with decreased disability and lower pain scores 6 months after a multimodal treatment program for fibromyalgia (FM). ⋯ Self-efficacy and adherence are 2 modifiable factors that influence disability and pain intensity in FM. These psychosocial factors need to be addressed in FM treatment programs to assist patients in maintaining posttreatment improvements.

To investigate whether patients with chronic low back pain (CLBP) show "guarded" movements during walking. It is hypothesized that guarding will be reflected by increased lumbar muscle activity during all periods of stride and secondary, relatively lesser relaxation during periods of swing compared with double support. Furthermore, it is hypothesized that higher levels of perceived fear and disability are related to increased muscle activity and less relative relaxation. ⋯ In patients with CLBP, increased lumbar muscle activity during all periods of stride, with comparable alteration between swing and double support, suggests difficulties with total muscle relaxation. On the basis of this evaluation, it is concluded that patients with CLBP show a guarding mechanism during walking. No relationship is found between perceived fear, disability, and muscle activity.

Clinical Trial
Time course of pain relief in patients treated with radiotherapy for cancer pain: a prospective study.
The purpose of this prospective study was to analyze time course of pain relief by radiotherapy for cancer pain. ⋯ Telling approximate time course of pain relief seems to reduce patients' anxiety, and knowing time course of pain relief seems to be useful to determine optimal dose of analgesics that changes according to the course.
