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.

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.

To systematically review the current evidence for the effectiveness of Virtual Reality (VR), in conjunction with pharmacologic analgesia on reducing pain and anxiety in burn injury patients undergoing wound dressing changes and physiotherapy management compared with pharmacologic analgesia alone or other forms of distraction. ⋯ This is the first known systematic review to report on the effectiveness of VR, in conjunction with pharmacologic analgesia on reducing pain and anxiety in burn injury patients undergoing wound dressing changes and physiotherapy management compared with pharmacologic analgesia alone or other forms of distraction. Used as an adjunct to the current burn pain management regimens, VR could possibly assist health professionals in making the rehabilitation process for burn patients less excruciating, thereby improving functional outcomes. Further research investigating the effect of VR on anxiety in burn injury patients is warranted.
