Comparative Study
Self-report and pain behavior among patients with chronic pain.
To determine the relationship between pain behaviors and self-report of pain and disability in patients with chronic pain. ⋯ Findings suggest that pain behavior observation is a valid and reliable assessment tool for use with a heterogeneous chronic pain population. Significant associations were found between pain behaviors and self-report measures of pain intensity, pain disability, and self-efficacy; pain intensity scores displayed a weak relationship; and pain disability scores the strongest relationship with pain behavior. Viewed with previous research, the results of this study indicate the value of a multimodal, cognitive-behavioral approach to assessing patients with chronic pain.

Comparative Study
Chronic pain and posttraumatic stress symptoms in litigating motor vehicle accident victims.
There has been little research examining chronic pain and posttraumatic stress symptoms in persons injured in motor vehicle accidents. The purpose of this study was to evaluate differences in physical injury and impairment, psychological distress, and pain coping strategies in litigating chronic pain patients low and high in motor vehicle accident-related posttraumatic stress symptoms. ⋯ Chronic pain and posttraumatic stress symptoms in litigating motor vehicle accident victims are associated with increased physical and psychological morbidity.

To evaluate muscle strength, as a component of physical deconditioning, and central activation ratio, representing the performance level during testing, in patients with chronic low back pain as compared to healthy controls, and to evaluate the contribution of cognitive-behavioral and pain-related factors to the central activation ration of patients with chronic low back pain. ⋯ When interpreting decreased muscle strength in terms of physical deconditioning in patients with chronic low back pain, submaximal performance has to be taken into account. The results suggest that patients with chronic low back pain who report increased psychologic distress and a higher level of current pain tend to show increased inhibition of muscle activity, leading to submaximal performance.

Randomized Controlled Trial Meta Analysis Comparative Study Clinical Trial
The time to onset and overall analgesic efficacy of rofecoxib 50 mg: a meta-analysis of 13 randomized clinical trials.
To determine the time to onset of analgesia of rofecoxib based on a patient-level meta-analysis of randomized, placebo-controlled, postoperative oral surgery pain studies. ⋯ In this meta-analysis of over 1200 rofecoxib-treated patients, a single dose of rofecoxib 50 mg demonstrated a rapid onset of analgesia in approximately half an hour combined with sustained effectiveness, supporting its use as a treatment of acute pain.
