Randomized Controlled Trial Comparative Study Clinical Trial
Sensitivity of pain rating scales in an endoscopy trial.
The purpose of this study was to compare the sensitivity of two commonly used pain-rating scales, the Visual Analog Scale and the 4-point verbal rating scale. Both are considered reliable and valid, but previous studies regarding sensitivity of rating scales have lead to different conclusions, and there is no firm agreement as to the best scale to choose. ⋯ Because each individual provided one Visual Analog Scale and one 4-point verbal rating scale rating for the same pain experience, the ability of the two scales to detect differences between groups of pain ratings could be compared. The use of a simulation model enabled estimation of a power function and reduced the probability of basing the conclusion on a chance finding.

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.

Randomized Controlled Trial Comparative Study Clinical Trial
Physicians' assessments versus measured symptoms of complex regional pain syndrome type 1: presence and severity.
To assess the validity of physician's judgements of symptoms associated with Complex Regional Pain Syndrome Type 1. ⋯ We conclude that establishing the presence of Complex Regional Pain Syndrome Type 1 symptoms, except for temperature and volume asymmetries, and monitoring of disease progression based on these symptoms can be performed by clinical judgment. The severity of the individual symptoms evaluated in this study should be measured with reliable and valid measurement instruments.

Randomized Controlled Trial Comparative Study Clinical Trial
Pain report and pain-related evoked potentials operantly conditioned.
The purpose of the present study was to answer the question whether pain report can be increased and decreased by operant conditioning. We predicted that the conditioned pain effects would remain significant after correction for social desirability and fantasy proneness. Furthermore, we tried to show that the neurophysiologic basis of verbal pain report, defined by pain (event)-related potentials, was affected by the conditioning procedure. Specifically, it was expected that the central recording site N150-P260 pain (event)-related potentials peak-to-peak amplitude would show the largest effect. ⋯ We concluded that the subjective report of pain as well as a specific pain-related potentials component can be operantly conditioned.

Randomized Controlled Trial Clinical Trial
The effects of cognitive-behavioral and physical therapy preventive interventions on pain-related sick leave: a randomized controlled trial.
Recent recommendations suggest that reassuring patients with an acute bout of low back pain and encouraging a return to normal activities may be helpful in preventing the development of chronic disability. There is also a question as to whether psychologic or physical therapy interventions actually add anything to such reassurance and advice in terms of preventing chronicity. This study aimed to ascertain the preventive effects on future sick leave and health-care utilization of adding on a cognitive-behavioral group intervention or a cognitive-behavioral group intervention and preventive physical therapy (focused on activity and exercise) relative to a minimal treatment group (examination, reassurance, and activity advice). ⋯ Taken as a whole, this study shows that adding cognitive-behavioral intervention and cognitive-behavioral intervention and preventive physical therapy can enhance the prevention of long-term disability. There was no substantial difference in the results between the cognitive-behavioral intervention group and cognitive-behavioral intervention and preventive physical therapy group.
