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.
