Investigating the Effects of Cuing Medication Availability on Patient-controlled Analgesia Pump Usage in Pediatric Patients: Results of a Randomized Controlled Trial.
The study of patient-controlled analgesia (PCA) behaviors has led to a greater understanding of factors that affect the pain experience. Although PCA behaviors can be influenced by cues to medication availability, no studies have examined the effects of such cues in pediatric populations. ⋯ The overall pattern of results suggests that patients in the light group used their PCA in response to the light more than in response to their pain, which likely reflects operant influences on PCA behavior by pediatric patients.

High-Frequency 10▒kHz Spinal Cord Stimulation for Chronic Back and Leg Pain: Cost-consequence and Cost-Effectiveness Analyses.
There is good evidence that spinal cord stimulation (SCS) is effective for reducing chronic back and leg pain (CBLP). SENZA randomized controlled trial showed high-frequency (10 kHz) stimulation (10 kHz-SCS) is clinically superior to traditional low-frequency SCS (LF-SCS).Undertake cost-consequence and cost-effectiveness analysis of 10 kHz-SCS compared with LF-SCS. ⋯ There is a strong economic case for choosing 10 kHz-SCS over LF-SCS for CBLP. Furthermore, 10 kHz-SCS has clinical advantages not captured in our analysis, including shorter, and more predictable procedure times.

Mechanisms of Mindfulness Meditation, Cognitive Therapy, and Mindfulness-based Cognitive Therapy for Chronic Low Back Pain.
This study evaluated theoretically derived mechanisms and common therapeutic factors to test their role in accounting for pain-related outcome change during group-delivered cognitive therapy, mindfulness meditation, and mindfulness-based cognitive therapy for chronic low back pain. ⋯ Cognitive therapy, mindfulness meditation, and mindfulness-based cognitive therapy for chronic low back pain were all associated with significant changes in the primary mechanisms to a similar degree. Change in perceived pain control and pain catastrophizing emerged as potential "meta-mechanisms" that might be a shared pathway that contributes to improved pain-related outcomes across treatments. Further, strong working alliance may represent a critical therapeutic process that both promotes and interacts with therapeutic techniques to influence outcome.

The Effects of a Pain Psychology and Neuroscience Self-Evaluation Internet Intervention: A Randomized Controlled Trial.
Many patients' chronic musculoskeletal pain is strongly influenced by central nervous system processes such as sensitization or amplification. Education about pain neuroscience can change patients' beliefs but has less consistent effects on pain outcomes. Patients may have greater clinical benefits if the educational intervention is personalized, and they evaluate various psychosocial risk factors with respect to their pain. We developed and tested a brief, internet-based Pain Psychology and Neuroscience (PPN) self-evaluation intervention. ⋯ A brief PPN self-evaluation intervention, presented on-line, can yield short-term improvements in musculoskeletal pain severity and interference, especially for people with spinal/localized pain rather than FM, perhaps because the psychology/neuroscience perspective is more novel for such patients.

Evaluation of the Efficacy of Prolonged Pregabalin Administration before and after Surgery in Patients Undergoing Arthroscopic Anterior Cruciate Ligament Repair: A Prospective, Randomized, Double-Blind Study.
Reconstruction of the knee ligament causes postoperative pain and delayed rehabilitation. ⋯ A prolonged preoperative and postoperative pregabalin prescription for anterior cruciate ligament repair decreased the need for supplementary analgesics during the first 24 postoperative hours but increased dizziness.
