Randomized Controlled Trial Clinical Trial
An internet-delivered cognitive behavioural therapy pain management programme for spinal cord injury pain: A randomized controlled trial.
Chronic pain is common after spinal cord injury (SCI) and dedicated SCI cognitive behavioural therapy pain management programmes (CBT-PMPs) have a growing evidence base to support their uptake clinically. The development of internet-delivered treatment options may overcome barriers to the access and uptake of centre-based programmes. This study examines such an approach on quality of lie (QoL), pain, mood and sleep. ⋯ This study demonstrates the potential of an internet-delivered SCI specific CBT-PMP in reporting significant statistical and clinical benefit in pain intensity and interference. Strategies to improve engagement are needed.

Randomized Controlled Trial Clinical Trial
Comparing the effectiveness of Integrating Ergonomics and Motor Control to conventional treatment for pain and functional recovery of work-related neck-shoulder pain: A randomized trial.
Work-related neck and shoulder pain (WRNSP) is highly prevalent among patients who seek physiotherapy treatment. Clinicians may tend to focus on teaching home exercises and provide general advice about workplace improvement. The present study investigates the short- and long-term impact of an intervention approach that emphasizes on integrating the motor control re-education with ergonomic advice. ⋯ Integrating ergonomic intervention and motor control training achieved similar reduction in pain and functional outcomes compared to conventional physiotherapy at post-intervention and at 1-year follow-up, for patients with moderate level of work-related neck-shoulder pain and mild degree of functional disability. The Ergo-motor Group reported significantly better perceived overall recovery at 1-year follow-up.

Randomized Controlled Trial Clinical Trial
Complete withdrawal is the most feasible treatment for medication-overuse headache: A randomized controlled open-label trial.
Complete stop of acute medication and/or migraine medication for treatment of medication-overuse headache (MOH) has previously been reported more effective in reducing headache days and migraine days per month compared with restricted intake of acute medication. However, it is unknown whether complete stop or restricted intake is the most feasible treatment for patients. ⋯ A complete stop of all analgesics is the most effective treatment for MOH regarding reduction in headache days but has often been regarded as too challenging for patients. However, in this study, complete stop appears to be more feasible compared with restricted intake of analgesics seen from the patients' perspective.

Randomized Controlled Trial
Ketamine infusion for 96 hr after thoracotomy: Effects on acute and persistent pain.
Why is this significant?
This is the first randomised controlled trial looking at the impact of perioperative ketamine on persistent post-surgical (PPS) pain 1 year after thoracic surgery. Thoracotomy is associated with both severe and a high incidence (up to 50% at 6 months) chronic pain.
Ketamine has important analgesic properties through NMDA blockade, and has been long thought (hoped) that via this it may modify chronic post-surgical pain. Nonetheless, many studies have been unable to show a benefit for ketamine in reducing PPS pain.
What did they show?
Chumbley et al. ran ketamine infusions at 0.1 mg/kg/hour for 96 hours in patients undergoing thoracotomy, starting with a 0.1 mg/kg bolus 10 minutes before surgery. Patients also received either an epidural or paravertebral infusion for post-operative analgesia.
Although there were small differences in acute pain (notably the ketamine group used less PCA morphine) there was no difference in persistent post-surgical pain at 12 months.
Bottom-line
The evidence continues to mount against perioperative ketamine, suggesting it does not reduce persistent post-surgical pain, not-withstanding its acute analgesia benefits. Await results of the ROCKet trial (Reduction Of Chronic Post-surgical Pain with Ketamine) to provide greater clarity...
An afterthought
Notably, the researchers did demonstrate a dramatically lower incidence of PPS pain than for similar studies (27%, 18%, 13% at 3, 6, 12 months) across both the ketamine and placebo group. This suggests that either the study participants were not representative of the typical thoracotomy patient (unlikely), or other care associated with the study had a beneficial effect on reducing PPS – perhaps even via a Hawthorne-like effect.

Randomized Controlled Trial
The effect of total intravenous anaesthesia with propofol on postoperative pain after third molar surgery: a double blind randomized controlled trial.
Total intravenous anaesthesia (TIVA) with propofol may reduce pain after surgery compared with inhalational anaesthetic techniques. Whether propofol provides analgesic benefit may be influenced by the surgical procedure and anaesthetic/analgesic regime. Third molar surgery is a consistent and fairly standard surgical technique that provides a good model for postoperative pain. We investigated whether propofol TIVA or sevoflurane (SEVO) inhalational anaesthesia would produce better quality pain relief after third molar surgery. ⋯ Choice of general anaesthetic technique can affect postoperative analgesia. The results of this study suggest that propofol TIVA improves postoperative pain and patient satisfaction after third molar surgery compared to inhalational anaesthesia.
