Randomized Controlled Trial
Ultrasound-Guided Percutaneous Electrical Nerve Stimulation versus Surgery for Women with Unilateral Carpal Tunnel Syndrome: A Randomized Parallel-group Trial.
The aim of this clinical trial was to compare the outcomes of the application of ultrasound-guided percutaneous nerve stimulation (PENS) targeting the median nerve versus surgery for improving pain and function in women with CTS. ⋯ The application of percutaneous nerve stimulation was more effective at short-term, but similar effective at mid and long-term, than surgery in women with carpal tunnel syndrome.

The Effect of High Versus Low Cognitive Load on the Development of Nociceptive Hypersensitivity: The Roles of Sympathetic Arousal, Sex, and Pain-Related Fear.
According to limited-capacity theories of attention, less attentional resources remain available when engaging in a high- versus a low-demanding cognitive task. This may reduce the perceived intensity and the evoked cortical responses of concomitant nociceptive stimuli. Whether and how the competition for limited attentional resources between a cognitive task and pain impacts the development of long-lasting hypersensitivity is unclear. ⋯ Previous research has mainly focused on cognitive load effects on the perception of acute painful stimuli. Yet this study extends our understanding by investigating cognitive load effects on the development of long-lasting secondary hypersensitivity, a common aspect in numerous persistent pain conditions. As cognitive tasks are presented during a painful procedure inducing secondary hypersensitivity, we test the long-lasting effects of cognitive load. Additionally, we used psychophysiological measurements to explored potential underlying mechanisms involving limited attentional resources and sympathetic arousal.

The selfBACK artificial intelligence-based smartphone app can improve low back pain outcome even in patients with high levels of depression or stress.
selfBACK provides individually tailored self-management support for low back pain (LBP) via an artificial intelligence-based smartphone app. We explore whether those with depressive/stress symptoms can benefit from this technology. ⋯ We have demonstrated that an app supporting the self-management of LBP is helpful, even in those with higher levels of baseline depression and stress symptoms. selfBACK offers an opportunity to support people with LBP and provides clinicians with an additional tool for their patients, even those with depression or high levels of stress. This highlights the potential for digital health interventions for chronic pain.

Oral capsules of tetra-hydro-cannabinol (THC), cannabidiol (CBD) and their combination in peripheral neuropathic pain treatment.
Cannabinoids are often prescribed for neuropathic pain, but the evidence-based recommendation is 'weak against'. ⋯ CBD, THC and their combination did not relieve peripheral neuropathic pain in patients failing at least one previous evidence-based treatment for neuropathic pain.

Effect moderators in internet-based exposure therapy for fibromyalgia: The role of pain intensity.
A recent randomized controlled trial (N = 140) was indicative of large and sustained average improvements of Internet-based exposure for fibromyalgia, as compared to a waitlist. However, little is known about who benefits the most from this treatment. ⋯ This study evaluated potential effect moderators in exposure-based treatment for fibromyalgia. Results indicated that a higher level of pain intensity at baseline was predictive of a less favourable outcome. It may be extra important to monitor progression for these patients and to provide additional therapeutic support when needed.
