This feasibility study addresses the applicability of matrix electrodes for the reduction of ongoing pain in cancer patients via low-frequency electrical stimulation (LFS). ⋯ Cutaneous neuromodulation using LFS via a matrix electrode has been shown to be a safe intervention for effectively reducing cancer pain in palliative care patients.

Fully understanding attention to pain requires taking into account the motivational context. Both pain- and (nonpain) goal-related information attracts attention. An intriguing question is which attentional bias prevails when pain- and goal-related information co-occurs? Reduced attentional bias towards pain- and goal-related information was predicted when the other competing information was presented simultaneously. Moreover, trait attentional control was predicted to be associated with stronger attentional bias towards goal-related information particularly in the presence of pain-related information. ⋯ These findings indicate that treatment interventions facilitating goal pursuit in patients with chronic pain are beneficial in reducing attentional biases towards pain-related events.

Fibromyalgia syndrome (FM) is a chronic pain disorder characterized by widespread pain, sleep disturbance, fatigue and cognitive/affective symptoms. Functional imaging studies have revealed that FM and other chronic pain syndromes can affect resting brain activity. This study utilized electroencephalographic (EEG) recordings to investigate the relative power of ongoing oscillatory activity in the resting brain. ⋯ Increased prefrontal theta activity may contribute to persistent pain in fibromyalgia or represent the outcome of prolonged symptoms. The findings point to the potential for therapeutic interventions aimed at normalizing neural oscillations, while further research utilizing quantitative analysis of resting EEG could benefit our understanding of fibromyalgia pathophysiology.

People behave and interact with others differently when experiencing physical pain. Pain has dramatic effects on one's emotional responses, cognitive functions and social interaction. However, little has been known about whether and how physical pain influences interpersonal trust in social interaction. In the present study, we examined the influence of physical pain on trusting behaviour. ⋯ The present work highlights the social component of pain and extends our understanding of mutual interactions between pain and social cognition.

Review Meta Analysis
Exercise for the prevention of low back and pelvic girdle pain in pregnancy: A meta-analysis of randomized controlled trials.
The effect of exercise in prevention of low back and pelvic girdle pain during pregnancy is uncertain. This study aimed to assess the effect of exercise on low back pain, pelvic girdle pain and associated sick leave. ⋯ Exercise has a small protective effect against low back pain during pregnancy.
