Randomized Controlled Trial
The Role of Negative Affect and Experiential Avoidance in Postsurgical Pain and Fatigue Among Norwegian Women With Breast Cancer.
Women undergoing breast cancer surgery frequently experience postsurgical pain and fatigue, which reduces their quality of life. Although psychological factors have been shown to play a role in predicting postsurgical outcomes, the subacute recovery phase often remains underexplored. In this secondary analysis of data from a randomised controlled trial, we sought to investigate the predictive role of negative affect and experiential avoidance on postsurgical symptoms during both acute and subacute recovery. ⋯ Women with higher levels of negative affect and experiential avoidance before undergoing breast cancer surgery appear to be at greater risk for experiencing heightened acute postsurgical pain and fatigue. The identification of these psychological predictors can help clinicians recognise individuals at risk for severe postoperative symptoms and develop targeted preventive and curative interventions to mitigate these symptoms and prevent them from becoming chronic.

We examined de-functionalization and temporal functional recovery of C-nociceptor evoked pain after topical 8% capsaicin applied for 4 consecutive days. ⋯ Sinusoidal electrical stimulation can still activate small diameter axons desensitized to heat after 4 consecutive days of topical 8% capsaicin application and reveals differential temporal functional regeneration of C-nociceptor sub-types. Electrical sinusoidal stimulation may detect such axons that no longer respond to heat stimuli in neuropathic skin.

Sensory profiling in neuropathic pain using quantitative sensory testing (QST) has not been extended to central neuropathic pain due to spinal cord injury (SCI). This study aims to fill this gap by evaluating sensory profiles in patients with neuropathic SCI pain. ⋯ The evaluation of sensory phenotypes by quantitative sensory testing in central neuropathic pain due to SCI adds a new perspective on sensory phenotypes in comparison to peripheral neuropathic pain. The described thermal and mechanical hyperalgesia combination might represent involvement of the spinothalamic tract. In addition, there was a trend towards older age and longer time since injury in patients with loss of function.

Motivation can be investigated with the BIS (Behavioural Inhibition System)/BAS (Behavioural Activation System) scale. BAS regulates the motivation to approach goal-oriented outcomes, particularly rewarding stimuli and situations, while BIS regulates escape and avoidance of unpleasant outcomes. Chronic whiplash-associated disorders (WAD) is a heterogenous pain condition with known alterations in motivated behaviour. The study aimed (1) to investigate the relationship between BIS/BAS, and pain and disability with quality of life and psychological measures in chronic WAD; (2) to determine if BIS and/or BAS mediate the relationships between pain, disability, and psychological symptoms and quality of life. ⋯ In line with current theories, we found a large proportion (30%-50%) of patients with whiplash-associated disorders (WAD) showing signs of altered function in the Behavioural Inhibition System (BIS) and Behavioural Activation System (BAS) suggesting altered reward processing and motivation in these patients. While such altered functions showed associations with pain interference, disability and all mental health measures, reward processing could no be demonstrated as a pathogenetically relevant factor in chronic WAD patients.

The internet is increasingly used as a primary source of information for patients with musculoskeletal pain. Private physiotherapy practices provide informative content on low back pain (LBP) and neck pain (NP) on their websites, but the extent to which this information is biopsychosocial, guidelines-consistent, and fear-inducing is unknown. The aim of this study was to analyse the information on websites of private physiotherapy practices in the Netherlands about LBP and NP regarding consistency with the guidelines and the biopsychosocial model and to explore the use of fear-inducing language. ⋯ This study revealed that the majority of private physiotherapy practice websites that provide information on LBP and NP are inconsistent with the biopsychosocial model and current guidelines. This information has a negative impact on patients' knowledge, attitudes, beliefs, and expectations, potentially affecting treatment outcomes. Consequently, most physiotherapy practice websites are unreliable sources of information on LBP and NP for patients. There is an urgent need to implement strategies to make websites reliable and helpful sources of information.
