Trunk co-contraction during lifting may reflect a guarded motor response to a threatening task. This work estimated the impact of pain catastrophizing on trunk co-contraction during lifting, in people with and without low back pain. ⋯ This work contributes evidence that people with back pain commonly exhibit trunk co-contraction when lifting. The lack of a relationship between pain catastrophizing and trunk co-contraction, however, challenges evidence linking psychological factors and guarded motor behaviour in this group. Together, this suggests that other factors may be stronger determinants of co-contraction in people with LBP or that a general construct like pain catastrophizing may not accurately represent this relationship.

The central sensitization inventory (CSI) is a questionnaire that has been widely used as a tool for assessing symptoms associated with sensitization. However, its ability to identify individuals with this phenomenon has recently been questioned. The aim of this study was to assess the correlation of CSI with psychosocial and psychophysical factors in patients with painful TMD diagnosed according to diagnostic criteria for temporomandibular disorders (DC/TMD) and asymptomatic controls, as well as to determine the influence of these variables on the CSI scores variations. ⋯ The research highlights a noteworthy relationship between the central sensitization inventory and psychological factors, emphasizing their substantial influence on inventory values. This correlation offers crucial insights into mental health markers within the questionnaire. Additionally, the lack of connection with pain amplification implies a necessary re-evaluation of the inventory's diagnostic suitability, especially in cases of painful temporomandibular disorders. Thus, caution is urged in its application for identifying CS in these individuals.

Mental defeat is considered a potential risk factor for suicidal thoughts and behaviours in chronic pain. This study evaluated the role of mental defeat in predicting future suicide risk and examined whether depression influences this relationship. ⋯ This study strengthens the evidence linking mental defeat with heightened suicide risk in chronic pain. By providing prospective data, it clarifies the temporality of this relationship. Given that suicide risk doubles in chronic pain patients, whereby comorbid depression is common, these findings have crucial clinical implications. Both mental defeat and depression are modifiable. Addressing them together in treatment may help reduce suicide risk in this population.

Epidemiological surveys have monitored chronic non-cancer pain (CNCP) and investigated associated factors in Denmark for more than 20 years. This study aimed to analyse CNCP prevalence in the Danish population from 2000 to 2023 and its associations with mental health status and loneliness. ⋯ This study demonstrated alarming trend on chronic non-cancer pain prevalence over time in Denmark. The high estimates of prevalence and related issues, such as mental health and severe loneliness deserve further investigation and prioritisation in the public health agenda.

The Multidimensional Psychological Flexibility Inventory (MPFI) is a measure of all facets of psychological flexibility and inflexibility, potentially important processes of change in psychological treatment for chronic pain. In some contexts, it can be considered too long. The aim of this study was, therefore, to validate a short form MPFI (MPFI-24P) in a chronic pain sample. ⋯ This paper contributes with a measure that is both feasible to use in clinical practice and research, while being able to measure all facets of psychological flexibility and inflexibility-psychological processes of change that are important to evaluate in psychological treatment of chronic pain in order to better individualize treatment.
