Chronic pain (CP) is a major public health problem affecting patients' lives and reducing physical activity. The aim is to establish subgroups of people with chronic pain (PCP) according to limitations in activities of daily living (ADLs), and to identify sociodemographic, pain-related, and psychosocial variables associated with each subgroup. ⋯ The identification of the characteristics of people with higher limitations could help guide future prevention and treatment initiatives to minimize the disabling impact of chronic pain on patients' family, work, and social life.

The fascia is an undifferentiated mesenchymal tissue related to the peripheral nerves. Both can be identified by ultrasound, which is useful when performing peripheral nerve blocks. However, there is no unanimity about the approaching point of each nerve, nor is there a consensus on how to name the appropriate infiltration zone, although the paraneural zone is frequently mentioned. ⋯ Nerves of the knee were injected with colorant guided by ultrasound after they were visualized. Correct location of the nerves by ultrasound was achieved in 98.75% of the cases, correct visualization of the needle by ultrasound in 82.5%, the hypoechogenic image around the nerve after infiltration in 82.5%, and a correct paraneural infiltration in 76.25% of cases. With these results, we can conclude that high-definition ultrasound enables location of the peripheral nerves and adjacent structures as well as the fasciae that surround them, and therefore allows performance of infiltrations in the paraneural spaces.

Recent studies support the opinion that central sensitization (CS) plays an important role in the pathophysiology of many chronic pain conditions. CS refers to hyperexcitability of the central nervous system, which can result in pain hypersensitivity and other somatosensory symptoms. Recognition of CS-related symptomology is crucial in chronic pain evaluation and rehabilitation. The Central Sensitization Inventory (CSI) was created to evaluate symptoms that have been found to be associated with CS. The aim of the current study was the cross-cultural adaptation of the CSI into Greek (CSI-Gr). ⋯ As determined in the present study, the CSI-Gr was found to be a reliable and valid tool for recognition of CS-related symptomology.
