Despite the use of Patient-Drawn Pain Drawings (PDPDs) in clinical settings, their validity as indicators of psychological distress remains debated. We aimed to assess the association between PDPD areas and physical health and psychological variables. ⋯ This large-scale study demonstrates that extensive pain areas in pain drawings drawn by LBP patients do not signify psychological distress. Our findings reveal that these pain representations are more closely linked to increased pain intensity, pain duration, and disability rather than being independently associated with psychological factors. Clinicians are encouraged to focus on the association of extensive pain areas with physical symptoms rather than psychological distress during clinical assessments.

Randomized Controlled Trial
The Effects of Virtual Reality Application on Pain Intensity, Anxiety Level and Patient Satisfaction in Patients Who Undergo Bronchoscopy: A Randomized Controlled Trial.
Bronchoscopy is a medical procedure that allows imaging of the airways and lungs. With the help of a light and camera at its tip, the bronchoscope device can enter the airway and provide real-time visualization. Since most patients are conscious during the bronchoscopy procedure, they may experience pain and anxiety regarding possible complications and an uncertain outcome. ⋯ Study results for this sample revealed that the use of VR decreased pain intensity scores, state anxiety levels, anxiety severity, diastolic blood pressure, systolic blood pressure, heart rate and respiratory rate, and increased O2 saturation in patients who underwent bronchoscopy. In line with these results, VR should be considered during bronchoscopy procedures.

Interhemispheric and Corticothalamic White-Matter Dysfunction Underlies Affective Morbidity and Impaired Pain Modulation in Chronic Pain.
Although patients with chronic pain show behavioral signs of impaired endogenous pain modulation, responsible cerebral networks have yet to be anatomically delineated. We used diffusion tensor imaging (DTI) to examine the white-matter alterations in patients with chronic pain compared with healthy subjects. We further measured thermal pain modulatory responses using the offset analgesia (OA) paradigm. We tested whether the white-matter indices be associated with psychophysical parameters reflecting morbidity and modulatory responses of pain in patients, and whether they could serve as diagnostic biomarkers of chronic pain. ⋯ Patients with chronic pain showed dysfunction of the white matter concerned with interhemispheric communication of sensorimotor information as well as descending corticothalamic modulation of pain in association with affective morbidity and altered temporal dynamics of pain perception. We suggest that an impaired interhemispheric modulation of pain, through the corpus callosum, might be a novel cerebral mechanism in chronification of pain.

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.

Comparative Study Observational Study
Comparison of trunk muscle endurance between women with and without chronic neck pain.
To compare trunk flexor, extensor, and lateral flexor muscle endurance between women with moderate to severe disability due to chronic neck pain (CNP) and asymptomatic women. ⋯ The findings of reduced endurance in trunk muscles should be considered when incorporating interventions in the management of CNP to effectively address pain and disability.
