Referred Pain Manifestation and Its Impact on Patients With Temporomandibular Disorder.

Objective: To investigate whether a higher number of sites eliciting referred pain upon palpation is associated with greater impairment in biopsychosocial aspects in TMD patients and identify variables that predict increased referred pain.

Methods: This cross-sectional study analyzed data from 77 women with myalgia, assessing the number of sites eliciting referred pain upon palpation in relation to clinical (duration, frequency, intensity, painful body sites, pain-related disability), psychological (stress, anxiety, depression, catastrophizing, sleep quality), and psychophysical variables (mechanical and pressure pain thresholds, temporal summation and conditioned pain modulation).

Results: Spearman's correlation revealed a significant correlation between the number of sites eliciting referred pain upon palpation in the orofacial region and both pain intensity and frequency (p < 0.

Interplay of Psychosocial, Clinical and Modulation Mechanisms in Chronic TMD-Related Disability.

Background: Temporomandibular disorder (TMD) is a multifactorial condition characterised by pain and functional impairment in the orofacial region. Although psychosocial and psychophysical factors significantly influence chronic pain, their combined impact on functional disability remains poorly understood.

Objectives: To investigate the influence of clinical, psychosocial and psychophysical variables on functional disability related to chronic pain in muscular TMD, utilising principal component analysis (PCA) and logistic regression.

Central sensitization inventory is associated with psychological functioning but not with psychophysical assessment of pain amplification.

Background: 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.

Influence of psychometric and sleep quality features on painful mechanical sensitivity and pain modulation in patients with temporomandibular disorders.

Unlabelled: Investigating the collective impact of psychometric properties and sleep quality on pain sensitivity in temporomandibular disorder (TMD) patients could improve clinical management strategies.

Objective: Assessing whether combined psychometric properties and sleep quality impact painful mechanical sensitivity and pain modulation in TMD patients.

Materials And Methods: A cross-sectional study using secondary data analysis of 77 TMD patients and 101 controls.
