Background: The evaluation of muscle pain and sensitivity by manual palpation is an important part of the clinical examination in patients with myalgia. However, the effects of clinical experience and visual feedback on palpation of the masticatory muscles with or without a palpometer are not known.

Objective: To estimate the effects of clinical experience and visual feedback on the accuracy of palpation in standardized settings.

Objectives: This study aimed to determine if standardized palpations of the temporalis muscle evoke referred pain and/or sensations in individuals without TMD.

Materials And Methods: This was a randomized, single-blinded study. The mechanical sensitivity of the right temporalis muscle was assessed in 32 participants without TMD with nine different stimulations to 15 test sites using palpometers (different stimulus intensities (0.

Article Synopsis
  • - This study examined how healthy individuals react to pain in the skin over the masseter muscle, focusing on two groups: those prone to masseter pain (MPP) and those who are not (non-MPP), distinguished by their responses to a specific palpation test.
  • - Researchers conducted quantitative sensory testing (QST) to measure mechanical pain sensitivity and other pain thresholds, finding that the MPP group displayed higher pain sensitivity and lower pain thresholds compared to the non-MPP group.
  • - After applying lidocaine (an anesthetic), both groups showed no significant differences in pain sensitivity, indicating that the differences in pain perception were mainly linked to physiological responses rather than other factors.

Purpose: To investigate the effect of sleep restriction on somatosensory sensitivity related to occlusion.

Methods: Twelve healthy participants participated in an experimental voluntary total sleep restriction (SR) study. In a study design, they were invited to sleep as usual, normal sleep (NS) or to restrict their sleep for four nights.

Objectives: The aim of this study was to compare mechanical sensitivity on the tongue using quantitative sensory testing (QST) and psychological factors using the General Health Questionnaire (GHQ) between burning mouth syndrome (BMS) patients and healthy participants.

Materials And Methods: Participants comprised 20 female BMS patients (68.1 ± 7.

Aims: To determine if standardized palpation of the masseter muscle can evoke referred pain and/or sensations in healthy individuals and to compare the mechanical sensitivities in response to three different levels of palpation force.

Methods: A total of 32 pain-free individuals participated. The right masseter muscle was divided into 15 test sites.

This study investigated the effect of repeated tongue motor tasks on suprahyoid muscle activity and tongue pressure. Fourteen participants performed three series of a standardized tongue-lift training (TLT) task on each of five consecutive days. Electromyographic (EMG) activity from suprahyoid muscles and tongue pressure were recorded.

The aim of this study was to evaluate the relationship between pain intensities and psychosocial characteristics in middle-aged and older patients with temporomandibular disorders (TMDs) and burning mouth syndrome (BMS). Subjects were selected according to the Research Diagnostic Criteria for TMD (n = 705) and International Association for the Study of Pain criteria for BMS (n = 175). Patients were then divided into two age groups: 45-64 years (middle-aged, Group A) and 65-84 years (older, Group B).
