Summary: This study investigated the condition of the upper trapezius muscle in patients with unilateral, more severe neck pain and found significant differences in stiffness on the same side. However, no differences were found in elasticity, cervical spine mobility, and pressure pain threshold.

Summary: The study aimed to analyze and compare the electromyographic patterns of masticatory muscles in subjects with active myofascial trigger points (MTrPs) within upper trapezius, patients with temporomandibular disorders (TMDs), and healthy adults. The results showed that both MTrPs in the upper trapezius and TMDs are associated with changes in electromyographic patterns of masticatory muscles.

Summary: This study evaluated the elasticity changes in the upper trapezius muscles of patients with cervical myofascial pain syndrome (MPS) using real-time ultrasound shear-wave elastography and examined their potential diagnostic value. The results showed that trapezius shear-wave velocity was significantly higher in MPS patients with moderate and severe pain compared to non-MPS patients. Therefore, trapezius shear-wave velocity may be valuable for the successful screening of cervical MPS, especially in patients with moderate and severe pain.

Summary: Real-time shear-wave elastography can evaluate the stiffness of trapezius muscles in patients with trapezius myofascial pain syndrome, and it has been found that the stiffness of both affected and non-affected trapezius muscles increases, with the degree of increase positively correlated with the time of cervical forward leaning.

Summary: This study investigated the physical and psychological factors contributing to pressure pain hypersensitivity in the upper trapezius, and found that in men, lower trapezius strength was the only significant influencing factor, while in women, dominant painful ipsilateral cervical rotation range of motion was the only influencing factor. Lower trapezius strength and dominant painful ipsilateral cervical rotation range of motion could be used as guidelines for preventing and managing pressure pain hypersensitivity in food service workers with nonspecific neck/shoulder myofascial pain.

Summary: This study found that a single session of DN or sham DN applied to active MTrPs located in the upper trapezius muscle produced no detectable changes in stiffness at the MTrP or control locations. Real DN induced an immediate analgesic response at both MTrP and control locations, while sham DN induced an immediate MTrP response.

Summary: The study recruited 63 female myofascial pain syndrome subjects and 20 healthy controls. The results showed that ultrasound texture features of blob size and count changed after conservative physical therapy, corresponding to improvements in pain ratings and disability scores. Cervical range of motion values were significantly increased at 3 months compared to pre-treatment, indicating the effectiveness of the therapy.

Summary: The study assessed the feasibility of using ultrasound texture features to evaluate changes after physical therapy in patients with myofascial pain syndrome. Results showed that changes in ultrasound blob size and count were related to reductions in pain and disability scores in female participants.

Summary: This study compared muscle recruitment patterns and muscle activity in individuals with and without chronic upper trapezius pain. The results showed that individuals with upper trapezius pain had increased relative contribution of the serratus anterior muscle activity and decreased middle deltoid activity at low loads.

Summary: This study examined the number and location of trigger points in police working dogs, finding a higher percentage of trigger points in the spinal and hind limb muscles, especially on the right side. These findings can help improve methods to prevent muscle pain and reduce early retirement in police working dogs.

Summary: This study aimed to compare the effects of Bowen therapy and tennis ball technique on pain and functional disability in patients with thoracic myofascial pain syndrome. The results showed that both treatments were significant, but Bowen therapy was more effective in reducing pain and improving functional disability.

Summary: Extracorporeal shock wave therapy (ESWT) has emerged as an alternative non-invasive treatment for musculoskeletal disorders, particularly myofascial pain syndrome (MPS). MPS, a common chronic painful condition, can be effectively treated with ESWT, which induces long-lasting analgesia.

Summary: This systematic review investigates the effectiveness of photobiomodulation therapy (PBMT) on pain and pressure pain threshold (PPT) in patients with myofascial pain syndrome (MPS) of the upper trapezius muscle. The results show that PBMT is effective in reducing pain and increasing PPT, especially when combined with exercise. However, the quality of the studies varies and more high-quality research is needed.

Summary: This study investigated the combined effects of radial shockwave and trigger point injection of lidocaine for upper trapezius myofascial pain syndrome. The results showed that the combined treatment was more effective in reducing pain and elastic stiffness compared to shockwave therapy alone.

Summary: This review provides a comprehensive summary on the symptomology, pathophysiology, and diagnostic and treatment methods of masticatory myofascial pain syndrome for endodontists. The most accepted diagnostic guidelines are the Diagnostic Criteria for Temporomandibular Disorders, although their diagnostic capability is limited. Treatment methods are individualized and multidisciplinary, focusing on muscle range of motion, deactivation of trigger points, and pain relief.
