Summary: This study explored the relationship between acupuncture points and myofascial trigger points (TPs) and found that TPs are closely related to Ashi points. However, TPs also share some features with other acupuncture points, making it difficult to clarify their relationship with other subgroups.

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 considered data from 10 patients with non-specific chronic low back pain. The patients underwent six sessions of electrical neuromodulation applied to the areas of the skin with the most perturbed electrical conduction. The study observed improvements in the balance of electrical activity, temperature, disability caused by chronic low back pain, and pressure-pain threshold.

Summary: This article provides a scoping review of the current evidence on the mechanisms of intramuscular electrical stimulation (IMES) to trigger points (TrPs). The included studies suggest that IMES can regulate muscle blood flow, decrease endplate noise of TrPs, and produce analgesic effects. However, the limited amount and quality of available evidence make it difficult to determine the clinical implications of IMES to TrPs.

Summary: This study systematically reviewed literature on the objective characterization of myofascial pain syndrome and myofascial trigger points using imaging methods. The findings suggest that biomechanical properties and blood flow differences exist in active and latent myofascial trigger points compared to healthy tissue. More studies are needed to assess diagnostic test accuracy and reproducibility of results for implementing imaging methods in larger clinical studies.

Summary: Two individual case studies provide evidence that piezoelectric shockwave treatment is effective in improving tendon and muscle fiber patterns in canine patients with supraspinatus tendinopathy and supraspinatus and infraspinatus myofascial trigger points (MTPs), making it a viable option for the rehabilitation of common shoulder injuries in dogs.

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: The objective of this study was to evaluate the quality of evidence from randomized controlled trials on the effectiveness of manual trigger point therapy for orofacial pain. Four studies were included in this systematic review, and it was found that manual trigger point therapy was equally effective and safe for individuals with orofacial myofascial trigger points. However, the overall quality of evidence was found to be very low due to the high risk of bias in the included studies, and further well-designed trials are needed in this field.

Summary: This study aimed to verify the effectiveness of shock wave treatment for myofascial trigger points. The results showed that shock wave treatment eliminated the trigger points in mice muscles and reduced the frequency of neurotransmitter release, thus having a therapeutic effect.

Summary: This article introduces a new device that combines ultrasound and dry needling treatments. The non-thermal effects of ultrasound can amplify the effects of the needle by locally enhancing its effects. The ultrasound transducer can rotate in 3D space to align itself with the direction of the needle. The computer controls the angulation of the array and the focus position, allowing for electronic focusing of the acoustic pressure on the needle tip and its surroundings.

Summary: Myofascial pain syndrome (MPS) is a chronic pain disorder characterized by myofascial trigger points (MTrPs). This study found that MEF2C is involved in the inflammatory pathogenesis of MTrPs, and suggested that DEX may serve as a potential therapeutic strategy for MPS treatment.

Summary: This study found that a single session of dry needling can improve three viscoelastic parameters in the lateral gastrocnemius, decrease pressure pain sensitivity, but has no significant effect on strength and range of motion.

Summary: This research utilized thermal infrared imaging to study referred pain evocated by myofascial trigger points in the sternocleidomastoid muscle, finding that in 77% of cases, the referred pain area corresponded to a temperature change of ≥ 0.2 degrees Celsius. The study results suggest that thermal infrared imaging may be used to identify referred pain evocated by trigger points in the sternocleidomastoid muscle.

Summary: Cough variant asthma (CVA) is a chronic inflammatory airway disease characterized by airway hyper-responsiveness, with cough as the only symptom. This study investigated the efficacy and safety of latent MTrPs injection therapy in CVA, demonstrating that it provided long-lasting, practical, and safe treatment for CVA.

Summary: Using cell culture, this study examined the existence of contractile nodules on the taut band of muscle fibers where myofascial trigger points (MTrPs) are located. The results showed that MTrP cells can maintain contractile morphology in vitro, but the relationship between the recovery of such contractile nodules and acetylcholine remains uncertain.
