“…In the control groups in the literature (10,11), the TPI treatment method was adopted, and the principle was to inject analgesic drugs (glucocorticoids and local anesthetics) into the trigger points to eliminate inflammation, block pain, and reduce edema. However, this treatment method lacks long-term effects, and the direct injection of drugs may bring allergic reactions and other adverse reactions (23). Extracorporeal shock waves do not require invasive procedures and directly conduct energy through the skin into muscle tissue to improve microcirculation and promote the separation of adherent soft tissues, which can have a long-acting analgesic effect (14).…”

Background: Myofascial pain syndrome (MPS) is recurrent local myofascial pain with various treatment methods. In recent years, extracorporeal shock wave therapy (ESWT) has attracted much attention, but its role still lacks systematic review. We included controlled clinical studies for meta-analysis to systematically evaluate the application effect of ESWT. Methods:The English literature from PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science to October 2021 was searched by computer. After screening, the quality was evaluated by the PEDro (Physiotherapy Evidence Database) scale and analyzed by RevMan 5.4 software.Results: A total of 571 patients were included in 8 studies. The MPS pain sites of 541 patients were in the neck and upper back, and only 30 patients had pain sites in the waist. Meta-analysis showed that the pain level after ESWT was lower than that after other treatment methods [mean difference (MD) =−1.34, 95% confidential interval (CI): −1.87 to −0.81, P<0.00001], the pain threshold after ESWT was higher than that after other treatment methods (MD =0.90, 95% CI: 0.73 to 1.07, P<0.00001), and the neck disability index after ESWT was lower (MD =−1.79, 95% CI: −2.48 to −1.10, P<0.00001).Discussion: ESWT can avoid the adverse effects of invasive procedures on patient tolerance and compliance; compared with trigger point injection (TPI), dry needling, ultrasound-guided pulsed radiofrequency (US), and other methods, ESWT can more effectively relieve pain in patients with MPS.

“…A baseline clinical examination was performed to determine if the pain was of joint or muscle origin. If it was muscle-derived pain, it was classified as localized or referred pain according to the DC/TMD classification [2,3], as (1) localized myalgia (LM): myogenic pain located in a hypersensitive nodule; (2) myofascial pain (MP): localized myalgia extending within the limits of the affected muscle; (3) referred pain (RP): when pain extends to areas outside the limits of the palpated muscle. In our cases, the palpation of an indurated and hypersensitive nodule, within a musculature of normal consistency, was the physical finding typically associated with a trigger point.…”

Botulinum toxin type A (BTA) injection is considered an available alternative treatment for myofascial pain. However, its efficacy in treating masticatory myofascial pain syndrome (MMPS) remains unclear. The purpose of this study was to evaluate whether the BTA injection into the affected muscles would significantly reduce pain and improve function, and to assess its efficacy, safety, and therapeutic indications in a randomized, single-center clinical trial. Sixty patients with MMPS were randomized into three groups evenly to receive a single session injection of saline solution (SS group), lidocaine (LD group), and BTA (BTA group) in the masseter, temporal, and pterygoid muscles after an electromyographic study. Patients’ pain was classified as localized or referred according to the DC/TMD classification. Assessments were performed on pre-treatment, and subsequently, on days 7, 14, 28, 60, 90, and 180. A significant reduction in pain and improvement of mandibular movements was found in the BTA group compared to the SS and LD groups. The response lasted until day 180 and was more intense in patients with localized myalgia and focused myofascial pain than in referred remote pain. No significant adverse reactions were observed. A single BTA injection can be considered an effective treatment option in patients with localized MMPS by reducing pain and improving mandibular movements, which persisted up to 6 months.

The evaluation of manual Trigger Point Therapy (TrPt) on mandible abduction range of Analog Astronauts (AA) surviving isolation conditions during consecutive missions at the LunAres Habitat was performed. This physiotherapy method was applied to decrease stress-related neuromuscular tension. Abduction measurements were conducted on the two groups of five AA, who endured severe isolation conditions for 14 days in the limited space of the LunAres Research Station Habitat (Piła, Poland) during missions. The test group consisted of abduction measurements of AA who received TrPt and control group of abduction measurements of AA who did not receive TrPt. All measurements were noted in the TemporoMandibular Joint (TMJ) diagnosis aspect of the integrated dental examination card SZOPPDP©. The ischemic compression was performed on an active localized trigger point—resulting in cessation of pain. Maximum abduction measurements were made with an electronic caliper, and the abduction range was compared. The change of abduction range in AA with TrPt was bigger than in AA without TrPt. A larger increase in abduction range was observed in every case in the group receiving TrPt compared to the control group. TrPt effectively decreases the neuromuscular tension, which results in an increased mandibular abduction range of AA. Observations conducted in LunAres Research Station regarding stress-related neuromuscular tension can help identify effective therapeutic methods for circumstances of social isolation.
