Background Myofascial pain syndrome (MPS) is an important clinical condition that is characterized by chronic muscle pain and a myofascial trigger point (MTrP) located in a taut band (TB). Previous studies showed that EphrinB1 was involved in the regulation of pathological pain via EphB1 signalling, but whether EphrinB1-EphB1 plays a role in MTrP is not clear. Methods The present study analysed the levels of p-EphB1/p-EphB2/p-EphB3 in biopsies of MTrPs in the trapezius muscle of 11 MPS patients and seven healthy controls using a protein microarray kit. EphrinB1-Fc was injected intramuscularly to detect EphrinB1s/EphB1s signalling in peripheral sensitization. We applied a blunt strike to the left gastrocnemius muscles (GM) and eccentric exercise for 8 weeks with 4 weeks of recovery to analyse the function of EphrinB1/EphB1 in the muscle pain model. Results P-EphB1, p-EphB2, and p-EphB3 expression was highly increased in human muscles with MTrPs compared to healthy muscle. EphB1 (r = 0.723, n = 11, P < 0.05), EphB2 (r = 0.610, n = 11, P < 0.05), and EphB3 levels (r = 0.670, n = 11, P < 0.05) in the MPS group were significantly correlated with the numerical rating scale (NRS) in the MTrPs. Intramuscular injection of EphrinB1-Fc produces hyperalgesia, which can be partially prevented by pre-treatment with EphB1-Fc. The p-EphB1 contents in MTrPs of MPS animals were significantly higher than that among control animals (P < 0.01). Intramuscular administration of the EphB1 inhibitor EphB1-Fr significantly suppressed mechanical hyperalgesia. Conclusions The present study showed that the increased expression of p-EphB1/p-EphB2/p-EphB3 was related to MTrPs in patients with MPS. This report is the first study to examine the function of EphrinB1-EphB1 signalling in primary muscle afferent neurons in MPS patients and a rat animal model. This pathway may be one of the most important and promising targets for MPS.

Цель. Оценить эффективность инъекций в триггерные точки при лечении миофасциального болевого синдрома челюстно-лицевой области. Материал и методы. С 2014-2017 гг. было пролечено 124 человека с миофасциальным болевым синдромом лица, из них 76 женщин и 48 мужчин в возрасте от 19 до 62 лет. Кроме клинических и рентгенологических методов диагностики всем пациентам выполняли электромиографию и тестирование болей по визуальной аналоговой шкале боли (VAS). С целью купирования миофасциального болевого синдрома применялись методы традиционной терапии: шиновая терапия, коррекция окклюзии, медикаментозная и физиотерапия. При неэффективности традиционных методов выполнялись инъекции «Лимфомиозот» и «Траумель С» в триггерные точки по методике J. Kersschot (2010). Контрольные осмотры проводились через 1, 3, 6, 12 и 18 и 24 месяца после выполнения манипуляции. При контрольных осмотрах обращали внимание на жалобы пациентов, определяли интенсивность боли по VAS. Критерием положительных результатов лечения являлось отсутствие болей в покое и при функциях. Результаты. При стандартном лечении положительные результаты были получены у 86 из 124 человек (69,4%). Инъекции в триггерные точки, выполняемые при недостаточной эффективности лечения у 38 человек, привели к прекращению боли у 32 (84,2%) пациентов. Как показали наши наблюдения, длительный период без боли (в течение двух лет) наблюдали у 12 (37,6%) человек. Продолжительный эффект в течение периода времени до полутора лет был констатирован у 8 пациентов (25%), до 1 года – у 7 человек (21,8%), до 6 месяцев – у 5 (15,6%). Заключение. Инъекции в триггерные точки повышают эффективность терапии и обеспечивают длительный период ремиссии заболевания, что проявляется в отсутствии болевых приступов и ощущения дискомфорта. Научная новизна статьи Впервые для лечения миофасциального болевого синдрома (МБС) лица была использована методика с применением инъекций «Лимфомиозот» и «Траумель С» в триггерные точки. Установлено, что данная методика инъекций в триггерные точки является эффективным методом лечения МБС лица в независимости от причины, его вызвавшей. Показано, что применение инъекций в триггерные точки при миофасциальном болевом синдроме лица способствовало быстрому купированию болей и длительному безболевому периоду сроком наблюдения до двух лет.

Background: Myofascial pain syndrome is a chronic syndrome that occurred in a local or focal part of the body. The basis for myofascial pain syndrome is the presence of myofascial trigger point or points, producing pain in clinical examinations. Objectives: This study aimed to compare the effect of injection of bicarbonate, hyaluronidase, and lidocaine on myofascial pain syndrome. Methods: The patients were randomly allocated to three groups of bicarbonate, hyaluronidase, and lidocaine. The injection was done at two painful regions of trapezius muscle with a sonography guide for each patient. The values of visual analogue scale (VAS), pre-injection range of motion (ROM), immediately after injection, second and fourth week were measured. Results: The analysis showed that there were no significant differences between the three groups for age, gender, BMI, and height (P > 0.05). Repeated measures one-way ANOVA (week * group) 4 * 3 was used to compare the effect of bicarbonate, hyaluronidase, and lidocaine on VAS and range of motion (ROM) before injection, immediately after injection, second and fourth week. The results showed that the main effect of group and week is significant for VAS (P < 0.05). This study showed that the values of VAS were significantly different between the three groups during the fourth weeks of the study. Moreover, the patients experienced more pain decline in the hyaluronidase group during weeks before injection, after injection, second and fourth week, which indicated the permanent effect of this medication on pain decline. Conclusions: Injection of lidocaine leads to a significant reduction in pain immediately after injection; however, the decline was not permanent and disappeared in the following four weeks. But VAS reduction in hyaluronidase group more than bicarbonate and lidocaine groups.

Abstract Background Myofascial pain syndrome is one of the commonest pain syndromes now a days. Its pathophysiology is not fully documented or understood. Goal of treatment is to release the pain and discomfort of myofascial pain syndrome. Methods This was a multicentric prospective study comprising 70 patients who had been diagnosed clinically with myofascial pain syndrome in the neck, shoulder or back. Cases were randomly divided into two treatment groups. First group (36 cases) were treated with physiotherapy modalities (extracorporeal shock wave therapy and ultrasound therapy as combination therapy) and patients in second group (34 cases) were treated with trigger point injection. In both the groups patients were advised stretching exercises as soon as pain decreases. Results Pain was substantially decreased in both the treatment groups but results were early and comparatively better in patients treated by trigger point injection group. Stretching exercises were helpful in regaining strength and also helpful in decreasing recurrence of pain.

Myofascial pain syndrome is a common problem that can develop at any age. This study compares the efficacy of the court-type traditional Thai massage (CTTM) to the Thai hermit exercise (THE) in improving the cervical range of motion (CROM) and reducing pain in the upper trapezius muscle. In this study, 46 patient subjects were randomized into 2 groups, with 1 group administered CTTM and the other administered THE. Prior to and following the experiment, their demographic characteristics, pain levels and CROM were measured using a visual analog scale (VAS) and a goniometer, respectively. Data was then analyzed using descriptive statistics, percentage, mean, and standard deviation, as well as inferential statistics. The findings indicate that subjects in both groups demonstrated significantly lower pain and significantly better CROM (P < 0.05). In terms of comparative treatment between the CTTM and THE groups, the results were not found to differ in the range of motion, but a clear difference in pain level measured by VAS was found, in which CTTM provides a better way of reducing pain at the trigger point than THE (P < 0.05). From the findings, it can be concluded that both CTTM and THE are comparably efficacious therapies for myofascial pain in the upper trapezius muscle.
