There are many reasons for postural disorder development, but dysfunction of the cervical spine muscles is the most disputable reason. The purpose of the study is to reveal the influence of latent myogenic trigger zones of the cervical muscles on postural resistance. Materials and Methods. The authors used the method of computer posturography. Latent myogenic trigger zones (LMTZs) were determined by an indurated nodule or bundle in the neck muscle and by hyperesthesia in this zona. Assessment of postural resistance in subjects with LMTZs was carried out using standard posturography tests and Romberg test. Both classical and vector indicators were evaluated in a standard sample. Results. In fact, only vector indicators changed significantly in subjects with multiple LMTZs (4 or more). Thus, a decrease in the equilibrium function quality was established, as well as an increase in the average linear velocity of the pressure center and an increase in the normalized vectorogram area if compared with the indices in the control group and the group with sporadic LMTZs (from 1 to 3). The obtained results indicate a postural control decrease in individuals with multiple LMTZs. Subjects with sporadic LMTZs demonstrated a significant decrease in classical and a number of vector indicators, which shows the improvement in postural resistance in this test group. In Romberg test, all subjects with LMTZs, regardless of the zone number, showed an increasd Romberg coefficient. Conclusion. Multiple LMTZs of cervical muscles can reduce postural stability through increased afferentation from the cervical proprioreceptors. It is more obvious during in case of eye control elimination.

Выделяют множество причин развития постуральных нарушений, среди которых дисфункция мышц шейного отдела позвоночника является наиболее спорной. Цель исследования. Выявить влияние латентных миогенных триггерных зон шейной мускулатуры на постуральную устойчивость. Материалы и методы. Использовался метод компьютерной стабилографии. Латентные миогенные триггерные зоны (лМТЗ) определялись по наличию в мышце шеи уплотненного узелка или пучка и по повышенной болевой чувствительности в этой области. Оценка постуральной устойчивости у испытуемых с лМТЗ осуществлялась с помощью стандартного стабилографического тестирования и теста Ромберга. В стандартной пробе оценивались как классические, так и векторные показатели. Результаты. Показано, что у испытуемых с множественными лМТЗ (4 и более) достоверно изменяются только векторные показатели. Так, установлено снижение качества функции равновесия, а также повышение средней линейной скорости центра давления и увеличение нормированной площади векторограммы по сравнению показателями в группе контроля и группе с единичными лМТЗ (от 1 до 3), что указывает на снижение постурального контроля у лиц с множественными лМТЗ. У испытуемых с единичными лМТЗ отмечено достоверное снижение классических показателей и ряда векторных, что свидетельствует об улучшении постуральной устойчивости в данной группе испытуемых. В пробе Ромберга все субъекты с лМТЗ независимо от количества последних показали повышение коэффициента Ромберга. Выводы. Множественные лМТЗ шейной мускулатуры могут снизить постуральную устойчивость через усиление афферентации от шейных проприорецепторов, что наиболее выражено при элиминации зрительного контроля. Ключевые слова: латентные миогенные триггерные точки, постуральный контроль, стабилография, тест Ромберга.

Abstract Objectives Granisetron and lidocaine injections have been used for the management of myofascial pain syndrome. This study was aimed to compare the efficacy of granisetron and lidocaine injections to trigger points of upper trapezius in the management of myofascial pain syndrome. Methods We performed a double-blind randomized clinical trial in an outpatient clinic of physical medicine and rehabilitation at a teaching hospital. A total of 40 patients aged ≥18 with neck pain due to myofascial pain syndrome were included. They had pain for at least one month with the intensity of at least 30 mm on a 100 mm visual analog scale. Each participant received a single dose of 1 mL lidocaine 2% or 1 mg (in 1 mL) granisetron. The solutions were injected into a maximum of three trigger points of the upper trapezius. We instructed all patients to remain active while avoiding strenuous activity for three or four days, and to perform stretch exercise and massage of their upper trapezius muscles. We assessed the patients before the interventions, and one month and three months post-injection. The primary outcome was the Neck Disability Index and the secondary outcome was the Neck Pain and Disability Scale. Results Both interventions were successful in reducing neck pain and disability (all p-values <0.001). However, the neck pain and disability responded more favorably to lidocaine than granisetron (p=0.001 for Neck Disability Index, and p=0.006 for Neck Pain and Disability Scale). No significant side-effect was recognized for both groups. Conclusions Both lidocaine and granisetron injections to trigger points are effective and safe for the management of the syndrome and the benefits remain at least for three months. However, lidocaine is more effective in reducing pain and disability. The injections are well-tolerated, although a transient pain at the site of injections is a common complaint. One mL of lidocaine 2% is more effective than 1 mg (in 1 mL) granisetron for injecting into the trigger points of the upper trapezius in myofascial pain syndrome.

Two new chronic paroxysmal hemicrania patients are described. In both, attacks can be precipitated mechanically by applying firm manual pressure to certain sensitive points on the neck, i.e. in the C2 area, in the transverse processes of the C4–C5 vertebrae, or beneath the posterior part o15 the skull on the symptomatic side. The most sensitive area seems to be the transverse process of C4–C5. Susceptibility to this type of attack is dependent on the flow of spontaneous attacks; attacks are easily precipitated in a phase with multiple spontaneous attacks, but are not readily precipitated otherwise. Under indomethacin protection, local tenderness is clearly diminished and attacks cannot be precipitated.
