Craniosacral system and primary respiration in Chinese medicine
Authors: Akhmetsafin A. N. 
Published: February 2020

Introduction. Craniosacral technique and the concept of «primary respiration» is the most effective branch in modern osteopathy. Historically it goes back to the ideas of W. G. Sutherland, which was documented in the 1930s. However, when studying ancient documents of Traditional Chinese Medicine, some theoretical and technical details appear in the description of the craniosacral system. These details date back to the ancient period of the formation of the canon of Chinese medicine and are unknown to modern osteopaths.The goal of research — to clarify the historical priorities for describing the craniosacral system and its practical application in the clinical and hygienic aspect.Methods. We studied the canonical texts of traditional Chinese medicine and Taoism, related to clinical and hygienic manipulations and life extension practices. Authentic epigraphic material with a detailed etymological analysis of ancient hieroglyphs was used in order to determine the anatomical, physiological and clinical views of the ancient people.Results. The mention of the main elements of the craniosacral system and the description of technical procedures date back to the formation of the medical canon, i. e. before the 3rd century B. C. Real anatomical ideas about the structure and functioning of the skull, spine and sacrococcygeal complex, as well as a detailed description of «primary respiration» are documented in the medical and Taoist canons.Conclusion. Studying the canonical texts of Traditional Chinese Medicine and Taoist sources basing on the practice «Nourishing Life» can significantly enrich the «toolkit» of modern osteopathy.

Published: February 2020

Introduction. Degenerative-dystrophic lesion of the spinal joints or spondylarthrosis is one of the most common diseases of the spine. The signs of non-infl ammatory changes in the joints can be detected even in children. The reason for this is the repetitive biomechanical microtrauma. The goal of research — to study the frequency of degenerative-dystrophic lesions of the spinal joints at all the levels in young and middle-aged patients suffering from dorsopathy.Materials and methods. Radiography of all the regions of the spine was performed with the description of system models of 507 patients: 211 men and 296 women, suffering from dorsopathy. The method of integral study of the spine roentgenograms was used. Systemic models of patients with determined diagnosis of ankylosing spondylitis (Bekhterev disease) were excluded from the general population. The reason for this was a signifi cant morphological change in the joints and in the spinal column as a whole, due to chronic infl ammation, which is the main manifestation of this disease. Statistical processing was carried out using Microsoft Offi ce Excel 2007.Results. It was established that with age the frequency of appearance of radiological signs of spondylarthrosis increases. Signs of arthrosis of the zygapophyseal joints appear in the fi rst turn and are the most frequent ones. Arthrosis of the zygapophyseal joints is diagnosed in 70–90 % of patients. Spondylarthrosis of the semilunar joints is diagnosed in almost 80 % of patients. Most often arthrosis of the semilunar joints was observed in the vertebrae CV and CVI. Athrosis of costovertebral joints was registered in 32,7 % of patients. In most cases the joints TVII–TX were affected by this disease. Arthrosis of the sacroiliac joints was diagnosed in an average of 63,8 % of patients, equally often on the left and on the right sides. The interspinal neoarthrosis (Baastrup symptom) was diagnosed at the level of LIII–LV(VI) in 22,6 % of patients and at the level of CI–CII in 2 % of patients.Conclusion. Radiological manifestations of spondylarthrosis are markers of static and dynamic biomechanical overload of the spinal joints.

Published: February 2020

Introduction. Low back pain takes one of the leading places among all non-communicable diseases, reaching 70 % of outpatient visits. In 90 % of cases the non-specific nature of back pain is observed. The most common causes of low back pain are myofascial pain syndrome, facet joint arthrosis, spinal stenosis, spondylolisthesis, discal hernias. If NSAIDs and muscle relaxants are the «gold standard» in the treatment of low back pain, interventional treatment needs further studies. This trial was conducted in order to determine the effectiveness of therapeutic blockades. The goal of research — to study the effectiveness of selective injections of pharmaceuticals into pain sources in case of low back pain based on clinical and instrumental studies.Materials and methods. The prospective, controlled, randomized trial was conducted from January 2018 to January 2019 at the Department of Neurosurgery and Medical Rehabilitation of the Bashkir State Medical University. 42 patients with low back pain, aged from 24 to 54 years, of which 28 (66,7 %) were men and 14 (33,3 %) were women took part in the research and were randomly divided into 2 groups. Patients of the main group (30 people) underwent interventional therapy, from 2 to 7 injections, depending on the severity of the pain syndrome and the duration of the disease. Patients of the control group — 12 people, received treatment in accordance with the standard of medical care in low back pain (analgesics, NSAIDs, muscle relaxants), as well as physiotherapy for 2 weeks daily. The study of the effectiveness of therapy included, along with the neurological examination, a neuroorthopedic instrumental examination. The depth of the lumbar lordosis, flexion and extension restrictions were measured using a curvimeter-goniometer, which also allows measuring the angle of tension symptoms (Lasegue, Wasserman). In order to study rotation and lateroflexion, instruments with a graduated scale were used. Muscle tone and tenderness of the structures of the spine were examined using a myotonometer-tensoalgimeter and a visual analogue scale (VAS). To interpret the data of a comprehensive neuroorthopedic examination, the results were converted into comparable units with the calculation of the integral indicator.Results. After selective intervention therapy in the main group, a more rapid relief of pain, a regression of neurological symptoms, manifested by the complete elimination or significant reduction of biomechanical and tonus disorders in the lower back were noted.Conclusion. Selective injections of pharmaceuticals into pain sources in low back pain are more effective than treatment with the use of analgesics, NSAIDs, muscle relaxants and physiotherapy, which allows to recommend them for wider use in clinical practice.

Published: February 2020

Para la reutilización de los neumáticos de vehículos, se presenta un proceso llamado trituración, el cual permite reciclar y aprovechar los distintos materiales para uso de diversas aplicaciones industriales. El diseño básico del sistema de trituración de neumáticos mediante cuchillas eficientes fue considerado como alternativa de solución a la problemática de varios sectores empresariales, que aún no han reutilizado el material. El objetivo de la investigación persigue el diseño y selección de cuchillas para el proceso de trituración de neumáticos y análisis de costos de fabricación. Por consiguiente, se analizaron propiedades mecánicas típicas del caucho en el proceso de corte, y fueron comparadas las alternativas económicas de cuchillas para el establecimiento de un proceso adecuado de trituración de neumáticos. Cada una de las alternativas comparadas difiere en características mecánicas y naturaleza del material muy difundidos en el medio local como el caso de ASTM- A36, SAE -1045, y SAE- S1, siendo el primer material el más económico y recomendado, siempre y cuando se utilice la alternativa de diseño según el modelo de flancos curvos, con deformación máxima en promedio de 0.0202mm. Se concluye con un costo de fabricación bajo independientemente que varíe el diseño de la cuchilla, en todo caso se debe realizar tratamiento térmico. El sistema de trituración fue dimensionado de tal manera que se traten neumáticos desalambrados, típicos en vehículos pequeños, por ser muy numerosos ya que existen menos casos de reencauche. La investigación se convierte en una alternativa sustentable y factible para la industria mediana y pequeña que tiene a bien ofertar productos a base de material reciclado como el caucho.
