Rehabilitation of athletes’ after Achilles tendon surgery

Frequency of Achilles tendon injury increases. The lack of standardized methods of rehabilitation after surgery on the Achilles tendon leads to increased risk of repeated injury of tendon and reduces the possibility of coming round to physical activity. Recovery of function is the main task of rehabilitation programs, especially in athletes. This article sets out the basic principles of remedial actions. It can be used with patients of different levels of physical activity and it can be modified according to the task performed and features of surgical treatment in order to achieve optimal results

Chinese Historical and Ethnographic Monument “Images of Tributaries of the Ruling Qing Dynasty”: the Background to the Creation and Socio-Cultural Significance

The article is devoted to the study of Chinese historical and ethnographic monuments “Images of tributaries” (“Zhi gong tu”). One of them - “Images of tributaries of the ruling Qing dynasty” (“Huang Qing zhi gong tu”) is mostly analyzed. The novelty of the study is in the fact that for the first time in Russian science a comprehensive review and analytical consideration of these works is presented. The relevance of the study is caused by the growing scientific interest of Russian and foreign scientists in imagological research, as well as poor knowledge of these monuments. The article restores the historical background and circumstances of the creation of the album “Images of tributaries of the ruling Qing Dynasty”. The codicological and structural-compositional descriptions of two copies of it are kept in the collection of old-printed Chinese books of the Scientific Library of St. Petersburg State University. The classification of the regions and peoples described in the album is given. The method of organizing the material is analyzed. The nature of the information reported about ethnic groups is revealed. The question of the multi-level content of the book is raised, and the importance of its comprehensive study using interdisciplinary approaches is noted. Particular attention is paid to the connection of the monument with the traditional foreign policy concepts of imperial China; the unique features of “Huang Qing zhi gong tu” are revealed

Lateral epicondylitis: tendinitis or tendinosis?

Lateral epicondylitis is a common pathology of the musculoskeletal system resulting from repeated microtrauma of the extensor muscles of the forearm and their tendons. Lateral epicondylitis was previously thought to be tendinitis, which is an inflammatory reaction in the tendon. However, histopathologically, it has been shown to be low in inflammatory elements: macrophages and neutrophils. Thus, it is now believed that this pathology is a tendinosis, which is defined as a degenerative rather than an inflammatory process

The effectiveness of the use of various methods of shock wave therapy in the complex treatment of athletes with lateral epicondylitis

The purpose of the study: to evaluate the effectiveness of various methods of shock wave therapy in the complex treatment of athletes with lateral epicondylitis.Materials and methods: the study involved 122 people. with a diagnosis of Lateral epicondylitis, aged 20 to 45 years, of which 55 (45.1 %) women and 67 (54.9 %) men. All patients were divided into 4 groups: a control group, which included 28 people who underwent standard treatment, and 3 groups, a total of 94 people, who underwent shock wave procedures using various methods against the background of standard treatment. The examination included the collection of complaints, anamnesis, physical examination, assessment of the function of the upper limb using the QuickDASH questionnaire, assessment of tennis elbow using the PRTEE questionnaire, carpal dynamometry was performed on a MEGEON-34090 dynamometer, and statistical methods. All studies were conducted before, after treatment, as well as after 3 weeks and 1 month. after treatment.Results: shockwave therapy applied to tendons, flexors of the hand, and triceps brachii outperformed shockwaves to tendons or tendons and flexors of the hand in terms of Upper Limb Functional Activity (DASH) (p < 0,05) and score tennis elbow (PRTEE) (p < 0,05) after 3 weeks and after 1 month after treatment.Conclusion: reducing the severity of pain syndrome and functional disorders of the upper limb when performing various types of activities, when conducting shock wave therapy on the area of the tendons, flexor muscles of the hand and the triceps muscle of the shoulder indicates a faster recovery of the functions of the upper limb, which is especially important for athletes

Portable three-wavelength standard for energy unit of pulse laser radiation

New instrument for applications in metrological measurements of laser pulse energy is presented. Due to its parameters, it can be used as a standard for energy unit of pulse laser radiation. The instrument consists of a control unit, three different sources of laser radiation, two detectors of optical signal, and a laptop. The whole system can be easily transported enabling one to perform measurements in situ, at customers, and not only in laboratory conditions. A method of measurements used in the standard operation is described. Main characteristics of the standard are shown. Methods enabling calculations of measurement uncertainties during laser energy meter calibration by means of our standard are also presented

Shock wave therapy evaluation in the complex treatment of athletes with lateral epicondylitis

Objective: to evaluate the effectiveness of shock wave therapy in the complex treatment of athletes with lateral epicondylitis in comparison with standard methods of treatment.Materials and methods: On outpatient treatment in the period from 2019 to 2022. There were 168 athletes diagnosed with Lateral epicondylitis, including 78 women (46.4 %) and 90 men (53.6 %) aged 20 to 45 years. The mean age of the patients was 31.48 ± 6.72 years. The average duration of the disease was 33.68 ± 28.17 days. To achieve the set goals and objectives, a prospective randomized controlled clinical trial was conducted. We used a clinical examination of patients, a study of carpal dynamometry of the affected arm, an assessment of the level of pain and quality of life using the QuickDash and Patient-Rated Tennis Elbow Evaluation (PRTEE) scales, statistical research methods, as well as the use of standard treatment for lateral epicondylitis and radial shock wave therapy with an assessment of effectiveness one month after treatment.Results: shock wave therapy in the complex treatment of athletes with lateral epicondylitis, compared with standard methods of treatment, improved the quality of life and reduced pain three weeks after the start of treatment and has a more pronounced effect in the long term (p < 0.05); allowed to reduce the intensity of the signal from the bone tissue (trabecular edema) according to the results of magnetic resonance imaging.Conclusion: the expediency of using shock wave therapy in the complex treatment of athletes with lateral epicondylitis is substantiated, which makes it possible to recommend its use in practical healthcare
