Переміжна пневматична компресія у реабілітаційній та спортивній медицині

The purpose of the study was to characterize the clinical value of intermittent pneumatic compression in sports medicine according to the scientific literature. Materials and methods. The English-language publications refereed by the PubMed electronic database, by the keyword “intermittent pneumatic compression”, concerning sports achievements, physiology of athletes, sports rehabilitation and also the treatment of injuries were analyzed. Results and discussion. Hardware for intermittent pneumatic compression develops rapidly in sports rehabilitation, while a significant number of practitioners use intermittent pneumatic compression in combination with other means, which makes it difficult to assess its effectiveness. Traumatic risk is a reality of the professional activity of athletes. In several reviews of the literature, it was shown that the use of intermittent pneumatic compression after injuries can reduce thrombus formation, swelling and duration of preoperative preparation for fractures, reduce swelling and improve joint mobility after fractures, improve wound and fracture healing. During the rehabilitation period, intermittent pneumatic compression allows to reduce limb dysfunction after sprain, increase joint mobility, and enhance the effectiveness of occupational therapy measures. Conclusion. Skeletal muscles are undoubtedly the target organ of intermittent pneumatic compression, but the optimal parameters of exposure need to be clarified. During exercise, intermittent pneumatic compression improves vascular conductivity, and during the recovery period it reduces muscle proteolysis, increases blood flow and tissue oxygenation. Intermittent pneumatic compression does not appear to affect muscle strength and performance recovery. Intermittent pneumatic compression may help reduce delayed muscle pain syndrome, but the optimal conditions for such an effect need to be investigated. In trauma, in particular sprains and fractures, the use of intermittent pneumatic compression can reduce pain and the need for narcotic analgesics, especially in the early stages. The use of intermittent pneumatic compression can reduce swelling and shorten the duration of preoperative preparation for fractures, subsequently improving joint mobility, wound and fracture healing. After surgery or removal of immobilizers, intermittent pneumatic compression reduces swelling, improves limb function, and reduces hospital stay. When using intermittent pneumatic compression in work with athletes, the practitioner must also take into account its reparative, adaptive and other general effects. Intermittent pneumatic compression is a promising sports medicine tool, but the existing data are completely insufficient to make firm recommendations

Sports Rehabilitation Base in Natural Environment Helps College Students' Psychological Anxiety

For the growing number of college students with anxiety, how to help college students control anxiety or cope with anxiety has become the focus of social and mental health research. Through the questionnaire data on college students' anxiety factors and the analysis of the treatment methods for the corresponding symptoms in China, we can learn that there are some drawbacks in the common anxiety symptoms of college students and the existing treatment methods for middle and low levels of psychological anxiety in China. Therefore, based on the results of relevant papers, our team summarized several relevant research on treatment methods, synthesized two more effective treatment methods, put forward the idea of "setting up a base in an outdoor natural environment, and then carrying out aerobic exercise", and established the feasibility of Huaiyuan County's environment through the evaluation of relevant indicators and the field survey of the scheduled treatment sites, It also predicts that aerobic exercise in the base set up in the outdoor natural environment has practical effect on the treatment of psychological anxiety.

Evaluation of recurrent soft tissue injuries of shoulder after physiotherapy treatment in athletes

Traumatic injuries to the soft tissues of the shoulder are a common cause of shoulder pain and dysfunction in athletes. These injuries have a serious impact on the athlete's work capacity and quality of life, which often causes athletes to withdraw from training and competition. Taking into account modern requirements, a long break in sports activities is almost impossible, because in the majority of cases, the last mentioned is equivalent to the end of the professional career. It should be noted that after conservative treatment of soft tissue injuries of the shoulder (tendinitis of the long head of the biceps muscle, partial damage to the structures of the rotator cuff, glenoid labrum) repeated injuries and relapses often occur, which makes it even more difficult to fully restore the athlete's shoulder function and the athlete's withdrawal from the training process is longer. The purpose of the study is to find the incidence of repeated injuries and pain recurrences in athletes after physical therapy treatment of shoulder soft tissue injuries. The present study involves a quantitative and qualitative evaluation of the emergence of pain reactivity after physical therapy treatment of soft tissue injuries of the shoulder in athletes, 8 and 12 weeks after the athletes' return to normal activity. Monitoring was carried out on 52 athletes at the Sports Medicine and Rehabilitation Clinical Center of TSMU. The average age of the athletes was 23 ± 2 years. Athletes participating in the study were randomly divided into three groups: I main, II and III control groups and appropriate rehabilitation interventions were implemented. In all three groups of patients participating in the study, after 8 and 12 weeks, the occurrence of shoulder function limitation and pain were studied using the PSS (The Penn Shoulder Score), SSPS (Subjective Sport Performance Satisfaction) and the Kerlan-Jobe Shoulder and Elbow Clinical Orthopedic Clinical Scales. Based on the data obtained from the study, 8 weeks after the start of sports activity of 52 athletes, cases of early repeated injuries were detected in 35 percent of athletes, and after 12 weeks, cases of late repeated injuries were observed in 25 percent of the remaining 34 athletes. 8 weeks after the start of sports activity in 52 athletes, 18 cases of recurrent early injury were noted, in the remaining 34 athletes, after 12 weeks, recurrent late injuries were identified in 8 athletes. The study includes evaluation and comparative analysis of repeated injuries in groups I-II and I-III after 8 and 12 weeks of participation in sports activities by means of the specified scales. The study revealed that treatment with combined physical agents significantly reduced the incidence of repetitive injuries in athletes and also demonstrated a significantly lower recurrence rate of emerging pain, thereby optimizing the athlete's performance.

Adherence to exercise and fitness following exercise-based outpatient cardiac rehabilitation: a cross-sectional survey for Germany

BackgroundExercise-based cardiac rehabilitation is safe and effective, evidence-based and implemented in national and international cardiac rehabilitation guidelines. Recent data show a decrease in cardiovascular mortality, reduced hospital admissions and an overall improvement in quality of life. To maintain positive effects and to prevent further cardiovascular events a major goal of cardiac rehabilitation is to induce a long-term health behaviour change and the integration of regular physical activity and exercise training in everyday life. The aim of this study is to evaluate the adherence of cardiac patients to exercise-based programs following rehabilitation phase III.MethodsA nationwide online cross-sectional survey was conducted. All outpatient aftercare providers who offer sports rehabilitation programs (heart groups) for cardiac patients in Germany were contacted. The questionnaire comprised 15 questions in five subcategories (general information regarding the outpatient aftercare provider, structure of rehabilitation sport programs, membership structure, content of heart groups, adherence to exercise-based programs).Results560 of 2447 outpatient aftercare providers participated in the survey (response rate: 23%). On average, rehabilitation sport facilities hosted 2 (IQR 2) heart groups per week, and 23 patients (IQR 30) (61% males; 31% females) per facility completed rehabilitation sport prescription in 2018. Almost all providers offer follow-up programs on a self-payer basis after rehabilitation sport prescription ends. Adherence to follow-up programs was at 54% (IQR 65; 55% males and 50% females). With 60% (IQR 71), patients with a statutory health insurance (mainly pensioners) adhere slightly more often to a follow-up program compared to privately insured persons (mainly population with a high income or civil servants) with 50% and significantly more often compared to persons who were insured by the German pension fund (covering working population) with only 9% (IQR 89) adherence.ConclusionAlmost all outpatient aftercare providers offer follow-up programs for cardiac rehabilitation patients but only half of them actually participate. Younger people (working population) do not adhere sufficiently to sport and exercise programs following rehabilitation phase III. This seems critical to address in terms of achieving long-term rehabilitation goals.

APLICAÇÃO DE TREINAMENTO FÍSICO EM CONJUNTO À REABILITAÇÃO DE LESÕES NO FUTEBOL MASCULINO

ABSTRACT Introduction: Soccer is one of the sports with the highest incidence of injuries, generated both by the high performance required on the field and by physical conflicts between players. A fast rehabilitation is essential for the player’s performance. It has been empirically observed that an early recovery in patients’ rehabilitation is associated with physical training compared to players who received only the traditional rehabilitation. Objective: Verify the physical training influence on rehabilitation sports injuries in male soccer players. Method: 180 cases of male adolescents with sports injuries admitted to a Taiyuan hospital were selected. A division into two groups was randomly computerized to avoid statistical differences in the intensity of the injuries. The control group (14.3±2.45 years old) was treated with the standard protocol, while the experimental group (15.3±2.95 years old) received an intervention with physical training. Interviews and questionnaires were conducted involving analysis of time and severity of the injury, laterality, and location. The control group received treatment based on this information. The recovery rate and intervention satisfaction rate were collected. SPSS22.0 Statistical Software was used for student’s t-test and chi-square test. Results: Treatment efficiency was 82 (91.11%) in the control group versus 88 (97.78%) in the experimental group. The degree of dissatisfaction was 1 (2.11%) versus 8 (10%). The perceived overall satisfaction was 80 (89%) versus 87 (96.67%), (p <0.05). Conclusion: Rehabilitation associated with physical training intervention improved satisfaction and treatment efficiency. Evidence Level II; Therapeutic Studies – Investigating the results.

382 Essential Skills for Future Equine Sports Rehabilitation Careers

Abstract The field of equine sports medicine and rehabilitation is rapidly expanding with increasing career opportunities for individuals (non-veterinarians) in equine rehabilitation facilities. However, throughout the United States, there are limited educational opportunities for undergraduate students to prepare for this career. The objective of this study was to determine what practical skills and theoretical knowledge are deemed most useful for employment by professionals in this industry. To meet this objective, an Qualtrics survey was distributed through email and social media to veterinarians, veterinary professionals, rehabilitation service providers, and horse owners. In addition to demographics, the survey asked respondents to list practical skills and theoretical knowledge that are essential for professionals in the equine rehabilitation industry. The majority of the 117 respondents (84%) were located in the United States, with the remainder from Canada (5%), the United Kingdom (5%) and several other countries. Eighteen percent of respondents were veterinarians, 26% owned or managed rehabilitation facilities, 8.5% were veterinary technicians, and the remainder were horse owners, rehabilitation service providers, and others. Horse handling skills (19%) and communication skills (18%) were the most commonly listed practical skills deemed essential for rehabilitation professionals. Of the theoretical skills, evaluation of lameness (29.5%), anatomy (31%), and fundamentals of equine reconditioning programs (32%) were deemed similarly important for rehabilitation professionals. Together, these data indicate that an educational program in equine sports rehabilitation should include fundamental knowledge in lameness evaluation and rehabilitation methods as well as significant hands-on opportunities with rehabilitating horses and communicating about rehabilitation methods and progress with clients.

Construction of Sports Rehabilitation Training Method Based on Virtual Reality

The introduction of virtual reality technology into rehabilitation training can avoid various shortcomings of traditional rehabilitation training, and can efficiently complete training tasks. Based on the basic theory of virtual reality, this paper constructs a sports rehabilitation training method to achieve the consistency of the virtual upper limbs and the real upper limbs of the human body. The model provides a background environment in the virtual reality training, realizes the systematic maintenance of the patient’s training mode, provides the patient with a scientifically based training mode and evaluation results, solves the quantitative index problem of sports rehabilitation training, and builds a virtual upper limb platform at the same time. During the simulation process, the system used the Berg balance assessment scores to conduct four-stage assessments. Before treatment, the three-dimensional gait analysis, FMAL lower extremity function scores and Berg balance assessment results were not significantly different between the control group and the experimental group ([Formula: see text]). The experimental results showed that the three-dimensional gait analysis was used to analyze the pace, left and right step length, left and right support percentage, and stride frequency. Compared with the evaluation data before treatment, the index values of the control group and the experimental group were significantly improved ([Formula: see text]); after the treatment, the two groups of patients were evaluated for motor function, the evaluation values of the experimental group were higher than those of the control group when compared between the two groups. It effectively meets the human–computer interaction needs of rehabilitation training.

Core muscle strength can be reliably measured using a novel isokinetic device: An intra-observer study.

BACKGROUND: Core strength is an important aspect of physical fitness. A dynamometer was developed to measure isokinetic core muscle strength in multiple planes of motion. Establishing the reliability is needed before it can be used in practice.OBJECTIVE: Examine the intra-observer reliability of a trunk isokinetic dynamometer.METHODS: 31 participants were recruited. Tests were performed twice with an interval of 5–9 days by the same observer. Testing included rotation, flexion/extension and lateral flexion at speeds of 90/s and 60/s. The main outcome measure was peak torque (PT). The secondary outcomes included peak torque angle (PTA), time to peak torque (TTPT) and compensatory torques (CompTQ). The intra-observer reliability was investigated using intraclass correlation coefficients (ICC).RESULTS:Peak torque reliability was good to excellent (ICC 0.70–0.91), whereas the reliability of the PTA (ICC 0.04–0.56) and TTPT (ICC 0.01–0.68) were poor to moderate. CompTQ reliability was moderate to good (ICC 0.20–0.88).CONCLUSIONS: The intra-observer reliability of the isokinetic measurement of core strength peak torque was good. The secondary outcomes peak torque angle and time to peak torque were less reliable and the compensatory torques showed moderate to good reliability. This isokinetic dynamometer could have useful applications in the field of sports medicine and rehabilitation.

Barometric and Spatiotemporal Gait Differences Between Leading and Nonleading Feet of Handball Players

Side-to-side stress imbalance has been suggested as a risk factor for injury in unilateral sports. The leading leg is suggested to be essential in sports rehabilitation for the return of athletes to the playground. The main aim of this study was to evaluate the dynamic pedobarometric and spatiotemporal gait differences between the leading and nonleading feet of male handball players. Thirty healthy elite male handball players (mean ± SD: age, 31.7 ± 2.99 years; height, 177.5 ± 6.0 cm; weight, 78.9 ± 6.3 kg; body mass index, 25.0 ± 0.7) participated in this study; all of the participants were backcourt and pivot handball players. The assessments were performed using the Tekscan Walkway pressure sensor to detect and compare the variables of interest between the leading and nonleading feet during normal walking at a self-selected speed. Maximum force, peak pressure (total and forefoot pressure), foot width, single-limb support time, and step velocity were significantly increased in the leading foot compared with the nonleading foot. In addition, maximum force, foot width, and total peak pressure showed moderate positive significant correlations with body mass index. The differences in the pedobarometric and spatiotemporal gait parameters may result from the physiologic and mechanical demands that are put on the leading foot of handball players, which need more rehabilitation attention and protection to avoid expected injuries.

Why More Is Better: Integrating Sports Rehabilitation With Group-based Strength & Conditioning After ACL Reconstruction

Current return to sport (RTS) timelines after anterior cruciate ligament reconstruction (ACLR) suggest a minimum of 9 months before returning to competitive sports. Time, quadriceps limb symmetry index (qLSI) deficits and movement mechanics are recognized as indicators of RTS surgical limb performance and re-injury risk reduction. Current isolated therapy models may not provide appropriate skilled rehabilitation leaving individuals with impairments near the end of their care. PURPOSETo examine the effects of combined therapy and group-based strength training on known RTS strength criteria following ACLR surgery. METHODSTwenty-two individuals (17 +/- 2 years) having undergone ACLR (CON) were age, sex and graft harvest matched with individuals who participated in a group-based strength and conditioning program between 3 and 9 months post-surgery (ACLRSC). 900 flexion isometric dynamometer strength testing was administered at 3, 6 & 9 months post-surgery. Individuals maximally kicked out for five seconds and was repeated 3 times. Dependent strength variables were average peak torque (Nm), relative torque (Nm/kg) and qLSI (%). ACLRSC completed strength sessions between 3 and 9 month testing (40 +/- 1 visits). The primary quadriceps specific stimulus was closed kinetic chain, semi supported, single leg squat exercises beginning with an asymmetrical loading ratio of 3:1 of exercise sets and progressed to 2:1 and 3:2 for the surgical limb compared to nonsurgical. Independent samples t-tests were used to determine differences in strength variables per group. RESULTSNo significant differences between groups at all time points in surgical limb average peak torque or relative torque (p > .05) was. No difference was found in qLSI at 3 or 6 (p > .05) months. However, at 9 months post-surgery qLSI was significantly higher in the ACLRSC group compared to CON (p = 0.03). CONCLUSIONIndividuals who completed combined therapy and training during rehabilitation reach RTS qLSI criteria at 9 months post-surgery compared to those who do not complete additional training. This model of combined therapy and group-based strength training proves to increase positive functional outcomes after ACLR. It further justifies the importance of a team based, patient centered, objective measure driven rehabilitation model.

Фізкультурно-спортивна реабілітація у системі галузевих соціальних практик

The purpose of the study was to determine the essence and content of physical culture and sports rehabilitation as components of industry social practices. Materials and methods. Systemic approach, methods of analysis and synthesis, documentary method, methods of scientific induction and deduction were used in the study. Results and discussion. The peculiarities of the use of the term "rehabilitation" in the historical context, from the time of the First World War to the present day, are analyzed. Scientists are unanimous in the opinion that rehabilitation is a system of state, socio-economic, medical, professional, pedagogical, professional and other measures aimed at restoring health, the functional state of the human body and its working capacity. It has been studied that rehabilitation is a complex multifaceted concept, which means "restoration" and involves different types of rehabilitation. It has been established that physical culture and sports rehabilitation is a system of measures developed with the use of physical exercises to restore a person's health and is aimed at restoring and compensating with the help of physical culture and sports the functional capabilities of his/her body to improve his/her physical and psychological state. Taking into account the belonging of physical culture and sports rehabilitation to the field of physical culture and sports, which studies the impact of physical culture and sports on health, physical development and physical capabilities of the body, as well as on the recovery of athletes after injuries and illnesses, the application of physical culture and sports will contribute to the significant strengthening and improvement of the effectiveness of the recovery of athletes after injuries and illnesses. Conclusion. Physical culture and sports rehabilitation is an actual object of scientific research. As a postulate of scientific research in the field of physical culture and sports rehabilitation, we accept the statement that rehabilitation is a system of state, socio-economic, medical, professional, pedagogical, professional and other measures aimed at restoring health, the functional state of the human body and its working capacity. In contrast to physical therapy, which is based on the diagnosis and assessment of the functional state of the patient taking into account nosology, and involves the use of physical exercises along with medical and physiotherapeutic measures, physical culture and sports rehabilitation has a predominant focus on restoring and compensating the body's functional capabilities, physical and psychological state of a person with the help of physical education and sports. One of the main methodological provisions of physical culture and sports rehabilitation should be a comprehensive multidisciplinary approach, which involves the formation of the "FSR team" for the recovery of the athlete's condition from specialists in the field of physical culture and sports, and the involvement of specialists from other specialties in a consultative mode

Effect of running classes on the stress level of combatants

The full-scale war in Ukraine is having a significant psychological and physical impact on combatants. One of the negative consequences of war is combat stress, accompanied by the action of stress factors that negatively affect psychological and physical health, reducing the process of socialization to peaceful life. At the same time, there are not enough studies covering the solution of these issues with the help of adaptive physical culture (APC), which confirms the relevance of the chosen topic. Purpose: to determine the impact of running classes on combatants who have the consequences of combat stress. Material & Methods: the research was carried out on the basis of the National Council for Sports Rehabilitation of Defenders of Ukraine in Kyiv. It was attended by 40 combatants. The following methods were used in the course of the study: theoretical analysis and generalization of scientific and methodological literature, pedagogical testing, pedagogical experiment, methods of mathematical statistics. Results: at the end of the pedagogical experiment, the participants in the hostilities determined the level of stress according to the "Modified method for determining the level of stress by L. Ryder", before and after running classes. Based on the data after the study, it was found that at the initial stage, 77% of combatants had a high level of stress, and 13% had an average level of stress. At stage 2, after the use of APC (within 1 year), the level of stress among combatants was reduced to 50% – medium, 50% – low, which shows the effectiveness of the use of APC (running classes). Conclusions: a study was conducted with the determination of the level of stress according to the "Modified method of the level of stress according to L. Rieder" and the positive effect of running was shown. Measures are proposed to help reduce the level of stress among combatants. The dynamics of the results indicates the stability of reducing the level of combat stress with the help of running, which confirms the expediency of organizing the training process for combatants.

Influence of beta-rhythm neurofeedback on the functional state of the cardiovascular system of athletes

BACKGROUND: The study of the effects of urgent and long-term adaptation of the cardiovascular system of athletes under the influence of beta-rhythm neurofeedback expands its corrective and restorative potential for use in the practice of sports medicine and rehabilitation.
 AIMS: Study of the restorative and rehabilitation potential of the influence of beta-rhythm neurofeedback on the functional state of the cardiovascular system of athletes.
 MATERIAL AND METHODS: The course of neurofeedback on the beta rhythm of the brain consisted of 10 sessions, including a graphical and game version of the representation of the controlled parameter (beta rhythm) on the computer monitor screen, the success of controlling the beta rhythm with the specified conditions of voluntary muscle relaxation during the session was supported by visual and auditory biological feedback. Registration of indicators of the cardiovascular system was carried out before and after the 1st, 5th and 10th sessions of the course, the dynamics during the course and individual sessions is represented by the growth rate (%) of the indicators.
 RESULTS: A course of neurofeedback on the beta-rhythm of the brain of 10 sessions were young athletes (n=1020) aged 1821, representatives of cyclic, acyclic and game sports in the preparatory period of the training cycle.
 The effects of urgent adaptation in athletes at the 1st session of the neurofeedback course according to the beta-rhythm of the brain are reflected by positive changes in the strengthening of the vagal influence of the parasympathetic nervous system on the functional state of the cardiovascular system, expressed in a decrease in heart rate, systemic pressure, performance and pumping functions of the heart, in the transition of the type of regulation of blood circulation from the unfavorable hyperkinetic type to the physiological ― eukinetic ― type. At the same time, the load on the peripheral vascular bed increased, especially on its precapillary section.
 The effects of long-term adaptation at the 10th session of the neurofeedback course according to the beta-rhythm of the brain are represented by systemic rearrangements with an increased influence of the parasympathetic nervous system in the functioning of the cardiovascular system of athletes, reflected in the maximum decrease in heart rate throughout the course, in an equivalent decrease in systemic pressure, stabilization of performance and pumping function of the heart, achievement and preservation of the eukinetic type of regulation of blood circulation, achievement of a stable stable state of the central and peripheral vascular bed with a slight response to environmental factors.
 CONCLUSION: A course of neurofeedback on the beta-rhythm of the brain of 10 sessions helps to reduce stress in the functioning of the cardiovascular system of athletes by enhancing the vagal influences of the parasympathetic nervous system, has a positive effect on heart rate, systemic pressure, performance and pumping function of the heart; promotes the transition from an unfavorable hyperkinetic to a physiological eukinetic type of circulatory regulation; has a positive effect on adaptive changes in indicators of general and peripheral vascular resistance. The revealed effects of the course of neurofeedback on the beta-rhythm of the brain are of a pronounced corrective and restorative nature during the intense functioning of the cardiovascular system of athletes and can be used in sports rehabilitation and rehabilitation practice.

Relationship between Lower Extremity Fitness Levels and Injury Risk among Recreational Alpine Skiers: A Prospective Cohort Study.

Background: Although the importance of physical fitness for injury prevention is recognized in sports medicine and rehabilitation, few studies have investigated this factor among recreational alpine skiers. Objective: To determine the effect of lower extremity fitness on the risk and severity of injury among recreational alpine skiers. Method: This prospective cohort study involved 117 recreational skiers at two alpine resorts during the 2021–2022 winter season. Anthropometric characteristics, skiing skills, and lower extremity agility (hexagon test), balance (Y-Balance Test), and endurance (60-s squat test) were assessed before the winter season. All of the participants were divided into an injured group and an uninjured group, based on whether an injury was recorded throughout the season. Results: In binary logistic regression, the hexagon test duration and composite Y-Balance Test score were significant injury risk factors (p < 0.05). Ordinal polytomous logistic regression revealed no significant factors for injury severity (p > 0.05). Conclusions: Recreational alpine skiers with inferior lower extremity agility or balance may have a higher injury risk and this must be considered when assessing individual risk. In the context of injury prevention, regular neuromuscular training and testing, including agility and balance aspects should be recommended to skiers.
