Assessment of the Effectiveness of Rehabilitation after Total Knee Replacement Surgery Using Sample Entropy and Classical Measures of Body Balance.

Exercises in virtual reality (VR) have recently become a popular form of rehabilitation and are reported to be more effective than a standard rehabilitation protocol alone. The aim of this study was to assess the efficacy of adjunct VR training in improving postural control in patients after total knee replacement surgery (TKR). Forty-two patients within 7-14 days of TKR were enrolled and divided into a VR group and a control group (C). The C group underwent standard postoperative rehabilitation. The VR group additionally attended twelve 30-min exercise sessions using the Virtual Balance Clinic prototype system. Balance was assessed on the AMTI plate in bipedal standing with and without visual feedback before and after the four-week rehabilitation. Linear measures and sample entropy of CoP data were analyzed. After four weeks of rehabilitation, a significant reduction in parameters in the sagittal plane and ellipse area was noted while the eyes remained open. Regression analysis showed that sample entropy depended on sex, body weight, visual feedback and age. Based on the sample entropy results, it was concluded that the complexity of the body reaction had not improved. The standing-with-eyes-closed test activates automatic balance mechanisms and offers better possibilities as a diagnostic tool.

[Burnout syndrome among physiotherapists].

BACKGROUND: Burnout is a syndrome of emotional exhaustion, depersonalization, and a reduced sense of personal accomplishment. Symptoms of burnout include mental and physical exhaustion, accompanied by psychosomatic disorders and emotional problems. Burnout occurs most often in people employed in occupations requiring working with people (human services) as a result of coping with stress and experience numerous failures at work. The aim of the research is the analysis of burnout among physiotherapists and demographic factors and conditions that may contribute to the burnout. MATERIAL AND METHODS: 212 (137 woman and 75 man) physiotherapists completed an anonymous questionnaire to assess burnout created by Owczarek and Olczyk. The age of respondents ranged between 20 to 56 years, with work experience from several months to more than 30 years. RESULTS: Total score of burnout was 115,66 (SD 21,78). On the scale of attitude to work 36,82 was achieved, workload - 34,76, contact with the patient - 27,54, and an attitude towards stress - 16,54, which means that the result obtained fit in the lower zone including average results concerning the level of burnout. Women had a higher level of professional burnout than men. Respondents who reported that their working conditions are not conducive to achieving therapeutic success (quality of equipment, size of treatment rooms, treatment technologies), exhibited a higher level of burnout. The average result of the level of burnout among physiotherapists is lower than all the results obtained in other occupational groups of health care workers, lead with the same diagnostic tool. CONCLUSIONS: Burnout syndrome among practicing physiotherapists require further study, taking into account the type and quality of jobs, but also the level of referral among professional physiotherapists.

Effect of hamstring tissue flossing during warm-up on sit and reach performance.

BACKGROUND: Tissue flossing, also called voodoo flossing, is becoming a popular adjunct to athletic training to improve joint range of motion and muscle strength. The authors of this technique believe that tissue flossing can be used during warm-up. This study investigated the effect of tissue flossing during warm-up on the range of motion in the sit and reach test. METHODS: The study enrolled 40 recreational athletes divided into an experimental and control group consisting of 20 participants each. The range of trunk flexion was assessed with the sit and reach test. Participants were tested before as well as immediately and 15, 30 and 45 minutes after completing the 9-minute warm-up. During the warm-up, athletes in the experimental group wore a floss band on the thigh muscles, while athletes in the control group exercised without wearing a floss band. RESULTS: The sit and reach test revealed an improved range of motion after the warm-up in both groups (P<0.05). The improvement was noted at all time points. Regression analysis showed no effect of any of the study parameters (group assignment, sex, age, body mass index, pain intensity on a visual analogue scale) on the improvement in the sit and reach test results. CONCLUSIONS: The similar results obtained in both groups indicate that there may not be a rationale for using tissue flossing during warm-up to improve trunk and hip flexibility.

Effectiveness of Warm-Up Exercises with Tissue Flossing in Increasing Muscle Strength.

Tissue flossing is an increasingly popular method in physiotherapy and sports. There is a belief that tissue flossing can improve range of motion and muscle strength, shorten muscle recovery time, and reduce the risk of injury. The aim of this study was to analyse the effectiveness of tissue flossing for immediately improving muscle strength in recreational athletes when it is performed during warm-up. All participants were randomly assigned to either an experimental group (n = 36) or a control group (n = 34) using a random number generator. The experimental group (n = 36) performed an intervention comprising exercises with muscle tissue flossing and exercises without flossing. The control group (n = 30) performed the same protocol without a floss band. Muscle strength was measured for knee flexion end extension at three speeds (60, 120, and 180 °/s) 3 times. Analysed parameters include peak torque, work, and power related to body weight, flexors−extensors ratio, and time to peak torque. There were no significant changes in the muscle strength parameters from before to after the warm-up in either group (p > 0.05). Significantly lower values of peak torque, work, and power were observed in the experimental group during the warm-up with the floss band applied to muscles (p < 0.05). No clinically significant changes in time to peak torque or flexors−extensors ratio were observed. A single application of flossing does not improve muscle strength or power and can even reduce individuals' maximum muscle strength capabilities.

Effectiveness of Early Rehabilitation with Exergaming in Virtual Reality on Gait in Patients after Total Knee Replacement.

Total knee replacement (TKR) is the treatment of choice for advanced stages of osteoarthritis but it requires good postoperative rehabilitation. This study aimed to assess the effectiveness of exercises using virtual reality to improve gait parameters in patients after TKR. Fifty-nine patients 7−14 days after TKR surgery were divided into a study group (VRG, n = 38) and a control group (CG, n = 21). Both groups underwent the same 4-week rehabilitation protocol. The VRG group had 12 additional nonimmersive virtual reality game sessions on the Virtual Balance Clinic prototype system at 30 min each, focusing on gait and balance improvement. Spatiotemporal, force and foot plantar pressure parameters were collected on an instrumented treadmill during a 30 s walk. The most significant improvement was in the symmetry indices of forefoot force, maximum forefoot force, loading response time, and preswing time (p < 0.05) in both groups. Gait speed increased by 31.25% and 44% in the VRG and CG groups, respectively (p < 0.005). However, the extra exergaming sessions did not significantly improve rehabilitation outcomes. Therefore, additional VR training does not improve gait better than standard rehabilitation alone, but the improvement of gait, especially its symmetry, is significant within the first six weeks after surgery.

Nonlinear and Linear Measures in the Differentiation of Postural Control in Patients after Total Hip or Knee Replacement and Healthy Controls.

Primary osteoarthritis treatments such as a total hip (THR) or knee (TKR) replacement lead to postural control changes reinforced by age. Balance tests such as standing with eyes open (EO) or closed (EC) give a possibility to calculate both linear and nonlinear indicators. This study aimed to find the group of linear and/or nonlinear measures that can differentiate healthy people and patients with TKR or THR from each other. This study enrolled 49 THR patients, 53 TKR patients, and 16 healthy controls. The center of pressure (CoP) path length, sample entropy (SampEn), fractal dimension (FD), and the largest Lyapunov exponent (LyE) were calculated separately for AP and ML directions from standing with EO/EC. Cluster analysis did not result in correct allocation to the groups according to all variables. The discriminant model included LyE (ML-EO, ML-EC, AP-EC), FD (AP-EO, ML-EC, AP-EC), CoP-path AP-EC, and SampEn AP-EC. Regression analysis showed that all nonlinear variables depend on the group. The CoP path length is different only in THR patients. It was concluded that standing with EC is a better way to assess the amount of regularity of CoP movement and attention paid to maintain balance. Nonlinear measures better differentiate TKR and THR patients from healthy controls.

Activity of ozonated water and ozone against Staphylococcus aureus and Pseudomonas aeruginosa biofilms.

BACKGROUND: The known bactericidal properties of ozone have not been checked in relation to its action on bacterial biofilms. This is especially true of ozonated fluids. The aim of this study was to investigate the bactericidal activity of ozonated water and that of a mixture of ozone and oxygen against biofilms. MATERIAL/METHODS: Eighteen clinical strains of Staphylococcus aureus and Pseudomonas aeruginosa exhibiting various levels of antibiotic sensitivity were investigated. Bacteria were cultured in biofilm form on polystyrene titration plates for periods of 2 to 72 hours. The biofilms formed in this way were exposed to in statu nascendi ozonated water produced in a prototype device that had been tested in clinical conditions, or to a mixture of oxygen and ozone generated in the same device. Live cells in the biofilm were stained with a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) bromide solution. The degree of reduction of viable bacteria following ozone exposure was determined. RESULTS: Ozonated water was found to be an effective bactericidal agent against biofilms after as little as 30 seconds of exposure, while the bactericidal activity of the ozone-oxygen solution was much lower. Prolongation of the duration of biofilm exposure to the gaseous disinfectant to 40 minutes led to a reduction in the viable cell count, which nevertheless remained high. CONCLUSIONS: Unlike the ozone-oxygen mixture, ozonated water effectively destroys bacterial biofilms in vitro.

Can the sleep quality of patients with chronic neck pain be improved by muscle energy techniques combined with Swedish massage?

BACKGROUND AND PURPOSE: Muscle energy techniques (METs) are used to reduce tension in neck muscles and therefore, can be used together with Swedish massage to enhance its effect. The aim of this study was to assess if using METs combined with massage could improve sleep quality. MATERIALS AND METHODS: In this prospective, randomised controlled trial forty patients with chronic cervical spine pain were divided into two equal groups. Both groups attended 10 sessions of Swedish massage, and the study group additionally attended MET-sessions. Sleep disturbances were assessed with the Pittsburgh Sleep Quality Index (PSQI). RESULTS: A significant improvement in terms of sleep disturbances was seen in both groups. The MET group demonstrated improvement in all PSQI components. In the control group, the improvement included only 4 components of the index. CONCLUSION: Massage therapy combined with relaxing METs may be more effective than massage therapy alone in this group of patients.

Ozone disinfection of community pharmacies during the COVID-19 pandemic as a possible preventive measure for infection spread.

The COVID-19 pandemic is currently one of the major global health and economic challenges. An efficient method for reducing the transmission of the virus is a still unmet medical need. Existing experimental data have shown that coronavirus survival is negatively impacted by ozone, high temperature, and low humidity. Therefore, it is feasible to use area ozonation in pharmacies - the front line of the healthcare system. Nevertheless, further work is needed to evaluate the effectiveness of ozone disinfection to reduce the transmission of this virus in pharmacies, hospitals, and other public environments.

Antimicrobial activity of ozonated water.

BACKGROUND: The purpose of this study was to analyze basic bactericidal and fungicidal activity of ozonated water according to EN 1040 "Chemical disinfectants and antiseptics--Quantitative suspension test for the evaluation of basic bactericidal activity of chemical disinfectants and antiseptics" and EN 1275 "Chemical disinfectants and antiseptics--Quantitative suspension test for the evaluation of basic fungicidal or basic yeasticidal activity of chemical disinfectants and antiseptics" with additional clinical multidrug-resistant bacterial strains and evaluate whether the ozonated water acts as a rapid and efficient antimicrobial agent and as such could be applied during intraoperative ozone treatment for tissue protection against infection with pathogenic bacteria. MATERIAL/METHODS: A prototype device for intraoperative ozone therapy was used. Besides standard bacterial and fungal strains, 60 clinical bacterial isolates were analyzed. RESULTS: The ozone concentration in ozonated water was sufficient to kill almost all cells of the bacterial and yeast strains tested after 30 seconds. Effective action against Aspergillus brasiliensis spores required a longer time than those required in the case of bacterial cells or vegetative cells of yeast. CONCLUSIONS: The prototype device used in our study produced high ozone concentrations in freshly prepared ozonated water. This liquid complied with the requirements of the EN Standards: basic bactericidal and basic yeasticidal activities.

Effectiveness of spa treatment of osteoarthritis. Review of literature.

This paper is a review of the available current literature aiming to present the current knowledge of the efficacy of spa treatment. Individual papers are analysed in terms of their scientific reliability and compliance with the principles of evidence-based medicine. The analysis has been performed on the basis of Sackett's criteria for levels of evidence.

A comparative analysis of the clinical utility of the Staffelstein-score and the hospital for special surgery knee score (HSS) in monitoring physiotherapy of total knee replacement patients--preliminary study.

INTRODUCTION: Treatment efficacy assessment lies at the basis of Evidence Based Medicine (EMB). Specialised scores have recently been developed to present the patient's functional status to the doctor or physiotherapist in a rapid and accessible manner and to allow treatment efficacy monitoring. The present study aimed to assess the sensitivity and utility of the Staffelstein Score and HSS Knee Score in monitoring the progress of rehabilitation following total knee replacement surgery. MATERIAL AND METHODS: The study involved 24 patients who underwent knee replacement surgery due to degenerative disease of the knee joint. The HSS Knee Score and the Staffelstein Score (ST-score) were compared. Patients were assessed twice: prior to and after the completion of post-hospital rehabilitation. RESULTS: The mean results on admission and at discharge were: 50.1 (HSS) and 70.8 (ST), and 74.4 (HSS) and 99.5 (ST), respectively. There was a marked improvement according to both scales (p<0.005) both as regards overall scores as well as individual parameters. CONCLUSIONS: 1. The HSS and ST scores exhibit high sensitivity in assessing pain, difficulty performing activities of daily living and in assessing the results of physical examination of the knee joint in patients who following knee replacement surgery. 2. The sensitivity of the HSS Knee Score may be adversely affected by assessment of instability and varus or valgus deformity of the joint due to a low variability of those parameters over time. 3. The assessment of the ability to perform activities of daily living using the two scores makes it possible to tailor exercises and adjust the rehabilitation programme to solve patients' specific problems.

Clinical efficacy of kinesiology taping in reducing edema of the lower limbs in patients treated with the ilizarov method--preliminary report.

INTRODUCTION: Postoperative edema of predominantly lymphatic origin is a significant hindrance to physiotherapy in patients subjected to limb lengthening by the Ilizarov method. New treatment methods are being sought, and Kinesiology Taping is one of them. MATERIAL AND METHODS: The study involved 24 patients of both sexes subjected to lower limb lengthening using the Ilizarov method who had developed edema of the thigh or crus of the lengthened extremity. The mean age of the patients was 21 years. The patients were randomized into two groups of twelve, which were then subjected to 10 days of standard physiotherapy. The study group was additionally treated with Kinesiology Taping (lymphatic application), while the control group received standard lymphatic drainage. Treatment results were assessed by comparing the linear circumferences of the lower limbs before and after the treatment. RESULTS: The application of Kinesiology Taping in the study group produced a decrease in the circumference of the thigh and crus statistically more significant than that following lymphatic drainage. CONCLUSIONS: 1. Both standard edema-reducing treatment in the form of lymphatic massage and Kinesiology Taping significantly reduced lower limb edema in patients treated by the Ilizarov method. 2. The application of Kinesiology Taping in the study group produced a significantly faster reduction of the edema compared to standard lymphatic massage.

Strategies for neuroprotection following spinal cord injury.

Progress in neuropathology has made possible the description of local responses of neural tissue in early stages after traumatic spinal cord injury (SCI). The recent identification of multiple factors responsible for secondary spinal cord damage and for potential regenerative abilities has not resulted in the development of a standard for neuroprotective therapy in SCI patients. The paper reviews current knowledge concerning the sequence of biochemical events in the injured spinal cord and gives an overview of therapeutic possibilities for preventing the spread of secondary injury. The literature survey has led to the following conclusions: 1. The primary zone of traumatic damage enlarges due to local vascular disturbances, hypoxia, and the resulting inflammation. 2. Inflammation in the region of secondary injury, apart from having a destructive impact, is the source of substances which may induce neural tissue repair. 3. The administration of methylprednisolone and surgical decompression of the spinal cord within several hours after SCI improves functional and neurological outcomes in patients with incomplete neurological deficits. Currently there is no sufficient scientific evidence to support the safety and efficacy of other neuroprotective methods in humans.

Electromyographic and clinical evaluation of the efficacy of neuromobilization in patients with low back pain.

BACKGROUND: Evidence for the efficacy of therapeutic methods and procedures is being sought in accordance with the principles of Evidence Based Medicine. The choice of a physiotherapy method should be based on its documented efficacy. The purpose of the investigation was to analyse changes in functional disorders of resting muscle tone following neuromobilization treatment in patients with chronic low back pain. MATERIAL AND METHODS: The study involved 108 outpatients treated due to low back pain and neurogenic functional pain referred to the lower extremity. The treated group was subjected to two weeks of neuromobilization-based physiotherapy. The control group received standard physiotherapy, also over two weeks. RESULTS: The treated group demonstrated a statistically significant decrease in muscle tone in all muscles examined, clinical improvements (Laseque test and Bragard test results), decreased pain threshold estimated with a Visual Analogue Scale (VAS). In the control group, the only statistically significant change was a decrease in gastrocnemius muscle tone. CONCLUSIONS: 1. The results of the examinations appear to suggest that evaluation of resting muscle tone can be used to provide an objective assessment of the analgesic efficacy of physiotherapy, including neuromobilization. 2. In the treated group, neuromobilization therapy was superior to standard physiotherapy as regards eliminating or decreasing elevated resting muscle tone in response to pain in patients with low back pain. 3. Neuromobilization produced a significant improvement in clinical test results and clinical symptoms in the treated group as opposed to the control group, which demonstrates the efficacy of this therapy. 4. The results of the examinations show that tibialis anterior sEMG had the biggest diagnostic value for detecting changes in pain severity.

Repair therapies in spinal cord injuries.

Spinal cord repair therapies (SCRT) are experimental treatments which are attracting a growing interest among both spinal cord injury sufferers and their families as well as physicians and physiotherapists. Basing on current professional literature, this article presents the most important SCRT strategies. The majority of currently developed SCRTs are at the stage of experimental in vitro or animal studies. Few of these studies are in the early clinical trial stage or are being offered as non-standard commercial health care services. Basing on a review of the literature, it can be stated that currently there are few studies which meet the criterion of reliability, and their results make possible an objective assessment of the safety and efficacy of SCRT. Available study results are insufficient to confirm the advisability of widespread application of these methods.

The role of rehabilitation and methodological problems in spinal cord repair therapies.

Despite the rapid development of studies of spinal cord repair therapies (SCRT), there is still a dearth of reliable reports on their clinical usefulness. Basing on a review of current literature, this article emphasises the role and special character of comprehensive rehabilitation based on the modulation of central nervous system plasticity in the treatment of spinal cord injuries with the use of SCRT. Basing on guidelines by the International Campaign for Cures of Spinal Cord Injury Paralysis (ICCP), this article also discusses ethical and methodological issues of SCRT studies. Comprehensive motor rehabilitation exerts an effect that potentially modifies spinal cord plasticity and may significantly supplement SCRT, leading to expected functional effects. Encouraging results of animal studies cannot be directly translated into expectations regarding SCRT utility people. Ensuring a high quality of studies on SCRT efficacy and safety necessitates compliance with rigorous methodological requirements. Functional ability of the patient needs to be a significant end-point of SCRT studies.

Assessment of the Health-Related Behaviors of Men Practicing Combat Sports and Martial Arts.

BACKGROUND: Physical activeness is one of the main elements of lifestyle in terms of preventing civilization diseases. The main purpose of this study was to assess the selected health behaviors of men practicing combat sports and martial arts and to find out what features or variables may have an influence one's lifestyle. METHODS: Overall, 561 men aged 17-35 yr were enrolled and divided into three groups. Studies were conducted from March 2011 to June 2015 in Warsaw, Poland. The main research tool was Juczynski's Health Behaviour Inventory. The questionnaire includes 24 statements - descriptions of various health-related attitudes and behaviours - divided into four categories: proper eating habits, preventive behaviours, positive psychical attitude, and health practices. RESULTS: The persons practicing combat sports and martial arts presented the highest level of health behaviours. The result of Group 1 was significantly higher than the result of Group 2 (P=0.05) and Group 3 (P<0.001). The sportsmen from Group 1 obtained the highest result in the category of psychical attitude (3.5), which was similar to the result of the non-active group (3.29). The men belonging to Group 2 rated highest their eating habits (3.37). All groups obtained the lowest results in the category of preventive behaviours. CONCLUSION: The men practicing combat sports and martial arts showed high general level of health behaviours. It may give evidence to the intellectualization of sport and health training process, as well as to the fact of adopting the desired behaviours in everyday life.

Standards of Virtual Reality Application in Balance Training Programs in Clinical Practice: A Systematic Review.

OBJECTIVE: To determine the effect of virtual reality (VR) games on improving balance in different groups of neurological patients with a particular focus on the study quality and to determine the gold standard in VR training in these groups. MATERIALS AND METHODS: A systematic review of controlled trials published between January 2009 and December 2017 was conducted. The PubMed, SCOPUS, SPORTDiscus, and Medline databases were searched. Studies involved patients with stroke or Parkinson's disease or children with cerebral palsy. The Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of the included studies. RESULTS: A total of 20 studies met the inclusion criteria. The PEDro scores ranged from 4 to 8 points. Analysis of the rehabilitation programs revealed a very large discrepancy in the planned volume of exercises in different subgroups of patients. CONCLUSIONS: Overall, the comparison of VR interventions between conventional rehabilitation and no intervention exhibited significantly better results. However, these results should be interpreted with great caution due to the large diversity of the systems, games, and training volume used in the VR therapy. In all included studies, only several articles included objective methods to assess the effect of VR. In addition, most of the articles showed a high risk of bias, such as a lack of randomization and blinding or a small sample size. That is why further well-designed randomized control trials are required to evaluate the influence of VR on balance in different groups of neurological patients.

An attempt to assess the influence of primary disease on the results of therapeutic rehabilitation in an early post-operative period in orthotopic liver transplant recipients.

BACKGROUND: A retrospective analysis of the effects of early postoperative rehabilitation in patients undergoing orthotropic liver transplantation in correlation to the primary liver disease leading to transplantation. MATERIALS AND METHODS: In between 2000 and 2003 in the Department of General, Transplant and Liver Surgery of the Medical University of Warsaw Central Teaching Hospital, 213 orthotropic liver transplants (OLT) were performed. Full rehabilitation records were available for 136 patients. For statistical analysis, patients were divided into 5 different groups representing different causes of primary liver insufficiency. RESULTS: Achieved early rehabilitation results show that there was a strong correlation between the time at which physiotherapy was introduced and the ability to achieve a fully upright position in correlation to the primary cause of liver disease necessitating transplantation. The shown relationship is probably a direct effect of the time of disease progression before transplantation is required. The worst results were observed in group no. 4 where patients with acute and subacute liver insufficiencies were included, even though these patients had the lowest mean age. CONCLUSIONS: 1. The achieved results confirm the general compensation rule which states that the process of healing strongly depends on the time of disease development. 2. An analysis of the time, when rehabilitation was initiated and the ability of the patient to achieve a fully upright position in relation to the cause of liver insufficiency suggests that the reason for most delays is the inability to develop adequate compensational mechanisms as a result of rapid disease progression in cases of acute liver insufficiency.
