There are about 10004 clinical studies being (or have been) conducted in Brazil. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The clinical analysis of athletes has been performed in the sports field to obtain parameters for reliable evaluations. Among the tools used is the myotonometry, an analysis capable of quantitatively measuring tone, stiffness and elasticity. Its reliability has been tested in several populations, however, showing changes in results and presenting high variability in the confidence interval, also, the values of myotonometry differ according to sample specificity and the biomechanical properties of each muscle. Therefore, it seems pertinent to perform the reliability analysis in swimming athletes and verify their applicability and if the values of tone and muscular biomechanical properties vary according to the specificity of the modality. It will be a test and retest study composed of 50 young male and female swimming athletes, aged between 12 and 20 years. The evaluation of myotonometry will be performed randomly by two evaluators and the parameters measured will be: tone, stiffness, elasticity, relaxation time of mechanical stress and displacement. In the test stage, the first evaluator will perform the measurements bilaterally on the muscles and the second evaluator will perform the same measurements in the same order immediately after the first one. After 15 minutes, the retest will be performed following the same order of evaluators in the test. For characterization of sample will be used descriptive statistic through central tendency and variability for all variables collected. Relative reliability will be tested by the Intraclass Correlation Coefficient (ICC). Absolute reliability will be verified by means of standard error of measurement (SEM), values of least detectable change (MMD) and coefficient of variation (CV). The statistical package SPSS Statistics 22.0 will be used to conduct the reliability analyses.
To evaluate the intra- and inter-rater reliability of a test of active shoulder proprioception with a laser pointer in swimming athletes and to describe the profile of the proprioception measures characterizing the sample according to the specialty within the sport and the category of the athletes.
An intertrochanteric (ITF) trochanteric fracture of the femur is an exclusively extra capsular fracture in which the fracture line extends from the greater trochanter to the lesser trochanter. Its incidence has increased significantly over the past decades and is expected to double in the next 25 years, with an important global economic impact . It affects women in the seventh and eighth decades of life, an age group older than femoral neck fractures. For this reason, the mortality of intertrochanteric fractures is twice that of the femoral neck. The treatment is surgical, in which the objective is the stable internal fixation and the patient's early ambulation. Functional outcomes and treatment mortality are related including factors perioperative anemia and blood loss.Even so, even with these precautions, blood loss in this surgical procedure appears to be greater than expected, with blood loss of the order of 2100ml. Blood loss management and the inherent risks of anemia can be circumvented with blood transfusion. However, blood transfusion is not without risks and complications, such as hypersensitivity and hemolytic reactions, cardiac overload, infectious diseases. Homologous transfusions are associated with prolonged hospital stay, increased costs and increased patient morbidity and mortality. So, alternatives have been used to avoid the use of blood such as saline solutions, use of erythropoietin and antifibrinolytic agents . Tranexamic acid (TXA) is a drug that interferes with fibrinolysis, in use for more than 50 years in surgery, particularly in cardiac surgery. Only recently, TXA has sparked interest in orthopedic surgeries. Studies have shown the effectiveness and safety of TXA at FIT, but presented different forms of administration (intravenous, topical, infiltrative) . Despite promising results to contain bleeding in elective orthopedic surgery and fractures, in daily practice, TXA is not very popular, especially in fractures, and has not been used routinely by all doctors. Studies have not been found in the literature about the topical use of TXA compared to intravenous use in FIT.
COVID-19, an acute respiratory disease caused by coronavirus-2 (SARS-CoV-2), and in most cases, causes mild to moderate symptoms of fever, cough and dyspnea. However, a not insignificant portion, given the total number of people affected, will present symptoms of severe acute respiratory failure and multiple organ failure, requiring hospitalization under intensive care, use of mechanical ventilation, prolonged period of immobilization and, consequently, physical, cognitive and psychological damage, which may affect survivors for a long period after hospitalization. All of these factors are known to have an impact on various areas of life: personal, social and economic, which makes the need for continued specific care after hospital discharge relevant. In this context, the role of rehabilitation programs is fundamental, aiming not only at a safer dehospitalization, but also at the continuity of care with the objective of restoring the biopsychosocial skills of these individuals, allowing functional independence for activities of daily life and a shorter return physical and social activities performed before the disease. However, the big challenge for the health system is how to offer this on a large scale. Therefore, knowing the clinical and functional profile of these patients at discharge and verifying the viability of a digital platform for rehabilitation and monitoring of these patients is the first step to allow the creation of a new form of continuity of care and access to affected patients with serious diseases such as COVID-19 and other syndromes capable of generate functional impairment. Therefore,the investigators objective is to characterize and monitor the functional profile and exercise capacity of patients affected by COVID-19 at the hospital discharge, as well as to verify the viability and compliance of patients to the use of a digital platform for the application of a distance rehabilitation program.
Social distancing during the COVID-19 pandemic could lead to clinical and functional deterioration of people living with chronic respiratory diseases (CRD). As they are considered risk group for COVID-19, it is not recommended that they leave their house and have interaction with people outside. Thus, most of them have not been attend Pulmonary Rehabilitation sections since the beginning of pandemic, neither exercising outdoor, experiencing drastic restrictions in their activities of daily living. It is well known that low level of physical activity in daily life (PADL) in this population is related to poor prognosis, including higher chance of hospitalization due to exacerbation and mortality. Therefore, the aim of this study is to evaluate the short- and mid-term impact of the COVID-19 pandemic on the clinical, physical and functional conditions and the PADL level of people living with CRD (chronic obstructive pulmonary disease, asthma and interstitial lung diseases). Participants will be assessed during the social isolation period and they will be reassessed immediately after release from social isolation. Thus, the subjects will be followed-up during 12 months to record symptoms, functional status, quality of life, exacerbations and hospitalizations. The researchers' hypothesis is that those patients will present very low level of PADL in association to sedentarism, poor functional status, more symptoms of dyspnoea, anxiety and depression, poor sleep quality and, consequently, will present more episodes of acute exacerbation of the disease and more hospital admission during the study protocol.
The purpose of this study is to monitor short-term changes in tissue oxygen saturation and local blood flow as results of changing from supine to prone position in ARDS COVID-19 patients
Summary: Low back pain is the leading cause of deficiency and loss of productivity worldwide. No evidence of any particular exercise was more effective than another for treating nonspecific low back pain. Objective: To evaluate the efficacy of two resistance training protocols, with different techniques for performing lower limbs exercises, in improving vertebral posture and reducing symptoms of low back pain. Methods: Randomized parallel clinical trial with two arms: Restricted Group (GR) performed all squat and Stiff exercises with neutral vertebral posture and the Complete Group (CG) performed the same exercises prioritizing the complete range of motion. Both groups had a 12-week intervention with 36 resistance training sessions. This study was conducted between November 2020 and April 2021 in Goiás (Brazil). Thirty-two participants aged 18 to 69 years with nonspecific low back pain were recruited in the extension project of the Faculty of Physical Education and Dance of the Federal University of Goiás (UFG), at the Hospital das Clínicas - UFG and at the Campos Samambaia Health Center. To ensure blindness, participants did not know why the technique of movement between them was different. The movement technique was monitored by one teacher per participant throughout the training and cannot be altered by participants at risk of compromising the results. Spinal posture was evaluated by three-dimensional reconstruction and posture quantification using dynamic posture software and pain symptoms were evaluated by the Brief Pain Inventory and Rolland Morris Questionnaire. Statistical analysis was performed in the Software SPSS and MATLAB. The Shapiro-Wilk and Bartlett tests were used to confirm the normal distribution and similar variances in the distribution of the data. The other quantitative and qualitative variables were analyzed by nonparametric statistical methods. Quantitative data with normal distribution were reported by means of means and standard deviation, minimum and maximum values, and the other data by median, interquartile range, minimum and maximum values. The pre-intervention conditions of the groups were compared by independent t-test. Two-way ANOVAs (groups X time) were used for group intervention effect comparisons for quantitative data variables with normal distribution. Significance level of 5%. The size of the effect of the results will be calculated using cohen's test.
This study is a randomized, single-blinded, parallel, superiority, controlled trial. The main objective is to verify the effects of a telehealth stretching exercise program on pain, depression, sleep parameters and functionality of women with fibromyalgia, during the Covid-19 pandemic. Participants will be women with primary fibromyalgia, seen at public and private health services, in the city of Pelotas (south of Brazil). Participants will be recruited through social networks, newspapers and support from the National Association of Fibromyalgia and Correlated Diseases (Anfibro). Eligible participants will be randomized, stratified by age (30 to 45; 46 to 60), and allocated to one of the two groups, experimental or control. The experimental group will receive a telehealth stretching exercise program twice a week (guided by a professional) and counseling guide to stretching exercises with explanatory video regarding the execution of the protocol proposed by the guide. The total duration of exercise program will be 40 minutes (will be 12 exercise, 3 sets of each stretching for 10 seconds, carried out individually by a video call application - WhatsApp). The control group will receive only counseling guide to stretching exercises with explanatory video regarding the execution of the protocol. Both interventions will last 12 weeks, with outcomes evaluations in three moments: baseline (week 0), midpoint (week 6) and after the intervention (week 13). The following outcomes will be evaluated: generalized index of pain, fatigue and severity of symptoms, depression, level of physical activity, functionality, quality of life and sleep. All outcomes will be evaluated by questionnaires self-completed, that will be answered on Google Docs by video call, with exception of functional test that will be applied by video call. The study's hypothesis consists of improving outcomes for both groups, but with superiority for the experimental group.
