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.
ABSTRACT Work-related musculoskeletal disorders are seen as a public health problem, and can often lead to temporary or permanent incapacity to work. Exercises can be indicated to prevent musculoskeletal disorders, allied to ergonomic intervention as a preventive approach. Objectives: The objective of this study is to analyze the effects of workplace muscle strengthening kinesiotherapy in the reduction of pain and discomfort in the upper limbs and cervical region perceived by the workers of a university hospital. Methods: After a priori sample size calculation based on pain numeric scale, 166 volunterrs will be recruted and assigned randomly to the "labor kinesiotherapy" group (GCL) or to the "control group" (CG), considering 10% sample size lost and intention to treat. The primary outcomes will be the pain perceived by the Numerical Pain Scale (NDT) and Nordic Questionnaire, and isokinetic muscle strength through the mean peak torque work of shoulder abduction. The discomfort and disability will be evaluated by the PSFS and QuickDASH questionnaires. The Ergonomic Analysis of Work will be evaluated by the manual "Ergonomic Analysis Focused on Activities" - EAFA and application of QEC, RULA, REBA and HARM tools. Statistical analysis will be performed through PASW Statistics ™, version 20.0. The independent sample T test will be used to compare the groups. The Cohen index will be set for the effect size calculation. All analyzes will be conducted with 95% confidence interval and p <0.05 significance.
This intervention, called MMP®, is a procedure whereby drugs are injected through tattoo machines.
The purpose of this study is to evaluate the safety and immunotherapeutic activity of cemiplimab in participants with hepatitis B virus (HBV) on suppressive antiviral therapy.
This is a randomized controlled trial to evaluate the use of LASER, Micro Ablative radiofrequency and topic strogen to treat symptoms of vulvovaginal atrophy of post menopause.
A double-blinded randomized controlled crossover trial will be conducted, and all participants will undertake non-immersive VR tasks and tDCS-active or tDCS-sham. Group 1 will start with ten sessions of tDSC-active combined to VR tasks. After one-month washout, this group will be reallocated to another 10 sessions with tDCS-sham combined to VR tasks. In contrast, Group 2 will do the opposite protocol (participants will start allocated to ten sessions of TDCS-sham and VR tasks, and after one-month washout period will be reallocated to ten sessions of tDCS-active and VR tasks). All protocol will have the assessment of Autonomic Nervous System, through Heart Rate Variability Analysis.
Introduction: Strength training (ST) is an important non-pharmacological means to reduce blood pressure (BP). Objective: To verify the pressure response of women after 8 weeks of ST. Method: Fourteen women were divided into young group (YG) and middle age (MAG) and submitted to ST for 8 weeks, lasting 60 minutes in 11 alternating exercises per segment with intensity of 12 to 13 on the subjective perception scale of effort. BP was verified at weeks 1, 4 and 8.
Objective: To investigate the effects of EMG biofeedback training on the pattern of scapular muscle activation and kinematics in subjects with subacromial pain syndrome. Methods: This is a randomized controlled trial, which will be composed of 40 volunteers of both genders, aged between 30 and 60 years. All volunteers will undergo pre-assessment (IA): pain sensation, pain and function, shoulder range of motion, muscle strength, electromyographic activity and kinematics of the shoulder complex. After the initial evaluation, the volunteers will be randomly divided into two groups for the intervention: exercises group (GE - conventional exercises with elastic band) and Biofeedback group (BG - Biofeedback training). The intervention protocol will last eight weeks. After four weeks, the second assessment (SA), similar to IA, will be performed and the global change perception questionnaire will be added. At the end of the intervention protocol, the third evaluation (TA), similar to SA, will be performed. A follow-up will be performed 4 weeks after the end of the intervention protocol, with the assessment being equal to TA. Statistical Analysis will be performed through Statistical Package for Social Sciences (SPSS) software version 20.0 for Windows, following the principles of intention-to-treat analysis. The descriptive analysis will use the mean as a measure of central tendency and the standard deviation as a measure of dispersion. A mixed model ANOVA will be performed for intra and intergroup comparisons.
It's evident that the literature shows good results on the use of aesthetic ultrasound in the treatment of localized fat, however, little has been explored so far, about possible psychological influences of this method and therefore, it is believed that it is pertinent to elaborate studies that include a placebo group, in order to measure the real effects from the exclusive application of ultrasound. Therefore, the objective of this study will be to verify the influence of the application of aesthetic ultrasound in the treatment of localized fat, using for both clinical, biochemical and functional parameters.
The purpose of this study is to assess the efficacy of a fixed dose combination (FDC) of glecaprevir/pibrentasvir (G/P) given for 4 weeks in acute hepatitis C (HCV)-infected participants, with or without HIV-1 coinfection.
Owing to the rarity, severity, speed of progression and fatal prognosis of infantile and juvenile GM1, there is a limited understanding of overall disease progression and meaningful outcome measures. This study aims to build a natural history data set through collection of a number of clinical, imaging, and laboratory assessments that may be specific predictors of GM1 disease progression and clinical outcome. Having a GM1 natural history data set can inform potential efficacy endpoints and biomarkers for future clinical trials. This natural history study will follow up to 40 subjects diagnosed with GM1 gangliosidosis (up to 20 infantile (Type 1) and 20 late infantile/juvenile (Type 2)) for up to 3 years. Visits will be conducted every 6 months, during which several procedures will be performed and the data recorded in order to learn about the natural course of the disease, including changes in clinical and neurological assessments and electrophysiologic, imaging and biofluid biomarkers. Study procedures include: physical & neurological exam, blood & urine sample collection, questionnaires & assessments of development, seizure diary, ECHO, ECG, x-ray and ultrasound (if MRI not performed), EEG and genetic testing (if not already done). The following procedures are subject to local/institutional policies and the medical discretion of the Study Physician: MRI, lumbar puncture (spinal tap) and General anesthesia/sedation (for MRI and LP).
