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.
Background: Osteoarthritis (OA) is highly prevalent in the elderly, with the knee being the most commonly affected joint in this population. Knee braces are often used to prevent common problems in knees during daily activities. The purpose of these devices is to decrease pain and improve functionality. In the literature some studies have tested the effectiveness of unloader brace for valgus or varus. However, the braces most used in the investigators' clinical setting and the less costly ones have not been described in quality studies in the literature. There are only few studies on this subject and they are methodologically inadequate. There are no studies that compared the effectiveness between the knee brace with metal hinges (no alignment) and knee brace without metal hinges. Objective: To evaluate the effectiveness of knee braces on pain, function and quality of life in the elderly with knee OA. Methods: Elderly with knee OA, both genders, with pain scale 3-7cm on a 10cm pain numeric scale were included. Of the 222 patients screened, 120 met the eligibility criteria and were randomized to the groups: without metal hinges, with metal hinges or control group. The groups without and with metal hinges received knee brace and were instructed to use it in daily activities, every day, during three months. Assessment for pain (NPS), function (WOMAC and Knee Lequesne) and quality of life (SF-36) were done at baseline and after 45, 90 and 180 days by a blinded assessor.
Background: Volleyball players constantly perform vertical jumps, the higher the height of the jump is better sports performance of these players. Several methods have been tested to improve jumping performance in these players. It will be investigated the addition of electrical stimulation and phototherapy to jump training in volleyball athletes. DESIGN: randomized controlled trial. METHODS: This study will be conducted with 36 male athletes volleyball with minimum experience of 12 months sport. Will be randomized and assigned to 3 groups (control group, NEMES group and group phototherapy). All 36 healthy volleyball athletes who passed the initial selection and agreed to participate in the study, conduct a muscle strength and jump training program, which is held in both legs simultaneously. The 12 healthy athletes electrical stimulation group will perform the same training program described above, but strength training is associated with electrical stimulation. The 12 healthy athletes participating in the phototherapy group will undergo a phototherapy protocol before performing the strength and jump training. All selected participants will undergo an assessment of muscle strength of knee extensors and evaluate the jump. These evaluations were baseline, 6 weeks and 8 weeks after baseline.
This is a Phase 3b, open-label, multicenter study to evaluate the proportion of subjects achieving sustained virologic response 12 weeks post-treatment (SVR12), in adults with genotype 1 (GT1) chronic HCV infection, who received treatment with ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin.
There are some treatments after Stroke. Among these, use forced therapy (FUT), which is based on overcoming learned disuse by reintroduction of the paretic upper limb in the performance of daily activities. There are different protocols FUT to the daily time constraint, the number of days and even the type of constriction. Researchers have developed a protocol using four weeks constriction, daily constriction 24 hours and with the free end of the weekends. Because it is a restrictive therapy, which requires the use of one of the arms and on the other hand, this mode of treatment is open to criticism, however, despite the efficacy of the protocol, patients do not have good adhesion to the protocol for the constriction severe over time. The objective of this work is to verify the safety of the developed protocol and analyze the feasibility of reducing the daily time of constriction 12 hours, with a new protocol movement constriction, easier to perform and more patient acceptance. Participate in this study 82 individuals hemiparetic post Stroke, which will be recruited to Neurovascular Diseases Clinic and will be registered at the Rehabilitation Center of Integrated State Hospital. Participants will be randomly divided into three groups: the FUT24 (non-paretic upper limb constriction 24 hours a day, five days a week for 4 weeks), the FUT 12 (non-paretic upper limb constriction for 12 hours a day, five days a week for 4 weeks) and CK (Classic Kinesiotherapy, at least 2 times a week for 4 weeks). Will be held weekly and after the end of the monthly monitoring reviews protocols. For the rating scales are use: National Institute of Health Stroke Scale, the Ashworth Scale, the Wolf Motor Function Test, the Motor Activity Log, Fugl-Meyer Assesment, dynamometry handgrip and surface electromyography (flexor and extensor muscles wrist). The researchers hope that this protocol does not bring damage to the upper limb in constriction and it is established a new protocol FUT easier to perform and more acceptable to patients, allowing the use of this technique by health professionals.
Purpose: To examine whether nasal breathing influences the perception of sound causing trade between hard and soft consonants in the writing of children in school age and the incidence of trade.
To determine whether treatment with alpelisib plus fulvestrant prolongs progression-free survival compared to fulvestrant and placebo in men and postmenopausal women with hormone receptor positive (HR+), HER2-negative advanced breast cancer, who received prior treatment with an Aromatase Inhibitor either as (neo)adjuvant or for advanced disease.
Background: Taking into consideration the ongoing inversion of the population pyramid and the limitations and medical conditions, which predispose to episodes of falling among elderly people, the implementation of exercises and physical treatments capable of promoting postural balance in the group studied is made necessary. Objectives: Assess the influence of the electronic platform Kinect Sensor® (KS) as a tool in the treatment of postural balance in elderly individuals. Method: The study included 10 elderly (60 to 70 years old) and 10 young (20 to 30 years old) individuals. Treatment protocol composed of five weeks with sessions performed twice a week with application of KS. Initial and final evaluation included static and dynamic balance instruments: Berg Balance scale and Timed up and Go and Romberg Tandem tests.
Predictive equations are the main clinical tool for determining resting energy expenditure (REE). Thus, it is important to investigate the accuracy and agreement of these equations in different populations and context of diseases. The purpose of this study is to investigate the accuracy and agreement of predictive equations of REE in overweight women with polycystic ovary syndrome (PCOS). The REE of all participants was measured (mREE) by means of indirect calorimetry and predicted (pREE) through ten equations basing on the anthropometric parameters (Harris & Benedict, WHO/FAO/UNU including weight, WHO/FAO/UNU including weight and height, Owen, Mifflin-St. Jeor, Institute of Medicine, Ireton-Jones, Müeller, De Luis and Lazzer).
The purpose of this study is to evaluate the safety and efficacy of ramucirumab in participants with hepatocellular carcinoma (HCC) and elevated baseline alpha-fetoprotein. Participants will be randomized to ramucirumab or placebo in a 2:1 ratio (Main Global Cohort and China Maximized Extended Enrollment [MEE] Cohort). Participants may also receive ramucirumab if eligible to be enrolled in Open-Label Expansion (OLE) Cohort.
The purpose of this study is to evaluate the therapeutic effects of the LED (627 +/- 10 nm) with respect to the localized pain and local swelling of ankle sprains in the initial phase.
