Filter by:The objective of this study is to investigate whether electromyography of the diaphragm during sleep in asthmatic children can be used to objectively monitor asthma control.
This is an observational analytical study of prevalent cases and controls.
The aim of this study was to verify if sodium bicarbonate (NaHCO3) suplementation promotes changes in the performance, muscular activity and strength of individuals trained during the intermittent and intense task . Twelve trained adult men will participate in this randomized, double-blind, crossover clinical trial. Each participant should receive two types of intervention with a 14-day interval between conditions: alkalosis (ALK) in which gelatinous capsules containing 0.3 g.kg -1 of NaHCO 3 and placebo (PLA) are administered, in which 0.3 g.kg-1 of Calcium Carbonate (CaCO3). The following results will be considered: electromyographic activity (EMG) of the quadriceps muscle, peak torque, pH, lactate, and perception of effort, recovery and pain questionnaires, which will be collected during intermittent and high intensity DI protocol. ANOVA of repeated measures will be used to verify possible differences between groups.
Introduction: It is suggested that increased cortical activity, induced by cerebral stimulation associated or not with other rehabilitation techniques, may potentiate the motor and functional therapeutic effects in individuals with neurological deficits. Objectives: To evaluate the electrical activity of the anterior tibial muscle (TA) and postural control of individuals with hemiparesis due to stroke following treatment with transcranial direct current (tDCS) stimulation and functional electrical stimulation (FES), associated or isolated). (EMG) and postural control by the Balance Evaluation Systems Test (BESTest). Both of which were collected at four different time points: pre-treatment, immediately after 10 treatment sessions, and 30 days follow-up after the interventions. Patients will be randomized into 4 experimental groups: tDCS anodic active + active FES+ active contraction TA, tDCS sham + active FES+ active contraction TA, tDCS anodic active+ placebo FES+ active contraction TA, tDCS sham+ FES sham+ active contraction TA. tDCS (2mA) will be applied over the motor (Cz) and cathodic vertex over the supraorbital region of the normal hemisphere and FES over hemiparetic TA by a researcher who will not be the one who will evaluate the anesthesia patient. The treatment will last 10 sessions, twice a week, with a time of 20 minutes.
The orthotics are auxiliary therapeutic resources indicated for the relief of pain, improves functional standard or correction of deformities. There is a lack of studies that analyze the biomechanical changes promoted by the Orthotics in functional pattern of the upper limb. The objective of this proposal is to analyse biomechanical changes in the functional upper limb pattern with the use of orthoses for patients with dysfunctions arising from musculoskeletal system trauma or burns, aiming to contribute with scientific evidence to clinical practice. The project will analyze the changes in the pattern of the upper limb functional through the use of dynamic and static Orthotics by means of kinematic and electromyographic analysis while conducting a functional task. These comparisons will be carried out with and without the use of functional Orthotics, and the controls are the patients themselves. Methods: 25 patients will be included over 18 years with malfunctions resulting from orthopaedic trauma and Burns of the upper limb with indication and Orthotics for improving functional pattern. For characterization of the sample will be performed: esthesiometric , hand and the (Disabilities of the Arm, Shoulder and Hand) DASH Questionnaire. Biomechanical assessment will be used for the analysis and electromyographic kinematics. For statistical analysis will be applied the method of analysis of variance (ANOVA) for repeated measures, and when necessary, the post hoc Bonferroni test. Will be adopted as significance level p ≤ 0.05.
