Filter by: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.
The main objective of this research is to demonstrate that the use of insoles of different hardness in motorcycle riders may cause variations in the electromyographic activity of the lower limb muscles during the race. This study is a cross-over quasi-experimental study. Nine motorcycle riders were recruited. Electromyographic activity of the lower limb muscles is recorded under different insole types.
Chronic pelvic pain (CPP) is a common presenting complaint affecting approximately 15-40 % of women aged 18-50 in western countries and 5-43% of women in most developing countries. It is debilitating and has a large socio- economic impact, with a 45%reduction in work productivity, and a 15% increase in absence from work in women with the condition. Botulinum neurotoxin type A (BoNTA) has been suggested to improve pain in muscle spasm, its role in CPP secondary to pelvic floor spasm has gained increasing interest. However, clinicians do not have a diagnosis tool to evaluate the CPP and the BoNTA treatment results. Design and develop an efficient and simple tool for the diagnosis and detection of pelvic floor muscle (PFM) dysfunction based on superficial electromyography (EMG) and perform 25 EMG registrations sessions in healthy patients and 25 EMG sessions in patients diagnoses with PFM that will be treated with BoNTA to and study the EMG signal before and after BoNTA administration.
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 aim of this study was to assess the effect of a specific protocol of sEMG-BFB in upper limb hemiparesis added to conventional physical therapy on changes in upper extremity functionality, motor recruitment pattern and range of motion (ROM) compared to the single application of conventional physical therapy. It aims to find a 22.22% difference between both interventions.
A cross-sectional descriptive study, in which the surface electromyographic activity of five shoulder muscles was compared in three populations: older adults, middle-aged adults and young adults. The evaluation of the electromyographic data offers a suitable foundation to understand aging process. This supports that surface electromyography provide information about the aged shoulder muscles. Loss of functionality is suffered by a high percentage of older adults, which greatly limits their physical activity. In this sense, this paper presents findings that might be related with possible therapeutic approaches in subsequent studies.
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.
TetraGraph is a newly developed EMG-based (electromyograph), quantitative, battery-powered neuromuscular monitoring system intended for daily clinical use. The primary aim of this clinical investigation is to examine the applicability (ease of use, equipment need, etc.), repeatability (precision or internal consistency) and performance (signal quality, accuracy of outcome, voltage of stimulation output before and during a stimulus) and tolerability of the Tetragraph device in healthy volunteers.
It was recently shown that neostigmine reversal was associated with increased atelectasis and that high-dose neostigmine was associated with longer postoperative length of stay and with an increased incidence of pulmonary edema and reintubation. These study results were consistent with findings from a previous epidemiological study which revealed an absence of beneficial effects of neostigmine on postoperative oxygenation and reintubation. In our previous study, the effects of neostigmine / glycopyrrolate and sugammadex on the electromyographic activity of the diaphragm showed beneficial effects for sugammadex. This could be explained by a possible effect on neuromuscular transmission at the muscle level, but can also be explained by a neostigmine-induced decrease in total nerve activity. In a study in cats, neostigmine has been shown to reduce efferent phrenic nerve activity. The investigators aim to show a difference in phrenic nerve activity between neostigmine and sugammadex, administered alone or in combination, in healthy male volunteers.
