Filter by:This study aims to evaluate the effects of whole-body electrical stimulation (WB-EMS) in the rehabilitation of patients undergoing lung transplantation. This is a randomized clinical trial with patients from the inpatient unit of Dom Vicente Scherer Hospital of Irmandade Santa Casa de Misericórdia from Porto Alegre (ISCMPA) who will be allocated to a control group (which will receive physiotherapy from routine) or intervention group (which will receive physiotherapy from routine and WB-EMS). Interventions with WB-EMS will occur every day from the moment of extubation until hospital discharge (15 sessions per patient). Assessments will be carried out pre-lung transplantation, after extubation, during intervention protocols and at the time of hospital discharge.
Chronic kidney disease (CKD) consists of kidney damage, with a consequent progressive and irreversible loss of kidney function. In the early stages of the disease, there is already a reduction in circulating levels of α-klotho protein, which is related to worsening renal function. Therapeutic strategies that increase serum α-klotho levels can be of great value in the treatment of CKD. Electrical stimulation contributes to the reduction of reactive oxygen species, DNA damage and improves the efficiency rate of dialysis, suggesting a systemic effect in patients with end-stage CKD. The aim of this study is to evaluate the effects of bioelectric stimulation on renal function and physical capacity in patients with CKD. For this, patients will be randomized into bioelectric stimulation or a control group. Bioelectric stimulation will be performed three times a week for eight weeks. The control group will only be evaluated and re-evaluated. The following pre-and post-intervention assessments will be performed: analysis of the plasma content of α-Klotho and soluble creatinine to assess renal function, six-minute walk test to assess functional capacity; dosage of interleukins and tumor necrosis factor to analyze the inflammatory profile; sit and stand test with 10 repetitions and load cell dynamometry to assess lower limb muscle strength and application of the EuroQoL-5D questionnaire for quality of life. Biochemical analyzes for renal function and inflammatory profile will also be performed after four weeks of follow-up.
The aim of this research project is to quantify the uncertainty of current state-of-the art anatomical phantoms and computational models for predicting neurostimulation induced by time-varying magnetic fields (so-called gradient fields) within the context of magnetic resonance imaging (MRI) scanners. For this purpose stimulation thresholds will be measured in a volunteer study. The measurements will provide valuable data for the development and validation of future models.
This study aims to evaluate the effects of electrical stimulation on renal function and physical capacity in patients with chronic kidney disease (CKD). This is a randomized controlled trial with patients from the HD outpatient of Santa Clara hospital at Irmandade Santa Casa de Misericórdia de Porto Alegre (ISCMPA), who will be allocated to a control group (it will be evaluated and reassessed) or intervention group (it will receive electrical stimulation). Interventions will occur during the HD session, twice a week, for eight weeks, totaling 16 sessions. The groups will be evaluated prior to physiotherapy intervention and at the end. The following outcomes will be measured: renal function, functional capacity, muscle strength of lower limbs and quality of life.
Pulmonary transplantation aims to increase patient survival and quality of life in relation to functional aspects. It is observed that the decrease in muscle mass and pulmonary changes are some complications that can be found in the post-transplant patient due to immobility. Thus, Neuromuscular Electrical Stimulation (NMES) rehabilitation is of paramount importance for the recovery of the individual, both in the functional aspects, and in the minimization in the time of hospitalization.The objective of this study was to evaluate the effects of NMES on the thickness and strength of the quadriceps femoris muscle, pulmonary function, endothelial function, functional capacity, muscle biochemical markers, arterial blood gas analysis and water balance of patients after lung transplantation through a randomized clinical trial. Patients will be randomized into two groups: EENM group: will receive the application of NMES associated with physiotherapy and control group: who will receive only the physiotherapy protocol of the Hospital of Clinics of Porto Alegre (HCPA) and Irmandade da Santa Casa de Misericórdia de Porto Alegre.
The relationship between the target effect site concentration of remifentanil and the pupil diameter and reactivity in response to a standard noxious stimulus in cardiac surgery during extra corporeal circulation will be evaluated.
Stroke is one of the leading causes of serious long-term impairment. According to the estimates, 12,500 people suffer a new or recurrent ischemic stroke in Chile annually, which shows the magnitude of the problem. Motor impairment of the upper limb (UL) stands out as the principal sequel after a CVA (50% of the patients experience it), and the Constraint-Induced Movement Therapy (CIMT) is the rehabilitation approach that shows more scientific evidence today. Even though patients reach certain recuperation levels through this approach, results are still insufficient since 50-80% of the patients continue having upper limb motor impairment after completing standard rehabilitation. Because of this, it is pertinent to conduct research to explore new rehabilitation strategies to reduce the impairment indexes and to provide information for decision making based on evidence. Recent studies on functional neuroimaging propose that there is an abnormal balance in the motor cortex excitability after stroke - relative under-excitability in the affected hemisphere and over-excitability in the unaffected hemisphere (with the consequent inhibitory influence on ipsilesional regions) in stroke patient with moderate motor impairment. This imbalance in the hemispheres function would limit the possibilities of a greater recovery. Then, in order to reestablish brain balance, the investigators proposed that the early introduction of noninvasive techniques of brain stimulation, such as tDCS, to the motor rehabilitation training could promote improvement of upper limb function in patients with stroke. However, we lack studies that confirm the benefits of using these techniques, define the most appropriate protocols, and determine what patients and under which evolving stages would be the best candidates for treatment. This study aims to "compare the effectiveness of seven days of bi-hemispheric tDCS, both active and sham, combined with modified CIMT (mCIMT) in the motor and functional recovery of the hemiparetic upper limb in hospitalized patients with subacute unihemispheric stroke at Hospital Clínico de la Universidad de Chile and Hospital San José". This comparison responds to the hypothesis that patients who receive bi-hemispheric and active tDCS combined with mCIMT (experimental group) get at least 30% more recovery of the paretic upper limb compared to the control group who receive sham bi-hemispheric tDCS plus mCIMT after a protocol of seven days treatment.
The purpose of this study is to determine whether the transcutaneous application of unmodulated high frequency alternating currents could produce a quickly conduction block of peripheral nerve.
The primary objective of this study is to determine whether neuromuscular electrical stimulation applied to the abdominal wall muscles in synchrony with exhalation can increase the strength of the respiratory muscles in prolonged mechanical ventilation patients.
The purpose of this study is analyze the immediate effect of selective neuromuscular electrical stimulation of vastus medialis obliquus (VMO) in the electrical activity of VMO and vastus lateralis (VL) and in the isokinetic performance of women with patellofemoral pain syndrome.
