Filter by:Previous studies found important function of brain in exercises regulation on healthy and athlete patients and this studies showed not invasive stimulation on temporal cortex brain, induces electrics field to insula cortex, in addition modulate autonomic nervous system cognition efforts during submaximal (maximal hight frequency) and maximal exercises. Measure immediate effects of transcranial stimulation in bloodstream (tDCS) anodic on right and left temporal cortex in the cardiorespiratory parameters (functional capacity, perception of efforts and modulation of autonomic nervous system) in patients with hemiparesis due stroke. Methods and Material: It Is a clinical trial, controlled and Double blind, using 30 adult patients with stroke sequel, like roam. Evaluation will be hemodynamic measure data such as: Heart Rate, Respiratory Rate, Blood Pressure, Lung Capacity Vital and assessment of the Autonomic Nervous System, before and after anodic electro stimulation from bloodstream on right and left temporal cortex region (T3 area) and cathodic position in contralateral supraorbital region to anode (Fp2). On temporal cortex will be applied of 2mA during stimulation of 20 minutes. Sham stimulation all electrodes Will be used. The stimulator turns on for 30 seconds. Results: The primary results will analyze cardiac frequency before and after tDCS and second step will assess the travelled distance on walking test for 6 minutes with and without tDCS and compare these respiratory reviews results with stroke gravity.
The purpose of this multicenter study is to investigate the extra-/intra-cranial atherosclerosis distribution pattern in chinese populations with transient ischemic attack and ischemic stroke and analyze the influencing factors of atherosclerosis distribution pattern.
This is a phase one study investigating the safety of a single, intravenous infusion of banked allogeneic umbilical cord blood in subjects following an acute ischemic stroke. The cord blood infusion must be given within 3-10 days of the stroke. Follow up phone calls will occur at 1, 6, and 12 months post-infusion, and will include telephone surveys on post-stroke rehabilitation and functioning. A follow up clinic visit at 90 days will include a neurological exam, MRI, and blood tests.
Stroke is one of the most serious, disabling health conditions in the United States. Patients who undergo rehabilitation treatment for stroke have a high rate of disability. Poor outcomes for many persons with stroke may be low because of incomplete treatment. The investigators will conduct a randomized controlled trial and a process evaluation to examine the feasibility, safety, and preliminary efficacy of an enhanced rehabilitation transition program, Community Participation Transition after Stroke (COMPASS), designed to bridge inpatient rehabilitation and the home to support the performance of everyday activities.
Double blind, randomized, placebo control, multiple dose, dose escalation study
To study the effect of combined tDCS plus speech therapy compared to sham-tDCS plus speech therapy in subacute stroke patients suffering from moderate or severe aphasia. The patients will be randomized by a computer-generated lot. Assessment will be performed at study onset, after six weeks at the end of the specific intervention and 4 months after stroke onset for follow-up.
Rationale: About 80% of stroke patients suffer motor impairments, but current therapies have limited effects on motor recovery. Therefore, investigating new potential therapeutic approaches is crucial. Transcranial Direct Current Stimulation (tDCS) is a form of non-invasive electrical stimulation where a weak current is applied through electrodes over the scalp. This stimulation is known to (1) induce changes in neuronal excitability -which can last up to one day with late LTP-like plasticity protocols in a polarity and site-specific manner, and (2) facilitate motor learning and stroke recovery. So far, several pilot studies have reported beneficial results from tDCS in both subacute and chronic stroke patients, but it's still unclear how tDCS should be repeated over multiple days to optimally enhance recovery and training effects. Using a late LTP-like plasticity protocol could increase effectiveness of standard clinical care rehabilitation sessions and thus enhance the effects of rehabilitation. Therefore, the investigators want to investigate how late LTP-like plasticity tDCS affects rehabilitation in subacute stroke patients. The outcome of this study can provide important guidelines on effective motor therapy during stroke rehabilitation. Objective: Identify the effect of late LTP-like plasticity on motor rehabilitation during the subacute phase after stroke. Study design: Double-blinded, randomized between-subjects trials. Study population: Subacute stroke patients. Main study parameters/endpoints: The primary outcome measure is the upper limb motor function during the subacute phase after stroke.
Stroke disease and cognitive impairment are common in patients established on haemodialysis (HD) for end-stage renal disease (ESRD). Further, initiation of HD appears to transiently increase the risk of stroke. The mechanism by which this occurs is not known. Using ultrasound, patient questionnaires and brain MRI our study will observe changes in cognition and cerebral blood flow whilst receiving HD compared to a non-dialysis day. Transient clinical and ultrasound alterations will be correlated to radiographic changes in cerebral perfusion and structure on MRI to determine the underlying mechanism for the increased stroke risk. The investigators will observe this effect in the immediate and longer term (12 months observation). A greater understanding will allow development of effective preventive strategies.
On-going rehabilitation is needed to maintain and improve the weaker upper extremity following stroke. Community rehabilitation programs for stroke individuals in the chronic stage are often difficult to be implement. Consequently, many individuals remain without structured interventional programs. Self-training programs, where individuals can independently continue to exercise at home, might answer this challenge. However, since exercising alone is boring and not motivating, individuals often stop the prescribed exercises and remain inactive. The use of video-games for self-training might answer this challenge. Therefore, the investigators aimed to assess the feasibility of using video-games for self-training after stroke. Specifically the investigators aim to compare the (1) training time, (2) satisfaction and (3) effectiveness of a self-training program using video-games compared to a traditional self-training program.
The stroke is the second cause of death and the first of disabilities in the world. Although a motor spontaneous recovery is observed, around 50 to 70% of the hemiparetic upper extremity present alterations of upper extremity, limiting the performance of daily activities even after 2 to 4 years of strokes. More recently used in neurological rehabilitation, the ability to promote sensory-motor facilitation is given to the Elastic Tape (ET). However, its safety and efficacy in the treatment of post-stroke individuals still require further investigation. Thus, the objective of this project is to evaluate the immediate effects of ET, applied to the paretic shoulder on proprioception during movements of abduction and flexion of the shoulder and muscle activation and kinematic variables for the reaching in chronic hemiparetic. Fifteen subjects with chronic hemiparesis will participate these crossover sham-controlled trial. Participants will be randomized into two condition: elastic tape (ET) followed by sham tape (ST- strapping) or ST followed by ET. One month of washout period was considered. The motor impairment and the dominance before stroke will be evaluated by Fugl-Meyer scale and the Inventory Side dominance of Edinburgh, respectively. ET will apply deltoid (anterior, middle and posterior). Assessment before and after the application of ET will be performed. For proprioception assessment (joint position sense) will be evaluated using a dynamometer. Absolute error for shoulder abduction and flexion at the 30° and 60° was calculated. For the assessment of motor performance in a functional task (reach a glass of water), spatio-temporal parameters (total duration of the motion, peak velocity, time to peak velocity) and three-dimensional joint kinematics of the trunk, scapula, shoulder, and elbow (total range of motion, joint angle maximum and minimum) will be used. Concomitantly, bilateral activation of the deltoid (anterior, middle and posterior), trapezius (upper and lower), serratus anterior and pectoral major will be assessed by electromyography during reach. The following electromyographic variables will be analyzed: activation amplitude, muscle onset and maximum and minimum activation. For statistical analysis, the normality and homogeneity tests will be applied. If the variables have a distribution considered normal and homogeneous, Two-way ANOVA with repeated measures gift will be applied. Otherwise it will be applied to non-parametric statistics Friedman. Will be considered a 0.05 significance level for all statistical tests.
