The objective of this review is to provide an evidence-based summary of stroke incidence, risk factors, prevention, and treatment of stroke in pregnancy. The impact of postpartum contraceptive use can on stroke risk is summarized.
In this study, ovariectomized rats were treated with genistein (10 mg/kg) or vehicle daily for two weeks before they received middle cerebral artery occlusion (MCAO) and reperfusion. After 72 hours of reperfusion, the neurological function was evaluated by Garcia test, infarct volume was detected by 2,3,5-triphenyltetrazolium chloride staining, and neuronal damage was detected by Nissl staining. In addition, ROS production and the expression of Nrf2, NQO1 and cleaved-Caspase3 in the ischemic penumbra were detected. RESULTS: The results showed that genistein treatment significantly improved the neurological outcome, red...
Atrial fibrillation (AF) can be newly-diagnosed in up to 24% of patients with ischemic stroke . The entity so called “AF detected after stroke” (AFDAS) has been created to acknowledge the complexity of diagnosing and managing these patients . AFDAS may be a pre-existing AF condition that is unknown and/or asymptomatic, and is only diagnosed because of thorough post-stroke electrocardiographic monitoring in a yet unknown proportion of patients. Conversely, it may also be the consequence of neurogenic AF mechanisms triggered by the presence of a stroke.
It is unclear whether ischemic stroke patients with known atrial fibrillation (KAF) had different outcomes than those with atrial fibrillation diagnosed after stroke (AFDAS). We aimed to explore the characteristics and outcomes in ischemic stroke patients with KAF or AFDAS.
The purpose of this study was to verify the influence of lower limb orthoses on muscle synergy control during gait in stroke patients with hemiparesis. In four subjects with acute stroke, surface EMG signals from eight muscles of the paretic lower limb were measured during gait in two conditions (ankle foot orthosis; AFO or knee ankle foot orthosis; KAFO). The number of modules, muscle weightings and activation timing profile of each module were analyzed using non-negative matrix factorization. In two subjects (Fugl Meyer Assessment; FMA > 20) who walked with mild assistance, three modules were identified during ga...
We have conducted our research into kinesthetic illusions induced by visual stimuli (KiNvis), which are sensations of being in motion that result from watching artificial images of the body part moving. Our previous studies revealed characteristic neural networks related to KiNvis; since then, we have initiated clinical studies adapting KiNvis in patients with stroke. In patients with severe stroke, it is often difficult to measure joint angles, because voluntary movement does not occur or simultaneous contraction of the agonist and antagonist muscles prevent controlled voluntary joint exercise.
A large number of electroencephalogram-based brain-machine interface (BMI) systems developed by industry and academia are now available for neurorehabilitation. However, the lack of phase 1 –2 clinical trials for BMI interventions to post-stroke hemiplegia has been limited their treatment outcome. To test the safety and feasibility of BMI interventions, we conducted trials with a customly developed BMI system for patients with acute/subacute hemiparetic stroke. Four inpatients partic ipated in this study in the early phase (7–24 days from stroke onset).
Regaining the function of an impaired limb is highly desirable in individuals experiencing paralysis. One possible avenue to achieve this goal is through rewiring of preserved neural structures to bridge the interrupted pathway using a brain-computer interface. Here we demonstrated that monkeys with subcortical stroke were able to learn to use an artificial cortico-muscular connection (ACMC), brain-controlled functional electrical stimulation to the hand muscles, to regain volitional control of a paralyzed hand.
Functional loss of limb control in individuals with spinal cord injury or stroke can be caused by transection of descending pathways those connects cortical to spinal network, although neural circuits locate above and below the impaired site remains their function. I will show an artificial neuronal connection (ANC) that bridges supra-spinal system and spinal network beyond the lesion site restore lost function. The ANC was produced by a computer interface that can detect the neural activity and converted in real-time to activity-contingent electrical stimuli delivered to nervous system.
To examine the effect of the EEG-based brain computer interface (BCI) training for patients with stroke, writer ’s cramp and neuropathic pain. Method: Using the EEG recorded with Ag/AgCl electrodes placed at C3 and C4, as designated according to the International 10/20 system, we gave real time visual feedback to the patients with PC monitor which is placed in front of them. Participants were required to im agine the affected wrist extending in stroke and neuropathic pain patients. Patients with writer’s cramp were requested to relax their wrist flexor while extending their wrist.
