Test−Retest Reliability and Convergent Validity of Three Manual Dexterity Measures in Persons With Chronic Stroke
Conclusion The test−retest reliability of the BBT, NHPT and mSHFT was high but all measures showed learning effects. The relationships between the 3 measures indicate that they partly complement one another. The BBT may be preferred for persons with moderate impairments of the upper extremity and the NHPT and the mSHFT for persons with milder impairments. As the mSHFT has the advantage of reflecting activities in daily life it may be a suitable alternative to the NHPT.

A lesion to learn: Stroke mimics
Publication date: Available online 26 March 2016 Source:Apollo Medicine Author(s): Mahir Meman, Pushpendra Nath Renjen, Dinesh M. Chaudhari Acute ischemic stroke with neurological deficit is a very debilitating condition, especially in younger patients. IV thrombolysis is the only effective treatment available in most of the centers across India. But delay in hospitalization and bleeding complications are major limitations. In addition to that, stroke mimics are another big problem. Correct identification of stroke mimics needs clinical expertise and imaging studies. Multiple studies indicate safety of thrombolysis in...

Computer Imagery and Neurological Rehabilitation: On the Use of Augmented Reality in Sensorimotor Training to Step Up Naturally Occurring Cortical Reorganization in Patients Following Stroke.
Authors: Correa-Agudelo E, Ferrin C, Velez P, Gomez JD Abstract This work promotes the use of computer-generated imagery -as visual illusions- to speed up motor learning in rehabilitation. In support of this, we adhere the principles of experience-dependent neuroplasticity and the positive impact of virtual reality (VR) thereof. Specifically, post-stroke patients will undergo motor therapy with a surrogate virtual limb that fakes the paralyzed limb. Along these lines, their motor intentions will match the visual evidence, which fosters physiological, functional and structural changes over time, for recovery of lost...

High blood pressure: Why me?
“I go to the gym, and I never add salt. So why do I have high blood pressure?” Despite its astonishing prevalence of one in three Americans, many people struggle with the diagnosis of high blood pressure, or hypertension. It’s worth exploring why, because being an active participant in your care is crucial for optimal blood pressure control. Certain features make any diagnosis easier to accept: First, people are more likely to accept a diagnosis if they have symptoms. A person with cough and fever will believe a diagnosis of pneumonia. But someone who feels fine would not. Next, people more readily accept a diagnosi...

Alpha-linolenic acid given as enteral or parenteral nutritional intervention against sensorimotor and cognitive deficits in a mouse model of ischemic stroke.
This study evaluated the value of ALA as adjunctive therapy for stroke recovery by comparing whether oral or intravenous supplementation of ALA best support recovery from ischemia. Motor and cognitive deficits were assessed using rotarod, pole and Morris water maze tests. ALA supplementation in diet was better than intravenous treatment in improving motor coordination, but this improvement was not due to a neuroprotective effect since infarct size was not reduced. Both types of ALA supplementation improved spatial learning and memory after stroke. This cognitive improvement correlated with higher survival of hippocampal ne...

Neurological Recovery of Upper Extremity in Stroke Woman after 5 Years: A Case Report.
This report describes the case of a stroke patient who gained upper extremity motor recovery after 5 years, which is beyond the normal recovery period. Although the patient does not have functionality, she has partial motor recovery, and she is enthusiastic about learning to gain better use of her hand. However there is still limited evidence to use in designing effective intervention and proper timing of rehabilitation administered by personnel in training chronic stroke patients. Therefore, evidence based on neuroplasticity and neurological recovery in chronic stroke patients, including rehabilitation intervention, is pr...

For the good of your heart: Keep holding the salt
Your doctor has probably told you to cut back on salt, especially if you have high blood pressure. For years we’ve understood that excess salt raises blood pressure and increases deaths from heart disease. The guilty element is sodium, which pairs with chloride to form common salt. So when the journal Lancet recently published a study reporting that low dietary sodium was associated with an increased risk of heart disease and death, controversy was predictable. A wealth of rigorous scientific studies supports a link between excess sodium intake and high blood pressure, heart attacks, and strokes. Yet the Lancet paper rep...

Neurofeedback-based motor imagery training for rehabilitation after stroke.
Abstract Mental training, including motor observation and motor imagery, has awakened much academic interest. The presumed functional equivalence of motor imagery and motor execution has given hope that mental training could be used for motor rehabilitation after a stroke. Results obtained from randomized controlled trials have shown mixed results. Approximately half of the studies demonstrate positive effects of motor imagery training but the rest do not show an additional benefit. Possible reasons why motor imagery training has so far not become established as a robust therapeutic approach are discussed in detai...

Effects of thalamic hemorrhagic lesions on explicit and implicit learning during the acquisition and retrieval phases in an animal model of central post-stroke pain.
Abstract Hemorrhagic stroke has many symptoms, including central pain, learning and memory impairments, motor deficits, language problems, emotional disturbances, and social maladjustment. Lesions of the ventral basal complex (VBC) of the thalamus elicit thermal and mechanical hyperalgesia, forming an animal model of central post-stroke pain (CPSP). However, no research has yet examined the involvement of learning and memory in CPSP using an animal model. The present study examined whether VBC lesions affect motor function, conditioned place preference (CPP; implicit memory), and spatial learning (explicit memory)...

Analysis of Balance during Functional Walking in Stroke Survivors
DiscussionWe developed and demonstrated a method to assess walking balance of stroke survivors. System design and evaluation methods allow balance evaluation during functional walking in daily life. Some presented metrics show correlations with BBS scores. Clear inter- and intra-patient variations in metric values are present that cannot be explained by BBS scores, which supports the additional value of the presented system. Presented methods may be used for objective evaluation of restitution and compensation of walking balance and have a potential application in individual evidence-based therapy.

Stroke Risk Stratification and its Validation using Ultrasonic Echolucent Carotid Wall Plaque Morphology: A Machine Learning Paradigm
Stroke risk stratification based on grayscale morphology of the ultrasound carotid wall has recently been shown to have a promise in classification of high risk versus low risk plaque or symptomatic versus asymptomatic plaques. In previous studies, this stratification has been mainly based on analysis of the far wall of the carotid artery. Due to the multifocal nature of atherosclerotic disease, the plaque growth is not restricted to the far wall alone. This paper presents a new approach for stroke risk assessment by integrating assessment of both the near and far walls of the carotid artery using grayscale morphology of the plaque.

Stroke accounts for one in every 20 deaths in the U.S., and someone dies of stroke in the U.S. every four minutes.1 One third of people who have had a stroke will be left with some degree of long-term disability.2 Eighty-seven percent of all strokes are ischemic, meaning that a clot or other occlusion to blood flow forms within an intracranial vessel, depriving the brain tissue of blood flow.1 If this obstruction isn't rapidly relieved, damage to the brain will occur.

Explicit motor sequence learning with the paretic arm after stroke.
CONCLUSIONS: Stroke survivors can learn a movement sequence with their paretic arm, but demonstrate impairments in sequence specific learning. Implications for Rehabilitation Motor sequence learning is important for recovery of movement after stroke. Stroke survivors were found to be capable of learning a movement sequence with their paretic arm, supporting the concept of repetitive task training for recovery of movement. Stroke survivors showed impaired sequence specific learning in comparison with age-matched controls, indicating that they may need more repetitions of a sequence in order to re-learn movements. Further re...

Predicting Motor Sequence Learning in Individuals With Chronic Stroke
Conclusion. Nonlinear information extracted from multiple time points across practice, specifically the rate of motor skill acquisition during practice, relates strongly with changes in motor behavior at the retention test following practice and could be used to predict optimal doses of practice on an individual basis.

Can Motor Recovery in Stroke Be Improved by Non-invasive Brain Stimulation?
Authors: Rothwell JC Abstract At the present time, there is enormous interest in methods of non-invasive brain stimulation. These interact with ongoing neural activity, mainly in cerebral cortex, and have measureable effects on behaviours in healthy people. More intriguingly, they appear to have effects on synaptic plasticity that persist even after stimulation has ceased. This has led, as might be expected, to the proposal that brain stimulation methods might be therapeutically useful in rehabilitation. The rationale is that physical therapy involves learning new patterns of activity to compensate for those lost t...
