Automated segmentation of chronic stroke lesions using LINDA: Lesion identification with neighborhood data analysis
Abstract The gold standard for identifying stroke lesions is manual tracing, a method that is known to be observer dependent and time consuming, thus impractical for big data studies. We propose LINDA (Lesion Identification with Neighborhood Data Analysis), an automated segmentation algorithm capable of learning the relationship between existing manual segmentations and a single T1‐weighted MRI. A dataset of 60 left hemispheric chronic stroke patients is used to build the method and test it with k‐fold and leave‐one‐out procedures. With respect to manual tracings, predicted lesion maps showed a mean dice overlap of...

Effectiveness of motor imagery or mental practice in functional recovery after stroke: a systematic review
Conclusions MP is effective when used in conjunction with conventional physical therapy for functional rehabilitation of both upper and lower limbs, as well as for the recovery of daily activities and skills. Owing to the heterogeneity of the studies with regard to the intervention protocol, specific imagery technique, time spent practicing, patient characteristics, etc., more studies are needed in order to determine the optimal treatment protocol and patient profile.

The inclination for conscious motor control after stroke: validating the Movement-Specific Reinvestment Scale for use in inpatient stroke patients.
CONCLUSIONS: The MSRS is a valid and reliable tool and suitable to assess the relationship between reinvestment and motor recovery in the first months post-stroke. Eventually, this may help therapists to individualize motor learning interventions based on patients' reinvestment preferences. Implications for rehabilitation This study showed that the Movement-Specific Reinvestment Scale (MSRS) is a valid and reliable tool to objectify stroke patients' inclination for conscious motor control. The MSRS may be used to identify stroke patients who are strongly inclined to consciously control their movements, as this disposition ...

The role of learning in improving functional writing in stroke aphasia.
CONCLUSIONS: These results show that small doses of writing therapy can lead to large gains in specific types of writing. These gains did not extend to improvements in frequency of writing in daily living, nor ecological measures of email writing. There is a need to develop bridging interventions between experimental tasks towards more multi-faceted and ecological everyday writing tasks. Implications for Rehabilitation Acquired dysgraphia can restrict people from participating in social, educational and professional life. This study has shown that copy and recall spelling therapies can improve the spelling of treated words...

Sensors, Vol. 16, Pages 134: A Machine Learning Framework for Gait Classification Using Inertial Sensors: Application to Elderly, Post-Stroke and Huntington’s Disease Patients
Machine learning methods have been widely used for gait assessment through the estimation of spatio-temporal parameters. As a further step, the objective of this work is to propose and validate a general probabilistic modeling approach for the classification of different pathological gaits. Specifically, the presented methodology was tested on gait data recorded on two pathological populations (Huntington’s disease and post-stroke subjects) and healthy elderly controls using data from inertial measurement units placed at shank and waist. By extracting features from group-specific Hidden Markov Models (HMMs) and signal in...

Dorsal premotor activity and connectivity relate to action selection performance after stroke
Abstract Compensatory activation in dorsal premotor cortex (PMd) during movement execution has often been reported after stroke. However, the role of PMd in the planning of skilled movement after stroke has not been well studied. The current study investigated the behavioral and neural response to the addition of action selection (AS) demands, a motor planning process that engages PMd in controls, to movement after stroke. Ten individuals with chronic, left hemisphere stroke and 16 age‐matched controls made a joystick movement with the right hand under two conditions. In the AS condition, participants moved right or left...

Defining Optimal Aerobic Exercise Parameters to Affect Complex Motor and Cognitive Outcomes after Stroke: A Systematic Review and Synthesis.
Abstract Although poststroke aerobic exercise (AE) increases markers of neuroplasticity and protects perilesional tissue, the degree to which it enhances complex motor or cognitive outcomes is unknown. Previous research suggests that timing and dosage of exercise may be important. We synthesized data from clinical and animal studies in order to determine optimal AE training parameters and recovery outcomes for future research. Using predefined criteria, we included clinical trials of stroke of any type or duration and animal studies employing any established models of stroke. Of the 5,259 titles returned, 52 artic...

Modulation of Synaptic Plasticity by Exercise Training as a Basis for Ischemic Stroke Rehabilitation.
Abstract In recent years, rehabilitation of ischemic stroke draws more and more attention in the world, and has been linked to changes of synaptic plasticity. Exercise training improves motor function of ischemia as well as cognition which is associated with formation of learning and memory. The molecular basis of learning and memory might be synaptic plasticity. Research has therefore been conducted in an attempt to relate effects of exercise training to neuroprotection and neurogenesis adjacent to the ischemic injury brain. The present paper reviews the current literature addressing this question and discusses ...

Progesterone improves long-term functional and histological outcomes after permanent stroke in older rats.
Abstract Previous studies have shown progesterone to be beneficial in animal models of central nervous system injury, but less is known about its longer-term sustained effects on recovery of function following stroke. We evaluated progesterone's effects on a panel of behavioral tests up to 8 weeks after permanent middle cerebral artery occlusion (pMCAO). Male Sprague-Dawley rats 12m.o. were subjected to pMCAO and, beginning 3h post-pMCAO, given intraperitoneal injections of progesterone (8mg/kg) or vehicle, followed by subcutaneous injections at 8h and then every 24h for 7 days, with tapering of the last 2 treatme...

The role of auditory feedback in music-supported stroke rehabilitation:A single-blinded randomised controlled intervention.
CONCLUSIONS: Auditory feedback-based motor learning is not the beneficial mechanism of music-supported therapy. Immediate auditory feedback therapy may be suboptimal. Jittered delay may increase efficacy of the proposed therapy and allow patients to fully benefit from motivational factors of music training. Our study shows a novel way to test hypotheses concerning music training in a single-blinded way, which is an important improvement over existing unblinded tests of music interventions.

A Remote Quantitative Fugl-Meyer Assessment Framework for Stroke Patients Based on Wearable Sensor Networks
To extend the use of wearable sensor networks for stroke patients training and assessment in non-clinical settings, this paper proposes a novel remote quantitative Fugl-Meyer assessment (FMA) framework, in which two accelerometer and seven flex sensors were used to monitoring the movement function of upper limb, wrist and fingers. The extreme learning machine based ensemble regression model was established to map the sensor data to clinical FMA scores while the RRelief algorithm was applied to find the optimal features subset.

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 three 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.

Reports Ipsilesional anodal tDCS enhances the functional benefits of rehabilitation in patients after stroke
Anodal transcranial direct current stimulation (tDCS) can boost the effects of motor training and facilitate plasticity in the healthy human brain. Motor rehabilitation depends on learning and plasticity, and motor learning can occur after stroke. We tested whether brain stimulation using anodal tDCS added to motor training could improve rehabilitation outcomes in patients after stroke. We performed a randomized, controlled trial in 24 patients at least 6 months after a first unilateral stroke not directly involving the primary motor cortex. Patients received either anodal tDCS (n = 11) or sham treatment (n = 13) paired wi...

Brain activation is related to smoothness of upper limb movements after stroke.
This study suggests that recruitment of secondary motor areas at 6 weeks after stroke is highly associated with increased jerk during reaching and grasping. As jerk represents the change in acceleration, the recruitment of additional sensorimotor areas seems to reflect a type of control in which deviations from an optimal movement pattern are continuously corrected. This relationship suggests that additional recruitment of sensorimotor areas after stroke may not correspond to restitution of motor function, but more likely to adaptive motor learning strategies to compensate for motor impairments.

Procedural learning as a measure of functional impairment in a mouse model of ischemic stroke.
Abstract Basal ganglia stroke is often associated with functional deficits in patients, including difficulties to learn and execute new motor skills (procedural learning). To measure procedural learning in a murine model of stroke (30min. right MCAO), we submitted C57Bl/6J mice to various sensorimotor tests, then to an operant procedure (Serial Order Learning) specifically assessing the ability to learn a simple motor sequence. Results showed that MCAO affected the performance in some of the sensorimotor tests (accelerated rotating rod and amphetamine rotation test) and the way animals learned a motor sequence. Th...

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...

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...
