Effect of Visual Art School–Based Stroke Intervention for Middle School Students
ABSTRACT: Background: Community stroke awareness initiatives have traditionally been used to expand knowledge of stroke signs and risk factors to high-risk adult populations. Here, we use a novel unfettered, visual art–based approach for an elementary school initiative to raise stroke awareness. Methods: Seventh graders in a middle school art class received stroke awareness training during the course of the 2015 to 2016 school year through their teacher in the visual arts class. In turn, they used this training to develop their own artistic interpretations of key stroke awareness concepts via project-based learning and t...

Temporal Features of Muscle Synergies in Sit-to-Stand Motion Reflect the Motor Impairment of Post-Stroke Patients
Sit-to-stand (STS) motion is an important daily activity, and many post-stroke patients have difficulty performing STS motion. Previous studies found that there are four muscle synergies (synchronized muscle activations) in the STS motion of healthy adults. However, for post-stroke patients, it is unclear whether muscle synergies change and which features primarily reflect motor impairment. Here, we use a machine learning method to demonstrate that temporal features in two muscle synergies that contribute to hip rising and balance maintenance motion reflect the motor impairment of post-stroke patients. Analyzing the muscle...

Effects of Cerebellar Transcranial Direct Current Stimulation in Patients with Stroke: a Systematic Review
CONCLUSIONS: ctDCS appears to improve poststroke language and motor dysfunction (particularly gait). However, the evidence for these results was insufficient, and the quality of the relevant studies was low. ctDCS stimulation parameters and individual factors of participants may affect the therapeutic effect of ctDCS. Researchers need to take a more regulated approach in the future to conduct studies with large sample sizes. Overall, ctDCS remains a promising stroke intervention technique that could be used in the future.PMID:36028789 | DOI:10.1007/s12311-022-01464-7

Impaired implicit learning and feedback processing after stroke
Publication date: 9 February 2016 Source:Neuroscience, Volume 314 Author(s): J.M. Lam, C. Globas, J.A. Hosp, H.-O. Karnath, T. Wächter, A.R. Luft The ability to learn is assumed to support successful recovery and rehabilitation therapy after stroke. Hence, learning impairments may reduce the recovery potential. Here, the hypothesis is tested that stroke survivors have deficits in feedback-driven implicit learning. Stroke survivors (n =30) and healthy age-matched control subjects (n =21) learned a probabilistic classification task with brain activation measured using functional magnetic resonance imaging in a subse...

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.

Moderate-intensity cardiovascular exercise performed before motor practice attenuates offline implicit motor learning in stroke survivors but not age-matched neurotypical adults
Exp Brain Res. 2023 Jul 3. doi: 10.1007/s00221-023-06659-w. Online ahead of print.ABSTRACTThe acute impact of cardiovascular exercise on implicit motor learning of stroke survivors is still unknown. We investigated the effects of cardiovascular exercise on implicit motor learning of mild-moderately impaired chronic stroke survivors and neurotypical adults. We addressed whether exercise priming effects are time-dependent (e.g., exercise before or after practice) in the encoding (acquisition) and recall (retention) phases. Forty-five stroke survivors and 45 age-matched neurotypical adults were randomized into three sub-group...

Reply to “The effects of functional electrical stimulation on upper extremity function and cortical plasticity in chronic stroke patients”
I appreciate the very important and developed suggestions by Dr. Cecatto for our article (). The proposals on the reasons why EMG-controlled FES (EMG–FES) could shift the brain hemispheric-dominant perfusion in our study provided our study further development and progress. The motor output and corresponding muscle and joint proprioceptive feedback may be tightly coupled and coordinated with movement by EMG–FES. As Dr. Cecatto proposed, these neural reorganisation mechanisms should be explored. The sensory components of large afferent fibre activation, proprioceptive input and increased cognitive sensory attention are a...

Pharmacological Enhancement of Stroke Recovery
AbstractPurpose of ReviewThis review aims to discuss the recent literature relating to drugs for stroke recovery and to identify some of the challenges in conducting translational research for stroke recovery.Recent FindingsAdvances in our understanding of neural repair mechanisms in pre-clinical stroke models have provided insights into potential targets for drugs that enhance the repair/recovery process. Few drugs that act on serotonergic and dopaminergic systems have been tested in humans with mixed results. The FOCUS trial, a phase III study of early administration of fluoxetine for stroke recovery, failed to replicate...

Lost in Translation: Simple Steps in Experimental Design of Neurorehabilitation-Based Research Interventions to Promote Motor Recovery Post-Stroke
Stroke continues to be a leading cause of disability. Basic neurorehabilitation research is necessary to inform the neuropathophysiology of impaired motor control, and to develop targeted interventions with potential to remediate disability post-stroke. Despite knowledge gained from basic research studies, the effectiveness of research-based interventions for reducing motor impairment has been no greater than standard of practice interventions. In this perspective, we offer suggestions for overcoming translational barriers integral to experimental design, to augment traditional protocols, and re-route the rehabilitation tr...

Evaluation of Postural Sway in Post-stroke Patients by Dynamic Time Warping Clustering
This study instead evaluates the postural sway features of post-stroke patients using the clustering method of machine learning. First, we collected the stroke patients' multi-variable motion-capture standing-posture data and processed them into t s long data slots. Then, we clustered the t-s data slots into K cluster groups using the dynamic-time-warping partition-around-medoid (DTW-PAM) method. The DTW measures the similarity between two temporal sequences that may vary in speed, whereas PAM identifies the centroids for the DTW clustering method. Finally, we used a post-hoc test and found that the sway amplitudes of mark...
