“…5,6 It comprises the repeated practice of motor (or kinaesthetic) imagery. 7 During MP participants are typically guided to cognitively rehearse, but not physically perform, movements of the upper-limb often to complete a functional task 8,9 or to consider how one might perform a task (e.g. grip a cup).…”

Objective: This systematic review sought to determine the effectiveness of mental practice (MP) upon the activity limitations of the upper-limb in people after stroke, and when, in whom and how it should be delivered. Data sources: Ten electronic databases were searched from November 2009 to May 2020. Search terms included: Arm; Practice; Stroke Rehabilitation; Imagination; Paresis; Recovery of Function; Stroke Studies from a Cochrane review of MP (up to November 2009) were automatically included. The review was registered with Prospero database of systematic reviews (Reference number: CRD42019126044). Study selection: Randomised controlled trials of adults after stroke using MP for the upper-limb were included if they compared to usual care, conventional therapy or no treatment and reported activity limitations of the upper-limb as outcomes. Independent screening was carried out by two reviewers. Data extraction: One reviewer extracted data using a tool based upon the Template for Intervention Description and Replication. Data extraction was independently verified by a second reviewer. Quality was assessed using the PEDro tool.Data Synthesis: Fifteen studies (n=486) were included and 12 (n=328) underwent meta-analysis. MP demonstrated significant benefit upon upper-limb activities compared to usual treatment (standardised mean difference, SMD: 0.6, 95% 4 confidence intervals, CI: 0.32 to 0.88). Sub-group analyses demonstrated that MP appeared most effective in the first 3 months after stroke (SMD: 1.01, 95% CI: 0.53 to1.50) and in people with the most severe upper-limb deficits (weighted mean difference, WMD: 7.33; 95% CI:0.94 to 13.72). Conclusions:This review demonstrates that MP appears effective in reducing activity limitations of the upper-limb after stroke particularly in people in the first three months after stroke and in those with the most severe upper-limb dysfunction. There was no clear pattern of the ideal dosage of MP.

“…Electroencephalograph (EEG)-based BCI systems is often applied in combination with motor imagery (MI) paradigm ( Alkadhi et al, 2005 ) for neurorehabilitation training ( Kumar et al, 2016 ; Baig et al, 2017 ; Oikonomou et al, 2017 ; Cheng et al, 2018 ), especially for enhancing motor recovery from brain injuries such as stroke hemiplegia ( Buch et al, 2008 ; Zimmermann-Schlatter et al, 2008 ; Daly et al, 2009 ; Langhorne et al, 2009 ; Barclay et al, 2020 ). Neurofeedback (NF) is also commonly applied in the BCI system.…”

BackgroundIn combined with neurofeedback, Motor Imagery (MI) based Brain-Computer Interface (BCI) has been an effective long-term treatment therapy for motor dysfunction caused by neurological injury in the brain (e.g., post-stroke hemiplegia). However, individual neurological differences have led to variability in the single sessions of rehabilitation training. Research on the impact of short training sessions on brain functioning patterns can help evaluate and standardize the short duration of rehabilitation training. In this paper, we use the electroencephalogram (EEG) signals to explore the brain patterns’ changes after a short-term rehabilitation training.Materials and MethodsUsing an EEG-BCI system, we analyzed the changes in short-term (about 1-h) MI training data with and without visual feedback, respectively. We first examined the EEG signal’s Mu band power’s attenuation caused by Event-Related Desynchronization (ERD). Then we use the EEG’s Event-Related Potentials (ERP) features to construct brain networks and evaluate the training from multiple perspectives: small-scale based on single nodes, medium-scale based on hemispheres, and large-scale based on all-brain.ResultsResults showed no significant difference in the ERD power attenuation estimation in both groups. But the neurofeedback group’s ERP brain network parameters had substantial changes and trend properties compared to the group without feedback. The neurofeedback group’s Mu band power’s attenuation increased but not significantly (fitting line slope = 0.2, t-test value p > 0.05) after the short-term MI training, while the non-feedback group occurred an insignificant decrease (fitting line slope = −0.4, t-test value p > 0.05). In the ERP-based brain network analysis, the neurofeedback group’s network parameters were attenuated in all scales significantly (t-test value: p < 0.01); while the non-feedback group’s most network parameters didn’t change significantly (t-test value: p > 0.05).ConclusionThe MI-BCI training’s short-term effects does not show up in the ERD analysis significantly but can be detected by ERP-based network analysis significantly. Results inspire the efficient evaluation of short-term rehabilitation training and provide a useful reference for subsequent studies.

“…Acute stroke refers to a sudden cerebrovascular accident and is a medical emergency. Acute stroke can be divided into ischemic stroke and hemorrhagic stroke according to the occurrence of cerebrovascular blockage and cerebrovascular rupture, which is usually verified by imaging examination (2,3). Thrombolytic therapy, endovascular therapy, and surgery within the time window have a significant impact on the prognosis of acute stroke patients (4)(5)(6).…”

Objectives: Thousands of designated COVID-19 hospitals have been set up in China to fight the ongoing COVID-19 pandemic. Anecdotal reports indicate a falling rate of acute stroke diagnoses in these hospitals during the COVID-19 period. We conducted an exploratory single-center analysis to estimate the change in acute stroke presentation at the designated COVID-19 hospitals.Methods: This retrospective observational study included all patients admitted to Yongchuan Hospital Affiliated to Chongqing Medical University with acute stroke between January 24 and March 10, 2020. Patient demographics, characteristics of the stroke, treatment details, and clinical outcomes were compared with those of patients admitted in the corresponding period in the year before (2019, “the pre-COVID-19 period”). Subgroup analysis was performed in the ischemic and hemorrhagic stroke groups.Results: A total of 110 patients presented with acute stroke symptoms during the COVID-19 pandemic, compared with 173 patients in the pre-COVID-19 period. A higher proportion of stroke patients presented to the hospital via emergency medical services during the pandemic (48.2 vs. 31.8%, p = 0.006). There was a lower proportion of ischemic stroke patients (50.9 vs. 65.3%, p = 0.016) than in the preceding year. There were significantly fewer patients with 90-day modified Rankin Scale score ≥3 in the COVID-19 period compared with the pre-COVID-19 period (17.3 vs. 30.6%, p = 0.012). Among patients with ischemic stroke, the mean time from patient arrival to vessel puncture for emergency endovascular therapy in the COVID-19 period was shorter than that in the pre-COVID-19 period (109.18 ± 71.39 vs. 270.50 ± 161.51 min, p = 0.002). Among patients with hemorrhagic stroke, the rate of emergency surgical operation in the COVID-19 period was higher than that in the pre-COVID-19 period (48.1 vs. 30.0%, p = 0.047). The mean time from patient arrival to emergency surgical operation (15.31 ± 22.89 vs. 51.72 ± 40.47 min, p = 0.002) was shorter in the COVID-19 period than in the pre-COVID-19 period.Conclusions: Although fewer acute stroke patients sought medical care in this designated COVID-19 hospital during the COVID-19 pandemic, this type of hospital was more efficient for timely treatment of acute stroke. Recognizing how acute strokes presented in designated COVID-19 hospitals will contribute to appropriate adjustments in strategy for dealing with acute stroke during COVID-19 and future pandemics.
