NeuroRehabilitation 2024Non-invasive brain stimulation has been widely used as an adjunctive treatment for aphasia following stroke. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Non-invasive brain stimulation has been widely used as an adjunctive treatment for aphasia following stroke.
OBJECTIVE
The aim of this study was to investigate the effect of non-invasive brain stimulation as an adjunctive treatment on naming function in aphasia following stroke.
METHODS
This review included randomized controlled trials (RCTs) involving 5 databases (Web of Science, Embase, Cochrane Library, OVID and PubMed) that investigated the effects of electrical stimulation on stroke patients. The search included literature published up to November 2023.
RESULTS
We identified 18 studies, and the standardized mean differences (SMDs) showed that the effect sizes of TMS and tDCS were small to medium. Moreover, the treatment effects persisted over time, indicating long-term efficacy.
CONCLUSION
This study suggested that NIBS combined with speech and language therapy can effectively promote the recovery of naming function in patients with post-stroke aphasia (PSA) and that the effects are long lasting.

OBJECTIVE
To examine the proportion of people with aphasia (PwA) included and retained in randomised controlled trials (RCTs) of stroke interventions published in the previous 6 years, as well as aphasia-relevant eligibility criteria and inclusion/retention strategies.
DATA SOURCES
Comprehensive searching of Embase, PubMed and Medline (Ovid) for the period January 2016 - November 2022.
REVIEW METHODS
RCTs examining stroke interventions targeting cognition, psychological wellbeing/health-related quality of life (HRQL), multidisciplinary rehabilitation, and self-management were included. Methodological quality was assessed using the Critical Appraisal Skills Programme (CASP) Randomised Controlled Trial checklist. Descriptive statistics were applied to extracted data, and results were reported narratively.
RESULTS
Fifty-seven RCTs were included. These examined self-management (32%), physical (26%) psychological wellbeing/HRQL (18%), cognitive (14%), and multidisciplinary (11%) interventions. Of 7313 participants, 107 (1.5%) had aphasia and were included in three trials. About one-third did not report on aphasia (32%); over one quarter required functional communication (28%); one quarter excluded all aphasia (25%); and 14% excluded severe aphasia. No aphasia-specific inclusion/retention strategies were available.
CONCLUSION
The findings highlight ongoing under-representation. However, due to shortcomings in aphasia reporting, the findings may underestimate actual inclusion rate. Excluding PwA has implications for the external validity, effectiveness, and implementation of stroke research findings. Triallists may require support in aphasia research strategies and methodological reporting.

Various post-stroke dysfunctions often result in poor long-term outcomes for stroke survivors, but the effect of conventional treatments is limited. In recent years, lots of studies have confirmed the effect of repetitive transcranial magnetic stimulation (rTMS) in stroke rehabilitation. As a new pattern of rTMS, theta burst stimulation (TBS) was proved recently to yield more pronounced and long-lasting after-effects than the conventional pattern at a shorter stimulation duration. To explore the role of TBS in stroke rehabilitation, this review summarizes the existing evidence from all the randomized controlled trials (RCTs) so far on the efficacy of TBS applied to different post-stroke dysfunctions, including cognitive impairment, visuospatial neglect, aphasia, dysphagia, spasticity, and motor dysfunction. Overall, TBS promotes the progress of stroke rehabilitation and may serve as a preferable alternative to traditional rTMS. However, it's hard to recommend a specific paradigm of TBS due to the limited number of current studies and their heterogeneity. Further high-quality clinical RCTs are needed to determine the optimal technical settings and intervention time in stroke survivors.

BACKGROUND
Stroke presentation secondary to a cardiac myxoma thromboembolism is rare in the pediatric population. Because of such rarity, the reported cases in the literature are primarily case reports. Additionally, general pediatric stroke management lacks evidence-based guidelines because of its low incidence and lack of clinical trials. In pediatric strokes identified from a cardiac myxoma, the incidence favors boys with the classical presentation of unilateral weakness and aphasia. We present a pediatric patient who presented with strokelike symptoms secondary to an intracranial embolus from a previously undiagnosed cardiac myxoma.
METHODS
We performed a systematic review by searching PubMed, Google Scholar, Web of Science, and Embase databases for cases of pediatric myxoma causing stroke (n = 2431) and identified 19 reported uses of surgical management in treating pediatric patients who present with stroke symptoms secondary to a cardiac myxoma thromboembolism.
RESULTS
The most common imaging modality was magnetic resonance imaging in 42% of cases, computed tomography in 36.8%, followed by computed tomography angiography in 31.6% of cases. Of these 19 children treated with procedures, 36.8% of pediatric patients aged between 4 and 14 years underwent neurosurgery (n = 7).
CONCLUSIONS
We describe an urgent mechanical thrombectomy and share preoperative and postoperative images and pathology slides confirming a stroke from myxoma origin. We provide added insight in the safe use of mechanical thrombectomy as treatment for pediatric strokes secondary to a thromboembolism.

Meta-Analysis
PURPOSE
This investigation sought to systematically assess music therapy's impact on aphasia and cognition in patients with post-stroke.
METHODS
Comprehensive searches were performed across major databases, including PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, and Vip Chinese sci-tech periodicals (VIP), covering publications up to December 2023. After screening and extracting data from the retrieved literature, its quality was appraised, which was followed by a meta-analysis using RevMan software (version 5.4, Cochrane Collaboration, Oxford, UK).
RESULTS
Nine articles, which were published from 2008 to 2022, were covered in this investigation, comprising 309 stroke patients in total. Meta-analysis results from these variations were found to be not statistically significant in the degree of functional communication improvement between the experimental group and the control group (standardized mean difference [SMD] = 0.23, 95% confidence interval [CI] (-0.19; 0.77), P > 0.05). These variations were found to be not statistically significant in the improvement of understanding ability in the experimental group compared with that in the control group (SMD = 0.21, 95% CI [-0.66; 1.09], P > 0.05). The degree of improvement in repetitive ability of the experimental group was considerably greater than that of the control group (SMD = 0.37, 95% CI [0.01; 0.76], P < 0.05). These variations were found to be not statistically significant in the improvement of naming ability in the experimental group compared with that in the control group (SMD = 0.30, 95% CI [-0.19; 0.80], P > 0.05). The cognitive score of the experimental group was considerably greater than that of the control group (SMD = 0.75, 95% CI [0.44; 1.06], P < 0.05).
CONCLUSION
Music therapy can effectively ameliorate the repetition ability of patients with aphasia after stroke. It can also improve the cognitive ability of patients. Thus, music therapy could be further applied to treat this type of patients.

BACKGROUND
Although people with aphasia (PwA) represent 30% of stroke survivors, they are frequently excluded from stroke research, or their inclusion is unclear. Such practice significantly limits the generalizability of stroke research, increases the need to duplicate research in aphasia-specific populations, and raises important ethical and human rights issues.
OBJECTIVE
To detail the extent and nature of inclusion of PwA in contemporary stroke randomized controlled trials (RCTs).
METHODS
We conducted a systematic search to identify completed stroke RCTs and RCT protocols published in 2019. Web of Science was searched using terms "stroke" and "randomized controlled trial". These articles were reviewed by extracting rates of PwA inclusion/exclusion, whether "aphasia" or related terms were referred to in the article or supplemental files, eligibility criteria, consent procedures, adaptations made to support the inclusion of PwA, and attrition rates of PwA. Data were summarized, and descriptive statistics applied when appropriate.
RESULTS
271 studies comprising 215 completed RCTs and 56 protocols were included. 36.2% of included studies referred to aphasia/dysphasia. Of completed RCTs, only 6.5% explicitly included PwA, 4.7% explicitly excluded PwA, and inclusion was unclear in the remaining 88.8%. Among RCT protocols, 28.6% of studies intended inclusion, 10.7% intended excluding PwA, and in 60.7%, inclusion was unclear. In 45.8% of included studies, sub-groups of PwA were excluded, either explicitly (ie, particular types/severities of aphasia, eg, global aphasia) or implicitly, by way of ambiguous eligibility criteria which could potentially relate to a sub-group of PwA. Little rationale for exclusion was provided. 71.2% of completed RCTs did not report any adaptations that could support the inclusion of PwA, and minimal information was provided about consent procedures. Where it could be determined, attrition of PwA averaged 10% (range 0%-20%).
CONCLUSION
This paper details the extent of inclusion of PwA in stroke research and highlights opportunities for improvement.

Review
OBJECTIVE
This study aimed to determine whether targeting specific implementation determinants is associated with allied health clinicians' uptake of evidence when implemented within stroke rehabilitation settings.
DATA SOURCES
7 key databases were searched to identify articles published between 1990 and 2022 for inclusion. Reference lists of relevant articles were hand searched.
STUDY SELECTION
Studies were independently screened by 2 authors and included if the implementation intervention targeted allied health clinical practice in any stroke rehabilitation context and reported at least 1 quantitative measure of evidence uptake. Thirty studies met inclusion criteria.
DATA EXTRACTION
Data were independently extracted by the first and second author. Implementation outcomes for each study were categorized as either mostly successful, partially successful, or not successful based on the degree of evidence uptake achieved. Determinants targeted were categorized using the Consolidated Framework for Implementation Research (CFIR).
DATA SYNTHESIS
Patterns between the degree of evidence uptake and determinants targeted across studies were analyzed by the first and second authors in 1 of 3 groups: A (pre-post statistical analysis), B (pre-post descriptive analysis), or C (post-only descriptive analysis). Patterns between evidence uptake and determinants targeted were first identified within groups A and B, with group C consulted to support findings. All studies categorized as "mostly successful" targeted facilitation in combination with establishing face-to-face networks and communication strategies. Conversely, no studies rated "not successful" targeted either of these determinants. Studies rated "partially successful" targeted either 1, but seldom both, of these determinants.
CONCLUSIONS
This review has provided descriptive evidence of determinants which may be important to target for allied health clinicians' uptake of evidence within stroke rehabilitation settings.

Review
BACKGROUND
Primary progressive aphasia (PPA) accounts for approximately 43% of frontotemporal dementias and is mainly characterised by a progressive impairment of speech and communication abilities. Three clinical variants have been identified: (a) non-fluent/agrammatic, (b) semantic, and (c) logopenic/phonological PPA variants. There is currently no curative treatment for PPA, and the disease progresses inexorably over time, with devastating effects on speech and communication ability, functional status, and quality of life. Several non-pharmacological interventions that may improve symptoms (e.g. different forms of language training and non-invasive brain stimulation) have been investigated in people with PPA.
OBJECTIVES
To assess the effects of non-pharmacological interventions for people with PPA on word retrieval (our primary outcome), global language functions, cognition, quality of life, and adverse events.
SEARCH METHODS
We searched the Cochrane Dementia and Cognitive Improvement Group's trial register, MEDLINE (Ovid SP), Embase (Ovid SP), four other databases and two other trial registers. The latest searches were run on 26 January 2024.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) evaluating the effects of non-pharmacological interventions in people with PPA.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
There were insufficient data available to conduct the network meta-analyses that we had originally planned (due to trial data being insufficiently reported or not reported at all, as well as the heterogeneous content of the included interventions). Therefore, we provide a descriptive summary of the included studies and results. We included 10 studies, with a total of 132 participants, evaluating non-pharmacological interventions. These were: transcranial direct current stimulation (tDCS) or repetitive transcranial magnetic stimulation (rTMS) as stand-alone treatments (used by two and one studies, respectively); tDCS combined with semantic and phonological word-retrieval training (five studies); tDCS combined with semantic word-retrieval training (one study); and tDCS combined with phonological word-retrieval training (one study). Results for our primary outcome of word retrieval were mixed. For the two studies that investigated the effects of tDCS as stand-alone treatment compared to placebo ("sham") tDCS, we rated the results as having very low-certainty evidence. One study found a significant beneficial effect on word retrieval after active tDCS; one study did not report any significant effects in favour of the active tDCS group. Five studies investigated tDCS administered to the dorsolateral prefrontal cortex, inferior frontal cortex, left frontotemporal region, or the temporoparietal cortex, combined with semantic and phonological word-retrieval training. The most consistent finding was enhancement of word-retrieval ability for trained items immediately after the intervention, when behavioural training was combined with active tDCS compared to behavioural training plus sham tDCS. We found mixed effects for untrained items and maintenance of treatment effects during follow-up assessments. We rated the certainty of the evidence as very low in all studies. One study investigated tDCS combined with semantic word-retrieval training. Training was provided across 15 sessions with a frequency of three to five sessions per week, depending on the personal preferences of the participants. tDCS targeted the left frontotemporal region. The study included three participants: two received 1 mA stimulation and one received 2 mA stimulation. The study showed mixed results. We rated it as very low-certainty evidence. One study investigated tDCS combined with phonological word-retrieval training. Training was again provided across 15 sessions over a period of three weeks. tDCS targeted the left inferior frontal gyrus. This study showed a significantly more pronounced improvement for trained and untrained words in favour of the group that had received active tDCS, but we rated the certainty of the evidence as very low. One study compared active rTMS applied to an individually determined target site to active rTMS applied to a control site (vertex) for effects on participants' word retrieval. This study demonstrated better word retrieval for active rTMS administered to individually determined target brain regions than in the control intervention, but we rated the results as having a very low certainty of evidence. Four studies assessed overall language ability, three studies assessed cognition, five studies assessed potential adverse effects of brain stimulation, and one study investigated quality of life.
AUTHORS' CONCLUSIONS
There is currently no high-certainty evidence to inform clinical decision-making regarding non-pharmacological treatment selection for people with PPA. Preliminary evidence suggests that the combination of active tDCS with specific language therapy may improve impaired word retrieval for specifically trained items beyond the effects of behavioural treatment alone. However, more research is needed, including high-quality RCTs with detailed descriptions of participants and methods, and consideration of outcomes such as quality of life, depressive symptoms, and overall cognitive functioning. Moreover, studies assessing optimal treatments (i.e. behavioural interventions, brain stimulation interventions, and their combinations) for individual patients and PPA subtypes are needed. We were not able to conduct the planned (network) meta-analyses due to missing data that could not be obtained from most of the authors, a general lack of RCTs in the field, and heterogeneous interventions in eligible trials. Journals should implement a mandatory data-sharing requirement to assure transparency and accessibility of data from clinical trials.

BACKGROUND
Stroke is a cerebrovascular disease with high prevalence and mortality, and upper limb hemiparesis is a major factor limiting functional recovery in stroke patients. Improvement of motor function in stroke patients through various forms of constraint-induced movement therapy (CITM) has been recognized as safe and effective in recent years. This research field lacks a comprehensive systematic and clear vein combing analysis, analyzing the literature research of CIMT in the field of rehabilitation in the past three decades, summarizing the research hotspots and cutting-edge trends in this field, in an effort to offer ideas and references for subsequent researchers.
METHODS
Relevant literature on CIMT in rehabilitation was collected from 1996 to 2024 within the Web of Science database's core dataset by using CiteSpace6.1, VOSviewer1.6.18, R-bibliometrix4.6.1, Pajek5.16, Scimago Graphica 1.0.26 software for visualization and analysis.
RESULTS
There were 970 papers in all United States was ranked first with 401 papers. Alabama Univ was ranked first for institutions with 53 papers. Neurorehabilitation and Neural Repair was ranked first for journals with 78 papers, and Taub E was ranked first for author publications with 64 papers. Research keywords were CIMT, stroke rehabilitation, upper extremity function, lower extremity gait balance, randomized controlled trials, physical therapy techniques (transcranial magnetic stimulation and sensory amplitude electrical stimulation), primary motor cortex plasticity, lateral dominance (spatial behaviors), cerebral vascular accidents, activities of daily living, hand function, disability, functional restoration, bimanual training, aphasia, acquired invalidity, type A Botulinum toxin and joystick riding toys.
CONCLUSION
The current state of research shows that CIMT still has a vast potential for development in the field of rehabilitation research. The research hotspots are the clinical efficacy of CIMT combined with other therapies (botulinum toxin type A, transcranial direct current stimulation, virtual reality, mirror therapy, robotic-assisted) to enhance the functionality of upper limb hemiparesis in stroke patients, the mechanism of CIMT to improve the plasticity of the motor cortex through electrophysiological and imaging methods, and improvement of lower limb gait balance function in stroke patients and aphasia applications, the optimal intervention time and dose, and exploration of CIMT in new settings such as robot-assisted, telemedicine, and home rehabilitation.

Chronic pain is prevalent after stroke and has a significant impact on quality of life. Research demonstrates the efficacy of psychological interventions for mixed chronic pain conditions. This review aimed to assess evidence on the effectiveness of psychological interventions for chronic pain in people with stroke. PubMed, PsychINFO, Embase, and CINAHL were searched from inception to 31 January 2021 at all levels of evidence. Psychological interventions assessing chronic pain in adults following stroke as a primary outcome were included. All outcomes related to pain quality were included (e.g., intensity, frequency, duration). Study quality was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Case Reports and Risk of Bias in N-of-1 Trials (RoBiNT) Scale. Three single case reports were included. A narrative synthesis was performed, indicating that psychological interventions may reduce chronic post-stroke pain; however, overall quality appraisal of the included studies was poor, owing to the low internal validity found in the single- case report designs. The limited evidence suggests that psychological interventions may have clinical utility in reducing chronic post-stroke pain. However, owing to the paucity and quality of studies found, the results must be treated with caution. More rigorous research is needed.
