Rehabilitation of post-stroke aphasia in Ghana.

BACKGROUND: Aphasia, a common consequence of stroke, which affects both communication and social functioning, and in turn, quality of life, is on the rise due to increases in stroke prevalence and survival rate. The rehabilitation of post-stroke aphasia primarily falls within the purview of speech-language pathology and research supports the effectiveness of such services. However, provision of aphasia rehabilitation services in sub-Saharan Africa is associated with challenges. AIMS: This study aimed to examine rehabilitation services for individuals with post-stroke aphasia in Ghana by exploring the roles of the stakeholder groups involved in the assessment and treatment of post-stroke aphasia in Ghana, as well as the challenges they encounter in providing or identifying services. The stakeholder groups included educational institutions, interdisciplinary healthcare professionals, and family caregivers of individuals with post-stroke aphasia. METHODS & PROCEDURES: A qualitative case study approach was used to collect and integrate from multiple sources data such as demographic information, interview responses and program syllabi to develop a holistic image. Fifteen respondents from the stroke and speech therapy units at Komfo Anokye and Korle-Bu Teaching Hospitals, University of Ghana, and University of Health and Allied Sciences, Ghana were purposively sampled. Interview questions were developed and centred on aphasia education and training, knowledge of speech-language pathology services, speech-language pathology service delivery, access to speech-language pathology services, challenges in both delivery and access to speech-language pathology services and suggestions for improving speech-language pathology services. In-person and virtual interviews were conducted after demographic information was collected. Interviews were analysed thematically, and demographic information and program syllabi were triangulated with the interview data collected. OUTCOMES & RESULTS: All stakeholder groups identified concerns with current aphasia services in Ghana. Issues raised included the insufficient number of speech-language pathologists, lack of awareness of speech-language pathology services for post-stroke aphasia (among healthcare professionals and the public), absence of aphasia management information and clinical training in educational programming, lack of interest in speech-language pathology training programs, financial challenges, spiritual and traditional beliefs and geographic barriers (i.e., speech-language pathology services are currently available in only a few cities). CONCLUSIONS & IMPLICATIONS: These findings emphasised the need to improve post-stroke aphasia rehabilitation in Ghana. The process of data collection itself educated respondents on the importance of post-stroke aphasia rehabilitation, and by identifying barriers, strategies to improving services, such as designing standardised aphasia assessments for the Ghanaian context, can now be initiated. WHAT THIS PAPER ADDS: What is already known on the subject To address post-stroke aphasia, evidence-based speech-language pathology services are provided. However, there is a paucity of studies on post-stroke aphasia services in Ghana, preventing an accurate report of services and practices in the country. What this study adds This study provides an overview of the existing rehabilitation services for post-stroke aphasia in Ghana. It highlights challenges facing the existing services and suggested strategies to improve post-stroke aphasia services. What are the clinical implications of this work? The study created awareness among healthcare professionals and general public (study participants) about the importance of rehabilitation services for post-stroke aphasia. Based on the study findings, appropriate stakeholders such as policy makers, researchers, and healthcare professionals can further design assessments and interventions to improve rehabilitation, including speech-language pathology services, for post-stroke aphasia in Ghana.

Effects of repetitive transcranial magnetic stimulation combined with music therapy in non-fluent aphasia after stroke: A randomised controlled study.

BACKGROUND: Although existing studies have shown that both repetitive transcranial magnetic stimulation (rTMS) and music therapy have advantages in the treatment of non-fluent aphasia, the efficacy of the combination of these two methods remains to be investigated. AIMS: To investigate the clinical efficacy of low-frequency rTMS combined with music therapy on language function and depression in patients with non-fluent aphasia after stroke. METHODS & PROCEDURES: A single-blind parallel randomised controlled trial was conducted. Sixty patients (mean duration = 93.78 days) with non-fluent aphasia after stroke were randomly divided into a traditional therapy group (n = 20), a music therapy group (n = 20) and a combined therapy group (n = 20, 1 Hz). The language function and depression were evaluated before and 3 weeks after treatment with the Chinese version of the Western Aphasia Battery scale, Boston Diagnostic Aphasia Examination scale and Stroke Aphasic Depression Questionnaire Hospital Version scale. OUTCOMES & RESULTS: The combined therapy group was significantly better in all outcomes than the traditional therapy group and was significantly better in depression than the music therapy group. The music therapy group was significantly better in repetition and depression than the traditional therapy group. Language improvement was positively correlated with depression improvement. For adverse events, only two patients in the combined therapy group showed slight dizziness during rTMS treatment and their symptoms improved after rest. CONCLUSIONS & IMPLICATIONS: Our preliminary randomised controlled study indicates that low-frequency rTMS combined with music therapy is feasible and safe in improving language function and depression in non-fluent aphasia patients after stroke. WHAT THIS PAPER ADDS: What is already known on this subject Repetitive transcranial magnetic stimulation (rTMS) and music therapy respectively have advantages in the treatment of non-fluent aphasia after stroke, but whether the combination of the two methods is more effective is still unknown. What this paper adds to the existing knowledge This is one of the first randomised control trials to investigate whether the clinical efficacy of low-frequency rTMS combined music therapy for non-fluent aphasia is better. The findings show that low-frequency rTMS combined music therapy is superior to traditional therapy in spontaneous speech, auditory comprehension, repetition, naming, aphasia quotient, functional language level and depression, and superior to music therapy in depression, while music therapy is superior to traditional therapy in repetition and depression. What are the potential or actual clinical implications of this work? Low-frequency rTMS combined music therapy may be a better method for treatment of non-fluent aphasia.

Current situation and trend of translational research of acupuncture-moxibustion in treatment of aphasia based on knowledge graph analysis. / åŸºäºŽçŸ¥è¯†å›¾è°±æŠ€æœ¯åˆ†æžé’ˆç¸æ²»ç–—å¤±è¯­ç—‡è½¬åŒ–ç ”ç©¶çš„çŽ°çŠ¶ä¸Žè¶‹åŠ¿.

OBJECTIVES: To investigate the hot topics in acupuncture-moxibustion research for treatment of aphasia and explore the current situation and trend of technology transformation in this field through analyzing the relevant Chinese literatures in recent 30 years by means of knowledge graph technology. METHODS: CiteSpace 6.1.R 2 and VOSviewer V1.6.16 software were used to collate the data, draw knowledge graphs and conduct visual analysis of the literatures related to acupuncture-moxibustion treatment of aphasia, searched from CNKI, WanFang and VIP databases.The time line view and strongest bursts of keywords were formed in the field of acupuncture-moxibustion treatment for aphasia. The treatment-based keyword networks were visualized. RESULTS: A total of 773 Chinese articles were included. Through visual analysis of the co-occurrence networks, the top 10 high-frequency overall keywords and the top 10 clusters of overall keywords were listed. The top 5 high-frequency aphasia categories were Broca aphasia, hysterical aphasia, transcortical motor aphasia, nominal aphasia and sensory aphasia. Regarding the keywords of the techniques of acupuncture-moxibustion, the occurrence frequencies of scalp acupuncture, tongue acupuncture, body acupuncture and electroacupuncture were ≥ 10 times.The occurrence frequencies of 16 acupoints were ≥25 times. After collation and cluster analysis of acupoints and techniques of acupuncture-moxibustion, 7 keyword clusters of "acupuncture techniques-acupoints" were obtained. The time line view showed that the strongest burst of keywords were transcranial magnatic stimulation, language rehabilitation training, acupuncture-medicine therapy and stroke, etc. in the recent 5 years. CONCLUSIONS: Acupuncture-moxibustion displays its unique advantage in treatment of aphasia. With the deepening of modern research, the hot topics for aphasia treated with acupuncture-moxibustion are present and the achievements enriched. In future, these therapeutic methods should be further investigated to explore a model of translational medicine for aphasia in line with the characteristics of acupuncture-moxibustion.

Methodologies for task-fMRI based prognostic biomarkers in response to aphasia treatment.

With the diversity in aphasia coupled with diminished gains at the chronic phase, it is imperative to deliver effective rehabilitation plans. Treatment outcomes have therefore been predicted using lesion-to-symptom mapping, but this method lacks holistic functional information about the language-network. This study, therefore, aims to develop whole-brain task-fMRI multivariate analysis to neurobiologically inspect lesion impacts on the language-network and predict behavioral outcomes in persons with aphasia (PWA) undergoing language therapy. In 14 chronic PWA, semantic fluency task-fMRI and behavioral measures were collected to develop prediction methodologies for post-treatment outcomes. Then, a recently developed imaging-based multivariate method to predict behavior (i.e., LESYMAP) was optimized to intake whole-brain task-fMRI data, and systematically tested for reliability with mass univariate methods. We also accounted for lesion size in both methods. Results showed that both mass univariate and multivariate methods identified unique biomarkers for semantic fluency improvements from baseline to 2-weeks post-treatment. Additionally, both methods demonstrated reliable spatial overlap in task-specific areas including the right middle frontal gyrus when identifying biomarkers of language discourse. Thus whole-brain task-fMRI multivariate analysis has the potential to identify functionally meaningful prognostic biomarkers even for relatively small sample sizes. In sum, our task-fMRI based multivariate approach holistically estimates post-treatment response for both word and sentence production and may serve as a complementary tool to mass univariate analysis in developing brain-behavior relationships for improved personalization of aphasia rehabilitation regimens.

[The institutional presence of music therapists in aphasia therapy in Hungary]. / Zeneterapeuták intézményi jelenléte a magyarországi aphasiaterápiában.

INTRODUCTION: Numerous international studies have reported on the relevance of music therapy for aphasia, but music-based therapy for the rehabilitation of acquired language and speech disorders is not common in the clinical practice of Hungary. OBJECTIVE: The aim of our study is to provide insights into the composition of professional teams involved in aphasia care in active neurology and stroke wards and rehabilitation departments in Hungarian hospitals, with a special focus on the presence of music therapists. We are looking for the answer to why the employment of music therapists in hospitals is so low in our country. METHOD: For our research, we selected the relevant institutions and departments from a list of hospitals on the website of the National Directorate General for Hospitals. Data were then collected from the websites of the hospital departments, supplemented or clarified with information from the head of department's physicians where necessary. RESULTS: None of the active neurology and stroke wards employ a music therapist. Two of the rehabilitation wards have a total of 4 music therapists. DISCUSSION: The low number of trained professionals in music therapy for aphasia is due to financial reasons, lack of professionals and lack of professional demand. CONCLUSION: Our research shows that music therapy is deeply underrepresented in the field of aphasia rehabilitation in Hungarian hospitals. The reasons for this are quite diverse and their elimination would require effective intervention in many areas. Orv Hetil. 2023; 164(19): 747-752.

[The rules of acupoint selection of acupuncture and moxibustion for aphasia based on data mining].

OBJECTIVE: To explore the rules of acupoint selection for aphasia treated with acupuncture and moxibustion using data mining technology. METHODS: From January 1, 2000 to April 1, 2022, the articles for clinical researches of acupuncture and moxibustion for aphasia published in CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase were searched. Using Microsoft Excel 2021, the database was set up to analyze the use frequency of acupoint, meridian tropism, acupoint distribution and the use of specific points. SPSS26.0 was adopted for factor analysis, SPSS Modeler 18.0 was for association rule analysis of prescriptions, and Gephi 0.9.5 was to plot the co-occurrence network diagrams of acupoints and meridians. RESULTS: A total of 140 articles were collated, including 146 acupuncture and moxibustion prescriptions and 189 acupoints. The total use frequency of these acupoints was 1 211. Lianquan (CV 23), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20) and Yamen (GV 15) were the top 5 acupoints of the high use frequency for aphasia treated with acupuncture and moxibustion. Among 189 acupoints collected, the extra points and empirical points were mostly selected. The top 3 involved meridians were the governor vessel, the gallbladder meridian of foot-shaoyang and the conception vessel. These acupoints were mostly distributed on the head, face and neck region. The use frequency of five-shu points was the highest among the specific points. The acupoint combinations of high frequency referred to Yuye (EX-HN 13)-Jinjin (EX-HN 12), Yuye (EX-HN 13)-Lianquan (CV 23)-Jinjin (EX-HN 12), and Fengchi (GB 20)-Yuye (EX-HN 13)-Jinjin (EX-HN 12). Factor analysis extracted 10 common factors for acupoint compatibility in treatment of aphasia with acupuncture and moxibustion. CONCLUSION: In clinical treatment of aphasia with acupuncture and moxibustion, the local acupoints are preferred. The core acupoints include Lianquan (CV 23), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20) and Yamen (GV 15). The acupoint prescription is modified flexibly according to syndrome differentiation to enhance the therapeutic effect.

Music Therapy in Global Aphasia: A Case Report.

Patients affected by global aphasia are no longer able to understand, produce, name objects, write and read. It occurs as a result of functional damage of ischemic or hemorrhagic origin affecting the entire peri-silvan region and frontal operculum. Rehabilitation training aims to promote an early intervention in the acute phase. We described a case of a 57-year-old female patient with left intraparenchymal fronto-temporo-parietal cerebral hemorrhage and right hemiplegia. After admission to clinical rehabilitative center, the patient was not able to perform simple orders and she presented a severe impairment of auditory and written comprehension. Eloquence was characterized by stereotypical emission of monosyllabic sounds and showed compromised praxis-constructive abilities. Rehabilitation included a program of Neurologic Music Therapy (NMT), specifically Symbolic Communication Training Through Music (SYCOM) and Musical Speech Stimulation (MUSTIM). Rehabilitative treatment was measured by improved cognitive and language performance of the patient from T0 to T1. Music rehabilitative interventions and continuous speech therapy improve visual attention and communicative intentionality. In order to confirm the effectiveness of data presented, further extensive studies of the sample would be necessary, to assess the real role of music therapy in post-stroke global aphasia.

Speech therapy and hyperbaric oxygen for aphasia after carbon monoxide intoxication.

Acute carbon monoxide (CO) intoxication may result in delayed neurological sequelae, which can include amnesia, ataxia, aphasia, emotional lability, disorientation, dysphagia, and other manifestations. A 27-year-old man reported symptoms of aphasia with agraphia and alexia in a review after CO intoxication. The patient received outpatient speech therapy, as well as repeated sessions of hyperbaric oxygen for 15 days, interspersing speech therapy with hyperbaric oxygen therapy for two months. After this period of combined treatment the aphasic symptomatology remitted, and oral and written language was normal. The complete disappearance of aphasia with agraphia and alexia confirms the efficacy of the combined intervention. More data from large clinical studies are needed to assess the outcomes of hyperbaric oxygen treatment in patients with delayed neurological sequelae after CO intoxication, but this case suggests it may be a good therapeutic option in combination with specific speech therapy.

[Kaiqiao Jieyin acupuncture combined with repetitive transcranial magnetic stimulation for post-stroke aphasia: a randomized controlled trial].

OBJECTIVE: To observe the effect of Kaiqiao Jieyin acupuncture (acupuncture for opening orifices and relieving aphasia) combined with repetitive transcranial magnetic stimulation (rTMS) on language ability and daily life communication ability in patients with post-stroke aphasia (PSA). METHODS: Fifty-six patients with PSA were randomly divided into an observation group and a control group, 28 cases in each group. Both groups received routine symptomatic treatment. The control group was treated with speech rehabilitation training and rTMS. On the basis of the treatment in the control group, the observation group was treated with Kaiqiao Jieyin acupuncture at the speech area Ⅰ, Fengchi (GB 20), Tongli (HT 5), Lianquan (CV 23), Panglianquan (Extra), etc. Panglianquan (Extra) on both sides were connected to electroacupuncture, with intermittent wave, 2 Hz in frequency. The above treatment was performed once a day for 5 consecutive days, followed by 2 days of rest for 2 weeks. The scores of western aphasia battery (WAB, including scores of spontaneous speech, auditory comprehension, repetition, naming and score of aphasia quotient [AQ]) and communication abilities in daily living (CADL) in the two groups were compared before and after treatment. RESULTS: After treatment, the spontaneous speech, auditory comprehension, repetition, naming scores and AQ scores in both groups were higher than those before treatment (P<0.05), and the increase in the observation group was greater than the control group (P<0.05). The CADL scores of the two groups were higher than those before treatment (P<0.05). CONCLUSION: Kaiqiao Jieyin acupuncture combined with rTMS can improve the language ability and daily life communication ability of PSA patients.

"There are endless areas that they can use it for": speech-language pathologist perspectives of technology support for aphasia self-management.

BACKGROUND: Aphasia is a debilitating acquired language disorder that often persists as a chronic condition. However, long-term support options are scarce, necessitating the consideration of alternative approaches. Chronic condition self-management approaches, which aim to build self-efficacy and empower people to take responsibility for the day-to-day management of their health condition, may benefit people with aphasia (PwA). Technology is widely used in chronic condition self-management and investigation is required to determine whether it could play a role in aphasia self-management. OBJECTIVE: This study aimed to explore speech-language pathologist (SLP) perspectives on the potential use of technology to support aphasia self-management. METHODS: A qualitative study was conducted with 15 SLPs using semi-structured interviews. Qualitative content analysis was applied to verbatim transcripts to identify codes, categories, and sub-themes which were developed into themes. RESULTS: Three themes were identified: (1) technology supports holistic aphasia self-management by providing additional avenues for service delivery, overall communication, and learning opportunities thus enhancing independence and life participation; (2) SLP and communication partner (CP) assistance can support PwA to use technology for aphasia self-management; (3) considerations and potential barriers to PwA use of technology for aphasia self-management. CONCLUSIONS: Technology can support aphasia self-management by expanding service delivery options, allowing for increased frequency and intensity of therapy practise, and facilitating communication and participation. Personal, professional, and organizational barriers should be addressed in the development of technology-enabled aphasia self-management approaches. SLPs and CPs can offer PwA assistance with technology but may themselves need additional support. Solutions for identified barriers should be considered, such as providing training in the use of technology and implementing aphasia-friendly modifications.IMPLICATIONS FOR REHABILITATIONSelf-management approaches are being explored in the area of aphasia management as a means of offering a holistic, sustainable intervention option that meets the long-term needs of people with aphasia.A range of technology-based resources are currently used in chronic condition self-management and in aphasia therapy, and there are many possibilities for the use of technology in aphasia self-management approaches.Speech-language pathologists identified that technology could facilitate aphasia self-management by expanding service delivery options (e.g., real-time and asynchronous telepractice), enabling increased frequency and intensity of therapy through providing a means of independent practise, offering options for augmentative alternative communication, and enhancing life participation by supporting social communication and daily tasks.,Speech-language pathologists are interested in using technology for aphasia self-management; however, barriers related to organizational policies, individual experience and confidence using technology, and technology itself must be addressed.

Design and practice of a production-oriented teaching model in a traditional Chinese medicine culture ESP course / 中华医学教育探索杂志

The phenomenon of "Chinese cultural aphasia" in college English education in China is typically represented by "traditional Chinese medicine (TCM) cultural aphasia" in English learning among students in TCM colleges and universities, which is mainly caused by insufficient driving force for input and production in both teaching and learning. Based on the production-oriented approach, this study designs a teaching model oriented by "TCM culture" production in the ESP course of Introducing TCM Culture in English and conducts a practice research according to the teaching process of driving, facilitating, and evaluating. The practice research shows that the application of this model has effectively integrated "national sentiment" and "national consciousness" into the teaching and learning of the TCM ESP course, improved the TCM culture production ability among students, realized the educational effect of foreign language teaching, and promoted the teaching and research practice of teachers.

Analysis of changes in connectivity of resting brain functional network before and after acupuncture combined with language rehabilitation training in patients with basal ganglia aphasia after stroke / 中国医师杂志

Objective:To use the resting state functional network connectivity (FNC) method based on independent component analysis (ICA) to analyze the characteristics of FNC changes in patients with basal ganglia aphasia (BGA) after stroke, and to explore its occurrence and recovery mechanism under the intervention of acupuncture combined with language rehabilitation training.Methods:Using a prospective observational research method, 16 right-handed BGA patients who were treated at Beijing Hospital of Traditional Chinese Medicine, Capital Medical University from July 2021 to December 2022, as well as 14 healthy subjects matched in age, gender, education level, and handedness, were included. The resting state functional magnetic resonance imaging, demographic information, and Western Aphasia Examination data of healthy subjects and BGA patients before and after intervention were collected. The GIFT toolbox based on MATLAB platform was applied for ICA and resting state brain network FNC analysis. The FNC differences between BGA patients and healthy subjects were compared horizontally, and the FNC changes in BGA patients before and after intervention were compared vertically.Results:Compared with healthy subjects, post-stroke BGA patients showed decreased connectivity between the basal ganglia network, default network, and visual network before intervention, while increased connectivity between the auditory network, right frontoparietal network, and anterior cuneiform network; After the intervention of acupuncture combined with language rehabilitation training, the connectivity between the basal ganglia network, visual network, and anterior cuneiform network decreased, while the connectivity between the anterior convex network and bilateral frontoparietal network decreased, while the connectivity between the default network, auditory network, right frontoparietal network, and visual network increased. The BGA patient group showed enhanced connectivity between the basal ganglia network and the left frontoparietal network before and after intervention.Conclusions:The FNC changes between the basal ganglia network and other brain networks are key to reflecting the mechanism of BGA occurrence and language function recovery. Acupuncture combined with language rehabilitation training may improve language function by enhancing the connectivity between the basal ganglia network and the left frontoparietal network, and the redistribution of attention resources may also be one of the reasons for promoting language function recovery in BGA patients.

Modulations of static and dynamic functional connectivity among brain networks by electroacupuncture in post-stroke aphasia.

Introduction: Post-stroke aphasia (PSA) is a language disorder caused by left hemisphere stroke. Electroacupuncture (EA) is a minimally invasive therapeutic option for PSA treatment. Tongli (HT5) and Xuanzhong (GB39), two important language-associated acupoints, are frequently used in the rehabilitation of patients with PSA. Preliminary evidence indicated functional activation in distributed cortical areas upon HT5 and GB39 stimulation. However, research on the modulation of dynamic and static functional connectivity (FC) in the brain by EA in PSA is lacking. Method: This study aimed to investigate the PSA-related effects of EA stimulation at HT5 and GB39 on neural processing. Thirty-five participants were recruited, including 19 patients with PSA and 16 healthy controls (HCs). The BOLD signal was analyzed by static independent component analysis, generalized psychophysiological interactions, and dynamic independent component analysis, considering variables such as age, sex, and years of education. Results: The results revealed that PSA showed activated clusters in the left putamen, left postcentral gyrus (PostCG), and left angular gyrus in the salience network (SN) compared to the HC group. The interaction effect on temporal properties of networks showed higher variability of SN (F = 2.23, positive false discovery rate [pFDR] = 0.017). The interaction effect on static FC showed increased functional coupling between the right calcarine and right lingual gyrus (F = 3.16, pFDR = 0.043). For the dynamic FC, at the region level, the interaction effect showed lower variability and higher frequencies of circuit 3, with the strongest connections between the supramarginal gyrus and posterior cingulum (F = 5.42, pFDR = 0.03), middle cingulum and PostCG (F = 5.27, pFDR = 0.036), and triangle inferior frontal and lingual gyrus (F = 5.57, pFDR = 0.026). At the network level, the interaction effect showed higher variability in occipital network-language network (LN) and cerebellar network (CN) coupling, with stronger connections between the LN and CN (F = 4.29, pFDR = 0.042). Dynamic FC values between the triangle inferior frontal and lingual gyri were anticorrelated with transcribing, describing, and dictating scores in the Chinese Rehabilitation Research Center for Chinese Standard Aphasia Examination. Discussion: These findings suggest that EA stimulation may improve language function, as it significantly modulated the nodes of regions/networks involved in the LN, SN, CN, occipital cortex, somatosensory regions, and cerebral limbic system.

Thalamic Aphasia: a Review.

PURPOSE OF REVIEW: Thalamic aphasia is a rare language disorder resulting from lesions to the thalamus. While most patients exhibit mild symptoms with a predominance of lexical-semantic difficulties, variations in phenotype have been described. Overall, the exact mechanisms of thalamic aphasia await empirical research. The article reviews recent findings regarding phenotypes and possible underlying mechanisms of thalamic aphasia. RECENT FINDINGS: Variations in phenotype of thalamic aphasia may be related to different lesion locations. Overall, the thalamus' role in language is thought to be due to its involvement in cortico-thalamic language networks with lesioning of certain nuclei resulting in the diachisis of otherwise interconnected areas. Its possible monitoring function in such a network might be due to its different cellular firing modes. However, no specific evidence has been collected to date. While recent findings show a more distinct understanding of thalamic aphasia phenotypes and possible underlying mechanisms, further research is needed. Additionally, as standard language testing might oftentimes not pick up on its subtle symptoms, thalamic aphasia might be underdiagnosed.

Effects of Acupuncture-Related Therapies in the Rehabilitation of Patients with Post-Stroke Aphasia-A Network Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: The purpose of this study was to evaluate the rehabilitation effects of four common interventions (BA: body acupuncture, SA: scalp acupuncture, TA: tongue acupuncture, SLT: speech and language training) used singly or in combination with language function in patients with post-stroke aphasia (PSA). DESIGN: We systematically searched PubMed, EMBASE, Cochrane Library, Ovid, Web of Science, CNKI, VIP, and Wanfang from inception to 4 April 2022. Only randomized controlled trials that met the eligibility criteria were included. The risk of bias of studies included was assessed using the RoB-2 tool. The effects of different interventions for PSA patients were analyzed and ranked according to the surface under the cumulative ranking (SUCRA) analysis. RESULTS: A total of 69 RCTs were included, including 5097 total participants. According to the results of the SUCRA curves, TA ranked highest in improving overall efficacy (SUCRA = 86%) and oral expression score (SUCRA = 86%). BA + TA ranked highest in increasing the comprehension score (SUCRA = 74.9%). BA + SA ranked highest in improving aphasia patients' repetition (SUCRA = 89.2%) and denomination scores (SUCRA = 93%). CONCLUSIONS: Results of our network meta-analysis and SUCRA ranking showed that tongue acupuncture, body acupuncture + tongue acupuncture, and body acupuncture + scalp acupuncture seem to offer better advantages than other interventions for improving the language function in PSA patients. Moreover, it is noteworthy that our results are limited to the Chinese population, since all eligible studies are from China. Future well-designed studies with larger sample sizes and more ethnic groups are required to further verify these findings.

Mindfulness and Relaxation Techniques for Stroke Survivors with Aphasia: A Feasibility and Acceptability Study.

Stroke survivors with aphasia (SsWA) tend to experience high levels of anxiety and stress, leading to an increased risk of recurrent strokes. Mindfulness and/or relaxation that does not require language outputs could reduce psychosocial stress; however, these approaches work best if they consist of a range of techniques and are modified to suit the needs of SsWA. Using a mixed-methods approach, we examined the feasibility and acceptability of a set of tailored mindfulness and relaxation techniques for SsWA. Nine SsWA were recruited (six men and three women, median age = 51 years). Four relaxation and mindfulness techniques which had been tailored for SsWA were filmed into a DVD/YouTube video and were given to participants together with a practice diary for home practice once daily for 5 weeks. The participants joined focus group discussions and completed a feasibility scale 5 weeks later. The participants perceived these techniques as easy, user-friendly and acceptable for SsWA in general. Although practised less often than instructed, many participants reported benefits of regular practice. The perceived relevance of these techniques to the participants' own situations and the intention to continue varied. Future research could encourage the regular practice of self-help interventions by incorporating behavioural change techniques such as using prompts and cues.
