    Objective. The purpose of this study was to examine the evidence regarding the efficacy of rehabilitation approaches for improving severe upper limb impairments and activity during acute and early subacute stroke, taking into consideration the dosage of therapy. Methods. Randomized controlled trials from PubMed, Web of Science, and Scopus databases were searched by 2 independent researchers. Studies were selected if they involved active rehabilitation interventions that were conducted in the acute stage (<7 days after stroke) or the early subacute stage (>7 days–3 months after stroke), with the aim of improving severe upper limb motor impairments and disability. Data were extracted on the basis of the type and effect of rehabilitation interventions, and on the dosage (duration, frequency, session length, episode difficulty, and intensity). Study quality was assessed using the Physiotherapy Evidence Database Scale. Results. Twenty-three studies (1271 participants) with fair to good methodological quality were included. Only 3 studies were performed in the acute stage. Regardless of the type of intervention, upper limb rehabilitation was found to be beneficial for severe upper limb impairments and disability. Robotic therapy and functional electrical stimulation were identified as the most popular upper limb interventions; however, only a limited number of studies showed their superiority over a dose-matched control intervention for severe upper limb impairments in the subacute stage. A longer rehabilitation session length (<60 minutes) did not seem to have a larger impact on the magnitude of improved upper limb impairments. Conclusion. Different rehabilitation approaches seem to improve severe upper limb impairments and disability in the subacute stage after stroke; however, they are not distinctly superior to standard care or other interventions provided at the same dosage. Impact. Robotic therapy and functional electrical stimulation add variety to rehabilitation programs, but their benefit has not been shown to exceed that of standard care. Further research is necessary to identify the impact of dose (eg, intensity) on upper limb motor impairments and function, especially in the acute stage

    Background: Although aerobic training (AT) and resistance training (RT) are recommended after stroke, the optimal dosage of these interventions and their effectiveness on balance, walking capacity, and quality of life (QoL) remain conflicting. Objective: Our study aimed to quantify the effects of different modes, dosages and settings of exercise therapy on balance, walking capacity, and QoL in stroke survivors. Methods: PubMed, CINHAL, and Hinari databases were searched for randomised controlled trials (RCTs) evaluating the effects of AT and RT on balance, walking, and QoL in stroke survivors. The treatment effect was computed by the standard mean differences (SMDs). Results: Twenty-eight trials (n = 1571 participants) were included. Aerobic training and RT interventions were ineffective on balance. Aerobic training interventions were the most effective in improving walking capacity (SMD = 0.37 [0.02, 0.71], p = 0.04). For walking, capacity, a higher dosage (duration ≥ 120 min/week; intensity ≥ 60% heart rate reserve) of AT interventions demonstrated a significantly greater effect (SMD = 0.58 [0.12, 1.04], p = 0.01). Combined AT and RT improved QoL (SMD = 0.56 [0.12, 0.98], p = 0.01). Hospital located rehabilitation setting was effective for improving walking capacity (SMD = 0.57 [0.06, 1.09], p = 0.03) compared with home and/or community and laboratory settings. Conclusions: Our findings showed that neither AT nor RT have a significant effect on balance. However, AT executed in hospital-located settings with a higher dose is a more effective strategy to facilitate walking capacity in chronic stroke. In contrast, combined AT and RT is beneficial for improving QoL. Clinical implications: A high dosage of aerobic exercise, duration ≥ 120 min/week; intensity ≥ 60% heart rate reserve is beneficial for improving walking capacity

    Physical Activity Level, Barriers, and Facilitators for Exercise Engagement for Chronic Community-Dwelling Stroke Survivors in Low-Income Settings: A Cross-Sectional Study in Benin

    After a stroke incident, physical inactivity is common. People with stroke may perceive several barriers to performing physical activity (PA). This study aimed to document the PA level and understand the barriers and facilitators to engaging in PA for community-dwelling stroke survivors in Benin, a lower middle-income country. A cross-sectional study was conducted in three hospitals in Benin. Levels of PA were recorded by means of the Benin version of the International Physical Activity Questionnaire long form (IPAQ-LF-Benin), which is validated for stroke survivors in Benin. The perceived exercise facilitators and barriers were assessed by the Stroke Exercise Preference Inventory-13 (SEPI-13). A descriptive analysis and associations were performed with a Confidence Interval of 95% and <0.05 level of significance. A total of 87 participants (52 men, mean age of 53 ± 10 years, mean time after a stroke of 11 (IQR: 15) months and an average of 264.5 ± 178.9 m as distance on the 6 min walking test (6MWT) were included. Overall, stroke survivors in Benin reached a total PA of 985.5 (IQR: 2520) metabolic equivalent (METs)-minutes per week and were least active at work, domestic, and leisure domains with 0 MET-minutes per week. The overview of PA level showed that 52.9% of participants performed low PA intensity. However, 41.4% performed moderate PA or walking per day for at least five days per week. Important perceived barriers were lack of information (45.3%), hard-to-start exercise (39.5%), and travelling to places to exercise (29.9%). The preference for exercise was with family or friends, outdoors, for relaxation or enjoyment (90.2%), and receiving feedback (78.3%). Several socio-demographic, clinical, and community factors were significantly associated with moderate or intense PA (p < 0.05) in stroke survivors in this study. Our findings show that the PA level among chronic stroke survivors in Benin is overall too low relative to their walking capacity. Cultural factors in terms of the overprotection of the patients by their entourage and/or the low health literacy of populations to understand the effect of PA on their health may play a role. There is a need for new approaches that consider the individual barriers and facilitators to exercise

    Religion between State and Society

    In contrast to mainstream historiography, secularisation was not a distinct process in nineteenth-century Europe, since the century was a period of religious revival. In the late nineteenth century, in spite of weakening church attendance and rising agnosticism brought on by urbanisation and migration, religion remained attractive for the middle class and social movements related to church membership emerged in politics. In this chapter the diversity of religion in Europe is treated. The author distinguishes between hierarchical and nonhierarchical types of Christian churches, and between four religious regions in Europe. This situation had effects on the relationship between state and religion

    Bilateral versus unilateral upper limb training in (sub)acute stroke: A systematic and meta-analysis

    Get PDF
    Background: Integrating high dosage bilateral movements to improve upper limb (UL) recovery after stroke is a rehabilitation strategy that could potentially improve bimanual activities. Objectives: This study aims to compare the effects of bilateral with unilateral UL training on upper limb impairments and functional independence in (sub)acute stroke. Method: Five electronic databases (PubMed, Scopus, PEDro, ScienceDirect, Web of Science) were systematically searched from inception to June 2023. Randomised controlled trials comparing the effect of bilateral training to unilateral training in stroke survivors ( 6 months poststroke) were included. The treatment effect was computed by the standard mean differences (SMDs). Results: The review included 14 studies involving 706 participants. Bilateral training yielded a significant improvement on UL impairments measured by FMA-UE compared to unilateral training (SMD = 0.48; 95% CI: 0.08 to 0.88; P = 0.02). In addition, subgroup analysis based on the severity of UL impairments reported significant results in favour of bilateral UL training in improving UL impairments compared to unilateral training in “no motor capacity” patients (SMD = 0.66; 95% CI: 0.16 to 1.15; P = 0.009). Furthermore, a significant difference was observed in favour of bilateral UL training compared to unilateral UL training on daily activities measured by Functional Independence Measure (SMD = 0.45; 0.13 to 0.78; P = 0.006). Conclusion: Bilateral UL training was superior to unilateral training in improving impairments measured by FMA-UE and functional independence in daily activities measured by Functional Independence Measure in (sub)acute stroke. Clinical implications: Bilateral upper limb training promotes recovery of impairments and daily activities in (sub)acute phase of stroke

    Reliability of Upper Limb Pin-Prick Stimulation With Electroencephalography: Evoked Potentials, Spectra and Source Localization

    In order for electroencephalography (EEG) with sensory stimuli measures to be used in research and neurological clinical practice, demonstration of reliability is needed. However, this is rarely examined. Here we studied the test-retest reliability of the EEG latency and amplitude of evoked potentials and spectra as well as identifying the sources during pin-prick stimulation. We recorded EEG in 23 healthy older adults who underwent a protocol of pin-prick stimulation on the dominant and non-dominant hand. EEG was recorded in a second session with rest intervals of 1 week. For EEG electrodes Fz, Cz, and Pz peak amplitude, latency and frequency spectra for pin-prick evoked potentials was determined and test-retest reliability was assessed. Substantial reliability ICC scores (0.76–0.79) were identified for evoked potential negative-positive amplitude from the left hand at C4 channel and positive peak latency when stimulating the right hand at Cz channel. Frequency spectra showed consistent increase of low-frequency band activity (< 5 Hz) and also in theta and alpha bands in first 0.25 s. Almost perfect reliability scores were found for activity at both low-frequency and theta bands (ICC scores: 0.81–0.98). Sources were identified in the primary somatosensory and motor cortices in relation to the positive peak using s-LORETA analysis. Measuring the frequency response from the pin-prick evoked potentials may allow the reliable assessment of central somatosensory impairment in the clinical setting

    Translation of evidence-based Assistive Technologies into stroke rehabilitation: Users' perceptions of the barriers and opportunities

    Get PDF
    Background: Assistive Technologies (ATs), defined as "electrical or mechanical devices designed to help people recover movement", demonstrate clinical benefits in upper limb stroke rehabilitation; however translation into clinical practice is poor. Uptake is dependent on a complex relationship between all stakeholders. Our aim was to understand patients', carers' (P&Cs) and healthcare professionals' (HCPs) experience and views of upper limb rehabilitation and ATs, to identify barriers and opportunities critical to the effective translation of ATs into clinical practice. This work was conducted in the UK, which has a state funded healthcare system, but the findings have relevance to all healthcare systems. Methods. Two structurally comparable questionnaires, one for P&Cs and one for HCPs, were designed, piloted and completed anonymously. Wide distribution of the questionnaires provided data from HCPs with experience of stroke rehabilitation and P&Cs who had experience of stroke. Questionnaires were designed based on themes identified from four focus groups held with HCPs and P&Cs and piloted with a sample of HCPs (N = 24) and P&Cs (N = 8). Eight of whom (four HCPs and four P&Cs) had been involved in the development. Results: 292 HCPs and 123 P&Cs questionnaires were analysed. 120 (41%) of HCP and 79 (64%) of P&C respondents had never used ATs. Most views were common to both groups, citing lack of information and access to ATs as the main reasons for not using them. Both HCPs (N = 53 [34%]) and P&C (N = 21 [47%]) cited Functional Electrical Stimulation (FES) as the most frequently used AT. Research evidence was rated by HCPs as the most important factor in the design of an ideal technology, yet ATs they used or prescribed were not supported by research evidence. P&Cs rated ease of set-up and comfort more highly. Conclusion: Key barriers to translation of ATs into clinical practice are lack of knowledge, education, awareness and access. Perceptions about arm rehabilitation post-stroke are similar between HCPs and P&Cs. Based on our findings, improvements in AT design, pragmatic clinical evaluation, better knowledge and awareness and improvement in provision of services will contribute to better and cost-effective upper limb stroke rehabilitation. © 2014 Hughes et al.; licensee BioMed Central Ltd

    The effect of combining transcranial direct current stimulation with robot therapy for the impaired upper limb in stroke

    Neurological rehabilitation technologies such as Robot Therapy (RT) and noninvasive brain stimulation (NIBS) can promote motor recovery after stroke. The novelty of this research was to explore the feasibility and the effect of the combination method of NIBS called transcranial Direct Current Stimulation (tDCS) with uni-lateral and three-dimensional RT for the impaired upper limb (UL) in people with sub-acute and chronic stroke.This thesis involved three studies: (a) systematic review with meta-analyses (b) a pilot double-blinded randomised controlled trial with a feasibility component and (c) a reliability study of the measurement of Motor Evoked Potential (MEP) response using Transcranial Magnetic Stimulation in healthy adults. The first study involved a review of seven papers exploring the combination of tDCS with rehabilitation programmes for the UL in stroke. For the second study, stroke participants underwent 18 x one hour sessions of RT (Armeo®) over eight weeks during which they received 20 minutes real tDCS or sham tDCS. Outcome measures were applied at baseline, post-intervention and at three-month follow-up. The qualitative component explored the views and experiences of the participants of RT and NIBS using semi-structured interviews. The third study involved age-matched healthy adults exploring intrarater and test-retest reliability of the TMS assessment.Results of the three studies were the following: Seven papers were reviewed and a small effect size was found favouring real tDCS and rehabilitation programmes for the UL in stroke. 22 participants (12 sub-acute and 10 chronic) completed the pilot RCT. Participants adhered well to the treatment. One participant dropped out of the trial due to painful sensations and skin problems. The sub-acute and chronic groups showed a clinically significant improvement of 15.5% and 8.8% respectively in UL impairments at post-intervention from baseline. There was no difference in the effects of sham and anodal tDCS on UL impairments. Participants found the treatment beneficial and gave suggestions how to improve future research. In summary, the TMS assessment showed excellent reliability for measurement of resting motor threshold but poor to moderate reliability for MEP amplitude.In conclusion, it was indicated that RT may be of benefit in sub-acute and chronic stroke however, adding tDCS may not result in an additive effect on UL impairments and dexterity. The present study provided a power calculation for a larger RCT to be carried out in the future
