Background: Individuals having experienced a stroke need the help of an individual to perform their activities of daily living. Therefore, the disease affects not only patients but also their caregivers.

Objectives: This study aimed to investigate how aphasia affects caregivers' burden of care, quality of life, and occupational performance.

Methods: This cross-sectional study involved Group 1, (n=51) the caregivers of individuals having experienced a stroke with aphasia, and Group 2 (n = 51), the caregivers of individuals having experienced a stroke without aphasia. The caregivers were evaluated using the sociodemographic information form, the Zarit Caregiver Burden Scale, the SF-36 Short Form, and Canadian Occupational Performance Measure tests.

Results: Our study found that the caregiver burden in Group 1 was higher than in Group 2 (t = 3.8, p = 0.01). Caregivers in Group 1 also had higher pain levels (t = -2.21, p = 0.029) and lower social functions than those in Group 2 (t = -2.54, p = 0.013). There was no statistically significant difference between the other sub-parameters of quality of life (p > 0.05). It was observed that the occupational performance (t = -3.31, p = 0.001) and satisfaction levels (t = -3.57, p = 0.001) of the caregivers in Group 1 were lower than those of the caregivers in Group 2.

Conclusions: Occupational therapy evaluation and intervention programs for caregivers should consider the occupational performance of caregivers of individuals with aphasia and include approaches to problem areas.

Background: This study aimed to evaluate the clinical efficacy and safety of inspiratory and expiratory muscle training (IEMT) for patients who underwent tracheostomy after stroke.

Methods: The study was an investigator-initiated, single-center, two-arm, evaluator-blinded, randomized clinical trial conducted at West China Hospital of Sichuan University, China, from January 2022 to June 2022. The patients were randomly divided into the intervention group and control group. Patients in both groups received conventional clinical, rehabilitation treatment and usual care. The intervention group also received IEMT for three weeks. There were three primary outcomes including maximal inspiratory pressure (MIP, cmH₂O), maximal expiratory pressure (MEP, cmH2O) and decannulation outcome after intervention (n, %). The secondary outcomes were other respiratory function outcomes, motor function, activities of daily living (ADL), quality of life (QoL) and the new pulmonary infection rate after the intervention at three weeks.

Results: A total of 50 participants were enrolled [25 in each group; 39 (78%) were men; mean (SD) age, 55.94 (11.97) years]. At three weeks, significant differences were found in the MIP [control vs IEMT: 39.04 (6.21) vs 56.28 (10.41), p < 0.001]; MEP [43.48 (5.36) vs 62.16 (10.18), p < 0.001], and tracheal tube extraction success rate [2 (8%) vs 9 (36%), p = 0.019] between the two groups. In addition, the new pulmonary infection rate in the intervention groups were significantly different (all p < 0.05) from those in the control group.

Conclusions: IEMT can improve respiratory function, decannulation outcome, among patients with tracheostomy after stroke.

Background: Research has demonstrated that adults post-stroke may experience sensory impairments across different sensory systems. There is a gap in research describing how sensory changes after stroke affect participation in health promoting activities.

Objectives: The purpose of this study is to understand how changes in sensory health after stroke affect participation in meaningful activities.

Methods: We adopted a qualitative phenomenological design to conduct four focus groups with ten participants: two focus groups with a cohort of adults post-stroke (n=5) and two focus groups with a cohort of stroke rehabilitation therapists and stroke caregivers (n=5). Focus group transcripts were coded using open and focused coding with NVivo software to develop themes.

Results: Participants reported changes in their visual, vestibular, proprioceptive, olfactory, gustatory, tactile, and auditory systems that affected their participation in meaningful activities. Participants also reported that they experienced insufficient resources and therapies addressing their sensory health after their stroke. Analyses yielded the following themes:(1) it's hidden and invisible;(2) sensory changes affect participation and can be overwhelming; and (3) it's easy to stay inside: sensory changes negatively affect social participation.

Conclusions: Adults post-stroke experience sensory changes that restrict their participation in meaningful activities including social activities; however, these changes were often missed. More research is needed to further explore the impact of changes in sensory health and understand needs regarding the development of assessment tools and intervention protocols to address the sensory health of adults post-stroke in the clinic, home, and community.

Background: Post-Stroke Dysphagia (PSD) is a common complication that significantly affects the quality of life and health outcomes of stroke survivors. Traditional treatments often have limitations, necessitating the exploration of new therapeutic approaches. This systematic review and meta-analysis aimed to evaluate the efficacy of intermittent Theta Burst Stimulation (iTBS) as an innovative treatment for PSD.

Methods: Following the PRISMA guidelines, a comprehensive literature search was conducted in PubMed, Embase, and Cochrane Library up to July 2024. Studies included were randomized controlled trials (RCTs) involving stroke patients with confirmed dysphagia, comparing iTBS to control treatments. Data extraction and quality assessment were performed independently by two reviewers using the Cochrane RoB 2 tool. Primary outcomes were changes in the Penetration-Aspiration Scale (PAS) and Swallowing Severity Scale (SSA). Meta-analyses were conducted using Review Manager (RevMan) 5.4.

Results: Four RCTs with a total of 199 participants were included. iTBS significantly improved SSA (MD = -3.26, 95% CI [-4.66, -1.86], p < 0.001) and PAS (MD = -1.67, 95% CI [-2.49, -0.86], p < 0.001) immediately after treatment compared to sham stimulation. No significant adverse events were reported.

Conclusion: iTBS appears to have a positive immediate effect on improving swallowing function and reducing aspiration risk in PSD patients compared to sham stimulation. However, these effects may not persist in the long term, and further large-scale RCTs are needed to confirm these findings and establish standardized treatment protocols.

Background: Post-stroke lateropulsion is prevalent and associated with poor rehabilitation outcomes; however, data regarding long-term function associated with lateropulsion are lacking.

Objectives: This study aimed to explore lateropulsion resolution and associations between lateropulsion, functional outcomes, and fall occurrence up to 12 months post-stroke.

Methods: Participants for this prospective, longitudinal cohort study were recruited from a Stroke Rehabilitation Unit (SRU). Assessments were conducted at SRU admission, at discharge, and at three, six, nine, and twelve months post-stroke. Outcomes included the Four-Point Pusher Score (4PPS), Functional Independence Measure (FIM), and fall occurrence. Longitudinal outcomes were modeled using generalized linear mixed-effects models.

Results: The final analyses included data from 144 participants. Eighty-two participants (56.9) had lateropulsion (4PPS ≥ 1) on admission. Odds of resolved lateropulsion (4PPS = 0) increased longitudinally from discharge for people who participated in rehabilitation physiotherapy (OR: 9.7, 28.1, 43.1, 81.3: <0.001 at three, six, nine, and twelve months respectively). The greatest FIM improvement among participants in all 4PPS categories occurred during the SRU inpatient phase. The probability of falls post-discharge was greatest among participants with 4PPS = 1 at three months, when compared with 4PPS = 0 (p= 0.022).

Conclusions: This study showed that lateropulsion can continue to resolve up to one year post-stroke. Earlier lateropulsion resolution was associated with ongoing rehabilitation physiotherapy participation. Long-term functional gains were maintained among people discharged home, whereas functional status deteriorated after six months among those in residential care. Study findings will allow rehabilitation and service providers to better plan for and accommodate the long-term rehabilitation and care needs of people with post-stroke lateropulsion.

Aim: The aim of this study was to make the Turkish cultural adaptation of the the Stroke Activity Scale (SAS).

Method: This study was designed as a methodological research. The psychometric properties of the SAS scale were evaluated by validity and reliability analyses.

Results: The average age of 84 stroke patients (mean ± SD) was 59.52 ± 14.03 years. Kaiser-Meyer-Olkin (0.816) and Bartlett's Test of Sphericity (χ2 = 288.968, df = 10, p < 0.001) showed that the data set can be factored. A one-factor structure was obtained with Principal Component Analysis (PCA). The factor loads of the items obtained with PCA and Confirmatory Factor Analysis (CFA) were found to be statistically significant. The obtained chi-square statistics (χ2 = 2.227, p = 0.694), normalized chi-square/freedom (χ2/sd) value (0 ≤ 0.557 ≤ 2) and other goodness of fit indices showed good compliance. The positive highly significant correlation (r = 0.846, p < 0.001) between the SAS and Rivermead Mobility Index (RMI) scales confirmed the Concurrent validity. Cronbach's alpha (0.864) value showed high reliability and Intraclass Correlation Coefficient (ICC) value (0.983, p < 0.001) showed excellent agreement.

Conclusions: In this study, which was conducted for the Turkish adaptation of the SAS scale, the 5-item and 1-factor structure was evaluated as a valid and reliable scale for evaluating the balance abilities of stroke patients living in Turkey.

Background: Research on cardiorespiratory fitness (CRF) in relation to physical activity (PA) and fatigue after stroke is limited. Increased knowledge of interrelationships between these factors can help optimize rehabilitation strategies and improve health-outcomes.

Objectives: We aimed to: 1) evaluate CRF, PA, and fatigue, 2) characterize patients with impaired versus non-impaired CRF, and 3) examine associations of CRF with PA and fatigue, three months after first-ever ischemic stroke.

Methods: In this cross-sectional study CRF was measured as peak oxygen uptake (VO_2peak) by cardiopulmonary exercise testing. PA was measured using accelerometers. Fatigue was assessed with the 7-item Fatigue Severity Scale (FSS).

Results: The sample (n=74, mean age 64±13 years, 36% women) had a mean VO_2peak of 27.0±8.7 (86% of predicted). Fifty-one percent met the World Health Organization's recommendation of ≥150 min of moderate PA/week. Mean steps-per-day was 9316±4424 (113% of predicted). Thirty-five percent of the sample had moderate-to-high fatigue (FSS≥4), mean FSS score was 3.2±1.8.  Patients with impaired CRF (VO_2peak<80% of predicted) had higher body-fat-percent (p<0.01), less moderate-to-vigorous PA (MVPA) (p<0.01) and a trend toward higher fatigue (p=0.053) compared to the non-impaired. Backward regression analysis showed that higher CRF was associated with more MVPA (unstandardized beta [95% CI]: 0.38 [0.15, 0.63], p=0.002) and less fatigue (unstandardized beta [95% CI]: -3.9 [-6.4, -1.6], p=0.004).

Conclusions: Stroke patients had lower CRF compared to reference values. Impaired CRF was mainly related to overweight. Higher CRF was associated with more MVPA and less fatigue. Exercise after stroke may be especially beneficial for patients with impaired CRF.

Background: Drop foot is common post-stroke, elevating fall risks and mobility limitations. It is caused by weakness and lack of control of the tibialis anterior muscle (TA), for which various rehabilitation treatments are used. A reliable objective estimate of changes in TA muscle morphology and composition can enhance treatment optimization.

Objectives: We aimed to ascertain 3D freehand ultrasound (3DfUS) reliability in measuring TA muscle volume, length, and echo intensity in stroke patients and healthy controls and its validity by comparing these features across legs, between patients and controls, and between clinical subgroups (i.e. patients with and without ankle contracture, spastic muscle overactivity, and foot dorsiflexor paresis).

Methods: We included 9 stroke patients and 9 healthy controls to define reliability and 26 stroke patients and 28 healthy controls to define validity. For reliability, data were collected and processed by 2 different operators and processors. For inter- and intra-rater reliability, intra-class correlation coefficient (ICC) and standard error of measurement (SEM) were used. For validity, Wilcoxon-Signed-Ranked and Mann-Whitney U tests were used for comparisons between groups and subgroups.

Results: All measurements showed good to excellent inter- and intra-rater reliability (ICC: 0.816 to 0.997, SEM: 0.5% to 7.8%). Comparison analyses revealed no differences in muscle features among legs, groups, or subgroups.

Conclusion: While the 3DfUS is a reliable method to define TA morphology and composition, its clinical validity needs further investigation into factors influencing muscle property changes across various age groups and post-stroke time points.

Background: Balance self-efficacy is a strong predictor of fall risk after stroke and is related to performance on balance and walking tests. The use of telerehabilitation for delivering stroke rehabilitation has increased in recent years and there is a need to adapt common clinical assessments to be administered in virtual formats, but the association between balance self-efficacy and virtually administered clinical tests of balance performance has yet to be established. This study examined the association between the Activities-specific Balance Confidence (ABC) Scale and virtually administered Timed Up and Go (TUG), Tandem Stand, and Functional Reach tests (FRT) in individuals with stroke.

Methods: This was a secondary analysis of baseline data from two telerehabilitation trials with individuals with stroke. All assessments were administered by trained physical therapists through videoconferencing software. Multivariate regression analyses were used to examine the associations between the ABC scale and TUG test, Tandem Stand test, and FRT, adjusted for age and number of comorbidities.

Results: Data from 51 participants (n = 11 female, median age = 64 [IQR: 18] years, 9.3 ± 4.6 months poststroke) were analyzed. The ABC scores were associated with TUG (R² = 0.56, F(3,47) = 20.26, p < 0.01), but not Tandem Stand (R² = 0.18, F(5,45) = 1.93, p = 0.11) or FRT (R² = 0.14, F(3,47) = 2.55, p = 0.07) tests.

Conclusion: We observed associations between the ABC scores and virtual TUG, but not with Tandem Stand or FRT, which may be attributed to the context-specificity of balance self-efficacy. As virtual administration of outcomes assessments becomes part of common practice in stroke rehabilitation, our study supports the use of virtually administered TUG in stroke.

Background: Physical activity decreases after stroke due to various factors and the causes and effects of these factors remain unclear.

Objectives: This study aimed todetermine the effects of kinesiophobia, fatigue, and quality of life on physical activity in patients with stroke.

Methods: The study included 32 patients (13 females/19 males), all evaluated using the Stroke Rehabilitation Assessment of Movement, Barthel Index, Tampa Kinesiophobia Scale-fatigue, Fatigue Impact Scale and Stroke-Specific Quality of Life Scale. The SenseWear multisensory activity monitor was worn on the arm of the patients for 1 week to evaluate active energy expenditure, step count, and rest periods in relation to physical activity. Multiple linear regression analysis was used to examine the effects of the independent variables kinesiophobia, fatigue, and quality of life on the dependent variables of active energy expenditure, step count, and rest periods.

Results: The mean age of the patients was 52.31 ± 14.76 years. According to the multiple regression analysis results, kinesiophobia (p = 0.011) and quality of life (p = 0.009) are significant determinants of active energy expenditure and quality of life (p = 0.001) is a significant determinant of the step count in patients with stroke. Kinesiophobia, fatigue, and quality of life were not determinants of rest periods (p > 0.05).

Conclusions: The study results showed that kinesiophobia and quality of life are important determinants of physical activity in patients with stroke. Combined evaluation in the clinic of motor findings and non-motor factors, which are often ignored, and the application of target-oriented approaches to these problems will make a significant contribution to the success of stroke rehabilitation.
