Background: Virtual reality (VR) is becoming a popular alternative to traditional upper and lower limb rehabilitation following a stroke.

Objective: To conduct a systematic review and meta-analysis on the effectiveness of VR interventions for improving balance in a chronic stroke (≥6 months) population.

Data sources: A literature search of Pubmed, Scopus, CINAHL, Embase, Psycinfo, and Web of Science databases was conducted.

Study selection: English randomized controlled trials published up to September 2015 assessing balance with VR in chronic stroke participants.

Data extraction: Mean and standard deviations from outcome measures were extracted. Pooled standard mean differences ± standard error were calculated for the Berg Balance Scale (BBS) and the Timed Up and Go test (TUG).

Results: In total, 20 studies were selected which assessed the Nintendo® Wii Fit balance board (n = 7), treadmill training and VR (n = 7), and postural training using VR (n = 6). Significant improvements were found for VR interventions evaluating the BBS (n = 12; MD = 2.94 ± 0.57; p < 0.001) and TUG (n = 13; MD = 2.49 ± 0.57; p < 0.001). Sub-analyses revealed postural VR interventions had a significant effect on BBS (n = 5) and TUG (n = 3) scores (BBS: MD = 3.82 ± 0.79; p < 0.001 and TUG: MD = 3.74 ± 0.97; p < 0.001). VR and treadmill training (n = 5) had a significant effect on TUG scores (MD = 2.15 ± 0.89, p = 0.016).

Conclusion: Overall, VR interventions compared to conventional rehabilitation had significant improvements. The meta-analyses also suggest that the Nintendo® Wii Fit balance board may not be effective, although further confirmatory studies are necessary. Results should be interpreted with caution due to differences in therapy intensities and effect sizes within the included studies.  相似文献

Background: Constraint-induced movement therapy (CIMT) is suggested to reduce functional asymmetry between the upper limbs after stroke. However, there are few studies about CIMT for lower limbs.

Objective: To examine the effects of CIMT for lower limbs on functional mobility and postural balance in subjects with stroke.

Methods: A 40-day follow-up, single-blind randomized controlled trial was performed with 38 subacute stroke patients (mean of 4.5 months post-stroke). Participants were randomized into: treadmill training with load to restraint the non-paretic ankle (experimental group) or treadmill training without load (control group). Both groups performing daily training for two consecutive weeks (nine sessions) and performed home-based exercises during this period. As outcome measures, postural balance (Berg Balance Scale – BBS) and functional mobility (Timed Up and Go test – TUG and kinematic parameters of turning – Qualisys System of movement analysis) were obtained at baseline, mid-training, post-training and follow-up.

Results: Repeated-measures ANOVA showed improvements after training in postural balance (BBS: F = 39.39, P < .001) and functional mobility, showed by TUG (F = 18.33, P < .001) and by kinematic turning parameters (turn speed: F = 35.13, P < .001; stride length: F = 29.71, P < .001; stride time: F = 13.42, P < .001). All these improvements were observed in both groups and maintained in follow-up.

Conclusions: These results suggest that two weeks of treadmill gait training associated to home-based exercises can be effective to improve postural balance and functional mobility in subacute stroke patients. However, the load addition was not a differential factor in intervention.  相似文献

Background: Patients with acute stroke spend most of their hospital day inactive. However, a method to promote physical activity (PA) in stroke has not been established.

Objective: To evaluate the effectiveness of promoting PA by enhancing self-efficacy in hospitalized patients with mild ischemic stroke.

Design: Pre–post interventional study.

Methods: Hospitalized patients with mild ischemic stroke who could walk without assistance were recruited. We measured the daily number of steps taken as the index of daily hospitalized PA using an accelerometer. At the baseline measurement, patients did not receive accelerometer-based feedback. To promote hospitalized PA, a physical therapist provided instruction on the self-monitoring approach and discussed PA targets, encouraged the patients to walk more, and instructed them on the importance of PA after stroke. We also measured self-efficacy for PA using an assessment tool at the baseline and during the intervention.

Results: Twenty-two patients (62.5 years old, 68.2% men) were included. PA during the intervention was higher than that at the baseline measurement (5709.4 ± 2236.1 vs. 2813.9 ± 1511.9 steps/day, p < 0.001). Self-efficacy for PA during the intervention was also higher than that at the baseline measurement (76.4 ± 18.8 vs. 58.9 ± 29.0 points, p < 0.001).

Conclusions: Promoting PA by enhancing self-efficacy may increase PA and self-efficacy for PA in hospitalized patients with mild ischemic stroke. The present results might provide new strategies of PA promotion in these hospitalized patients.  相似文献

Background: Several reports have focused on the effects of whole body vibration (WBV) on spasticity with differing results. Most studies used modified Ashworth scale (MAS) for qualitative measurements, but the effect was small.

Objective: To investigate the effect of WBV on spasticity in hemiplegic legs of patients with stroke using F-wave parameters.

Methods: Sixteen patients with stroke (mean age, 54.7 ± 13.5 years: time after stroke, 28.0 ± 26.3 months) were enrolled in a comparative before-and-after intervention trial. WBV was applied at 30 Hz (4–8 mm amplitude) for 5 min on the hamstrings, gastrocnemius, and soleus muscles in a sitting position. Spasticity was assessed according to the F-wave parameters, MAS, and active and passive range of motion (A-ROM and P-ROM, respectively). These assessments were obtained before, immediately after, and 20 min after each intervention.

Results: The F-wave parameters, MAS score, and P-ROM improved significantly after the WBV and remained below the baseline level, even after 20 min; no such change was noted in the unaffected limb via the F-wave parameters. The WBV also improved volitional movement immediately after intervention, as indicated by the A-ROM.

Conclusions: These results confirmed a significant reduction of motor neuron excitability until 20 min after the WBV, as indicated by F-wave parameters.  相似文献

Background: Robot-assisted gait training (RAGT) is effective for improving dynamic balance and aerobic capacity, but previous RAGT method does not set suitable training intensity. Recently, high-intensity treadmill gait training at 70% of heart rate reserve (HRR) was used for improving aerobic capacity and dynamic balance.

Purpose: This study was designed to compare the effectiveness between objective and subjective methods of high-intensity RAGT for improving dynamic balance and aerobic capacity in chronic stroke.

Methods: Subjects were randomly allocated into experimental (n = 17) and control (n = 17) groups. The experimental group underwent high-intensity RAGT at 70% of HRR, whereas the control group underwent high-intensity RAGT at an RPE of 15. Both groups received their assigned training for 30 min per session, 3 days per week for 6 weeks. All subjects also received an additional 30 min of conventional physical therapy. Before and after each of the 18 sessions, the dynamic balance and aerobic capacity of all subjects were evaluated by a blinded examiner.

Results: After training, Berg Balance Scale (BBS) and Timed Up and Go Test scores, VO2max, and VO2max/kg were significantly increased in both groups (p < 0.05). These variables in experimental group were significantly greater than control group. However, the BBS score was not significantly different between both groups. All subjects completed high-intensity RAGT. No adverse effect of training was observed in both groups.

Conclusion: High-intensity RAGT at 70% of HRR significantly improved dynamic balance and aerobic capacity more than RAGT at RPE of 15. These results suggest that high-intensity RAGT at 70% of HRR is safe and effective for improving dynamic balance and aerobic capacity in chronic stroke.  相似文献

Background: The changes effected by the inspiratory muscle training (IMT) on the structure of inspiratory muscles such as on the diaphragm, in patients with stroke, is unclear.

Objective: To investigate the effect of IMT on inspiratory function, diaphragm thickness, walking endurance, and fatigue in patients with stroke.

Methods: A total of 30 patients with stroke were randomized to either the experimental group or the control group. The experimental group (n = 15) underwent inspiratory muscle training with resistance adjusted to 30% of maximal inspiratory pressure, 90 breaths a day, 5 times a week for 6 weeks. Both groups received regular physical therapy for the same amount of time. The primary outcome measure was the diaphragm thickness ratio. The secondary outcomes were inspiratory function; maximal inspiratory pressure and inspiratory muscle endurance; and gait endurance and fatigue.

Results: There were significant differences between the two groups in the thickness ratio on the affected diaphragm thickness (medium effect size), maximal inspiratory pressure (medium effect size), and inspiratory muscle endurance (large effect size; Bonferroni correction p < 0.005). The gait endurance (medium effect size) and fatigue (small effect size) showed no significant differences in the between group comparison.

Conclusion: Inspiratory muscle training was effective in improving respiratory function and inducing structural changes, especially in the affected diaphragm.  相似文献

Background: The Assessment of Living with Aphasia (ALA) is a pictographic, self-report measure of aphasia-related quality of life (QoL). It has yet to be used in the Singapore population or adapted to other languages.

Aims: To examine the reliability and validity of the ALA and develop a Mandarin Chinese adaptation, the ALA-C, in the Singapore context.

Methods & procedures: Linguistic validation of the ALA was conducted to derive the ALA-C. People with aphasia (PWA) who were at least 6 months post-onset underwent the ALA/ALA-C and a series of reference measures in their dominant language (English/Mandarin). Test–retest reliability was evaluated using intra-class correlations and internal consistency using Cronbach’s alpha. Eight reference measures were administered to assess construct validity.

Outcomes & results: Sixty-six PWA were recruited to the study. Both the ALA and ALA-C showed excellent internal consistency (α = 0.97/0.96) and test–retest reliability (intraclass correlation = 0.97/0.98), and acceptable convergent (= 0.63–0.83 and 0.70–0.83 respectively) and discriminant (r = 0.45–0.60 and 0.39–0.53, respectively) validity.

Conclusions: Both ALA and ALA-C demonstrated excellent reliability and good validity. Further research is warranted to examine use by more practicing clinicians and with more participants of varying degrees of aphasia severity to enable additional investigation of its psychometric properties.  相似文献

Introduction: Metabolic acidosis with increasing lactate concentration develops due to the lack of oxygen in the tissues.

Objectives: The effect of lactic acidosis on neurological development in the first year of life.

Materials and Methods: Our study included 50 newborns with perinatal hypoxia requiring oxygen therapy and 50 healthy newborns. pH, pCO2, pO2, base excess (BE) and lactates from arterialized capillary blood were determined in both groups of newborns, in the first and second hours after birth, and neurological development in the first year of life was estimated.

Results: pH, pCO2, pO2, BE and lactates differed significantly between the groups in the first and second hours after birth p < 0.01. Hypotonia was recorded in 20/50 cases and hypertonia was recorded in 10/50 cases in the first year of life.

Conclusion: Lactate concentration may be an indicator of neurological damage in neonates with perinatal hypoxia.  相似文献

Background: Immobilization of the extremities after stroke is known to be the foremost reason of articular cartilage degeneration and musculoskeletal ultrasound (US) has become increasingly important in the assessment of joint cartilage. To the best of our knowledge, US measurements of the metacarpal and talar cartilage thicknesses in hemiplegic patients after stroke have not been performed before.

Objectives: The aim of the study was to explore whether metacarpal and talar cartilage thicknesses were affected after stroke using US.

Methods: Fifty-eight patients (33 M and 25 F) with unilateral hemiplegia after stroke were enrolled between April and June 2015. Age, sex, body mass index, paretic side, and underlying etiology (ischemic or hemorrhagic) were noted. Modified Ashworth scale, Brunnstrom motor recovery stage (BMRS), motor functional independence measure and functional ambulation category were recorded. A 5–12 MHz linear array probe was used for ultrasonographic cartilage measurements at 2nd, 3rd, and 4th metacarpal heads and talus.

Results: When compared with the non-paretic side, metacarpal (but not talar) cartilage thicknesses were found to be less on the paretic side (significant for the 3rd and 4th ones) (both p < 0.05). Subgroup analysis yielded thinner 3rd and 4th metacarpal cartilage thicknesses between the groups in patients with BMRS 1–3 (p = 0.009 and 0.054, respectively) but not in patients with BMRS 4–6 (p = 0.416 and 0.571, respectively).

Conclusions: We may conclude that metacarpal (but not talar) cartilage is thinner on the paretic side of stroke patients that seems to be less with better motor functioning.  相似文献

Background: Early diagnosis and proper monitoring of intracranial pressure (ICP) in idiopathic intracranial hypertension (IIH) could reduce morbidity.

Objectives: The objective was to explore and monitor reflection of raised ICP in IIH on optic nerve sheath diameter (ONSD), papillary height and ophthalmic vessels hemodynamics, using transorbital sonography (TOS).

Methods: The study included 24 IIH patients and 30 controls. Patients were compared to controls (phase I) then reassessed twice; 1 week and 4 weeks later (phase II). Both groups underwent clinical evaluation and TOS to measure ONSD, papillary elevation, and color Doppler indices of the ophthalmic vessels. Patients underwent lumbar puncture (LP) to measure cerebrospinal fluid (CSF) pressure.

Results: ONSD was significantly higher in patients compared to controls (p < 0.001). The cut-off value was 6.2 mm. Papillary elevation (p = 0.006) and ONSD (p = 0.006) were significantly reduced 4 weeks following LP. Baseline color Doppler indices of the ophthalmic vessels were comparable between both groups and the changes observed during the follow-up visits in the patients were insignificant.

Conclusion: Reflected ICP changes on ONSD and papilla, measured by TOS, could be a valuable noninvasive additional tool to diagnose and monitor IIH patients. IIH insignificantly influences ophthalmic vessels hemodynamics.

Objective: This study aimed to introduce a modified animal model of middle cerebral arterial occlusion (MCAO) through placement of intraluminal spindle-shaped head suture by comparing the traditional MCAO model.

Methods: A total of 60 male Spraque-Dawley (SD) rats were divided into two groups and MCAO was induced using spindle-shaped head suture or round head suture. The mortality, infarct volume, neurological function, success rate of the surgery, and stability of modeling were examined to evaluate the effectiveness of this model.

Results: Our results showed the success rate was 90.0% in spindle-shaped head group and 83.3% in round head group showing no significant difference; spindle-shaped head achieved a better establishment of MCAO model as shown in neurological examination. The infarct volume was 31.99 ± 5.44% in spindle-shaped head group and was significantly higher than in round head group (24.59 ± 7.17%; p < 0.05), and the coefficient of variation of infarct volume in spindle-shaped head group was lower than in round head group.

Conclusion: Our findings indicate that the modified suture induces a more reproducible and stable ischemic stroke following MCAO in SD rats.  相似文献

Background: Stroke survivors experience greater strength deficits during finger extension than finger flexion. Prior research indicates relatively little observed weakness is directly attributable to muscle atrophy. Changes in other muscle properties, however, may contribute to strength deficits.

Objectives: This study measured muscle fiber conduction velocity (MFCV) in a finger flexor and extensor muscle to infer changes in muscle fiber-type after stroke.

Methods: Conduction velocity was measured using a linear EMG surface electrode array for both extensor digitorum communis and flexor digitorum superficialis in 12 stroke survivors with chronic hand hemiparesis and five control subjects. Measurements were made in both hands for all subjects. Stroke survivors had either severe (n = 5) or moderate (n = 7) hand impairment.

Results: Absolute MFCV was significantly lower in the paretic hand of severely impaired stroke patients compared to moderately impaired patients and healthy control subjects. The relative MFCV between the two hands, however, was quite similar for flexor muscles across all subjects and for extensor muscles for the neurologically intact control subjects. However, MFCV for finger extensors was smaller in the paretic as compared to the nonparetic hand for both groups of stroke survivors.

Conclusions: One explanation for reduced MFCV may be a type-II to type-I muscle fiber, especially in extrinsic extensors. Clinically, therapists may use this information to develop therapeutic exercises targeting loss of type-II fiber in extensor muscles.  相似文献

Background: Spasticity is a motor disorder that is commonly treated manually by a physical therapist (PhT) stretching the muscles. Recent data on learning have demonstrated the importance of human-to-human interaction in improving rehabilitation: cooperative motor behavior engages specific areas of the motor system compared with execution of a task alone.

Objectives: We hypothesize that PhT-guided therapy that involves active collaboration with the patient (Pt) through shared biomechanical visual biofeedback (vBFB) positively impacts learning and performance by the Pt during ankle spasticity treatment. A sensorized ankle foot orthosis (AFO) was developed to provide online quantitative data of joint range of motion (ROM), angular velocity, and electromyographic activity to the PhT and Pt during the treatment of ankle spasticity.

Methods: Randomized controlled clinical trial. Ten subacute stroke inpatients, randomized into experimental (EXP) and control (CTRL) groups, underwent six weeks of daily treatment. The EXP group was treated with an active AFO, and the CTRL group was given an inactive AFO. Spasticity, ankle ROM, ankle active and passive joint speed, and coactivation index (CI) were assessed at enrollment and after 15–30 sessions.

Results: Spasticity and CI (p < 0.005) decreased significantly after training only in the EXP group, in association with a significant rise in active joint speed and active ROM (p < 0.05). Improvements in spasticity (p < 0.05), active joint speed (p < 0.001), and CI (p < 0.001) after treatment differed between the EXP and CTRL groups.

Conclusions: PhT–Pt sharing of exercise information, provided by joint sensorization and vBFB, improved the efficacy of the conventional approach for treating ankle spasticity in subacute stroke Pts.  相似文献

Background: Aphasia is a serious consequence of stroke but aphasics patients have been routinely excluded from participation in some areas of stroke research.

Objective: To assess the role of specific linguistic and non-verbal cognitive abilities on the short-term motor recovery of patients with aphasia due to first-ever stroke to the left hemisphere after an intensive rehabilitation treatment.

Methods: 48 post-acute aphasic patients, who underwent physiotherapy and speech language therapy, were enrolled for this retrospective cohort-study. Four types of possible predictive factors were taken into account: clinical variables, functional status, language and non-verbal cognitive abilities. The motor FIM at discharge was used as the main dependent variable.

Results: Patients were classified as follows: 6 amnestic, 9 Broca’s, 7 Wernicke’s, and 26 global aphasics. Motor FIM at admission (p = 0.003) and at discharge (p = 0.042), all linguistic subtests of Aachener AphasieTest (p = 0.001), and non-verbal reasoning abilities (Raven’s CPM, p = 0.006) resulted significantly different across different types of aphasia. Post-hoc analyses showed differences only between global aphasia and the other groups. A Multiple Linear Regression shows that admission motor FIM (p = 0.001) and Token test (p = 0.040), adjusted for clinical, language, and non-verbal reasoning variables, resulted as independent predictors of motor FIM scores at discharge, while Raven’s CPM resulted close to statistical significance.

Conclusions: Motor function at admission resulted as the variable that most affects the motor recovery of post-stroke patients with aphasia after rehabilitation. A linguistic test requiring also non-linguistic abilities, including attention and working memory (i.e. Token test) is an independent predictor as well.  相似文献

Introduction: Recent genome-wide association studies have explored some new loci in association with Parkinson’s disease (PD). RAB7L1 is an important gene involved in one of the important neurological pathways, located in PARK16 locus. We performed a case-control study to examine the association between rs823144 SNP located in the promoter region of the RAB7L1 gene and PD risk in Iranian population.

Methods: A total of 960 samples including 480 PD patients and 480 healthy controls were collected for analysis of the RAB7L1 rs823144 polymorphism using polymerase chain reaction-restriction fragment length polymorphism (PCR – RFLP) method.

Results: We found significant differences in genotypic and allelic frequencies between patients and controls. Significant association was found between presence of minor allele (C) and decreased risk of PD development (p = 0.008, OR = 0.74 (0.605–0.924)). Also another significant association was observed between the CC genotype and PD (p = 0.004, OR = 0.441 (0.252–0.772)).

Conclusion: Our data support the association between rs823144 and decreased risk of PD.  相似文献

Background: Despite extensive study of the impact of stroke on muscle and functional performance, questions remain regarding the extent to which changes are due to the neurological injury vs. age-related loss of morphology and force production.

Objectives: To synthesize available evidence describing post-stroke changes in lower extremity muscle size and strength compared to healthy adults.

Methods: Scientific literature was searched up to April 2016 to identify studies that included lower extremity muscle size and strength measures in individuals with chronic stroke. Lower extremity muscle size and strength data from healthy controls were sought for comparison. Relative differences were calculated between paretic, nonparetic, and control limbs.

Results: Fifteen studies with 375 participants (61% male; age = 62 ± 5 years; time since stroke = 60 ± 42 months) were included. The paretic limb exhibited deficits of ~13% in thigh muscle size, ~5% in lower leg muscle size, and ~8% in lean leg mass compared to the nonparetic limb. Paretic plantarflexor and knee extensor strength were 52 and 36% lower, respectively, compared to the nonparetic limb. When compared to age-matched control data, both paretic and nonparetic limbs showed deficits in muscle size and strength.

Conclusions: Age-related differences support the impact of stroke-related sarcopenia as a contributor to hemiparetic muscle dysfunction. Understanding these muscular changes is necessary for designing appropriate exercise interventions aimed at restoring muscle function.  相似文献

Introduction: Homocysteine increase and glutathione derivative cysteinyl-glycine fall are indirect biomarkers for oxidative stress, for instance due to dopamine D1 receptor stimulation.

Objectives: To investigate the influence of the D1 receptor agonists levodopa and rotigotine compared with placebo on homocysteine and cysteinyl-glycine in plasma of patients with Parkinson’s disease.

Methods: Patients received 100 mg levodopa, 4 mg rotigotine or placebo. Cysteinyl-glycine and homocysteine were measured every 30 min over three hours.

Results: Homocysteine rose during levodopa- and placebo administration. Rotigotine had no effect. Cysteine-glycine only increased after placebo- but not after levodopa- or rotigotine.

Discussion: Homocysteine elevation results from hepatic and gastrointestinal methylation processes. Transdermal rotigotine circumvents these methylation locations. Turnover of segregated alkyl residuals from rotigotine serves as methyl group donors, which counteract homocysteine increment. The placebo-related cysteinyl-glycine increase results from reduced free radical exposure. Low levodopa dosing and antioxidants in the rotigotine patch matrix prevented cysteinyl-glycine fall.  相似文献

Background: Mild stroke comprises 53% of stroke hospital admissions; however, the majority of those with mild stroke patients receive little support to address chronic symptoms following stroke.

Objectives: To evaluate the feasibility and preliminary effect of the Chronic Disease Self-Management Program (CDSMP) for use with individuals immediately post mild-stroke.

Methods: Single-blind, exploratory, randomized controlled trial with participants who sustained a mild stroke (NIHSS <6). Participants were randomized to either receive the CDSMP intervention or to an inactive control group. Primary outcomes were self-reported health and self-efficacy and were obtained at baseline, post-intervention (treatment group only), and at six months post-baseline. Wilcoxon Signed Rank Tests were used to compare change score differences for all participants and effect size was computed using effect size r for non-parametric data.

Results: There were no differences between groups in demographics or baseline data with the exception of how participants felt they are able to manage their health in general (p = 0.05). At follow-up, effect sizes ranged from 0 to 0.35 (no effect to medium effect); however, while the treatment group reported improvements in several areas of health at follow-up, the results are not compelling when compared to the control group over the same time period.

Conclusions: The results did not identify a positive effect that would support the use of the CDSMP with individual’s post-mild stroke; however, the generalizability of these results is limited secondary to several limitations in this exploratory study.  相似文献

Background: Physical activity and health-related behaviors are important in primary prevention of stroke and are also recommended for secondary prevention. Gender differences in physical activity and health-related behaviors have been reported in various populations and diseased states but data is lacking on stroke survivors.

Objectives: To assess gender disparities in physical activity in stroke patients and to investigate possible reasons for such disparities.

Methods: This is a cross-sectional study using nationwide data from the 5th Korean National Health and Nutrition Examination Survey (2010–2012). A total of 9539 participants (stroke (n = 170), non-stroke (n = 9369)) between the ages of 40–80, with no problems walking were included. Physical activity, smoking, and alcohol drinking of stroke survivors were assessed by gender and compared with non-stroke groups. Multiple logistic regression was used to estimate the odds ratios (ORs) for insufficient physical activity and possible explanatory variables for gender differences.

Results: Women showed higher prevalence of insufficient physical activity after adjusting for age (OR = 7.32, 95% CI: 1.89–28.32) compared to men. Medical conditions such as depression and comorbidities failed to explain the low physical activity in women with stroke but adding socioeconomic factors to the model nullified the gender difference in physical activity.

Conclusion: In order to reduce noted gender disparities in physical activity following stroke, more focused effort to increase physical activity in women, especially with lower socioeconomic status, has to be considered.  相似文献

Background: Caregiver depression and burden have a detrimental effect on stroke survivors’ rehabilitation and are contributors to stroke survivors’ hospital readmission and institutionalization. The stroke caregiving trajectory is unique compared to other illnesses, and the effect of length of caregiving on stroke caregiver outcomes is poorly understood. Interventions can improve caregiver outcomes, but the optimal timing of these interventions is unclear.

Objectives: We sought to determine the relationship between: (1) length of caregiving and stroke caregiver depressive symptoms and burden, and (2) length of caregiving and amount of change in depressive symptoms and burden following the Resources and Education for Stroke Caregivers’ Understanding and Empowerment (RESCUE) intervention – an online and telephone problem-solving, education, and support intervention.

Methods: We analyzed retrospective data collected from 72 stroke caregivers who participated in the RESCUE intervention. Outcomes were caregiver depressive symptoms and burden. Data were analyzed using mixed-effects regression analysis.

Results: Baseline depressive symptoms and burden were both negatively related to length of caregiving (p < 0.05). We found significant improvement in caregiver depressive symptoms and burden following an intervention. The interaction between changes in outcomes and length of caregiving was not significant for either depressive symptoms (p = 0.26) or burden (p = 0.10).

Conclusions: This study contributes to the understanding of the relationship between length of caregiving and depression, burden, and intervention outcomes. Clinicians should recognize that the stroke caregiving trajectory can be nonlinear. Routine and repeated clinical assessment of caregiver well-being is needed, along with implementation of interventions when necessary, regardless of how much time has passed since the stroke.  相似文献
