Dynamic assessment of visual neglect: The Mobility Assessment Course as a diagnostic tool

Introduction: Visual neglect is a frequent disorder following stroke and is often diagnosed by neuropsychological assessment. However, paper-and-pencil tasks have low predictive value as they lack sensitivity to capture neglect in complex, dynamic situations, such as activities of daily living. Aims of the current study were to assess the feasibility of the Mobility Assessment Course (MAC), a visual search multitask, to assess neglect, and its relation with existing neglect tasks. Method: Stroke patients admitted for inpatient rehabilitation and healthy controls were tested with the MAC in different corridors. Participants had to move through a corridor, finding and reporting 24 targets attached to the walls. In addition, the shape cancellation, line bisection, and Catherine Bergego Scale (CBS) were used in order to compare the MAC with existing diagnostic tools for neglect. Results: Administering the MAC was feasible, as 112 of 113 patients completed the MAC with a median duration of 4.09 min. Depending on the corridor where the assessment took place, in 88.5–93.3% of assessments all targets were visible. The number of omissions (total and contralesional) and the asymmetry score (contralesional–ipsilesional omissions) on the MAC as well as collisions and corrections, were higher for patients with neglect than for those without neglect. Depending on the neglect task used, 4.0–18.6% of patients without neglect on neuropsychological tasks or the CBS showed neglect on the MAC. Vice versa, 17.2–29.3% of patients who showed neglect at neuropsychological assessment or the CBS did not do so on the MAC. Finally, a moderate to strong positive relation was seen between neglect at neuropsychological assessment, the CBS, and the MAC. Conclusions: The MAC is an ecological task in which both quantitative and qualitative data on neglect can be collected. In order to assess the presence of neglect and neglect severity in a dynamic way, the MAC could be administered in conjunction with neuropsychological assessment

Measures used to assess impact of providing care among informal caregivers of persons with stroke, spinal cord injury, or amputation:a systematic review

Purpose: (1) To identify measures used to evaluate the impact of caregiving among caregivers of persons with stroke, spinal cord injury, and amputation; and (2) to systematically evaluate their clinimetric properties reported in validation studies. Materials and methods: Two separate systematic reviews (Embase, PsycINFO, CINAHL, Pubmed/Medline) were conducted. COSMIN guidelines were used to assess clinimetric properties and methodological quality of studies. Results: (1) 154 studies published between 2008 and May 2019 were included, in which 48 measures were used, mostly describing negative impact. Thirty measures were used only once and not further described. (2) In general, structural validity, internal consistency, and hypothesis testing were often investigated. Reliability, cross-cultural and criterion validity to a lesser extent, and scale development and content validity were rarely described. Tests of measurement error and responsiveness were exceptional. Most supporting evidence was found for the Zarit Burden Interview Short Form, Caregiver Burden Scale and Positive Aspects of Caregiving Questionnaire. Conclusions: There is a wide variety of impact of caregiving measures. The present study provided a detailed overview of what is known about clinimetric characteristics of 18 different measures repeatedly used in research. The overview provides clinicians a guidance of appropriate measure selection. PROSPERO registration: CRD4201809479

What Does It Take to Search Organized? The Cognitive Correlates of Search Organization During Cancellation After Stroke

AbstractObjectives: Stroke could lead to deficits in organization of visual search. Cancellation tests are frequently used in standard neuropsychological assessment and appear suitable to measure search organization. The current aim was to evaluate which cognitive functions are associated with cancellation organization measures after stroke. Methods: Stroke patients admitted to inpatient rehabilitation were included in this retrospective study. We performed exploratory factor analyses to explore cognitive domains. A digital shape cancellation test (SC) was administered, and measures of search organization (intersections rate and best r) were computed. The following cognitive functions were measured by neuropsychological testing: neglect (SC, line bisection; LB, Catherine Bergego Scale; CBS, and Balloons Test), visuospatial perception and construction (Rey Complex Figure Test, RCFT), psychomotor speed (Trail Making Test; TMT-A), executive functioning/working memory (TMT-B), spatial planning (Tower Test), rule learning (Brixton Test), short-term auditory memory (Digit Span Forward; DSF), and verbal working memory (Digit Span Backward; DSB). Results: In total, 439 stroke patients were included in our analyses. Four clusters were separated: “Executive functioning” (TMT-A, TMT-B, Brixton Test, and Tower Test), “Verbal memory” (DSF and DSB), “Search organization” (intersections rate and best r), and “Neglect” (CBS, RCFT copy, Balloons Test, SC, and LB). Conclusions: Search organization during cancellation, as measured with intersections rate and best r, seems a distinct cognitive construct compared to existing cognitive domains that are tested during neuropsychological assessment. Administering cancellation tests and analyzing measures of search organization could provide useful additional insights into the visuospatial processes of stroke patients.

Validity of the Utrecht scale for evaluation of rehabilitation-participation restrictions scale in a hospital-based stroke population 3 months after stroke

Background:The Utrecht Scale for Evaluation of Rehabilitation-Participation Restrictions scale (USER-P-R) is a promising patient-reported outcome measure, but has currently not been validated in a hospital-based stroke population. Objective:To examine psychometric properties of the USER-P-R in a hospital-based stroke population 3 months after stroke onset. Methods:Cross-sectional study including 359 individuals with stroke recruited through 6 Dutch hospitals. The USER-P-R, EuroQol 5-dimensional 5-level questionnaire (EQ-5D-5 L), Patient Reported Outcomes Measurement Information System 10-Question Global Health Short Form (PROMIS-10), modified Rankin Scale (mRS) and two items on perceived decrease in health and activities post-stroke were administered in a telephone interview 3 months after stroke. The internal consistency, distribution, floor/ceiling effects, convergent validity and discriminant ability of the USER-P-R were calculated. Results:Of all participants, 96.9% were living at home and 50.9% experienced no or minimal disabilities (mRS 0-1). The USER-P-R showed high internal consistency (alpha = 0.90) and a non-normal left-skewed distribution with a ceiling effect (21.4% maximum scores). A substantial proportion of participants with minimal disabilities (mRS 1) experienced restrictions on USER-P-R items (range 11.9-48.5%). The USER-P-R correlated strongly with the EQ-5D-5 L, PROMIS-10 and mRS. The USER-P-R showed excellent discriminant ability in more severely affected individuals with stroke, whereas its discriminant ability in less affected individuals was moderate. Conclusions:The USER-P-R shows good measurement properties and provides additional patient-reported information, proving its usefulness as an instrument to evaluate participation after 3 months in a hospital-based stroke population

Feasibility and user-experience of virtual reality in neuropsychological assessment following stroke

Virtual Reality (VR) offers the possibility to assess cognitive functioning in a dynamic environment resembling daily life. In this cross-sectional study, we used two user interfaces, namely non-immersive VR by using a computer monitor (CM) and immersive VR by using a head-mounted display (HMD). We investigated (1) potential differences in feasibility, user-experience, and a potential preference for one user interface over another between stroke patients and healthy controls; (2) potential differences in feasibility, user-experience, and preference between patients referred for inpatient rehabilitation care and patients referred for outpatient rehabilitation care; and (3) potential demographic and clinical characteristics that were related to patients' preference for one user interface over another. Stroke patients (n = 88) and healthy controls (n = 66) performed a VR-task with a CM and HMD. Both user interfaces were feasible to use, irrespective of clinical referral (in- or outpatient rehabilitation care). Patients reported an enhanced feeling of engagement, transportation, flow, and presence, but more negative side effects when tested with a HMD, compared to a CM. The majority of stroke patients had no preference for one user interface over the other, yet younger patients tended to prefer a HMD. VR seems highly feasible in stroke patients

The longitudinal association between movement behavior patterns and the course of participation up to one year after stroke

Purpose: (1) To investigate the differences in the course of participation up to one year after stroke between distinct movement behavior patterns identified directly after discharge to the home setting, and (2) to investigate the longitudinal association between the development of movement behavior patterns over time and participation after stroke.Materials and methods: 200 individuals with a first-ever stroke were assessed directly after discharge to the home setting, at six months and at one year. The Participation domain of the Stroke Impact Scale 3.0 was used to measure participation. Movement behavior was objectified using accelerometry for 14 days. Participants were categorized into three distinct movement behavior patterns: sedentary exercisers, sedentary movers and sedentary prolongers. Generalized estimating equations (GEE) were performed.Results: People who were classified as sedentary prolongers directly after discharge was associated with a worse course of participation up to one year after stroke. The development of sedentary prolongers over time was also associated with worse participation compared to sedentary exercisers.Conclusions: The course of participation after stroke differs across distinct movement behavior patterns after discharge to the home setting. Highly sedentary and inactive people with stroke are at risk for restrictions in participation over time.Implications for rehabilitation: The course of participation in people with a first-ever stroke up to one year after discharge to the home setting differed based on three distinct movement behavior patterns, i.e., sedentary exercisers, sedentary movers and sedentary prolongers. Early identification of highly sedentary and inactive people with stroke after discharge to the home setting is important, as sedentary prolongers are at risk for restrictions in participation over time. Supporting people with stroke to adapt and maintain a healthy movement behavior after discharge to the home setting could prevent potential long-term restrictions in participation.</p

Self-Efficacy Predicts Personal and Family Adjustment Among Persons With Spinal Cord Injury or Acquired Brain Injury and Their Significant Others:A Dyadic Approach

Objectives: To investigate whether the combination of self-efficacy levels of individuals with spinal cord injury (SCI) or acquired brain injury (ABI) and their significant others, measured shortly after the start of inpatient rehabilitation, predict their personal and family adjustment 6 months after inpatient discharge. Design: Prospective longitudinal study. Setting: Twelve Dutch rehabilitation centers. Participants: Volunteer sample consisting of dyads (N=157) of adults with SCI or ABI who were admitted to inpatient rehabilitation and their adult significant others. Interventions: Not applicable. Main Outcome Measures: Self-efficacy (General Competence Scale) and personal and family adjustment (Hospital Anxiety and Depression Scale and McMaster Family Assessment Device General Functioning). Results: In 20 dyads, both individuals with SCI or ABI and their significant others showed low self-efficacy at baseline. In 67 dyads, both showed high self-efficacy. In the low-self-efficacy dyads, 61% of the individuals with SCI or ABI and 50% of the significant others showed symptoms of anxiety 6 months after discharge, vs 23% and 30%, respectively, in the high-self-efficacy dyads. In the low-self-efficacy dyads, 56% of individuals with SCI or ABI and 50% of the significant others reported symptoms of depression, vs 20% and 27%, respectively, in the high-self-efficacy dyads. Problematic family functioning was reported by 53% of the individuals with SCI or ABI and 42% of the significant others in the low-self-efficacy dyads, vs 4% and 12%, respectively, in the high-self-efficacy dyads. Multivariate analysis of variance analyses showed that the combination of levels of self-efficacy of individuals with SCI or ABI and their significant others at the start of inpatient rehabilitation predict personal (V=0.12; F-6,F-302=2.8; P=.010) and family adjustment (V=0.19; F-6,F-252=4.3; P Conclusions: Low-self-efficacy dyads appear to be more at risk for personal and family adjustment problems after discharge. Screening for self-efficacy may help healthcare professionals to identify and support families at risk for long-term adjustment problems. (C) 2020 by the American Congress of Rehabilitation Medicine.

Effects of family group conferences among high-risk patients of chronic disability and their significant others:study protocol for a multicentre controlled trial

INTRODUCTION: Many patients and family members experience a large gap between the protected environment during inpatient medical rehabilitation and life in the community after discharge. They feel insufficiently prepared to cope with the consequences of their disability in daily life. This study protocol describes the design measuring the effectiveness and implementation of family group conferences on the empowerment of patients with a high risk of chronic disability and their significant others. METHODS AND ANALYSIS: A multicentre controlled trial will be carried out in 12 rehabilitation centres in the Netherlands. A total of 328 clinically admitted patients will participate (≥18 years, diagnosed with acquired brain injury, spinal cord injury or leg amputation), and their significant others will be included. During three family group conferences, supported by the social worker, the patient, significant other and their social network will be stimulated in collaboration, to set up participation goals, determine the needed help and make a concrete action plan. Self-reported questionnaires will be collected at baseline, clinical discharge, and 3 months and 6 months following clinical discharge. Empowerment as the primary outcome is operationalised as self-efficacy and participation. Secondary outcome measures are psychological (eg, coping, neuroticism) and environmental (eg, family functioning, social support) factors. This is the first controlled trial evaluating the effectiveness of family group conferences in rehabilitation medicine among adult patients and their significant others, providing us with knowledge in improving rehabilitation care. ETHICS AND DISSEMINATION: This study has been approved by the Medical Ethics Committee of the University Medical Center Utrecht (number 15-617/C). The results will be published in peer-reviewed journals and presented in local, national and international conferences. TRIAL REGISTRATION NUMBER: NTR5742; Pre-results

Fatigue is Associated with Reduced Participation and Health-related Quality of Life Five Years After Perimesencephalic Subarachnoid Haemorrhage:A Multicentre Cross-sectional Study

OBJECTIVE: To determine whether fatigue is associated with participation and health-related quality of life 5 years after perimesencephalic subarachnoid haemorrhage. DESIGN: Multicentre cross-sectional study. SUBJECTS: Forty-six patients with perimesencephalic subarachnoid haemorrhage. METHODS: Fatigue was assessed with the Fatigue Severity Scale, participation (frequency, restrictions, satisfaction) with the Utrecht Scale for Evaluation of Rehabilitation-Participation, health-related quality of life with the Stroke-Specific Quality of Life Scale-12, symptoms of depression and anxiety with the Hospital Anxiety and Depression Scale, and coping with the Coping Inventory for Stressful Situations. RESULTS: A total of 46 patients were included (63% men, mean age 50.4 ± 9.4 years), with a mean time of 4.7 ± 1.6 years after perimesencephalic subarachnoid haemorrhage onset. Fatigued patients (33%) had worse participation (p < 0.01) and health-related quality of life (p < 0.001) than non-fatigued patients, and more often had hypertension, depression, anxiety and emotion-oriented coping (p < 0.05). Fatigue severity was inversely and independently (p < 0.005) associated with participation frequency (B = –3.62), satisfaction (B = –4.54), having restrictions (odds ratio = 2.48, 95% confidence interval 1.079–5.685), and health-related quality of life (B = –0.19), adjusted for depression, anxiety, and/or hypertension. CONCLUSION: Five years after perimesencephalic subarachnoid haemorrhage, one-third of patients still reported fatigue, which was associated with worse participation and health-related quality of life. Future studies should examine whether these patients may benefit from rehabilitation aimed at fatigue. LAY ABSTRACT A subarachnoid haemorrhage (SAH) is a subtype of stroke. Of all patients with SAH, approximately 10% are diagnosed with non-aneurysmal perimesencephalic subarachnoid haemorrhage (PM-SAH). PM-SAH is generally considered a benign form of SAH; however we have previously found that one-third of patients with PM-SAH are still fatigued 5 years after PM-SAH. Fatigue may be related to reduced participation and health-related quality of life, both of which are considered important rehabilitation outcomes. Therefore, this study examined whether fatigue is associated with participation and health-related quality of life after PM-SAH. The results showed that, 5 years after PM-SAH, fatigued patients had worse participation and quality of life than non-fatigued patients. In addition, more severe fatigue was associated with worse participation, regarding frequency, satisfaction and restrictions, and with worse health-related quality of life. Further studies are necessary to determine whether patients with PM-SAH may benefit from rehabilitation aimed at fatigue

Prediction of Cognitive Recovery after Stroke:The Value of Diffusion-Weighted Imaging–Based Measures of Brain Connectivity

Background and Purpose: Prediction of long-term recovery of a poststroke cognitive disorder (PSCD) is currently inaccurate. We assessed whether diffusion-weighted imaging (DWI)–based measures of brain connectivity predict cognitive recovery 1 year after stroke in patients with PSCD in addition to conventional clinical, neuropsychological, and imaging variables. Methods: This prospective monocenter cohort study included 217 consecutive patients with a clinical diagnosis of ischemic stroke, aged ≥50 years, and Montreal Cognitive Assessment score below 26 during hospitalization. Five weeks after stroke, patients underwent DWI magnetic resonance imaging. Neuropsychological assessment was performed 5 weeks and 1 year after stroke and was used to classify PSCD as absent, modest, or marked. Cognitive recovery was operationalized as a shift to a better PSCD category over time. We evaluated 4 DWI-based measures of brain connectivity: global network efficiency and mean connectivity strength, both weighted for mean diffusivity and fractional anisotropy. Conventional predictors were age, sex, level of education, clinical stroke characteristics, neuropsychological variables, and magnetic resonance imaging findings (eg, infarct size). DWI-based measures of brain connectivity were added to a multivariable model to assess additive predictive value. Results: Of 135 patients (mean age, 71 years; 95 men [70%]) with PSCD 5 weeks after ischemic stroke, 41 (30%) showed cognitive recovery. Three of 4 brain connectivity measures met the predefined threshold of P<0.1 in univariable regression analysis. There was no added value of these measures to a multivariable model that included level of education and infarct size as significant predictors of cognitive recovery. Conclusions: Current DWI-based measures of brain connectivity appear to predict recovery of PSCD but at present have no added value over conventional predictors
