Abstract
BACKGROUND: Disorders of higher visual processing often impact patients with acquired brain injury. Even with treatment, these vision conditions can cause chronic challenges for patients. Understanding these conditions and their management can help improve functional independence and quality of life. OBJECTIVES: To discuss the various disorders of higher visual processing that result from acquired brain injury. Discussion to include classification, evaluation, and treatment techniques available to clinicians. METHODS: Peer reviewed journal articles were searched, primarily through PubMed. Articles spanning several decades were included in the review for historical context of these conditions, however an emphasis was placed on more recent publications for purposes of a discussion regarding clinical management of these conditions. RESULTS: Peer-reviewed articles and clinical trials from across several disciplines were included to frame a discussion of this varied group of conditions. CONCLUSION: Visual processing disorders have debilitating impacts on both the rehabilitation process as well as functional independence. Varied approaches are utilized in the treatment of these conditions with limited success. Understanding the benefits and limitations of both restorative and compensatory treatments will better help clinicians manage patients with these conditions.

Abstract
BACKGROUND The World Health Organization has developed the International Classification of Functions, Disabilities, and Health (ICF) model providing a theoretical basis for physical therapy diagnosis and interventions related to health conditions. However, the multiple relationship between body structure/function and activity domain variables is unknown on the cognition, spasticity, trunk and lower extremity recovery of the sensorimotor function and activity. OBJECTIVE Our study aimed to determine the relationship between body structure/functions and body activity domain variables in adults with stroke. METHODS A total of 218 hemiplegic survivors (102 females, mean age 64.98±13.53) were recruited from the Chungdam Hospital Center for our retrospective study. We used Mini-Mental State Examination (MMSE), Fugl-Meyer Assessment for lower extremity (FMA-LE), Modified Ashworth Scale (MAS), Berg Balance Scale (BBS), Modified Barthel Index (MBI), and Trunk Impairment Scale (TIS) as clinical outcome measures. The Pearson correlation coefficient was used to determine the multiple relationships among the variables at P < 0.05. RESULTS The correlations between body structure/function domain (MMSE, FMA-LE, MAS) and activity domain variables (BBS, MBI, and TIS) were significant, rending from pre -intervention r = -0.216 to 0.766 and post-intervention r = -0.213 to 0.776, P < 0.05, except for MMSE and MAS. CONCLUSIONS Establishing a significant difference between body structure/functions and activity domain variables in our research implies important multiple relationships between cognitive function, lower extremity function, lower extremity spasticity, and balance, and performance of ADL and trunk control coordination after stroke.

Abstract
BACKGROUND People with spatial neglect after stroke or other brain injury have difficulty attending to one side of space. Various rehabilitation interventions have been used, but evidence of their benefit is unclear. OBJECTIVES The main objective was to determine the effects of non-pharmacological interventions for people with spatial neglect after stroke and other adult-acquired non-progressive brain injury. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (last searched October 2020), the Cochrane Central Register of Controlled Trials (CENTRAL; last searched October 2020), MEDLINE (1966 to October 2020), Embase (1980 to October 2020), the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1983 to October 2020), and PsycINFO (1974 to October 2020). We also searched ongoing trials registers and screened reference lists. SELECTION CRITERIA We included randomised controlled trials (RCTs) of any non-pharmacological intervention specifically aimed at spatial neglect. We excluded studies of general rehabilitation and studies with mixed participant groups, unless separate neglect data were available. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Review authors categorised the interventions into eight broad types deemed to be applicable to clinical practice through iterative discussion: visual interventions, prism adaptation, body awareness interventions, mental function interventions, movement interventions, non-invasive brain stimulation, electrical stimulation, and acupuncture. We assessed the quality of evidence for each outcome using the GRADE approach. MAIN RESULTS We included 65 RCTs with 1951 participants, all of which included people with spatial neglect following stroke. Most studies measured outcomes using standardised neglect assessments. Fifty-one studies measured effects on ADL immediately after completion of the intervention period; only 16 reported persisting effects on ADL (our primary outcome). One study (30 participants) reported discharge destination, and one (24 participants) reported depression. No studies reported falls, balance, or quality of life. Only two studies were judged to be entirely at low risk of bias, and all were small, with fewer than 50 participants per group. We found no definitive (phase 3) clinical trials. None of the studies reported any patient or public involvement. Visual interventions versus any control: evidence is very uncertain about the effects of visual interventions for spatial neglect based on measures of persisting functional ability in ADL (2 studies, 55 participants) (standardised mean difference (SMD) -0.04, 95% confidence interval (CI) -0.57 to 0.49); measures of immediate functional ability in ADL; persisting standardised neglect assessments; and immediate neglect assessments. Prism adaptation versus any control: evidence is very uncertain about the effects of prism adaptation for spatial neglect based on measures of persisting functional ability in ADL (2 studies, 39 participants) (SMD -0.29, 95% CI -0.93 to 0.35); measures of immediate functional ability in ADL; persisting standardised neglect assessments; and immediate neglect assessments. Body awareness interventions versus any control: evidence is very uncertain about the effects of body awareness interventions for spatial neglect based on measures of persisting functional ability in ADL (5 studies, 125 participants) (SMD 0.61, 95% CI 0.24 to 0.97); measures of immediate functional ability in ADL; persisting standardised neglect assessments; immediate neglect assessments; and adverse events. Mental function interventions versus any control: we found no trials of mental function interventions for spatial neglect reporting on measures of persisting functional ability in ADL. Evidence is very uncertain about the effects of mental function interventions on spatial neglect based on measures of immediate functional ability in ADL and immediate neglect assessments. Movement interventions versus any control: we found no trials of movement interventions for spatial neglect reporting on measures of persisting functional ability in ADL. Evidence is very uncertain about the effects of body awareness interventions on spatial neglect based on measures of immediate functional ability in ADL and immediate neglect assessments. Non-invasive brain stimulation (NIBS) versus any control: evidence is very uncertain about the effects of NIBS on spatial neglect based on measures of persisting functional ability in ADL (3 studies, 92 participants) (SMD 0.35, 95% CI -0.08 to 0.77); measures of immediate functional ability in ADL; persisting standardised neglect assessments; immediate neglect assessments; and adverse events. Electrical stimulation versus any control: we found no trials of electrical stimulation for spatial neglect reporting on measures of persisting functional ability in ADL. Evidence is very uncertain about the effects of electrical stimulation on spatial neglect based on immediate neglect assessments. Acupuncture versus any control: we found no trials of acupuncture for spatial neglect reporting on measures of persisting functional ability in ADL. Evidence is very uncertain about the effects of acupuncture on spatial neglect based on measures of immediate functional ability in ADL and immediate neglect assessments. AUTHORS' CONCLUSIONS The effectiveness of non-pharmacological interventions for spatial neglect in improving functional ability in ADL and increasing independence remains unproven. Many strategies have been proposed to aid rehabilitation of spatial neglect, but none has yet been sufficiently researched through high-quality fully powered randomised trials to establish potential or adverse effects. As a consequence, no rehabilitation approach can be supported or refuted based on current evidence from RCTs. As recommended by a number of national clinical guidelines, clinicians should continue to provide rehabilitation for neglect that enables people to meet their rehabilitation goals. Clinicians and stroke survivors should have the opportunity, and are strongly encouraged, to participate in research. Future studies need to have appropriate high-quality methodological design, delivery, and reporting to enable appraisal and interpretation of results. Future studies also must evaluate outcomes of importance to patients, such as persisting functional ability in ADL. One way to improve the quality of research is to involve people with experience with the condition in designing and running trials.

Abstract
AIM To provide a systematic overview of interventions for stroke related visual impairments. METHOD A systematic review of the literature was conducted including randomized controlled trials, controlled trials, cohort studies, observational studies, systematic reviews, and retrospective medical note reviews. All languages were included and translation obtained. This review covers adult participants (aged 18 years or over) diagnosed with a visual impairment as a direct cause of a stroke. Studies which included mixed populations were included if over 50% of the participants had a diagnosis of stroke and were discussed separately. We searched scholarly online resources and hand searched articles and registers of published, unpublished, and ongoing trials. Search terms included a variety of MESH terms and alternatives in relation to stroke and visual conditions. Article selection was performed by two authors independently. Data were extracted by one author and verified by a second. The quality of the evidence and risk of bias was assessed using appropriate tools dependant on the type of article. RESULTS Forty-nine articles (4142 subjects) were included in the review, including an overview of four Cochrane systematic reviews. Interventions appraised included those for visual field loss, ocular motility deficits, reduced central vision, and visual perceptual deficits. CONCLUSION Further high quality randomized controlled trials are required to determine the effectiveness of interventions for treating post-stroke visual impairments. For interventions which are used in practice but do not yet have an evidence base in the literature, it is imperative that these treatments be addressed and evaluated in future studies.

Abstract
BACKGROUND In the last decades, several rehabilitation methods have been developed to improve spatial neglect. These can be classified according to their theoretical basis: (i) enhance awareness of neglect behaviour through a top-down mechanism; (ii) low-level bottom-up sensory stimulation; (iii) modulation of inhibitory processes; (iv) increase arousal. OBJECTIVE The purpose of this study was to provide an overview of the evidence on the effectiveness of rehabilitation procedures for unilateral neglect. METHOD A systematic search was performed to look for all randomised controlled trials aimed at reducing left spatial neglect that included a functional assessment. In addition, recent review papers and meta-analyses were analysed. RESULTS Thirty-seven randomized controlled trials were found (12 bottom-up; 12 top-down; 1 interhemispheric competition; 12 combination of approaches) that included 1027 patients with neglect. Although there are some encouraging results, overall, the level of evidence remains low. Poor methodological quality and small sample sizes are major limitations in many published trials. CONCLUSION There is a need for well-conducted, large-scale randomised controlled trials that incorporate blinded assessments, evaluation of the generalization to activities of daily living and long-term follow-up.

Abstract
BACKGROUND Although cognitive impairments are common following stroke, there is considerable uncertainty about the types of interventions that can reduce activity restrictions and improve quality of life. Indeed, a recent project to identify priorities for research into life after stroke determined that the top priority for patients, carers and health professionals was how to improve cognitive impairments. OBJECTIVE To provide an overview of the evidence for the effectiveness of cognitive rehabilitation for patients with stroke and to determine the main gaps in the current evidence base. METHODS Evidence was synthesised for the six Cochrane reviews relating to rehabilitation for post-stroke cognitive impairment and any subsequently published randomized controlled trials to February 2012. RESULTS Data arising from 44 trials involving over 1500 patients was identified. Though there was support for the effectiveness of cognitive rehabilitation for some cognitive impairments, significant gaps were found in the current evidence base. All of the Cochrane reviews identified major limitations within the evidence they identified. CONCLUSIONS There is currently insufficient research evidence, or evidence of insufficient quality, to support clear recommendations for clinical practice. Recommendations are made as to the research required to strengthen the evidence base, and so facilitate the delivery of effective interventions to individuals with cognitive impairment after stroke.

Abstract
BACKGROUND Unilateral spatial neglect causes difficulty attending to one side of space. Various rehabilitation interventions have been used but evidence of their benefit is lacking. OBJECTIVES To assess whether cognitive rehabilitation improves functional independence, neglect (as measured using standardised assessments), destination on discharge, falls, balance, depression/anxiety and quality of life in stroke patients with neglect measured immediately post-intervention and at longer-term follow-up; and to determine which types of interventions are effective and whether cognitive rehabilitation is more effective than standard care or an attention control. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (last searched June 2012), MEDLINE (1966 to June 2011), EMBASE (1980 to June 2011), CINAHL (1983 to June 2011), PsycINFO (1974 to June 2011), UK National Research Register (June 2011). We handsearched relevant journals (up to 1998), screened reference lists, and tracked citations using SCISEARCH. SELECTION CRITERIA We included randomised controlled trials (RCTs) of cognitive rehabilitation specifically aimed at spatial neglect. We excluded studies of general stroke rehabilitation and studies with mixed participant groups, unless more than 75% of their sample were stroke patients or separate stroke data were available. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, extracted data, and assessed study quality. For subgroup analyses, review authors independently categorised the approach underlying the cognitive intervention as either 'top-down' (interventions that encourage awareness of the disability and potential compensatory strategies) or 'bottom-up' (interventions directed at the impairment but not requiring awareness or behavioural change, e.g. wearing prisms or patches). MAIN RESULTS We included 23 RCTs with 628 participants (adding 11 new RCTs involving 322 new participants for this update). Only 11 studies were assessed to have adequate allocation concealment, and only four studies to have a low risk of bias in all categories assessed. Most studies measured outcomes using standardised neglect assessments: 15 studies measured effect on activities of daily living (ADL) immediately after the end of the intervention period, but only six reported persisting effects on ADL. One study (30 participants) reported discharge destination and one study (eight participants) reported the number of falls.Eighteen of the 23 included RCTs compared cognitive rehabilitation with any control intervention (placebo, attention or no treatment). Meta-analyses demonstrated no statistically significant effect of cognitive rehabilitation, compared with control, for persisting effects on either ADL (five studies, 143 participants) or standardised neglect assessments (eight studies, 172 participants), or for immediate effects on ADL (10 studies, 343 participants). In contrast, we found a statistically significant effect in favour of cognitive rehabilitation compared with control, for immediate effects on standardised neglect assessments (16 studies, 437 participants, standardised mean difference (SMD) 0.35, 95% confidence interval (CI) 0.09 to 0.62). However, sensitivity analyses including only studies of high methodological quality removed evidence of a significant effect of cognitive rehabilitation.Additionally, five of the 23 included RCTs compared one cognitive rehabilitation intervention with another. These included three studies comparing a visual scanning intervention with another cognitive rehabilitation intervention, and two studies (three comparison groups) comparing a visual scanning intervention plus another cognitive rehabilitation intervention with a visual scanning intervention alone. Only two small studies reported a measure of functional disability and there was considerable heterogeneity within these subgroups (I² > 40%) when we pooled standardised neglect assessment data, limiting the ability to draw generalised conclusions.Subgroup analyses exploring the effect of having an attention control demonstrated some evidence of a statistically significant difference between those comparing rehabilitation with attention control and those with another control or no treatment group, for immediate effects on standardised neglect assessments (test for subgroup differences, P = 0.04). AUTHORS' CONCLUSIONS The effectiveness of cognitive rehabilitation interventions for reducing the disabling effects of neglect and increasing independence remains unproven. As a consequence, no rehabilitation approach can be supported or refuted based on current evidence from RCTs. However, there is some very limited evidence that cognitive rehabilitation may have an immediate beneficial effect on tests of neglect. This emerging evidence justifies further clinical trials of cognitive rehabilitation for neglect. However, future studies need to have appropriate high quality methodological design and reporting, to examine persisting effects of treatment and to include an attention control comparator.

Abstract
We reviewed all randomised trials on cognitive rehabilitation in order to determine the effective elements in terms of patients' and treatment characteristics, treatment goals and outcome. A total of 95 random controlled trials were included from January 1980 until August 2010 studying 4068 patients in total. Most studies had been conducted on language (n = 25), visuospatial functioning (n = 24), and memory (n = 14). Stroke patients were the commonest subjects (57%; overall mean age = 52.2, SD = 15.0 years). Of the interventions 39% were offered more than 12 months after onset and 23% were offered within two months of onset. The mean (SD) number of hours of treatment actually delivered was 4.1 (3.6) per week; treatment was mostly offered individually. No papers gave specific information on the expertise or competences of the staff involved. With 95 RCTs there is a large body of evidence to support the efficacy of cognitive rehabilitation, and the current study can serve as a database for clinicians and researchers. But most studies have given little information about the actual content of the treatment which makes it difficult to use the studies when making treatment decisions in daily clinical practice. We suggest developing an international checklist to make standardised description of non-pharmacological complex interventions possible.

Abstract
Abstract
I reviewed articles published in the American Journal of Occupational Therapy (AJOT) in 2009 and 2010 to assess (1) whether research was published in the practice area of rehabilitation, disability, and participation and (2) the evidence being produced in an underdeveloped subcategory of this practice area: cognitive rehabilitation after stroke. The review revealed one intervention effectiveness study that addressed cognitive rehabilitation poststroke published in the 2-year period. Further analysis of outside repositories of evidence in this area revealed that although some evidence supports rehabilitation approaches for people with cognitive dysfunction after a stroke, little research has been devoted to this practice area. The poststroke cognitive intervention approaches in use have been shown to have little or no effect on improving everyday life activity. Occupational therapy has a key research and practice role with the poststroke population, and occupational therapists should be at the forefront in developing the science to support the effectiveness of their services.

Abstract
Unilateral neglect is a multimodal neuropsychological disorder that has puzzled scientists for a long time. Many interventions have been developed, but only a handful has proven to be effective. This review examines whether applying different therapeutic techniques in combination will increase therapeutic benefits. Studies were reviewed where therapies are applied sequentially or in combination with other techniques. The results indicate that combining different interventions leads to increased general improvement compared with other noncombined designs, even when the number of treatment sessions is not constant. Practical and theoretical aspects of different treatments are discussed. The combined approach to treatment may have direct relevance to disorders other than neglect. This report introduces a new classification scheme for different interventions with the aim of facilitating more focused therapy. Finally, suggestions are made as to what the focus of future studies of neglect therapy should be and how therapeutic benefits might be maximized.

Abstract
The aim of this study is to assess the reported quality of randomized controlled trials (RCTs) on the effectiveness of neglect rehabilitation using a standardized scale. A search of seven electronic databases was carried out. Selected articles were scored using the PEDro scale and classified as high or low quality study both with the original cut off of 6 and a modified cut off of 5. A linear regression analysis between year of publication and quality rate was used to test whether the quality of the studies improved with time. A total of 18 RCTs were selected. Six articles (33.3%) and 10 articles (55.56%) were classified as having high quality when the original cut off or the modified cut off of the PEDro scale were used, respectively. Analysis shows no time-related changes in PEDro scores. The results show that reported quality is moderate for RCTs in neglect rehabilitation.

Abstract
Visual deficits after cerebral injury are common. The variability in the types of injury sustained as well as their impact on function in the environment have produced multiple approaches at corrective intervention. To assess the effectiveness of these vision interventions, an extensive literature search was completed. The analysis of this review revealed some success with visual neglect disorders, but not enough evidence to comment definitively on interventions for hemianopsia, quadrantonopsia, diplopia, or convergence insufficiency. A lack of follow-up also limited efforts to assess the durability of documented gains. Additional research is necessary to clarify, quantify, and measure treatment outcomes for acquired visual dysfunction as well as to link laboratory testing to improvement in actual functioning for individuals in their environment.

Abstract
BACKGROUND Unilateral spatial neglect causes difficulty attending to one side of space. Various rehabilitation strategies have been used but evidence of their benefit is lacking. OBJECTIVES To determine the persisting effects of cognitive rehabilitation specifically aimed at spatial neglect following stroke, as measured on impairment and disability level outcome assessments and on destination on discharge from hospital. SEARCH STRATEGY We searched the Cochrane Stroke Group Trials Register (last searched 4 July 2005), MEDLINE (1966 to July 2005), EMBASE (1980 to July 2005), CINAHL (1983 to July 2005), PsycINFO (1974 to July 2005), UK National Research Register (July 2005). We handsearched relevant journals, screened reference lists, and tracked citations using SCISEARCH. SELECTION CRITERIA We included randomised controlled trials of cognitive rehabilitation specifically aimed at spatial neglect. We excluded studies of general stroke rehabilitation and studies with mixed patient groups, unless more than 75% of their sample were stroke patients or separate stroke data were available. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, extracted data, and assessed trial quality. MAIN RESULTS We included 12 RCTs with 306 participants. Only four had adequate allocation concealment, that is a low risk of selection bias. A large number of outcome measures were reported. Only six studies measured disability and two investigated whether the effects persisted. The overall effect (standardised mean difference) on disability had a wide confidence interval that included zero and was not statistically significant. For discharge destination there were clinically significant effects but in both directions and the confidence interval of the odds ratio included one. In contrast, cognitive rehabilitation did improve performance on some, but not all, standardised neglect tests. The number of cancellation errors made was reduced and the ability to find the midpoint of a line improved immediately and persisted at follow up. These effects appeared likely to generalise from the samples studied to the target population, but were based on a small number of studies. AUTHORS' CONCLUSIONS Several types of neglect specific approaches are now described but there is insufficient evidence to support or refute their effectiveness at reducing disability and improving independence. They can alter test performance and warrant further investigation in high quality randomised controlled trials. As we did not review whether patients with neglect benefit from rehabilitation input in general, such patients should continue to receive general stroke rehabilitation services.
