Abstract
BACKGROUND Depression is an important morbidity associated with stroke that impacts on recovery, yet is often undetected or inadequately treated. OBJECTIVES To evaluate the benefits and harms of pharmacological intervention, non-invasive brain stimulation, psychological therapy, or combinations of these to treat depression after stroke. SEARCH METHODS This is a living systematic review. We search for new evidence every two months and update the review when we identify relevant new evidence. Please refer to the Cochrane Database of Systematic Reviews for the current status of this review. We searched the Specialised Registers of Cochrane Stroke, and Cochrane Depression Anxiety and Neurosis, CENTRAL, MEDLINE, Embase, five other databases, two clinical trials registers, reference lists and conference proceedings (February 2022). We contacted study authors. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing: 1) pharmacological interventions with placebo; 2) non-invasive brain stimulation with sham stimulation or usual care; 3) psychological therapy with usual care or attention control; 4) pharmacological intervention and psychological therapy with pharmacological intervention and usual care or attention control; 5) pharmacological intervention and non-invasive brain stimulation with pharmacological intervention and sham stimulation or usual care; 6) non-invasive brain stimulation and psychological therapy versus sham brain stimulation or usual care and psychological therapy; 7) pharmacological intervention and psychological therapy with placebo and psychological therapy; 8) pharmacological intervention and non-invasive brain stimulation with placebo and non-invasive brain stimulation; and 9) non-invasive brain stimulation and psychological therapy versus non-invasive brain stimulation and usual care or attention control, with the intention of treating depression after stroke. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risk of bias, and extracted data from included studies. We calculated mean difference (MD) or standardised mean difference (SMD) for continuous data, and risk ratio (RR) for dichotomous data, with 95% confidence intervals (CIs). We assessed heterogeneity using the I² statistic and certainty of the evidence according to GRADE. MAIN RESULTS We included 65 trials (72 comparisons) with 5831 participants. Data were available for: 1) 20 comparisons; 2) nine comparisons; 3) 25 comparisons; 4) three comparisons; 5) 14 comparisons; and 6) one comparison. We found no trials for comparisons 7 to 9. Comparison 1: Pharmacological interventions Very low-certainty evidence from eight trials suggests pharmacological interventions decreased the number of people meeting the study criteria for depression (RR 0.70, 95% CI 0.55 to 0.88; P = 0.002; 8 RCTs; 1025 participants) at end of treatment and very low-certainty evidence from six trials suggests that pharmacological interventions decreased the number of people with inadequate response to treatment (RR 0.47, 95% CI 0.32 to 0.70; P = 0.0002; 6 RCTs; 511 participants) compared to placebo. More adverse events related to the central nervous system (CNS) (RR 1.55, 95% CI 1.12 to 2.15; P = 0.008; 5 RCTs; 488 participants; very low-certainty evidence) and gastrointestinal system (RR 1.62, 95% CI 1.19 to 2.19; P = 0.002; 4 RCTs; 473 participants; very low-certainty evidence) were noted in the pharmacological intervention than in the placebo group. Comparison 2: Non-invasive brain stimulation Very low-certainty evidence from two trials show that non-invasive brain stimulation had little to no effect on the number of people meeting the study criteria for depression (RR 0.67, 95% CI 0.39 to 1.14; P = 0.14; 2 RCTs; 130 participants) and the number of people with inadequate response to treatment (RR 0.84, 95% CI 0.52, 1.37; P = 0.49; 2 RCTs; 130 participants) compared to sham stimulation. Non-invasive brain stimulation resulted in no deaths. Comparison 3: Psychological therapy Very low-certainty evidence from six trials suggests that psychological therapy decreased the number of people meeting the study criteria for depression at end of treatment (RR 0.77, 95% CI 0.62 to 0.95; P = 0.01; 521 participants) compared to usual care/attention control. No trials of psychological therapy reported on the outcome inadequate response to treatment. No differences in the number of deaths or adverse events were found in the psychological therapy group compared to the usual care/attention control group. Comparison 4: Pharmacological interventions with psychological therapy No trials of this combination reported on the primary outcomes. Combination therapy resulted in no deaths. Comparison 5: Pharmacological interventions with non-invasive brain stimulation Non-invasive brain stimulation with pharmacological intervention reduced the number of people meeting study criteria for depression at end of treatment (RR 0.77, 95% CI 0.64 to 0.91; P = 0.002; 3 RCTs; 392 participants; low-certainty evidence) but not the number of people with inadequate response to treatment (RR 0.95, 95% CI 0.69 to 1.30; P = 0.75; 3 RCTs; 392 participants; very low-certainty evidence) compared to pharmacological therapy alone. Very low-certainty evidence from five trials suggest no difference in deaths between this combination therapy (RR 1.06, 95% CI 0.27 to 4.16; P = 0.93; 487 participants) compared to pharmacological therapy intervention and sham stimulation or usual care. Comparison 6: Non-invasive brain stimulation with psychological therapy No trials of this combination reported on the primary outcomes. AUTHORS' CONCLUSIONS Very low-certainty evidence suggests that pharmacological, psychological and combination therapies can reduce the prevalence of depression while non-invasive brain stimulation had little to no effect on the prevalence of depression. Pharmacological intervention was associated with adverse events related to the CNS and the gastrointestinal tract. More research is required before recommendations can be made about the routine use of such treatments.

Abstract
BACKGROUND Antidepressants may be useful in the treatment of abnormal crying associated with stroke. This is an update of a Cochrane Review first published in 2004 and last updated in 2019. OBJECTIVES To evaluate the benefits and harms of pharmaceutical treatment in people with emotionalism after stroke. SEARCH METHODS We searched the Cochrane Stroke Group Register, CENTRAL, MEDLINE, Embase, four other databases, and three trials registers (May 2022). SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs comparing psychotropic medication to placebo in people with stroke and emotionalism (also known as emotional lability, pathological crying or laughing, emotional incontinence, involuntary emotional expression disorder, and pseudobulbar affect). DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, assessed risk of bias, extracted data from all included trials, and used GRADE to assess the certainty of the body of evidence. We calculated the mean difference (MD) or standardised mean difference (SMD) for continuous data and the risk ratio (RR) for dichotomous data, with 95% confidence intervals (CIs). We assessed heterogeneity using the I2 statistic. The primary emotionalism measures were the proportion of participants achieving at least a 50% reduction in abnormal emotional behaviour at the end of treatment, improved score on the Center for Neurologic Study - Lability Scale (CNS-LS) or Clinician Interview-Based Impression of Change (CIBIC), or diminished tearfulness. MAIN RESULTS We did not identify any new trials for this update. We included seven trials with a total of 239 participants. Two trials had a cross-over design, but outcome data were not available from the first phase (precross-over) in an appropriate format for inclusion as a parallel randomised controlled trial (RCT). Thus, the results of the review are based on five trials with a total of 213 participants. It is uncertain whether fluoxetine increases the number of people who have a 50% reduction in emotionalism when compared to placebo (risk ratio (RR) 0.26, 95% CI 0.09 to 0.77; P = 0.02; 1 trial, 19 participants) because the certainty of evidence is very low. Sertraline may lead to little to no difference in Center for Neurologic Study - Lability Scale (CNS-LS) scores and Clinician Interview-Based Impression of Change (CIBIC) scores when compared to placebo (RR 0.20, 95% CI 0.03 to 1.50; P = 0.12; 1 trial, 28 participants; low-certainty evidence). Antidepressants probably increase the number of people who experience a reduction in tearfulness (RR 0.32, 95% CI 0.12 to 0.86; P = 0.02; 3 trials, 164 participants; moderate-certainty evidence). No trials were found that evaluated the impact of other pharmaceutical interventions. Only two trial authors systematically recorded and reported adverse events, resulting in limited data on the potential harms of treatment. Six trials reported death as an adverse event and found no difference between the groups (antidepressants versus placebo) in the number of deaths reported (RR 0.59, 95% CI 0.08 to 4.50; P = 0.61; 172 participants; moderate-certainty evidence). This review provides very low- to moderate-certainty evidence that antidepressants may reduce the frequency and severity of emotionalism. The included trials were small and had some degree of bias. AUTHORS' CONCLUSIONS Antidepressants may reduce the frequency and severity of crying or laughing episodes when compared to placebo, based on very low-certainty evidence. Our conclusions must be qualified by several methodological deficiencies in the trials and interpreted with caution despite the effect being very large. The effect does not seem specific to one drug or class of drugs. More reliable data are required before appropriate conclusions can be made about the treatment of post-stroke emotionalism. Future trialists investigating the effect of antidepressants in people with emotionalism after stroke should consider developing and using a standardised method to diagnose emotionalism, determine severity, and assess change over time; provide treatment for a sufficient duration and follow-up to better assess rates of relapse or maintenance; and include careful assessment and complete reporting of adverse events.

Abstract
BACKGROUND Depression is an important consequence of stroke that influences recovery yet often is not detected, or is inadequately treated. This is an update and expansion of a Cochrane Review first published in 2004 and previously updated in 2008. OBJECTIVES The primary objective is to test the hypothesis that pharmacological, psychological therapy, non-invasive brain stimulation, or combinations of these interventions reduce the incidence of diagnosable depression after stroke. Secondary objectives are to test the hypothesis that pharmacological, psychological therapy, non-invasive brain stimulation or combinations of these interventions reduce levels of depressive symptoms and dependency, and improve physical functioning after stroke. We also aim to determine the safety of, and adherence to, the interventions. SEARCH METHODS We searched the Specialised Register of Cochrane Stroke and the Cochrane Depression Anxiety and Neurosis (last searched August 2018). In addition, we searched the following databases; Cochrane Central Register of Controlled Trials, CENTRAL (the Cochrane Library, 2018, Issue 8), MEDLINE (1966 to August 2018), Embase (1980 to August 2018), PsycINFO (1967 to August 2018), CINAHL (1982 to August 2018) and three Web of Science indexes (2002 to August 2018). We also searched reference lists, clinical trial registers (World Health Organization International Clinical Trials Registry Platform (WHO ICTRP); to August 2018 and ClinicalTrials.gov; to August 2018), conference proceedings; we also contacted study authors. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing: 1) pharmacological interventions with placebo; 2) one of various forms of psychological therapy with usual care and/or attention control; 3) one of various forms of non-invasive brain stimulation with sham stimulation or usual care; 4) a pharmacological intervention and one of various forms of psychological therapy with a pharmacological intervention and usual care and/or attention control; 5) non-invasive brain stimulation and pharmacological intervention with a pharmacological intervention and sham stimulation or usual care; 6) pharmacological intervention and one of various forms of psychological therapy with placebo and psychological therapy; 7) pharmacological intervention and non-invasive brain stimulation with placebo plus non-invasive brain stimulation; 8) non-invasive brain stimulation and one of various forms of psychological therapy versus non-invasive brain stimulation plus usual care and/or attention control; and 9) non-invasive brain stimulation and one of various forms of psychological therapy versus sham brain stimulation or usual care plus psychological therapy, with the intention of preventing depression after stroke. DATA COLLECTION AND ANALYSIS Review authors independently selected studies, assessed risk of bias, and extracted data from all included studies. We calculated mean difference (MD) or standardised mean difference (SMD) for continuous data and risk ratio (RR) for dichotomous data with 95% confidence intervals (CIs). We assessed heterogeneity using the I2 statistic and assessed the certainty of evidence using GRADE. MAIN RESULTS We included 19 RCTs (21 interventions), with 1771 participants in the review. Data were available for 12 pharmacological trials (14 interventions) and seven psychological trials. There were no trials of non-invasive brain stimulation compared with sham stimulation or usual care, a combination of pharmacological intervention and one of various forms of psychological therapy with placebo and psychological therapy, or a combination of non-invasive brain stimulation and a pharmacological intervention with a pharmacological intervention and sham stimulation or usual care to prevent depression after stroke. Treatment effects were observed on the primary outcome of meeting the study criteria for depression at the end of treatment: there is very low-certainty evidence from eight trials (nine interventions) that pharmacological interventions decrease the number of people meeting the study criteria for depression (RR 0.50, 95% CI 0.37 to 0.68; 734 participants) compared to placebo. There is very low-certainty evidence from two trials that psychological interventions reduce the proportion of people meeting the study criteria for depression (RR 0.68, 95% CI 0.49 to 0.94, 607 participants) compared to usual care and/or attention control. Eight trials (nine interventions) found no difference in death and other adverse events between pharmacological intervention and placebo groups (RR 1.25, 95% CI 0.32 to 4.91; 496 participants) based on very low-certainty evidence. Five trials found no difference in psychological intervention and usual care and/or attention control groups for death and other adverse events (RR 1.18, 95% CI 0.73 to 1.91; 975 participants) based on very low-certainty evidence. AUTHORS' CONCLUSIONS The available evidence suggests that pharmacological interventions and psychological therapy may prevent depression and improve mood after stroke. However, there is very low certainty in these conclusions because of the very low-certainty evidence. More trials are required before reliable recommendations can be made about the routine use of such treatments after stroke.

BACKGROUND Depression is an important morbidity associated with stroke that impacts on recovery yet often undetected or inadequately treated. This is an update and expansion of a Cochrane Review first published in 2004 and updated in 2008. OBJECTIVES Primary objective • To determine whether pharmacological therapy, non-invasive brain stimulation, psychological therapy, or combinations of these interventions reduce the prevalence of diagnosable depression after stroke Secondary objectives • To determine whether pharmacological therapy, non-invasive brain stimulation, psychological therapy, or combinations of these interventions reduce levels of depressive symptoms, improve physical and neurological function and health-related quality of life, and reduce dependency after stroke • To assess the safety of and adherence to such treatments SEARCH METHODS: We searched the Specialised Registers of Cochrane Stroke and Cochrane Depression Anxiety and Neurosis (last searched August 2018), the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 1), in the Cochrane Library, MEDLINE (1966 to August 2018), Embase (1980 to August 2018), the Cumulative Index to Nursing and Alllied Health Literature (CINAHL) (1982 to August 2018), PsycINFO (1967 to August 2018), and Web of Science (2002 to August 2018). We also searched reference lists, clinical trial registers (World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) to August 2018; ClinicalTrials.gov to August 2018), and conference proceedings, and we contacted study authors. SELECTION CRITERIA Randomised controlled trials comparing (1) pharmacological interventions with placebo; (2) one of various forms of non-invasive brain stimulation with sham stimulation or usual care; (3) one of various forms of psychological therapy with usual care and/or attention control; (4) pharmacological intervention and various forms of psychological therapy with pharmacological intervention and usual care and/or attention control; (5) non-invasive brain stimulation and pharmacological intervention with pharmacological intervention and sham stimulation or usual care; (6) pharmacological intervention and one of various forms of psychological therapy with placebo and psychological therapy; (7) pharmacological intervention and non-invasive brain stimulation with placebo plus non-invasive brain stimulation; (8) non-invasive brain stimulation and one of various forms of psychological therapy versus non-invasive brain stimulation plus usual care and/or attention control; and (9) non-invasive brain stimulation and one of various forms of psychological therapy versus sham brain stimulation or usual care plus psychological therapy, with the intention of treating depression after stroke. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risk of bias, and extracted data from all included studies. We calculated mean difference (MD) or standardised mean difference (SMD) for continuous data, and risk ratio (RR) for dichotomous data, with 95% confidence intervals (CIs). We assessed heterogeneity using the I² statistic and certainty of the evidence according to GRADE. MAIN RESULTS We included 49 trials (56 comparisons) with 3342 participants. Data were available for: (1) pharmacological interventions with placebo (with 20 pharmacological comparisons); (2) one of various forms of non-invasive brain stimulation with sham stimulation or usual care (with eight non-invasive brain stimulation comparisons); (3) one of various forms of psychological therapy with usual care and/or attention control (with 16 psychological therapy comparisons); (4) pharmacological intervention and various forms of psychological therapy with pharmacological intervention and usual care and/or attention control (with two comparisons); and (5) non-invasive brain stimulation and pharmacological intervention with pharmacological intervention and sham stimulation or usual care (with 10 comparisons). We found no trials for the following comparisons: (6) pharmacological intervention and various forms of psychological therapy interventions versus placebo and psychological therapy; (7) pharmacological intervention and non-invasive brain stimulation versus placebo plus non-invasive brain stimulation; (8) non-invasive brain stimulation and one of various forms of psychological therapy versus non-invasive brain stimulation plus usual care and/or attention control; and (9) non-invasive brain stimulation and one of various forms of psychological therapy versus sham brain stimulation or usual care plus psychological therapy. Treatment effects observed: very low-certainty evidence from eight trials suggests that pharmacological interventions decreased the number of people meeting study criteria for depression (RR 0.70, 95% CI 0.55 to 0.88; 1025 participants) at end of treatment, and very low-certainty evidence from six trials suggests that pharmacological interventions decreased the number of people with less than 50% reduction in depression scale scores at end of treatment (RR 0.47, 95% CI 0.32 to 0.69; 511 participants) compared to placebo. No trials of non-invasive brain stimulation reported on meeting study criteria for depression at end of treatment. Only one trial of non-invasive brain stimulation reported on the outcome <50% reduction in depression scale scores; thus, we were unable to perform a meta-analysis for this outcome. Very low-certainty evidence from six trials suggests that psychological therapy decreased the number of people meeting the study criteria for depression at end of treatment (RR 0.77, 95% CI 0.62 to 0.95; 521 participants) compared to usual care/attention control. No trials of combination therapies reported on the number of people meeting the study criteria for depression at end of treatment. Only one trial of combination (non-invasive brain stimulation and pharmacological intervention) therapy reported <50% reduction in depression scale scores at end of treatment. Thus, we were unable to perform a meta-analysis for this outcome. Five trials reported adverse events related to the central nervous system (CNS) and noted significant harm in the pharmacological interventions group (RR 1.55, 95% CI 1.12 to 2.15; 488 participants; very low-certainty evidence). Four trials found significant gastrointestinal adverse events in the pharmacological interventions group (RR 1.62, 95% CI 1.19 to 2.19; 473 participants; very low-certainty evidence) compared to the placebo group. No significant deaths or adverse events were found in the psychological therapy group compared to the usual care/attention control group. Non-invasive brain stimulation interventions and combination therapies resulted in no deaths. AUTHORS' CONCLUSIONS Very low-certainty evidence suggests that pharmacological or psychological therapies can reduce the prevalence of depression. This very low-certainty evidence suggests that pharmacological therapy, psychological therapy, non-invasive brain stimulation, and combined interventions can reduce depressive symptoms. Pharmacological intervention was associated with adverse events related to the CNS and the gastrointestinal tract. More research is required before recommendations can be made about the routine use of such treatments.

Abstract
BACKGROUND Antidepressants may be useful in the treatment of abnormal crying associated with stroke. This is an update of a Cochrane Review first published in 2004 and last updated in 2010. OBJECTIVES To determine whether pharmaceutical treatment reduces the frequency of emotional displays in people with emotionalism after stroke. SEARCH METHODS We searched the trial register of Cochrane Stroke (last searched May 2018). In addition, we searched the Cochrane Central Register of Controlled Trials (CENTRAL; to May 2018), MEDLINE (1966 to 14 May 2018), Embase (1980 to 14 May 2018), CINAHL (1982 to 14 May 2018), PsycINFO (1967 to 14 May 2018), BIOSIS Previews (2002 to 14 May 2018), Web of Science (2002 to 14 May 2018), WHO ICTRP (to 14 May 2018), ClinicalTrials.gov (to 14 May 2018), and ProQuest Dissertations and Theses Database (to 14 May 2018). SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs comparing psychotropic medication to placebo in people with stroke and emotionalism (also known as emotional lability, pathological crying or laughing, emotional incontinence, involuntary emotional expression disorder, and pseudobulbar affect). DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risk of bias, extracted data from all included studies, and used GRADE to assess the quality of the body of evidence.

The primary emotionalism measures were the proportion of participants achieving at least a 50% reduction in abnormal emotional behaviour at the end of treatment, improved score on Center for Neurologic Study - Lability Scale (CNS-LS), Clinician Interview-Based Impression of Change (CIBIC) or diminished tearfulness. MAIN RESULTS We included seven trials with a total of 239 participants. Two trials were of cross-over design, and outcome data were not available from the first phase (precross-over) in an appropriate format for inclusion as a parallel randomised controlled trial (RCT). Thus, the results of the review are based on five trials with 213 participants. Treatment effects were observed on the following primary endpoints of emotionalism: There is very low quality of evidence from one small RCT that antidepressants increased the number of people who had 50% reduction in emotionalism (RR 16.50, 95% CI 1.07 to 253.40; 19 participants) and low quality evidence from one RCT of improved scores on Center for Neurologic Study - Lability Scale (CNS-LS) and Clinician Interview-Based Impression of Change (CIBIC) with antidepressants (RR 1.44, 95% CI 0.95 to 2.19; 28 participants). There was moderate quality evidence from three RCTS that they increased the number of people who had a reduction in tearfulness (RR 2.18, 95% CI 1.29 to 3.71; 164 participants); and low quality evidence from one RCT of improved scores on the Pathological Laughter and Crying Scale (PLCS) (MD 8.40, 95% CI 11.56 to 5.24; 28 participants).Six trials reported adverse events (death) and found no difference between the groups in death (RR 0.59, 95% CI 0.08 to 4.50; 6 RCTs, 172 participants, moderate-quality evidence). AUTHORS' CONCLUSIONS Antidepressants may reduce the frequency and severity of crying or laughing episodes based on very low quality evidence. Our conclusions must be qualified by several methodological deficiencies in the studies and interpreted with caution despite the effect being very large. The effect does not seem specific to one drug or class of drugs. More reliable data are required before appropriate conclusions can be made about the treatment of post-stroke emotionalism. Future trialists investigating the effect of antidepressants in people with emotionalism after stroke should consider developing and using a standardised method to diagnose emotionalism, determine severity and assess change over time; provide treatment for a sufficient duration and follow-up to better assess rates of relapse or maintenance and include careful assessment and complete reporting of adverse events.

Abstract
The aim of this study was to explore and compare the experiences of tilt-in-space wheelchair use and conventional wheelchair use in severely disabled clients with multiple sclerosis and significant spasticity. The research design was a descriptive qualitative approach, using in-depth audio-taped interviews in clients' homes carried out over a 9-month period. A total of 23 clients (7 tilt-in-space wheelchair users and 16 conventional wheelchair users) were recruited from three adjacent district wheelchair services in South-East England. The criteria for recruitment were that the clients were severely disabled with multiple sclerosis, had significant spasticity and were full-time wheelchair users, usually requiring hoisting. Their carers were also interviewed. The majority of tilt-in-space wheelchair users (6 out of 7) reported that their chairs were comfortable compared with only half of those in conventional wheelchairs (8 out of 16). The positive aspects of tilt-in-space wheelchair provision included comfort, improved postural support, enhanced seating stability, relief of pressure and being able to rest sitting out of bed for prolonged periods, often for more than 6 hours a day. One person reported improved catheter drainage and another reported reduced spasms. The negative aspects of tilt-in-space wheelchairs included their bulky size and lack of manoeuvrability compared with conventional wheelchairs. All the wheelchair users had experienced difficulty with transport and many had relied on family and friends to help with the purchase of expensive adapted vehicles. In conclusion, the majority of the tilt-in-space users were satisfied with their wheelchair, particularly in terms of comfort.

Abstract
A randomized controlled trial was conducted with the aim of evaluating the influence of continued rehabilitative intervention by an occupational therapist on stroke patients after their discharge from a stroke unit. One hundred and ten patients were recruited and randomly allocated to either an intervention group, who were reviewed regularly by an occupational therapist in addition to receiving normal follow-up services, or a control group who received no special intervention. The two groups were compared at one year poststroke. Although there were few significant differences between the two groups at one year in terms of activities of daily living, extended activities of daily living, mood, and perceived quality of life, the number of aids (toilet aids and stair-rails) received by the intervention group was significantly greater (p = 0.05) and the number of readmissions to hospital was significantly smaller (p = 0.03). The provision of a follow-up service by an occupational therapist benefits stroke patients by addressing any problems they have postdischarge, ensuring they receive all necessary aids and helping to maintain them at home.

Abstract
Scales that measure independence in the basic self-care activities of daily living (ADLs) suffer from ceiling effects when applied to an outpatient population. The instrumental activities of daily living (IADL) measures, which assess the performance of tasks required for independence at home are more appropriate. However, validity evaluation of IADL measures seldom goes beyond content validity and little is known about their sensitivity to change. The aim of this study was to evaluate the construct validity of the extended ADL scale (EADL) and to test its sensitivity to change. Three hundred and sixty-one consecutive acute stroke admissions were recruited and surveyed at one, six and 12 months after stroke, using the EADL. There were the expected correlations with the Barthel Index, Nottingham Health Profile, Geriatric Depression Score and the London Stroke Satisfaction Score. Logistic regression analysis showed that, although men were more mobile, they were less likely to carry out domestic and kitchen tasks. Also, nonwhites were more disabled, owner-occupiers had higher leisure scores and those living alone had higher kitchen scores. Analysis of effect sizes showed that the EADL is sensitive to the changes that occur after stroke and would be sensitive to the effect of an intervention that produced a change in independence of two or more ADLs. The EADL is a valid measure of the performance of instrumental ADLs and is sensitive to clinically important changes.

Abstract
Objective: To establish normative data for hip abductors and extensors and to investigate the relationship between these muscles, quadriceps femoris and functional ability. Subjects: Twenty healthy elderly women, mean age 84 ± 3.1 years took part; test-retest reliability was established in six healthy elderly women, mean age 75 ± 9.1 years. Main outcome measures: Isometric hip abductor, hip extensor and quadriceps femoris strength, leg extensor power (LEP), walking speed over 6 m, functional reach and stepping on to blocks of differing height. Results: Intraclass correlations of 0.98 and 0.99 and coefficient of variations (CV) between occasions of 4.7% and 7.2% were established for hip abductor and extensor measurements. The best correlations were between walking speed and strength of quadriceps femoris (p <0.001), between function reach and LEP (p <0.001). LEP was the most significant predictor of functional reach and step height climbed; quadriceps strength was the most significant predictor of walking speed. Conclusions: The data provide a baseline for future studies with less healthy women.

Abstract
Background Traditional treatment for motor impairment after stroke includes medication and physical rehabilitation. The transcranial direct current stimulation associated with a standard physical therapy program may be an effective therapeutic alternative for these patients. Methods This study is a sham-controlled, double-blind, randomized clinical trial aiming to evaluate the efficacy of transcranial direct current stimulation in activities of daily living and motor function post subacute stroke. In total there will be 40 patients enrolled, diagnosed with subacute, ischemic, unilateral, non-recurring stroke. Participants will be randomized to two groups, one with active stimulation and the other with a placebo current. Patients and investigators will be blinded. Everyone will receive systematic physical therapy, based on constraint-induced movement therapy. The intervention will be applied for 10 consecutive days. Patients will undergo three functional assessments: at baseline, week 2, and week 4. Neuropsychological tests will be performed at baseline and week 4. Adverse effects will be computed at each session. On completion of the baseline measures, randomization will be conducted using random permuted blocks. The randomization will be concealed until group allocation. Discussion This study will investigate the combined effects of transcranial direct current stimulation and physical therapy on functional improvement after stroke. We tested whether the combination of these treatments is more effective than physical therapy alone when administered in the early stages after stroke. Trial registration NCT02156635 - May 30, 2014. Randomization is ongoing (40 participants randomized as of the end of December 2015).

Abstract
BACKGROUND AND PURPOSE Robust measures of functional outcome are required to determine treatment effects in stroke trials. Of the various measures available, the Barthel index (BI) is one of the more prevalent. We aimed to describe validity, reliability, and responsiveness (clinimetric properties) of the BI in stroke trials. METHODS Narrative review of published articles describing clinimetric properties or use of the BI as a stroke trial end point. RESULTS Definitive statements on properties of BI are limited by heterogeneity in methodology of assessment and in the content of "BI" scales. Accepting these caveats, evidence suggests that BI is a valid measure of activities of daily living; sensitivity to change is limited at extremes of disability (floor and ceiling effects), and reliability of standard BI assessment is acceptable. However, these data may not be applicable to contemporary multicenter stroke trials. CONCLUSIONS Substantial literature describing BI clinimetrics in stroke is available; however, questions remain regarding certain properties. The "BI" label is used for a number of instruments and we urge greater consistency in methods, content, and scoring. A 10-item scale, scoring 0 to 100 with 5-point increments, has been used in several multicenter stroke trials and it seems reasonable that this should become the uniform stroke trial BI.

Abstract
BACKGROUND Antidepressants may be useful in the treatment of abnormal crying associated with stroke. This is an update of a Cochrane Review first published in 2004. OBJECTIVES To determine whether pharmaceutical treatment reduces the frequency of emotional displays in people with emotionalism after stroke. SEARCH STRATEGY We searched the trials registers of the Cochrane Stroke Group and the Cochrane Depression Anxiety and Neurosis Group (last searched August 2009). In addition, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 3, 2009), MEDLINE (1966 to May 2008), EMBASE (1980 to May 2008), CINAHL (1982 to May 2008), PsycINFO (1967 to May 2008), Arts and Humanities Index (1991 to May 2008), BIOSIS Previews (2002 to May 2008), Science Citation Index (1992 to May 2008), Social Sciences Citation Index (1991 to May 2008), Sociological Abstract/Sociofile (1974 to May 2008), ISI Web of Science (2002 to May 2008), reference lists, clinical trials registers, conference proceedings and dissertation abstracts. We also contacted authors, researchers and pharmaceutical companies. SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing psychotropic medication to placebo in people with stroke and emotionalism (also known as emotional lability or pathological crying and laughing). DATA COLLECTION AND ANALYSIS We obtained data for people who no longer met the criteria for emotionalism, and on reduction in frequency of crying. Primary analyses were the proportion of patients who met the criteria for emotionalism at the end of treatment. Secondary outcomes included emotionalism and depression scores, cognitive function, death, activities of daily living and adverse effects. MAIN RESULTS We included seven trials involving 239 participants. Data were available for five trials with 213 participants. Five trials showed large effects of treatment: 50% reduction in emotionalism, diminished tearfulness, improvements (reduction) in lability, tearfulness and scores on the Pathological Laughter and Crying Scale. However, confidence intervals were wide indicating that treatment may have had only a small positive effect, or even a small negative effect (in one trial). Only two studies systematically reported adverse events; no discernible differences were seen between groups. AUTHORS' CONCLUSIONS Antidepressants can reduce the frequency and severity of crying or laughing episodes. The effect does not seem specific to one drug or class of drugs. Our conclusions must be qualified by several methodological deficiencies in the studies. More reliable data are required before recommendations can be made about the treatment of post-stroke emotionalism.

Abstract
BACKGROUND The benefits of physical exercise in reducing clinically defined depression in the general population have been established, although a review of the evidence for older adults is needed. OBJECTIVES To assess the efficacy of physical exercise for the treatment of depressive symptoms in older adults (>60 years). DATA SOURCES We searched: MEDLINE (1966-May 2008); EMBASE (1980-May 2008); Cumulative Index to Nursing & Allied Health Literature (CINAHL; 1982-May 2008); PsycINFO (1966-May 2008), The Cochrane Library (Issue 2, 2008), and National Research Register (NRR; Issue 2, 2008). REVIEW METHODS Randomized controlled trials and quasi-experimental studies of physical exercise interventions for depression were included where 80% or more of participants were >60 years. Abstracts were assessed to determine whether they met specified inclusion criteria. Primary analysis focused on the prevalence of diagnosable depressive disorder following intervention. Secondary outcome was depression or mood scores on standardized scales. RESULTS Eleven randomized controlled trials with a total of 641 participants were included in the review. Short-term positive outcome for depression or depressive symptoms was found in nine studies, although the mode, intensity and duration of intervention varied across studies. Medium- to long-term effects of intervention were less clear. CONCLUSION Physical exercise programmes obtain clinically relevant outcomes in the treatment of depressive symptoms in depressed older people. Exercise, though not appropriate for all in this population, may improve mood in this group. Further research is needed to establish medium- to long-term effects and cost-effectiveness.

Abstract
BACKGROUND Depression is an important consequence of stroke that impacts on recovery yet is often not detected or inadequately treated. This is an update of a Cochrane review first published in 2004. OBJECTIVES To determine whether pharmaceutical, psychological, or electroconvulsive treatment (ECT) of depression in patients with stroke can improve outcome. SEARCH STRATEGY We searched the trials registers of the Cochrane Stroke Group (last searched October 2007) and the Cochrane Depression Anxiety and Neurosis Group (last searched February 2008). In addition, we searched the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 1, 2008), MEDLINE (1966 to May 2006), EMBASE (1980 to May 2006), CINAHL (1982 to May 2006), PsycINFO (1967 to May 2006) and other databases. We also searched reference lists, clinical trials registers, conference proceedings and dissertation abstracts, and contacted authors, researchers and pharmaceutical companies. SELECTION CRITERIA Randomised controlled trials comparing pharmaceutical agents with placebo, or various forms of psychotherapy or ECT with standard care (or attention control), in patients with stroke, with the intention of treating depression. DATA COLLECTION AND ANALYSIS Two review authors selected trials for inclusion and assessed methodological quality; three review authors extracted, cross-checked and entered data. Primary analyses were the prevalence of diagnosable depressive disorder at the end of treatment. Secondary outcomes included depression scores on standard scales, physical function, death, recurrent stroke and adverse effects. MAIN RESULTS Sixteen trials (17 interventions), with 1655 participants, were included in the review. Data were available for 13 pharmaceutical agents, and four trials of psychotherapy. There were no trials of ECT. The analyses were complicated by the lack of standardised diagnostic and outcome criteria, and differing analytic methods. There was some evidence of benefit of pharmacotherapy in terms of a complete remission of depression and a reduction (improvement) in scores on depression rating scales, but there was also evidence of an associated increase in adverse events. There was no evidence of benefit of psychotherapy. AUTHORS' CONCLUSIONS A small but significant effect of pharmacotherapy (not psychotherapy) on treating depression and reducing depressive symptoms was found, as was a significant increase in adverse events. More research is required before recommendations can be made about the routine use of such treatments.

Abstract
BACKGROUND Many members of the public have negative attitudes towards antidepressants. Psychological interventions are more acceptable but require considerable therapist training. Acceptable psychological interventions that require less training and skill are needed to ensure increased uptake of intervention. A potential intervention of this sort is relaxation techniques. OBJECTIVES To determine whether relaxation techniques reduce depressive symptoms and improve response/remission. SEARCH STRATEGY The register of trials kept by the Cochrane Collaboration Depression, Anxiety and Neurosis Group was searched up to February 2008. We also searched the reference lists of included studies. SELECTION CRITERIA Studies were included if they were randomised or quasi-randomised controlled trials of relaxation techniques (progressive muscle relaxation, relaxation imagery, autogenic training) in participants diagnosed with depression or having a high level of depression symptoms. Self-rated and clinician-rated depression scores and response/remission were the primary outcomes. DATA COLLECTION AND ANALYSIS Two reviewers selected the trials, assessed the quality and extracted trial and outcome data, with discrepancies resolved by consultation with a third. Trial authors were approached for missing data where possible and missing data were estimated or imputed in some cases. Continuous measures were summarised using standardised mean differences and dichotomous outcomes by risk ratios. MAIN RESULTS There were 15 trials with 11 included in the meta-analysis. Five trials showed relaxation reduced self-reported depression compared to wait-list, no treatment, or minimal treatment post intervention (SMD -0.59 (95% CI -0.94 to -0.24)). For clinician-rated depression, two trials showed a non-significant difference in the same direction (SMD -1.35 (95% CI -3.06 to 0.37)).Nine trials showed relaxation produced less effect than psychological (mainly cognitive-behavioural) treatment on self-reported depression (SMD = 0.38 (95% CI 0.14 to 0.62)). Three trials showed no significant difference between relaxation and psychological treatment on clinician-rated depression at post intervention (SMD 0.29 (95% CI -0.18 to 0.75)).Inconsistent effects were found when comparing relaxation training to medication and there were few data available comparing relaxation with complementary and lifestyle treatments. AUTHORS' CONCLUSIONS Relaxation techniques were more effective at reducing self-rated depressive symptoms than no or minimal treatment. However, they were not as effective as psychological treatment. Data on clinician-rated depressive symptoms were less conclusive. Further research is required to investigate the possibility of relaxation being used as a first-line treatment in a stepped care approach to managing depression, especially in younger populations and populations with subthreshold or first episodes of depression.

Abstract
BACKGROUND AND AIMS The aim of this study was to develop a Turkish version of the Nottingham Extended Activities of Daily Living Scale (NEADLS) and to assess its reliability and validity. METHODS Sixty healthy volunteers over 67 years old were included in the study. After translation, the Turkish version of the scale was filled in by each participant over a period of 2 weeks. Reliability was assessed by internal consistency, test-retest intraclass correlation coefficient (ICC) and Spearman's correlation. Converging validity was determined correlating the scale with the Modified Barthel Index (MBI). RESULTS The mean age of participants was 77+/-5.67 years. In the reliability studies, internal consistency within the subsections and items of the NEADLS was good and very good, with Cronbach's alpha values ranging between 0.84-0.93 and 0.74-0.97 respectively. The Cronbach's alpha for the total NEADLS score was also determined as 0.97. Test-retest intraclass correlation coefficients, determined as 0.97 in total score, ranged from 0.84-0.97 between items. The converging validity study for the NEADLS total score was correlated with the MBI and the r value was found statistically significant (r=0.84, p<0.0001). CONCLUSIONS The Turkish version of the NEADLS is a reliable and valid scale and can be used in activities of daily living assessment of Turkish elderly persons.

Abstract
BACKGROUND Depression is an important consequence of stroke that impacts on recovery yet often is not detected or is inadequately treated. OBJECTIVES To determine if pharmaceutical or psychological interventions can prevent depression and improve physical and psychological outcomes in patients with stroke. SEARCH STRATEGY We searched the Trials Registers of the Cochrane Stroke Group (October 2007) and the Cochrane Depression Anxiety and Neurosis Group (February 2008). In addition, we searched the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 1, 2008), MEDLINE (1966 to May 2006), EMBASE (1980 to May 2006), CINAHL (1982 to May 2006), PsycINFO (1967 to May 2006), Applied Science and Technology Plus (1986 to May 2006), Arts and Humanities Index (1991 to September 2002), Biological Abstracts (1969 to September 2002), BIOSIS Previews (2002 to May 2006), General Science Plus (1994 to September 2002), Science Citation Index (1992 to May 2006), Social Sciences Citation Index (1991 to May 2006), SocioFile (1974 to May 2006) ISI Web of Science (2002 to February 2008), reference lists, trial registers, conference proceedings and dissertation abstracts, and contacted authors, researchers and pharmaceutical companies. SELECTION CRITERIA Randomised controlled trials comparing pharmaceutical agents with placebo, or psychotherapy against standard care (or attention control) to prevent depression in patients with stroke. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, extracted data and assessed trial quality. Primary analyses were the proportion of patients who met the standard diagnostic criteria for depression applied in the trials at the end of follow up. Secondary outcomes included depression scores on standard scales, physical function, death, recurrent stroke and adverse effects. MAIN RESULTS Fourteen trials involving 1515 participants were included. Data were available for 10 pharmaceutical trials (12 comparisons) and four psychotherapy trials. The time from stroke to entry ranged from a few hours to seven months, but most patients were recruited within one month of acute stroke. The duration of treatment ranged from two weeks to one year. There was no clear effect of pharmacological therapy on the prevention of depression or other endpoints. A significant improvement in mood and the prevention of depression was evident for psychotherapy, but the treatment effects were small. AUTHORS' CONCLUSIONS A small but significant effect of psychotherapy on improving mood and preventing depression was identified. More evidence is required before recommendations can be made about the routine use of such treatments after stroke.

Abstract
OBJECTIVE To examine and compare the contents of health-related quality of life (HRQoL) measures used in stroke, based on the ICF as the frame of reference. DESIGN We conducted a systematic literature review to select current generic and condition-specific HRQoL measures applied in stroke. We examined the contents of the selected measures by linking the concepts within the instruments' items to the ICF. RESULTS The systematic literature review resulted in the selection of six generic and seven stroke-specific HRQoL measures. Within the selected instruments we identified 979 concepts. To map these concepts, we used 200 different ICF categories. None of the ICF categories is contained in all of the instruments. The most frequently used category is 'b152 Emotional functions' contained in 53 items from 10 instruments. Stroke-specific measures more often address 'Mental functions', while the selected generic instruments more often include Environmental Factors. DISCUSSION The present study provides an overview on current HRQoL measures in stroke with respect to their covered contents and provides valuable information to facilitate the selection of appropriate instruments for specific purposes in clinical as well as research settings.

Abstract
BACKGROUND Accruing evidence from observational and epidemiological studies suggests an inverse relationship between dietary intake of omega 3 polyunsaturated fatty acid (PUFA) and risk of dementia. Postulated mechanisms that might qualify omega 3 PUFA as an interventional target for the primary prevention of dementia include its anti-atherogenic, anti-inflammatory, anti-oxidant, anti-amyloid and neuroprotective properties. OBJECTIVES To review the evidence that omega 3 PUFA supplementation prevents cognitive impairment and dementia in cognitively intact elderly persons. SEARCH STRATEGY The Cochrane Dementia and Cognitive Improvement Group's (CDCIG) Specialized register, MEDLINE, EMBASE,CINAHL PsycINFO, AMED AND CENTRAL and several ongoing trials databases were searched on 5 and 6 October 2005. The CDCIG Register is updated regularly and contains records from all major medical databases and many ongoing trials databases. SELECTION CRITERIA In order to be selected, trials needed to be randomized, placebo-controlled, doubled blinded, of minimum study duration of 6 months, involved persons aged 60 years and above without pre-existing dementia at study onset, and employed cognitive endpoints. DATA COLLECTION AND ANALYSIS Reviewers, working independently, were to select, quality assess and extract relevant data where appropriate and possible. In comparing intervention with placebo, the pooled odds ratios or weighted mean differences and standardized mean difference were to be estimated. MAIN RESULTS There were no randomized trials found in the search that met the selection criteria. Results of two clinical trials are expected in 2008. AUTHORS' CONCLUSIONS There is a growing body of evidence from biological, observational and epidemiological studies that suggests a protective effect of omega 3 PUFA against dementia. However, until data from randomized trials become available for analysis, there is no good evidence to support the use of dietary or supplemental omega 3 PUFA for the prevention of cognitive impairment or dementia.

Abstract
BACKGROUND Antidepressants may be useful in the treatment of abnormal crying associated with stroke. OBJECTIVES To determine whether pharmaceutical treatment reduces the frequency of emotional displays in people who suffer from emotionalism after stroke. SEARCH STRATEGY We searched the Cochrane Stroke Group Trials Register (last searched June 2003). In addition we searched the following electronic databases: Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 3 2002), MEDLINE (1966 to September 2002), EMBASE (1980 to September 2002), CINAHL (1982 to September 2002), PsychINFO (1967 to September 2002), Applied Science and Technology Plus (1986 to September 2002), Arts and Humanities Index (1991 to September 2002), Biological Abstracts (1969 to September 2002), General Science Plus (1994 to September 2002), Science Citation Index (1992 to September 2002), Social Sciences Citation Index (1991 to September 2002), and Sociofile (1974 to September 2002). We searched reference lists from relevant articles and textbooks, and contacted authors of known studies and pharmaceutical companies who manufacture psychotropic medications. SELECTION CRITERIA Randomised and quasi-randomised controlled trials, comparing psychotropic medication to placebo, in people with stroke and emotionalism (also known as emotional lability or pathological crying and laughing). DATA COLLECTION AND ANALYSIS Data were obtained on people who no longer met criteria for emotionalism, as defined in studies, and on reduction in frequency of crying at the end of treatment. Data were not pooled because of the multiplicity of definitions and outcome measures. MAIN RESULTS Five trials involving 103 participants were included. Four trials showed large effects of treatment: 50% reduction in emotionalism, improvements (reduction) in the frequency of compulsive laughter, and lower (better) scores on the Pathological Laughter and Crying scale. The confidence intervals were wide, however, indicating that treatment may have had only a small positive effect, or even a small negative effect (in one trial). Subgroup analysis was not performed due to the multiple methods of assessment of emotionalism within and between trials. Only one study systematically recorded and reported adverse events; no discernible difference was seen between groups. Participants allocated active treatment were more likely to leave early from trials. REVIEWERS' CONCLUSIONS Antidepressants can reduce the frequency and severity of crying or laughing episodes. The effect do not seem specific to one drug or class of drugs. However, our conclusions must be qualified by several methodological deficiencies in the studies. More reliable data are required before recommendations can be made about the treatment of post-stroke emotionalism.

Abstract
BACKGROUND Depressive and anxiety disorders following stroke are often undiagnosed or inadequately treated. This may reflect difficulties with the diagnosis of abnormal mood among older people with stroke-related disability, but may also reflect uncertainty about the effectiveness of such therapies in this setting. OBJECTIVES To determine whether pharmacological, psychological, or electroconvulsive treatment (ECT) of depression in patients with stroke can improve outcome. SEARCH STRATEGY The Cochrane Stroke Group Trials Register (last searched June 2003). The Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 3, 2002), MEDLINE (1966 to September 2002), EMBASE (1980 to September 2002), CINAHL (1982 to September 2002), PsychINFO (1967 to September 2002), Applied Science and Technology Plus (1986 to September 2002), Arts and Humanities Index (1991 to September 2002), Biological Abstracts (1969 to September 2002), General Science Plus (1994 to September 2002), Science Citation Index (1992 to September 2002), Social Sciences Citation Index (1991 to September 2002), and Sociofile (1974 to September 2002). Reference lists from relevant articles and textbooks were searched, and authors of known studies and pharmaceutical companies who manufacture psychotropic medications were contacted. SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing different types of pharmaceutical agents with placebo, or various forms of psychotherapy with standard care (or attention control), in patients with recent, clinically diagnosed, acute stroke, where treatment was explicitly intended of treat depression. DATA COLLECTION AND ANALYSIS Primary analyses focussed on the prevalence of diagnosable depressive disorder at the end of treatment. Secondary outcomes included depression or mood scores on standard scales, disability or physical function, death, recurrent stroke, and adverse effects. We did not pool the data for summary scores. We performed meta-analysis for only some binary endpoints and data on adverse events. MAIN RESULTS Nine trials, with 780 participants, were included in the review. Data were available for seven trials of pharmaceutical agents, and two trials of psychotherapy. There were no trials of ECT. The analyses were complicated by the lack of standardised diagnostic and outcome criteria, and differing analytic methods. There was no strong evidence of benefit of either pharmacotherapy or psychotherapy in terms of a complete remission of depression following stroke. There was evidence of a reduction (improvement) in scores on depression rating scales, and an increase in the proportion of participants with anxiety at the end of follow up. REVIEWERS' CONCLUSIONS This review found no evidence to support the routine use of pharmacotherapeutic or psychotherapeutic treatment for depression after stroke. More research is required before recommendations can be made about the most appropriate management of depression following stroke.

Abstract
BACKGROUND Abnormal mood is an important consequence of stroke and may affect recovery and outcome. However, depression and anxiety are often not detected or inadequately treated. This may in part be due to doubts about whether anti-depressant treatments commenced early after the onset of stroke will prevent depression and improve outcome. OBJECTIVES To determine if pharmaceutical or psychological interventions can prevent the onset of depression, including depressive illness and abnormal mood, and improve physical and psychological outcomes, in patients with stroke. SEARCH STRATEGY We searched the Cochrane Stroke Group trials register (June 2003). In addition we searched the following electronic databases: Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 3, 2002), MEDLINE (1966 to September 2002), EMBASE (1980 to September 2002), CINAHL (1982 to September 2002), PsychINFO (1967 to September 2002), Applied Science and Technology Plus (1986 to September 2002), Arts and Humanities Index (1991 to September 2002), Biological Abstracts (1969 to September 2002), General Science Plus (1994 to September 2002), Science Citation Index (1992 to September 2002), Social Sciences Citation Index (1991 to September 2002), and Sociofile (1974 to September 2002). Reference lists from relevant articles and textbooks were searched, and authors of known studies and pharmaceutical companies who manufacture psychotropic medications were contacted. SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing different types of pharmaceutical agents (eg selective serotonin reuptake inhibitors) with placebo, or various forms of psychotherapy against standard care (or attention control), in patients with a recent clinical diagnosis of stroke, where the treatment was undertaken with the explicit intention of preventing depression. DATA COLLECTION AND ANALYSIS The primary analyses focussed on the proportion of patients who met the standard diagnostic criteria for depression applied in the trials at the end of follow-up. Secondary outcomes included depression or mood scores on standard scales, disability or physical function, death, recurrent stroke, and adverse effects. MAIN RESULTS Twelve trials involving 1245 participants were included in the review. Data were available for nine trials (11 comparisons) involving different pharmaceutical agents, and three trials of psychotherapy. The time from stroke onset to entry ranged from a few hours to six months, but most patients were recruited within one month of acute stroke. The duration of treatments ranged from two weeks to one year. There was no clear effect of pharmacological therapy on the prevention of depression or on other measures. A significant improvement in mood was evident for psychotherapy, but this treatment effect was small and from a single trial. There was no effect on diagnosed depression. REVIEWERS' CONCLUSIONS This review identified a small but significant effect of psychotherapy on improving mood, but no effect of either pharmacotherapy or psychotherapy on the prevention of depressive illness, disability, or other outcomes. More evidence is therefore required before any recommendations can be made about the routine use of such treatments to improve recovery after stroke.

Abstract
BACKGROUND AND PURPOSE To compare a community-based multidisciplinary stroke team (CST) approach with hospital-based rehabilitation in terms of hospital stay, functioning, quality of life, and service use and costs. METHODS Stroke patients who met pre-agreed criteria were allocated randomly to the CST service (n=59) or to usual inpatient rehabilitation and follow-up care (n=54). Assessments were completed at randomization and 12 months later. Caregiver strain and satisfaction (n=55) were also assessed. Cost data were collected for a subsample of 38 patients. RESULTS Almost 80% of surviving patients (n=691) were discharged home and a small number (n=55) were readmitted. Approximately 17% (113/649) were randomized. There were no statistically significant differences in hospital duration, costs, or outcome measures at baseline and 12 months except for higher satisfaction reported by CST patients. Overall, both groups recorded improvement in most domains over time. Carers reported a high level of satisfaction although the level of strain among carers is cause for concern. The community group (n=18) cost less than the hospital group (n=20). CONCLUSIONS A mixed model of hospital-based and community-based rehabilitation services is likely to lead to increased patient choice and satisfaction and a potential reduction in bed pressures for less severe stroke patients.

Abstract
OBJECTIVE To examine the impact of fitness training with recently brain-injured inpatients on exercise capacity and functional and psychologic outcome measures. DESIGN A randomized controlled trial of exercise versus relaxation training for 3 months. Blind assessments were conducted before and after the end of a 12-week training program, as well as at follow-up assessment 12 weeks posttraining. SETTING Four regional neurologic inpatient rehabilitation units. PATIENTS Of 157 patients recruited 24 +/- 14 weeks after single-incident brain injury, 142 patients were assessed at week 12, and 128 patients at follow-up. INTERVENTIONS Patients were randomized between cycle ergometer aerobic training and a relaxation training control condition, which was theoretically inert with respect to cardiovascular fitness. MAIN OUTCOME MEASURES Validation of exercise training (peak work rate, peak heart rate, body mass index); mobility and physical function (modified Ashworth scale, Berg balance scale, Rivermead Mobility Index, 10-m walk velocity); disability and dependency (Barthel index, FIMtrade mark instrument, Nottingham Extended Activities of Daily Living); and psychologic function (fatigue questionnaire, Hospital Anxiety and Depression Scale). RESULTS Significant improvements in exercise capacity (p <.05) in the exercise training group (n = 70) relative to the control group (n = 72) were not matched by greater improvements in functional independence, mobility, or psychologic function, at either 12 weeks or follow-up. CONCLUSIONS The benefits of improved cardiovascular fitness did not appear to extend to measurable change in function or psychologic state.

Abstract
OBJECTIVE To ensure at outset the content validity of a measure (to be developed) of social integration following stroke. DESIGN Qualitative study, using in-depth interviews with patients at least six months following stroke. SETTING Community setting, Bristol, UK. SUBJECTS Thirty survivors of stroke, discharged at least six months previously from a neurological rehabilitation unit in a district general hospital. RESULTS Patients reported a change, usually for the worse, in their levels of integration following stroke. More specifically they alluded to a decrease in both the quantity and quality of activities, especially with regard to leisure and those activities occurring outside the home. Social interaction was reduced in most patients, in terms of frequency and quality of contact. From the data, six dimensions of change in quality of interaction emerged. Finally, changes in patients' physical and financial environments were reported. Based on the findings, four diagrams were developed, providing a structure for questionnaire development. CONCLUSIONS The results of this study confirm the findings of previously reported research. An individual's level of social integration can be affected by stroke in a wide variety of areas and along many different dimensions. Data from this study have highlighted the importance of the patient's subjective impression of the quality of both functional and social performance. This has provided the opportunity to develop a questionnaire based on the patient's perspective, rather than that of health professionals.

Abstract
For the successful achievement of evidence-based practice, clinicians, managers and purchasers need evidence on whether a particular intervention works and ways to judge the appropriateness of the outcome criteria and measures used. Guidance is needed on what outcome measure to use, especially within routine clinical care settings. Beginning with a reclarification of the difference between a health status and an outcome measure, the paper presents an evaluative checklist for use by clinical audit and research staff to review outcome measures for use in routine care settings. Central features include the user-centredness of the measure, its psychometric properties, feasibility of use and utility. The applicability of the checklist is illustrated for outcome measurement in diabetes and stroke care. A modified form of the checklist is proposed for use by the busy clinician as an aid to the critical review of research papers within the context of evidence-based practice and to aid health care practitioners' choice of which outcome measure(s) to use within routine clinical care.

Abstract
BACKGROUND AND PURPOSE Adequate outcome assessment is crucial to randomized trials. We wished to assess the types of outcomes used in acute stroke trials and the appropriateness of these outcomes and their analyses. METHODS Acute stroke trials from the Cochrane Stroke Group's database were included from 1955 to 1995 if they were published in full text in English. For each trial we collected year of publication, number of patients randomized, blinding of outcome assessment, the specific outcome instruments used, the statistical methods used for analysis, and the significance of the results. The validity and reliability of each outcome measure were assessed by review of the literature. RESULTS Our study included 174 trials. Outcomes were assessed blindly in 69%. Death was recorded in only 76% of trials, impairment in 76%, disability in 42%, and handicap or quality of life in only 2%. Of the trials that measured impairment, 35% used a measure of established validity or reliability. For disability and handicap, the proportions with valid or reliable measures were 70% and 25%, respectively. Impairment and handicap measures were primarily analyzed as continuous variables, while disability was mainly analyzed as a dichotomous variable. Continuous data were usually analyzed with inappropriate parametric statistics. There was no relationship between the method of analysis, the type of outcome, and the statistical significance of results. CONCLUSIONS Most acute stroke trials up to 1995 have used clinical outcome measures that were inadequate in terms of their content, reliability, validity, blinded assessment, and statistical analysis. This has important implications for future stroke research.

Abstract
Despite the considerable amount of research that has been undertaken on poststroke depression, a review of the literature demonstrates that there are many inconclusive findings in the area. In particular, the causes and course of the disorder remain to be firmly established. While studies of prevalence differ with respect to the nature and timing of their assessment procedures, most conclude that poststroke depression has a negative impact on the rehabilitation of the stroke patient. Very little research is available on te relationship between poststroke depression and care-giver burden. However, recent studies have adopted more rigorous methodological procedures, allowing some insights into the complex mixture of factors which determine the occurrence of poststroke depression.

Abstract
Health-related quality of life (HRQL) measures have been developed from the utilitarian ethical perspective of public health medicine which may be contrasted with individual-centered indicators; these emphasise the unique experience of a patient. The impairment-disability-handicap framework provides a more complete description of disease consequences and health outcomes than a generic HRQL indicator. The assessment of reliability and validity of HRQL indicators is often carried out inappropriately: population repeatability is measured when an indicator will be used to examine changes in individuals; between observer variation may be large compared with variation between populations. Content and construct validity are usually measured but the more important predictive validity is neglected. Effect sizes of HRQL indicators are likely to be inflated by use of between subject estimates of variance but the more appropriate within subject variance is seldom reported. HRQL indicators are of very limited value for many clinical and public health tasks: monitoring health of individuals and populations; evaluating the effects of health and social policy; allocating resources; evaluating the effects of treatment. Alternative methods of assessment derived from the impairment-disability-handicap conceptual framework are preferable.

Abstract
BACKGROUND Functional assessment in stroke patients is critical in both clinical practice and outcome studies. Ability in the areas relating to instrumental activities of daily living (IADL) that require increased interaction with the environment, whether household or community, appears to be a prerequisite for independent living in the community. The majority of the research in this area has been in the geriatric population. A literature review was undertaken to answer the following questions: What is a working definition of IADL? What are the criteria that determine inclusion with specific applicability in the stroke population? What are the reliability and validity of available measures in the stroke population? What is the relevance of IADL to functional outcome? SUMMARY OF REVIEW The findings at this time indicate that there is no consensus for a clear definition of IADL. The terminology used includes the original IADL as described by Lawton and Brody, extended ADL, social ADL, and advanced ADL. Four scales that were designed primarily for use in the stroke population were identified: the Nottingham Extended ADL (a self-report scale), the Hamrin Activity Index and the Frenchay Activities Index (both based on patient interviews), and the Household section of the Rivermead ADL Assessment (a performance index). CONCLUSIONS There is some published evidence concerning the validity, reliability, utility, sensitivity, or hierarchical nature of these indexes, and further testing is needed. The items in each index, however, have inherent relevance with potential for use in future clinical research.

Abstract
This study aimed to cross validate the Guy's prognostic score in a new sample of patients of all ages admitted to hospital with a stroke and to devise and test a simpler version (the G-score). 361 consecutive acute patients with stroke who had been admitted to the acute hospitals in two adjacent health districts in East London were recruited and followed up for six months after the stroke. The G-score was derived by simplifying the weights used in calculating the Guy's score. With the conventional threshold of 0 for the Guy's score and 3 (out of 7) for the G-score, the sensitivity of both scores for predicting a bad outcome (death or Barthel score < 13 out of 20 at six months) was 0.72 and specificity was 0.63. The likelihood ratio for the Guy's score was 1.97 and for the G-score 1.95. Both versions of the score performed better than conscious level alone at predicting the outcome (sensitivity 0.47, specificity 0.73, likelihood ratio 1.74). Similar data are presented for different thresholds and prior probabilities. In addition, the G-score permits direct estimation of 95% confidence intervals for the probability of a bad outcome for five grades of stroke severity. Outcome prediction with multivariate techniques has the potential to improve and inform clinical decision making. The G-score should be used to define stroke severity for individual patients and for case mix adjustment.

Abstract
The aim was to determine the handicap experienced by subjects one year after a stroke, and assess the acceptability, validity, and reliability of a new handicap measurement scale. A cross sectional survey of 141 survivors of a cohort of consecutive hospital admissions with acute stroke was undertaken. The London handicap scale (a new health outcome measurement scale), Barthel index, Nottingham extended activities of daily living scale, Nottingham health profile, Geriatric depression score, and a global life satisfaction scale were used. 94 subjects (67%) responded to a single mailing; 89 (95%) responses were usable. Mean handicap was 0.40 (range 0.06-1.0, SD 0.20) on a scale of 0 (maximum handicap) to 1 (no handicap). All handicap dimensions showed a wide range of problems, with physical independence and occupation particularly affected. Correlations between handicap score and other outcome measures were all in the expected direction and of about the strength expected (0.36 < r < 0.69). The reliability coefficient was 0.91, limits of agreement +/- 0.19. The measurements demonstrated substantial handicap one year after a stroke, reflecting considerable unmet rehabilitation needs. The scale proved acceptable to subjects, and the results were consistent with good validity.
