Effect of a Therapeutic Intervention for the Hemiplegic Upper Limb in the Acute Phase After Stroke A Single-Blind, Randomized, Controlled Multicenter Trial

BACKGROUND AND PURPOSE Arm function recovery is notoriously poor in stroke patients. The effect of treatment modalities, particularly those directed at improving upper limb function, has been studied primarily in chronic stroke patients. The purpose of this study was to investigate the effect of a specific therapeutic intervention on arm function in the acute phase after stroke. METHODS In a single-blind, randomized, controlled multicenter trial, 100 consecutive patients were allocated to either an experimental group that received an additional treatment of sensorimotor stimulation or to a control group. The intervention was applied for 6 weeks. Patients were evaluated for level of impairment (Brunnström-Fugl-Meyer test) and disability (Action Research Arm test, Barthel Index) before, midway, and after the intervention period and at follow-up 6 and 12 months after stroke. RESULTS Patients in the experimental group performed better on the Brunnström-Fugl-Meyer test than those in the control group throughout the study period, but differences were significant only at follow-up. Results on the Action Research Arm test and Barthel Index revealed no effect at the level of disability. The effect of the therapy was attributed to the repetitive stimulation of muscle activity. The treatment was most effective in patients with a severe motor deficit and hemianopia or hemi-inattention. No adverse effects due to the intervention were found. CONCLUSIONS Adding a specific intervention during the acute phase after stroke improved motor recovery, which was apparent 1 year later. These results emphasize the potential beneficial effect of therapeutic interventions for the arm.

Use of Time by Stroke Patients. A Comparison of Four European Rehabilitation Centers

Background and Purpose— Differences exist between European countries in the proportion of patients who die or become dependent after stroke. The aim of the present study was to identify differences in the use of time by stroke patients in 4 rehabilitation centers in 4 European countries. Methods— In each of the 4 centers, 60 randomly selected stroke patients were observed at 10-minute intervals using behavioral mapping. Observations took place on 30 weekdays selected at random, on equal numbers of morning, afternoon, and evening sessions. A logistic generalized estimating equation model with correction for differences in case mix and multiple testing was used for the analysis. Results— Overall time available from different professions was the highest in the United Kingdom, but patients in the United Kingdom spent on average only 1 hour per day in therapy. This was significantly less than patients in Belgium and Germany, who spent ≈2 hours, and patients in Switzerland who spent ≈3 hours per day in therapy. In all centers, patients spent less than half their time in interactions and >72% of the time in nontherapeutic activities. Conclusions— Important differences in the use of time were established, which appeared dependent on management decisions rather than the number of staff available. Patients in the Swiss and German centers spent more time in therapy, possibly because of the structured organization of rehabilitation. Further studies will verify whether this has an effect on outcome.

Motor and Functional Recovery After Stroke A Comparison of 4 European Rehabilitation Centers

Background and Purpose— Outcome after first stroke varies significantly across Europe. This study was designed to compare motor and functional recovery after stroke between four European rehabilitation centers. Methods— Consecutive stroke patients (532 patients) were recruited. They were assessed on admission and at 2, 4, and 6 months after stroke with the Barthel Index, Rivermead Motor Assessment of Gross Function, Rivermead Motor Assessment of Leg/Trunk, Rivermead Motor Assessment of Arm, and Nottingham Extended Activities of Daily Living (except on admission). Data were analyzed using random effects ordinal logistic models adjusting for case-mix and multiple testing. Results— Patients in the UK center were more likely to stay in lower Rivermead Motor Assessment of Gross Function classes compared with patients in the German center (&Dgr;OR, 2.4; 95% CI, 1.3 to 4.3). In the Swiss center, patients were less likely to stay in lower Nottingham Extended Activities of Daily Living classes compared with patients in the UK center (&Dgr;OR, 0.7; 95% CI, 0.5 to 0.9). The latter were less likely to stay in lower Barthel Index classes compared with the patients in the German center (&Dgr;OR, 0.6; 95%CI, 0.4 to 0.8). Recovery patterns of Rivermead Motor Assessment of Leg/Trunk and Rivermead Motor Assessment of Arm were not significantly different between centers. Conclusions— Gross motor and functional recovery were better in the German and Swiss centers compared with the UK center, respectively. Personal self-care recovery was better in the UK compared with the German center. Previous studies in the same centers indicated that German and Swiss patients received more therapy per day. This was not the result of more staff but of a more efficient use of human resources. This study indicates potential for improving rehabilitation outcomes in the UK and Belgian centers.

Characterizing Rehabilitation Services for Patients With Knee and Hip Replacement in Skilled Nursing Facilities and Inpatient Rehabilitation Facilities

OBJECTIVE To characterize rehabilitation services for patients with knee and hip replacement in 3 types of postacute facilities in the U.S. DESIGN Multi-site prospective observational cohort study. SETTING Eight freestanding skilled nursing facilities (SNFs), 1 hospital-based SNF, and 11 inpatient rehabilitation facilities (IRFs). PARTICIPANTS Patients (N=2158) with knee or hip replacement. INTERVENTIONS No new interventions. MAIN OUTCOME MEASURES Length of stay (LOS), amount and intensity of physical therapy (PT) and occupational therapy (OT), types of therapy activities. RESULTS Average LOS was about 15 days for freestanding SNF patients, and 9 to 10 days for hospital-based SNF and IRF patients. Freestanding SNFs and IRFs provide about the same number of hours of PT and OT; the hospital-based SNF provided 27% fewer hours. Freestanding SNFs and the hospital-based SNF provided fewer hours a day than did IRFs. Joint replacement patients across all 3 types of facilities spent, on average, 70% to 75% of their PT time in just 2 activities--exercise and gait and spent 56% to 66% of their OT time in 3 activities--exercise, functional mobility, and dressing lower body. CONCLUSIONS Both freestanding SNFs and IRFs provided similar amounts of PT with a similar emphasis on exercise and gait activities. IRFs, however, provided more OT than freestanding SNFs. IRFs had shorter LOSs and more intensive therapy services than freestanding SNFs. Study freestanding SNFs exhibited greater variation in LOS and intensity of therapy than IRFs.

Stroke Rehabilitation in Europe What Do Physiotherapists and Occupational Therapists Actually Do

Background and Purpose— Physiotherapy (PT) and occupational therapy (OT) are key components of stroke rehabilitation. Little is known about their content. This study aimed to define and compare the content of PT and OT for stroke patients between 4 European rehabilitation centers. Methods— In each center, 15 individual PT and 15 OT sessions of patients fitting predetermined criteria were videotaped. The content was recorded using a list comprising 12 therapeutic categories. A generalized estimating equation model was fitted to the relative frequency of each category resulting in odds ratios. Results— Comparison of PT and OT between centers revealed significant differences for only 2 of the 12 categories: ambulatory exercises and selective movements. Comparison of the 2 therapeutic disciplines on the pooled data of the 4 centers revealed that ambulatory exercises, transfers, exercises, and balance in standing and lying occurred significantly more often in PT sessions. Activities of daily living, domestic activities, leisure activities, and sensory, perceptual training, and cognition occurred significantly more often in OT sessions. Conclusion— This study revealed that the content of each therapeutic discipline was consistent between the 4 centers. PT and OT proved to be distinct professions with clear demarcation of roles.

Anxiety and depression in the first six months after stroke. A longitudinal multicentre study

Purpose. To document the prevalence, severity and time course of anxiety and depression in stroke rehabilitation patients in four European countries. Method. At two, four and six months post-stroke, the prevalence and severity of anxiety and depression were determined in 532 consecutively recruited patients, using the Hospital Anxiety and Depression Scale. Time course of prevalence and severity was examined, using Cochran-Q and Friedman-tests, respectively. We identified whether the numbers of anxious/depressed patients at each time point comprised the same individuals. Results. Prevalence of anxiety ranged between 22% and 25%; depression between 24% and 30%. Median severity ranged between 4 and 5. No significant differences between centres occurred (p > 0.05). Prevalence of both disorders was not significantly different over time. Severity of anxiety decreased between four and six months; severity of depression remained stable. About 40% of the patients with initial anxiety remained anxious at six months. Some 11% and 7% of those initially not anxious became anxious at four or six months after stroke, respectively. Depression showed a similar pattern. Conclusions. Despite differences in patient profiles and intensity of rehabilitation, no significant differences occurred between centres in prevalence and severity of both disorders. Anxiety was almost as common as depression and additional patients became anxious/depressed at each time point.

Joint Replacement Rehabilitation Outcomes on Discharge From Skilled Nursing Facilities and Inpatient Rehabilitation Facilities

OBJECTIVE To compare functional outcomes at discharge across postacute settings. DESIGN Prospective observational cohort study. SETTING Eleven inpatient rehabilitation facilities (IRFs), 8 freestanding skilled nursing facilities (SNFs), and 1 hospital-based SNF from across the United States. PARTICIPANTS Consecutively enrolled patients (N=2152): patients with knee replacement (n=1401) and patients with hip replacement (n=751). INTERVENTIONS None; examination of existing practice patterns. MAIN OUTCOME MEASURE FIM discharge motor score. RESULTS Freestanding SNF patients entered with higher motor FIM scores and left with higher scores than did IRF patients. IRF patients, however, achieved larger motor FIM gains and achieved them in a shorter time. In multivariate models controlling for patient differences and onset days, IRFs were associated with better discharge motor outcomes, but the overall setting effect was not large. The largest motor FIM differences were between medium-volume IRFs and low-volume freestanding SNFs: 4.6 motor FIM points for patients with knee replacement and 7.3 motor FIM points for patients with hip replacement. Other differences between settings were much smaller. Multivariate models explained between a third and a half of the variance in outcome. CONCLUSIONS As a group, IRFs had better motor FIM outcomes than did SNFs, but the size of the IRF advantage was not large. Other important facility and practice characteristics also were associated with discharge outcomes after joint replacement rehabilitation. Earlier and more intensive rehabilitation was associated with better outcomes. The volume of joint replacement patients seen by a facility also plays a part: medium-volume facilities among both SNFs and IRFs had better outcomes.

Determinants of the number of antenatal visits in a metropolitan region

BackgroundAntenatal care has a positive effect on pregnancy, both clinically and psychologically, but consensus about the optimal number of antenatal visits is lacking. This study aims to provide insight into the dynamics of the number of antenatal visits a woman receives. Independent effects of predisposing, enabling and pregnancy-related determinants are examined.MethodsWomen were recruited in nine clinical centres in the Brussels Metropolitan region. Antenatal care use was measured prospectively. A Poisson regression model was applied to measure the independent effect of individual determinants on the number of antenatal visits.ResultsData on antenatal care trajectories in 333 women were collected. The multivariate analyses showed that women with a Maghreb or Turkish origin had 14% fewer visits compared with European (EU15) women. More highly educated women had 22% more visits compared with those with a low education. Women with a high income had 14% more antenatal visits compared with those with a low income. Fewer antenatal visits were observed in multiparae (15%), women initiating care after 14 weeks of gestation (31%), women without medical risks during the pregnancy (12%) and in women with a continuity of care index of 50% or more (12%). More visits were observed in delivering after week 37 (22% increase).ConclusionsPredisposing and enabling factors have to be considered when antenatal care programmes are evaluated in a metropolitan area. Variations in the number of antenatal visits show that socially vulnerable women are more at risk of having fewer visits.

Anxiety and depression after stroke: a 5 year follow-up

Purpose: The aim was to document the prevalence and predictors of anxiety and depression 5 years after stroke, across four European centres. Method: A cohort of 220 stroke patients was assessed at 2, 4 and 6 months and 5 years after stroke. Patients were assessed on the Hospital Anxiety and Depression Scale and measures of motor function and independence in activities of daily living. Results: At 5 years, the prevalence of anxiety was 29% and depression 33%, with no significant differences between centres. The severity of anxiety and depression increased significantly between 6 months and 5 years. Higher anxiety at 6 months and centre were significantly associated with anxiety at 5 years, but not measures of functional recovery. Higher depression scores at 6 months, older age and centre, but not measures of functional recovery, were associated with depression at 5 years. Conclusions: Anxiety and depression were more frequent at 5 years after stroke than at 6 months. There were significant differences between four European centres in the severity of anxiety and depression. Although the main determinant of anxiety or depression scores at 5 years was the level of anxiety or depression at 6 months, this accounted for little of the variance. Centre was also a significant predictor of mood at 5 years. There needs to be greater recognition of the development of mood disorders late after stroke and evaluation of variation in management policies across centres. Implications for Rehabilitation Depression and anxiety persisted up to 5 years after stroke in about a third of patients. Variation in the rates of anxiety and depression between different European centres suggest management policies rather than stroke related factors may determine their persistence. The effect of variations in stroke management policies should be investigated. Patients’ mood should be monitored over time in order to detect those with late onset mood disorders after stroke.

INPATIENT STROKE REHABILITATION: A COMPARATIVE STUDY OF ADMISSION CRITERIA TO STROKE REHABILITATION UNITS IN FOUR EUROPEAN CENTRES

OBJECTIVE To explore the clinical and non-clinical factors involved in decision-making concerning admission to European stroke rehabilitation units. DESIGN Observational study on case-mix at intake combined with questionnaires and semi-structured interviews with the medical consultants of each European stroke rehabilitation unit. PATIENTS AND SETTINGS Clinical data on 532 first-ever patients after stroke. Medical consultants from 6 European stroke rehabilitation units in 4 European countries (UK, Belgium, Germany and Switzerland). METHODS Standardized clinical assessments within 2 days after admission. Questionnaires to each medical consultants followed by a qualitative round of semi-structured interviews. RESULTS Case-mix of patients after stroke was significantly different between European stroke rehabilitation units. Clinical criteria for admission were seldom explicit and were evaluated differently between the European stroke rehabilitation units. In the UK units, diagnosis of stroke was the only criterion for admission. In the Belgian, German and Swiss units, pre-morbid conditions were taken into account in admission decisions. The likelihood of discharge home was considered highly important in the Swiss units. CONCLUSION Case-mix differences at intake could be linked to different appraisals of clinical and non-clinical factors of patients after stroke. The findings urge us to be more explicit about decision-making processes at admission in order to provide a more comprehensive insight into the interplay between context and process of care.
