Changes in Upper Limb Capacity and Performance in the Early and Late Subacute Phase After Stroke.

BACKGROUND: The course of spontaneous biological recovery indicates that no essential improvements in upper limb (UL) capacity should be expected 3 months after stroke. Likewise, UL performance as assessed with accelerometers does not seem to increase. However, this plateau may not apply to all patients with stroke. OBJECTIVES: This study aimed to investigate the changes in UL capacity and performance from 3 to 6 months post-stroke, and the association between patients' UL capacity and actual UL performance. METHODS: This study was a secondary analysis of a prospective longitudinal cohort study. Patients with UL impairment and first or recurrent stroke were included. Their UL capacity was assessed at 3 and 6 months with the Action Research Arm Test (ARAT) and UL performance was examined with accelerometry and expressed as a use ratio. The association between ARAT and use ratio was examined with multiple regression analyses. RESULTS: Data from 67 patients were analyzed. It was shown that UL capacity as assessed with ARAT still improved from 3 to 6 months. A clinically meaningful improvement (≥ 6 points on ARAT) was found in 16 (46%) of the 35 patients whose scores allowed for such an increase. Improvements were mainly observed for patients with ARAT scores in the range of 15-51 at 3 months. Conversely, UL performance did not change. Three and 6 months after stroke respectively 69% and 64% of the variation in use ratio was explained by ARAT. CONCLUSION: While a substantial part of patients improved their UL capacity, UL performance did not change from 3 to 6 months post-stroke. Strategies to remind patients of including their affected UL may encourage the transfer from better capacity to increased performance.

Functional Independence: A Comparison of the Changes During Neurorehabilitation Between Patients With Nontraumatic Subarachnoid Hemorrhage and Patients With Intracerebral Hemorrhage or Acute Ischemic Stroke.

OBJECTIVE: To compare the changes in functional independence measured by the FIM after specialized neurorehabilitation between patients with nontraumatic subarachnoid hemorrhage (SAH) and patients with intracerebral hemorrhage (ICH) or acute ischemic stroke (AIS). DESIGN: Historical cohort study comparing changes in functional independence between patients with nontraumatic SAH and those with ICH/AIS, using FIM scores from a local database and clinical information from the Danish National Patient Registry. SETTING: Postacute specialized inpatient neurorehabilitation. PARTICIPANTS: Participants (N=660) comprised patients with a first-time nontraumatic SAH (n=212) and age-matched patients with a first-time ICH/AIS (n=448). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Crude and adjusted comparisons of FIM (total and item by item) measured at baseline and at discharge. RESULTS: Patients with nontraumatic SAH were admitted with a lower functional level compared with patients with ICH/AIS (median total FIM score, 25 [interquartile range (IQR), 18-81] vs 78.5 [IQR, 47-107]), and discharged with a lower functional level (median total FIM score, 98 [IQR, 40-116] vs 110 [IQR, 82.5-119]), although they made more progress during neurorehabilitation (median change in total FIM score, 27 [IQR, 4-60] vs 17 [IQR, 7-35]). Statistically, patients with nontraumatic SAH had significantly better odds for obtaining functional independence than did patients with ICH/AIS in 6 of the 18 FIM items: eating (odds ratio [OR]=3.2; 95% confidence interval [CI], 1.7-5.8); dressing-upper body (OR=2.0; 95% CI, 1.1-3.5); transfer tub/shower (OR=2.0; 95% CI, 1.1-3.6); stair walking (OR=2.2; 95% CI, 1.3-3.7); comprehension (OR=2.3; 95% CI, 1.3-3.9); and expression (OR=3.6; 95% CI, 2.0-6.5). CONCLUSIONS: Patients with nontraumatic SAH made significantly more progress during neurorehabilitation, although they were discharged with a lower level of functional independence compared with patients with ICH/AIS. However, both patients with nontraumatic SAH and those with ICH/AIS improved their functional outcome significantly. Also, patients with nontraumatic SAH admitted with severe functional outcome were shown to be capable of recovering to a moderate level of functional independence.

Healthcare Professionals' Experiences with Rehabilitation Practices for Patients with Cognitive Impairment after Stroke in North Norway: A Qualitative Study.

Methods: A focus group interview with clinicians, coordinators, and leaders involved in stroke survivors' rehabilitation trajectories was conducted. The group consisted of a strategic selection of participants with diverse professional backgrounds from specialist and primary healthcare services. The transcribed material was analyzed thematically using systematic text condensation based on an inductive, interpretive approach. Results: We found that patients with mild and moderate cognitive impairment after stroke were characterized as a neglected group in rehabilitation services and that neglect was related to both structural and professional issues. First, neglect seemed partly related to the availability of existing healthcare services, which mainly followed up on physical challenges after stroke. Second, cognitive rehabilitation seemed to be less prioritized than other health services, and the established interdisciplinary municipality teams did not seem prepared to follow-up on cognitive issues. Finally, at a professional level, the study reveals the need for building competence in cognitive rehabilitation and having services available in the long run. Conclusion: The study demonstrates the need to increase knowledge concerning cognitive rehabilitation and how rehabilitation trajectories and services should be organized to fulfil stroke survivors' and carers' long-term needs.

Interdisciplinary intervention (GAIN) for adults with post-concussion symptoms: a study protocol for a stepped-wedge cluster randomised trial.

BACKGROUND: Persistent post-concussion symptoms (PCS) are associated with prolonged disability, reduced health-related quality of life and reduced workability. At present, no strong evidence for treatments for people with persistent PCS exists. Our research group developed a novel intervention, "Get going After concussIoN (GAIN)", that incorporates multiple evidence-based strategies including prescribed exercise, cognitive behavioural therapy, and gradual return to activity advice. In a previous randomised trial, GAIN provided in a hospital setting was effective in reducing symptoms in 15-30-year-olds with PCS 2-6 months post-injury. In the current study, we describe the protocol for a trial designed to test the effectiveness of GAIN in a larger municipality setting. Additionally, we test the intervention within a broader age group and evaluate a broader range of outcomes. The primary hypothesis is that participants allocated to enhanced usual care plus GAIN report a higher reduction in PCS 3 months post-intervention compared to participants allocated to enhanced usual care only. METHODS: The study is a stepped-wedge cluster-randomised trial with five clusters. The 8-week interdisciplinary GAIN program will be rolled out to clusters in 3-month intervals. Power calculation yield at least 180 participants to be enrolled. Primary outcome is mean change in PCS measured by the Rivermead Post-Concussion Symptoms Questionnaire from enrolment to 3 months after end of treatment. Secondary outcomes include participation in and satisfaction with everyday activities, labour market attachment and other behavioural measures. Self-reported outcomes are measured at baseline, by end of treatment and at 3, 6, and 18 months after end of treatment. Registry-based outcomes are measured up to 36 months after concussion. DISCUSSION: The trial will provide important information concerning the effectiveness of the GAIN intervention in a municipality setting. Furthermore, it will provide knowledge of possible barriers and facilitators that may be relevant for future implementation of GAIN in different settings. TRIAL REGISTRATION: The current GAIN trial is registered in ClinicalTrials.gov (study identifier: NCT04798885 ) on 20 October 2020.

Stroke-Specific Quality of Life one-year post-stroke in two Scandinavian country-regions with different organisation of rehabilitation services: a prospective study.

PURPOSE: To compare stroke-specific health related quality of life in two country-regions with organisational differences in subacute rehabilitation services, and to reveal whether organisational factors or individual factors impact outcome. MATERIALS AND METHODS: A prospective multicentre study with one-year follow-up of 369 first-ever stroke survivors with ischaemic or haemorrhagic stroke, recruited from stroke units in North Norway (n = 208) and Central Denmark (n = 161). The 12-domain Stroke-Specific Quality of Life scale was the primary outcome-measure. RESULTS: The Norwegian participants were older than the Danish (Mage= 69.8 vs. 66.7 years, respectively), had higher initial stroke severity, and longer stroke unit stays. Both cohorts reported more problems with cognitive, social, and emotional functioning compared to physical functioning. Two scale components were revealed. Between-country differences in the cognitive-social-mental component showed slightly better function in the Norwegian participants. Depression, anxiety, pre-stroke dependency, initial stroke severity, and older age were substantially associated to scale scores. CONCLUSIONS: Successful improvements in one-year functioning in both country-regions may result from optimising long-term rehabilitation services to address cognitive, emotional, and social functioning. Stroke-Specific Quality of Life one-year post-stroke could be explained by individual factors, such as pre-stroke dependency and mental health, rather than differences in the organisation of subacute rehabilitation services.IMPLICATIONS FOR REHABILITATIONThe stroke-specific health related quality of life (SS-QOL) assessment tool captures multidimensional effects of a stroke from the perspective of the patient, which is clinically important information for the rehabilitation services.The cognitive-social-mental component and the physical health component, indicate specific functional problems which may vary across and within countries and regions with different organisation of rehabilitation services.For persons with mild to moderate stroke, longer-term functional improvements may be better optimised if the rehabilitation services particularly address cognitive, emotional, and social functioning.

Validity, reliability and Norwegian adaptation of the Stroke-Specific Quality of Life (SS-QOL) scale.

BACKGROUND: There is a paucity of stroke-specific instruments to assess health-related quality of life in the Norwegian language. The objective was to examine the validity and reliability of a Norwegian version of the 12-domain Stroke-Specific Quality of Life scale. METHODS: A total of 125 stroke survivors were prospectively recruited. Questionnaires were administered at 3 months; 36 test-retests were performed at 12 months post stroke. The translation was conducted according to guidelines. The internal consistency was assessed with Cronbach's alpha; convergent validity, with item-to-subscale correlations; and test-retest, with Spearman's correlations. Scaling validity was explored by calculating both floor and ceiling effects. A priori hypotheses regarding the associations between the Stroke-Specific Quality of Life domain scores and scores of established measures were tested. Standard error of measurement was assessed. RESULTS: The Norwegian version revealed no major changes in back translations. The internal consistency values of the domains were Cronbach's alpha = 0.79-0.93. Rates of missing items were small, and the item-to-subscale correlation coefficients supported convergent validity (0.48-0.87). The observed floor effects were generally small, whereas the ceiling effects had moderate or high values (16%-63%). Test-retest reliability indicated stability in most domains, with Spearman's rho = 0.67-0.94 (all p < 0.001), whereas the rho was 0.35 (p < 0.05) for the 'Vision' domain. Hypothesis testing supported the construct validity of the scale. Standard error of measurement values for each domain were generated to indicate the required magnitudes of detectable change. CONCLUSIONS: The Norwegian version of the Stroke-Specific Quality of Life scale is a reliable and valid instrument with good psychometric properties. It is suited for use in health research as well as in individual assessments of persons with stroke.

Rupture of a non-traumatic anterior communicating artery aneurysm: Does location of aneurysm associate with functional independence following post-acute in-patient neurorehabilitation?

OBJECTIVE: Patients with non-traumatic rupture of an aneurysm located at the anterior communicating artery (ACoA) often experience cognitive disabilities. It is unknown whether location of aneurysm also affects the possibility for improvement in functional independence compared to patients with an aneurysmal subarachnoid hemorrhage (a-SAH) located elsewhere. The aim was to explore the association between location of aneurysm (ACoA versus other) and level of functional independence, measured by Functional Independence Measure (FIM), at discharge from rehabilitation. Additionally, age and FIM at admission were explored. METHOD: Historical cohort study among 107 patients with a-SAH based on data from a clinical database and a population-based register. Data were analyzed using multivariable logistic regression. RESULTS: Patients with ACoA were admitted with poorer cognitive FIM (median 6 (IQR 5-14) compared to patients with aneurysms located elsewhere (median 12 (IQR 6-23) (p = 0.0129); no difference at discharge. No association between aneurysm location and functional independence was observed. Higher age was associated with poorer outcome in bowel management OR 0.54 (95% CI 0.31-0.92), bladder management OR 0.59 (95% CI 0.35-0.98), comprehension OR 0.53 (95% CI 0.30-0.94), and memory OR 0.48 (95% CI 0.25-0.93). Overall, FIM at admission was associated with functional independence at discharge with the exception of stair walking and bladder management which did not reach statistical significance. CONCLUSION: ACoA was not associated with poorer level of functional independence compared to patients with a-SAH located elsewhere. Higher age was associated with poorer outcome in continence, comprehension, and memory, whereas higher FIM was associated with better functional independence across items at discharge.
