Associations between pre-stroke physical activity and physical quality of life three months after stroke in patients with mild disability. PLoS One 2022; 17:e0266318. [PMID: 35767520 PMCID: PMC9242505 DOI: 10.1371/journal.pone.0266318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Accepted: 03/18/2022] [Indexed: 11/19/2022] Open
Abstract
Background
Much is known about the association between physical activity and the occurrence of stroke. However, the evidence about the correlation between pre-stroke physical activity and post-stroke quality of life remains inconsistent. Thus, there is a high public health relevance to the topic.
Aim
The aim of this study was to investigate the association between pre-stroke physical activity and physical quality of life after three months.
Methods
Data arises from 858 patients with stroke included a prospective single-centre observational cohort study in Augsburg, Germany, between September 2018 and November 2019. The participants were recruited at the Department of Neurology and Clinical Neurophysiology, University Hospital of Augsburg after their stroke event. The level of physical activity was determined following the short form of the International Physical Activity Questionnaire at baseline. Physical quality of life was assessed three months after hospital discharge using the German version of the Stroke Impact Scale (SIS). A multiple linear regression model and a quantile regression were carried out.
Results
A total of 497 patients were included in the analysis (mean age 69.6, 58.8% male), 26.2% had a high, 18.9% a moderate and 54.9% a low level of pre-stroke physical activity. Patients with high pre-stroke physical activity had a significantly better physical quality of life three months after stroke in the SIS physical domain (beta = 4.1) and in the SIS subdomains hand function (beta = 5.6), mobility (beta = 4.1) and activities of daily living (beta = 3.7). In the physical domain and the subdomain mobility, the effect was especially strong for persons with low physical quality of life after three months.
Conclusion
Pre-stroke physical activity seems to have an important and positive association with physical quality of life after three months in patients with mild disability. Further studies are needed to confirm these results.

Results From the Stroke Cohort Study Augsburg. Front Neurol 2022; 13:852486. [PMID: 35359631 PMCID: PMC8964017 DOI: 10.3389/fneur.2022.852486] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Accepted: 02/16/2022] [Indexed: 11/13/2022] Open
Abstract
Background Post-stroke fatigue is a common symptom after stroke. However, studies on the factors associated with early and late fatigue are scarce. The objective of this study was to identify variables associated with early and late fatigue. Methods In the German Stroke Cohort Augsburg (SCHANA) study, participants were interviewed during their hospital stay and completed a postal questionnaire 3 and 12 months post-stroke. Fatigue was assessed using the Fatigue Assessement Scale (FAS). In addition, depression was measured by the Patient Health Questionnaire (PHQ-9), general health status by the EQ-5D visual analog scale, and physical activity by the International Physical Activity Questionnaire (IPAQ). Multivariable regression models were used to determine the associations between FAS scores at 3 and 12 months post-stroke and demographic, psychosocial and health-related covariables. Results Among 505 participants, the frequency of fatigue was 31.1% 3 months and 29.1% 12 months post-stroke. Prior stroke (ß = 2.37, p = 0.0076), prior diagnosis of depression (ß = 5.04, p = 0.0001), higher NIHSS (ß = 0.25, p = 0.0360) and higher PHQ-9 scores (ß = 0.55, p < 0.0001) were significantly associated with higher fatigue levels 3 months post-stroke. Additionally, younger age (ß = -0.07, p = 0.0219), a worse rating of general health at baseline (ß = -0.04, p = 0.0287) and low pre-stroke physical activity (ß = -0.0004, p = 0.0089) were significantly associated with higher fatigue levels 12 months after stroke. Conclusions Fatigue is a common and persisting symptom even in patients with mild impairment. Prior depressive disorder and early depressive symptoms were the most relevant predictors of both early and late fatigue.

Abstract
This chapter is written for the qualified neurologist or related professional working with persons who have had a stroke or other sudden brain injury. It is critical that the presence of aphasia is detected, no matter how mild the presentation, and to support that assertion, this chapter highlights the plight of persons with latent aphasia. At the individual level, the impact of aphasia is devastating, with overwhelming evidence that aphasia negatively impacts psychosocial outcomes. At the global level, sensitive detection and accurate diagnosis of aphasia are critical for accurate characterization and quantification of the global burden of aphasia. The word "LANGUAGE" is leveraged as an acronym to create a useful and memorable checklist to guide navigation of aphasia screening and assessment: it begins with the definition of language (L), followed by the definition and diagnostic criteria for aphasia (A). Then language abilities and characteristics to be considered in assessment are presented: naming (N); grammar and syntax (G); unintelligible words, jargon, and paraphasias (U); auditory comprehension and repetition (A); graphemic abilities-reading and writing (G); and everyday communication and discourse (E). Recommendations for improving procedural adherence are provided, and a list of potential brief assessment measures are introduced.

Abstract
OBJECTIVES (1) To assess the effects of a conventional, delayed physiotherapy protocol used by Ischemic Stroke (IS) and Hemorrhagic Stroke (HS) post-stroke patients, in their electromyographic activation patterns during hemiparetic gait; and (2) to study whether this protocol may improve the functional abilities in this population. METHODS This is an observational, descriptive, and analytical quasi-experimental trial. Forty patients with unilateral IS ( n = 25 ) and HS ( n = 15 ) stroke were recruited; the stroke involved the motor cortex or sub-cortical areas, and the patients were able to walk independently. Interventions with standard protocols of physiotherapy were carried out. Evaluations (clinical and gait assessment) were performed at the time of admission and at the end of the protocol. Outcome measures include Stroke Impact Scale, Timed Up and Go Test, and gait electromyographic evaluation. RESULTS Only IS patients (with an average of 124 . 4 ± 45 . 4 months delayed access to physiotherapy rehabilitation) had improvements in Timed Up and Go Test (change in speed =- 8 . 0 seg p < 0 . 05 ) and presented an anticipation of the onset in Upper leg muscles after the intervention. BF ( p = 0 . 05 ), ST ( p = 0 . 001 ), and RF ( p = 0 . 024 ), started their recruitment (onset) earlier at the swing phase of the gait cycle, which is more similar to the normal pattern (grey shadow). IS and HS ( 120 . 4 ± 28 . 4 months since last stroke) patients presented higher electromyographic activation, after physiotherapy, of the posterior leg muscles (gastrocnemius, semitendinosus and biceps femoris) during stance phase ( p < 0 . 05 ). CONCLUSION IS patients had improvements after delayed conventional physiotherapy. For HS limited response to intervention was observed.

Abstract
Background: Brain plasticity is an intrinsic property of the nervous system, which is modified during its lifetime. This is one mechanism of recuperation after injuries with an important role in rehabilitation. Evidence suggests that injuries in the nervous system disturb the stability between inhibition and excitability essential for the recuperation process of neuroplasticity. However, the mechanisms involved in this balance are not completely understood and, besides the advancement in the field, the knowledge has had a low impact on the rehabilitation practice. Therefore, the understanding of the relationship between biomarkers and functional disability may help to optimize and individualize treatments and build consistent studies in the future. Methods: This cohort study, the deficit of inhibition as a marker of neuroplasticity study, will follow four groups (stroke, spinal cord injury, limb amputation, and osteoarthritis) to understand the neuroplasticity mechanisms involved in motor rehabilitation. We will recruit 500 subjects (including 100 age- and sex-matched controls). A battery of neurophysiological assessments, transcranial magnetic stimulation, electroencephalography, functional near-infrared spectroscopy, and magnetic resonance imaging, is going to be used to assess plasticity on the motor cortex before and after rehabilitation. One of the main hypotheses in this cohort is that the level of intracortical inhibition is related to functional deficits. We expect to develop a better understanding of the neuroplasticity mechanisms involved in the rehabilitation, and we expect to build neurophysiological “transdiagnostic” biomarkers, especially the markers of inhibition, which will have great relevance in the scientific and therapeutic improvement in rehabilitation. The relationship between neurophysiological and clinical outcomes will be analyzed using linear and logistic regression models. Discussion: By evaluating the reliability of electroencephalography, functional near-infrared spectroscopy, transcranial magnetic stimulation, and magnetic resonance imaging measures as possible biomarkers for neurologic rehabilitation in different neurologic disorders, this study will aid in the understanding of brain plasticity mechanisms in rehabilitation, allowing more effective approaches and screening methods to take place.

Abstract
Upper limb motor impairments, such as muscle weakness, loss of dexterous movement, and reduced sensation, are common after a stroke. The extent and severity of these impairments differ among individuals, depending on the anatomical location and size of lesions. Identifying impairments specific to the individual is critical to optimize their functional recovery. The upper limb Physiological Profile Assessment (PPA) provides quantitative measures of key physiological domains required for adequate function in the upper limbs. The present study investigates the use of the upper limb PPA in a chronic stroke population. Fifty participants with chronic stroke completed all tests of the upper limb PPA with both their affected and less affected upper limbs. Performance in each test was compared to that of 50 age- and sex-matched control subjects with no history of a stroke. Correlations between test performance and validated measures of stroke, sensorimotor function, and disability were examined. Compared with control subjects, people with stroke demonstrated substantially impaired upper limb PPA performance for both their affected and less affected limbs. Performance in the upper limb PPA was associated with validated measures of sensorimotor function specific to the stroke population (Fugl-Meyer Assessment) and stroke-related disability (Stroke Impact Scale). The upper limb PPA shows good concurrent validity as a means to quantify upper limb function in a chronic stroke population. These tests identify domain-specific deficits and could be further tailored to an individual patient by the clinician to inform rehabilitation and track recovery.NEW & NOTEWORTHY Upper limb motor impairment is a common manifestation after stroke, compromising independence in fundamental daily activities involving the ability to reach, grasp, and manipulate objects. The upper limb Physiological Profile Assessment (PPA) offers a means of quantifying performance of the individual sensorimotor domains that are essential for upper limb function. Establishing individual performance profiles based on age- and sex-based normative scores may facilitate individualized treatment decisions by identifying the stroke patient's specific strengths and limitations.

Abstract
BACKGROUND It is important for clinicians to have a better understanding of stroke survivor's goals. Important performance analysis (IPA) is a tool that could be utilized to identify goal priorities in rehabilitation. OBJECTIVES To examine the utility of the IPA method to identify goal priorities in a diverse group of community dwelling stroke survivors. METHODS Thirty-eight stroke survivors completed private structured interviews and were asked to rate their perceived importance and performance of 37 goal areas. Important-performance analysis (IPA) was utilized to determine goal priorities for the overall sample. Different IPA methods used to identify goal priorities were compared. Goal priorities were also compared by age (dichotomized as <65 and ≥65 years) and sex (male or female). RESULTS The IPA method effectively separated the goals into the four quadrants, and distinguished which goals were a priority for the sample of stroke survivors. The five goals that were consistently identified as a focus area were: hand function, driving, balance, memory, and arm strength. Men rated mood control as more important than women (p = .046). The two goals rated as being more important for those older than 65 were home accessibility (p = .008) and skin health (p < .001). CONCLUSIONS Stroke survivors continue to have goals related to their stroke recovery in the years after their stroke. Both current performance as well as perceived importance should be considered during goal discussions with stroke survivors. IPA can help identify goal priorities in this population.

Abstract
PURPOSE Optimal community reintegration is a key rehabilitation outcome post-stroke. This concept has been investigated in many countries but not qualitatively in New Zealand. We explored perceptions about community reintegration of stroke survivors living in southern New Zealand. METHOD Qualitative interviews were used to collect data. Recruitment was via local stroke clubs, inviting adult stroke survivors (stroke duration > six months, any severity or type) living in the lower South Island. Data were analysed using the General Inductive Approach. RESULTS Eight stroke survivors (two female, six males; age range 50-80 years, mean 66 years (SD = 12); mean time since stroke 6.5 (SD = 4) years) participated. Participants' perceptions of what is integral to reintegration into their community were shaped by four themes, namely: (1) personal relationships, (2) re-establishing normality (old and new), (3) purpose in life, and (4) independence. CONCLUSIONS Stroke survivors in New Zealand hold many similar perceptions about optimal community reintegration with those living elsewhere. Key to successful community reintegration, irrespective of geography, culture and ethnicity, appears to be involvement in meaningful activities, and reduced reliance on others whilst maintaining or developing good social relationships. These fundamental components are then contextually nuanced by what is meaningful and important to the individual.IMPLICATIONS FOR REHABILITATIONOptimal community reintegration post-stroke is arguably the key goal of rehabilitation, and thus should be enabled and measured.To optimise community reintegration post-stroke, rehabilitation should focus on enabling stroke survivors' social relationships, independent community mobility, and engagement in meaningful activities.Optimal community reintegration post-stroke is however contextual. Rehabilitation professionals must understand what each patient considers successful community reintegration to be for them and tailor their rehabilitation accordingly.

Abstract
BACKGROUND Peer support groups can be a way to obtain support, problem solve, and widen social networks. However, there has been no systematic literature review examining the evidence for the use of peer support groups after an acquired brain injury (ABI). OBJECTIVE This review sought to systematically evaluate the evidence for (1) the psychosocial effectiveness, and (2) the experience of peer support groups in adults who had experienced ABI's. METHODS The systematic literature search was conducted across the following four databases: PsycINFO, PsycARTICLES, MEDLINE, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) in October 2019. The mixed methods appraisal tool was used to examine the quality of the research. RESULTS 13 papers were included in this review. Limited evidence was found for the psychosocial effectiveness of peer support groups in ABI, although the experience of partaking in a peer support group was largely found to be positive. The benefits and helping factors of taking part in a peer support group can be summarized as: being connected, interacting with others, and providing and receiving support. CONCLUSIONS The findings of this review suggest that peer support groups could be a promising intervention to support individuals and promote adjustment following an ABI.

Abstract
Cognitive difficulties can be subtle and only come to light when patients return home from inpatient care and start to participate in society. Subjective cognitive complaints often interfere with participation, hence capturing cognitive complaints systematically is important. We developed a patient- and relative-reported measure to assess cognitive complaints during daily life activities across the memory, attention and executive domain for patients with acquired brain injury (ABI). The inventory Cognitive Complaints - Participation (CoCo-P) was created based on a literature review, consultations with experts, semi-structured interviews with patients, and a quantitative study. The inventory was administered to patients with ABI (n = 46), their relatives (n = 33) and healthy controls (n = 102) to finalize the inventory. We examined the reported complaints per daily life activity and cognitive domain of patients and healthy controls, and we compared the patients' and relatives' reports. The majority of patients (87-96%) experienced cognitive complaints, mostly related to attention, at work/education, during leisure activities, and in contact with family/friends and community. Patients reported more cognitive complaints than relatives. The CoCo-P seems appropriate to capture cognitive complaints in daily life in patients with mild ABI. Additional research is needed in terms of reliability and validity.

IMPORTANCE A gap in care for stroke survivors exists at the point of transition from inpatient rehabilitation to home, when survivors encounter new environmental barriers because of the cognitive and sensorimotor sequelae of stroke. Resolving these barriers and improving independence in the community have the potential to significantly improve stroke survivors' long-term morbidity. OBJECTIVE To investigate the efficacy and safety of a novel enhanced rehabilitation transition program to reduce environmental barriers and improve daily activity performance and community participation among stroke survivors. DESIGN, SETTING, AND PARTICIPANTS This is a phase 2b, single-blind, parallel-group, randomized clinical trial. Participants will be randomized using a 1:1 allocation ratio, stratified by Functional Independence Measure and age, to either attentional control or the intervention. Community Participation Transition After Stroke (COMPASS) is a complex intervention that uses 2 complementary evidence-based interventions: home modifications and strategy training delivered in the home. Community participation after stroke, measured by the Reintegration to Normal Living Index, is the primary outcome. Secondary outcomes include quality of life after stroke, measured by the Stroke Impact Scale, and daily activity performance and magnitude of environmental barriers in the home, both measured by the In-Home Occupational Performance Evaluation. An intention-to-treat analysis will be used. A total of 180 participants, who are 50 years or older, were independent in activities of daily living prior to stroke, and are undergoing inpatient rehabilitation following stroke with a plan to be discharged home, will be included in the study. DISCUSSION Stroke is a leading cause of serious long-term disability in the United States. The COMPASS study is ongoing. To date, 99 participants have been recruited and 77 randomized, with 37 in the treatment group and 40 in the control group. Resumption of previous activities immediately after discharge can improve immediate and long-term community participation. Results from this study will fill a critical gap in stroke rehabilitation evidence by providing important information about the long-term community participation and daily activity performance among stroke survivors as well as environmental barriers in their homes.

Johansson GM, Häger CK. A modified standardized nine hole peg test for valid and reliable kinematic assessment of dexterity post-stroke. J Neuroeng Rehabil 2019; 16:8. [PMID: 30642350 PMCID: PMC6332630 DOI: 10.1186/s12984-019-0479-y] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Accepted: 01/02/2019] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Impairments in dexterity after stroke are commonly assessed by the Nine Hole Peg Test (NHPT), where the only outcome variable is the time taken to complete the test. We aimed to kinematically quantify and to compare the motor performance of the NHPT in persons post-stroke and controls (discriminant validity), to compare kinematics to clinical assessments of upper extremity function (convergent validity), and to establish the within-session reliability. METHODS The NHPT was modified and standardized (S-NHPT) by 1) replacing the original peg container with an additional identical nine hole pegboard, 2) adding a specific order of which peg to pick, and 3) specifying to insert the peg taken from the original pegboard into the corresponding hole of the target pegboard. Eight optical cameras registered upper body kinematics of 30 persons post-stroke and 41 controls during the S-NHPT. Four sequential phases of the task were identified and analyzed for kinematic group differences. Clinical assessments were performed. RESULTS The stroke group performed the S-NHPT slower (total movement time; mean diff 9.8 s, SE diff 1.4), less smoothly (number of movement units; mean diff 0.4, SE diff 0.1) and less efficiently (path ratio; mean diff 0.05, SE diff 0.02), and used increased scapular/trunk movements (acromion displacement; mean diff 15.7 mm, SE diff 3.5) than controls (P < 0.000, r ≥ 0.32), indicating discriminant validity. The stroke group also spent a significantly longer time grasping and releasing pegs relative to the transfer phases of the task compared to controls. Within the stroke group, kinematics correlated with time to complete the S-NHPT and the Fugl-Meyer Assessment (rs 0.38-0.70), suggesting convergent validity. Within-session reliability for the S-NHPT was generally high to very high for both groups (ICCs 0.71-0.94). CONCLUSIONS The S-NHPT shows adequate discriminant validity, convergent validity and within-session reliability. Standardization of the test facilitates kinematic analysis of movement performance, which in turn enables identification of differences in movement control between persons post-stroke and controls that may otherwise not be captured through the traditional time-based NHPT. Future research should ascertain further psychometric properties, e.g. sensitivity, of the S-NHPT.

Abstract
BACKGROUND Virtual reality-based training has found increasing use in neurorehabilitation to improve upper limb training and facilitate motor recovery. OBJECTIVE The aim of this study was to directly compare virtual reality-based training with conventional therapy. METHODS In a multi-center, parallel-group randomized controlled trial, patients at least 6 months after stroke onset were allocated either to an experimental group (virtual reality-based training) or a control group receiving conventional therapy (16x45 minutes within 4 weeks). The virtual reality-based training system replicated patients´ upper limb movements in real-time to manipulate virtual objects. Blinded assessors tested patients twice before, once during, and twice after the intervention up to 2-month follow-up for dexterity (primary outcome: Box and Block Test), bimanual upper limb function (Chedoke-McMaster Arm and Hand Activity Inventory), and subjective perceived changes (Stroke Impact Scale). RESULTS 54 eligible patients (70 screened) participated (15 females, mean age 61.3 years, range 20-81 years, time since stroke 3.0±SD 3 years). 22 patients were allocated to the experimental group and 32 to the control group (3 drop-outs). Patients in the experimental and control group improved: Box and Block Test mean 21.5±SD 16 baseline to mean 24.1±SD 17 follow-up; Chedoke-McMaster Arm and Hand Activity Inventory mean 66.0±SD 21 baseline to mean 70.2±SD 19 follow-up. An intention-to-treat analysis found no between-group differences. CONCLUSIONS Patients in the experimental and control group showed similar effects, with most improvements occurring in the first two weeks and persisting until the end of the two-month follow-up period. The study population had moderate to severely impaired motor function at entry (Box and Block Test mean 21.5±SD 16). Patients, who were less impaired (Box and Block Test range 18 to 72) showed higher improvements in favor of the experimental group. This result could suggest that virtual reality-based training might be more applicable for such patients than for more severely impaired patients. TRIAL REGISTRATION ClinicalTrials.gov NCT01774669.

Abstract
PURPOSE To examine if the International Classification of Functioning (ICF) core set for stoke contains problems that are relevant for the persons living with stroke as expressed in the Stroke Impact Scale (SIS). METHODS Cross-sectional study of 242 persons with previous stroke. The agreement between the perceived problems in the SIS items and problems in the categories of Comprehensive ICF Core Set for stroke were analyzed using percent of agreement and Kappa statistic. RESULTS The analyses between 57 items of the SIS and 31 second-level categories of the ICF were conducted. The problems in domains of "Mobility", "Activities of daily living", "Hand function", "Strength" in the SIS had moderate agreement when compared to ICF categories. The SIS domains of "Emotion" and "Communication", as well as some aspects of the "Memory" had slight or fair agreement with corresponding ICF categories. The results of the study suggest that there is acceptable agreement between persons after stroke and health professionals in the physical aspects, but rather poor agreement in the cognitive and emotional aspects of functioning. CONCLUSIONS Health professionals do not fully capture the magnitude of emotional or social problems experienced by persons after stroke when using the ICF Core Set as a framework for evaluation. Implications for Rehabilitation The ICF Core Set for Stroke provides comprehensive list of possible health and health related outcomes for persons after stroke. Problems reported in condition-specific patient-reported outcome scales can be important in decision making in rehabilitation. Patients and health professionals tend to agree more on physical than cognitive problems. Examination of the relevance of the ICF cores set for stroke by comparing with the Stroke Impact Scale.

Abstract
Introduction Stroke is a leading cause of serious, long-term disability in the US. With shorter inpatient hospital stays, more time in rehabilitation is devoted to medical stabilization and less on skills to regain independence in daily activities. The transition home may be an opportunity for intervention focused on regaining independence. We propose an enhanced rehabilitation transition program called: Community Participation Transition after Stroke (COMPASS). Method A prospective, randomized, single-blinded, parallel-group pilot study was completed to demonstrate feasibility with N=15 participants. Findings Fidelity to the protocol was achieved: the COMPASS group received 81% of the planned minutes and 83% of the intervention visits. There was no difference between groups for healthcare utilization or falls. Adherence was 85% at 3-months and 71% at 9-months for the home modification intervention. At 6-months, the COMPASS group's reintegration to normal living scores improved by 17.39 points for the COMPASS group, and 1.30 for the control group. Environmental barriers decreased in both groups. Conclusion This pilot study demonstrated that it is feasible to implement a community participation intervention during the period of transitioning home from inpatient rehabilitation for stroke survivors. Additional studies are necessary to determine the efficacy of the intervention.

Abstract
This article compares the structure and process of rehabilitation for stroke patients at 2 internationally recognized rehabilitation hospitals, Klinik Valens (“Valens”) in Switzerland and the William Donald Schaeffer Rehabilitation Hospital at Kernan (“Kernan”) in the United States. Although the patient mix, structure, and process of rehabilitation were similar in many regards, there were some important differences. Most notably, on average, patients at the U.S. hospital were discharged from rehabilitation at approximately the same day poststroke that rehabilitation began in Switzerland. Patients remained in an inpatient setting an average of 40 days longer in Switzerland (for the combination of acute care and rehabilitation) and had significantly higher levels of functioning at discharge when compared to their U.S. counterparts. The authors’ findings suggest that Europe may offer opportunities for rehabilitation research that would be difficult to duplicate in the United States and highlight policy-relevant questions for future studies aimed at developing efficient managed care systems for stroke survivors.

Abstract
Poststroke motor control is characterized by greatly reduced muscle power generation. To date, the extent to which muscle power limits walking performance or whether its remediation should be a primary component of locomotor rehabilitation has yet to be established. The purpose of this study was to examine the feasibility and the effects of Poststroke Optimization of Walking using Explosive Resistance training, an intervention aimed at improving poststroke muscular and locomotor function. Twelve subjects (6-60 mo poststroke) participated in 24 training sessions (3 sessions/wk for 8 wk). Exercises included leg press, calf raises, and jump training, all performed at high concentric velocity, as well as trials of fast walking. We measured self-selected and fastest comfortable walking speeds as well as knee extensor and plantar flexor strength and power at pretraining, posttraining, and 8 wk follow-up time points. In addition, we also performed a number of clinical assessments commonly used in poststroke rehabilitation trials. Following training, significant improvements in lower-limb muscle strength and power were realized and accompanied by improvements in self-selected as well as fastest comfortable walking speeds. No changes in clinical assessments resulted from training.

Abstract
BACKGROUND Rural living has been demonstrated to have an effect on a person's overall health status, and rural residing individuals often have decreased access to health and specialized rehabilitation services. AIM The aim of this study was to determine if there are differences in recovery from stroke between urban and rural-dwelling stroke survivors accessing an in-home, community-based, interdisciplinary, stroke rehabilitation program. METHODS Data from a cohort of 1222 stroke survivors receiving care from the Community Stroke Rehabilitation Teams between January 2009 and June 2013 was analyzed. This program delivers stroke rehabilitation care directly in a person's home and community. Functional and psychosocial outcomes were evaluated at baseline, discharge, and six -month follow-up. A series of multiple linear regression analyses was performed to determine if rural versus urban status was a significant predictor of discharge and 6-month health outcomes. RESULTS The mean age of the rural cohort was 68.8 (±13.1) years (53.6% male), and the urban cohort was 68.4 (±13.0) years (44.8% male). A total of 278 (35.4%) individuals were classified as living in a rural area using the Rurality Index for Ontario. In multivariate linear regression analysis, no significant differences on the Functional Independence Measure, the Stroke Impact Scale, the Hospital Anxiety and Depression Scale, or the Reintegration to Normal Living Index were found between urban and rural cohorts. CONCLUSIONS When provided with access to a home-based, specialized stroke rehabilitation program, rural dwelling stroke survivors make and maintain functional gains comparable to their urban-living counterparts.

Abstract
Purpose: Upper limb disability following stroke may have multiple effects on the individual. Existing assessment instruments tend to focus on impairment and function and may miss other changes that are personally important. This study aimed to identify personally significant impacts of upper limb disability following stroke. Methods: Accounts by stroke survivors, in the form of web-based diaries (blogs) and stories, were sought using a blog search engine and in stroke-related web-sites. Thematic analysis using the World Health Organisation’s International Classification of Functioning Disability and Health (ICF) was used to identify personal impacts of upper limb disability following stroke. Results: Ninety-nine sources from at least four countries were analysed. Many impacts were classifiable using the ICF, but a number of additional themes emerged, including emotional, cognitive and behavioural changes. Blogs and other web-based accounts were easily accessible and rich sources of data, although using them raised several methodological issues, including potential sample bias. Conclusions: A range of impacts was identified, some of which (such as use of information technology and alienation from the upper limb) are not addressed in current assessment instruments. They should be considered in post-stroke assessments. Blogs may help in the development of more comprehensive assessments.Implications for Rehabilitation A comprehensive assessment of the upper limb following stroke should include the impact of upper limb problems on social participation, as well as associated emotional, cognitive and behavioural changes. Using personalised assessment instruments alongside standardised measures may help ensure that these broader domains are considered in discussions between clinicians and patients. Rehabilitation researchers should investigate whether and how these domains could be addressed and operationalised in standard upper limb assessment instruments.

Abstract
We examined the benefit of tissue plasminogen activator (tPA), delivered as part of usual stroke management, on patient-reported outcomes and health care utilization. Using a case control design, patients who received tPA as part of usual stroke management were compared with patients who would have received tPA had they arrived to the hospital within the therapeutic time window. Data were collected from surveys 6 months after stroke using standardized patient-reported outcome measures and questions about health care utilization. Demographic and medical data were acquired from hospital records. Patients were matched on stroke severity, age, race, and gender. Matching was done with 1:2 ratio of tPA to controls. Results were compared between groups with 1-tailed tests because of a directionally specific hypothesis in favor of the tPA group. The tPA (n = 78) and control (n = 156) groups were matched across variables, except for stroke severity, which was better in the control group; subsequent analyses controlled for this mismatch. The tPA group reported better physical function, communication, cognitive ability, depressive symptomatology, and quality of life/participation compared with the control group. Fewer people in the tPA group reported skilled nursing facility stays, emergency department visits, and rehospitalizations after their stroke compared with controls. Reports of other postacute services were not different between groups. Although it is known that tPA reduces disability, this is the first study to demonstrate the effectiveness of tPA in improving meaningful, patient-reported outcomes. Thus, use of tPA provides a large benefit to the daily lives of people with ischemic stroke.

Abstract
Background In recent years, virtual reality has been introduced to neurorehabilitation, in particular with the intention of improving upper-limb training options and facilitating motor function recovery. Methods/Design The proposed study incorporates a quantitative part and a qualitative part, termed a mixed-methods approach: (1) a quantitative investigation of the efficacy of virtual reality training compared to conventional therapy in upper-limb motor function are investigated, (2a) a qualitative investigation of patients’ experiences and expectations of virtual reality training and (2b) a qualitative investigation of therapists’ experiences using the virtual reality training system in the therapy setting. At three participating clinics, 60 patients at least 6 months after stroke onset will be randomly allocated to an experimental virtual reality group (EG) or to a control group that will receive conventional physiotherapy or occupational therapy (16 sessions, 45 minutes each, over the course of 4 weeks). Using custom data gloves, patients’ finger and arm movements will be displayed in real time on a monitor, and they will move and manipulate objects in various virtual environments. A blinded assessor will test patients’ motor and cognitive performance twice before, once during, and twice after the 4-week intervention. The primary outcome measure is the Box and Block Test. Secondary outcome measures are the Chedoke-McMaster Stroke Assessments (hand, arm and shoulder pain subscales), the Chedoke-McMaster Arm and Hand Activity Inventory, the Line Bisection Test, the Stroke Impact Scale, the MiniMentalState Examination and the Extended Barthel Index. Semistructured face-to-face interviews will be conducted with patients in the EG after intervention finalization with a focus on the patients’ expectations and experiences regarding the virtual reality training. Therapists’ perspectives on virtual reality training will be reviewed in three focus groups comprising four to six occupational therapists and physiotherapists. Discussion The interviews will help to gain a deeper understanding of the phenomena under investigation to provide sound recommendations for the implementation of the virtual reality training system for routine use in neurorehabilitation complementing the quantitative clinical assessments.

The incidence of stroke in younger individuals is rising, producing unique challenges due to loss of productive roles and long-term impact in the survivor's life. This paper reports the results of a hospital-based program based on occupational therapy principles that was designed to provide support and education for 13 younger individuals (<65) with stroke. Participants demonstrated improved socialization, healthy coping, and role attainment as measured by the Stroke Impact Scale (SIS), the Community Integration Questionnaire (CIQ), and a member satisfaction questionnaire. Key factors for successful implementation and considerations for future programs to meet the needs of younger adults with stroke are discussed.

Abstract
Neurological rehabilitation involving motor training has resulted in clinically meaningful improvements in function but is unable to eliminate many of the impairments associated with neurological injury. Thus there is a growing need for interventions that facilitate motor learning during rehabilitation therapy, to optimize recovery. d-Cycloserine (DCS), a partial N-methyl-d-aspartate (NMDA) receptor agonist that enhances neurotransmission throughout the central nervous system (Ressler KJ, Rothbaum BO, Tannenbaum L, Anderson P, Graap K, Zimand E, Hodges L, Davis M. Arch Gen Psychiatry 61: 1136-1144, 2004), has been shown to facilitate declarative and emotional learning. We therefore tested whether combining DCS with motor training facilitates motor learning after stroke in a series of two experiments. Forty-one healthy adults participated in experiment I, and twenty adults with stroke participated in experiment II of this two-session, double-blind study. Session one consisted of baseline assessment, subject randomization, and oral administration of DCS or placebo (250 mg). Subjects then participated in training on a balancing task, a simulated feeding task, and a cognitive task. Subjects returned 1-3 days later for posttest assessment. We found that all subjects had improved performance from pretest to posttest on the balancing task, the simulated feeding task, and the cognitive task. Subjects who were given DCS before motor training, however, did not show enhanced learning on the balancing task, the simulated feeding task, or the associative recognition task compared with subjects given placebo. Moreover, training on the balancing task did not generalize to a similar, untrained balance task. Our findings suggest that DCS does not enhance motor learning or motor skill generalization in neurologically intact adults or in adults with stroke.

Abstract
BACKGROUND Arm paresis remains a major impairment after stroke despite the best conventional rehabilitation. Randomized, controlled trials of intensive exercise programs have demonstrated improvements in arm function for patients with chronic stroke. However, the gains achieved have been relatively modest for the large investments in patient and therapist time. OBJECTIVE To evaluate the safety, acceptance, adherence, and effectiveness of a community-based exercise program for upper limb paresis in patients with chronic stroke and the effects of telerehabilitation monitoring in kiosks distributed through the community. METHODS Longitudinal cohort with geographic control group. The experimental group received devices needed for a home exercise program based on the Carr and Shepherd "Motor Learning Program" and were instructed to practice the exercises at least twice a week at the kiosk and at least 3 more days a week at home. The control group received usual care. RESULTS Compared with the control group, patients in the experimental group demonstrated significant gains in arm function as measured by the Wolf Motor Function Test, 9-Hole Peg Test, Motricity Index, and Nottingham Extended Activities of Daily Living Questionnaire. The intervention received high satisfaction ratings and produced no adverse events. Only 30% of the subjects attended kiosks regularly. Outcomes for this group did not differ significantly from those who only practiced at home. CONCLUSIONS Home- and community-based exercise for arm paresis is safe and effective. Telerehabilitation interventions will need additional enhancements to improve effectiveness. The optimal upper extremity exercise prescription poststroke remains to be established.

Abstract
PURPOSE To summarize the existing literature examining constraint-induced movement therapy (CIMT), relative to dose-matched control interventions, for upper-limb (UL) dysfunction in adult survivors of stroke. METHODS CINAHL, Cochrane Library, Embase, NARIC/CIRRIE-Rehabdata, PEDro, PubMed, Scopus, and Web of Science were searched from their inception to February 2011. Trial quality was described using the PEDro scale. The findings were summarized with meta-analysis. RESULTS For the 22 trials identified, the mean (SD) PEDro score was 6.4 (1.2). Meta-analysis showed CIMT to be superior to dose-matched interventions based on indicators of UL motor capacity (15 trials, n=432; standardized mean difference [SMD]=0.47, 95% CI, 0.27-0.66) and UL ability (14 trials, n=352; SMD=0.80, 95% CI, 0.57-1.02); Functional Independence Measure scores (6 trials, n=182; mean difference [MD]=5.05, 95% CI, 2.23-7.87); and Motor Activity Log scores (Amount of Use: 12 trials, n=318; MD=1.05, 95% CI, 0.85-1.24; Quality of Movement: 11 trials, n=330; MD=0.89, 95% CI, 0.69-1.08). CONCLUSIONS Compared to control interventions of equal duration and dose, CIMT produced greater improvements in a variety of indicators of UL function in adult survivors of a stroke with residual movement of their upper limb.

Abstract
BACKGROUND Although task-specific training is emerging as a viable approach for recovering motor function after stroke, there is little evidence for whether the effects of such training transfer to other functional motor tasks not directly practiced in therapy. OBJECTIVE The purpose of the current study was to test whether training on one motor task in individuals with chronic hemiparesis poststroke would transfer to untrained tasks that were either spatiotemporally similar or different. METHODS In all, 11 participants with chronic mild to moderate hemiparesis following stroke completed 5 days of supervised massed practice of a feeding task with their affected side. Performance on the feeding task, along with 2 other untrained functional upper-extremity motor tasks (sorting, dressing) was assessed before and after training. RESULTS Performance of all 3 tasks improved significantly after training exclusively on 1 motor task. The amount of improvement in the untrained tasks was comparable and was not dependent on the degree of similarity to the trained task. CONCLUSIONS Because the number and type of tasks that can be practiced are often limited within standard stroke rehabilitation, results from this study will be useful for designing task-specific training plans to maximize therapy benefits.

Abstract
BACKGROUND Residual disability after stroke is substantial; 65% of patients at 6 months are unable to incorporate the impaired upper extremity into daily activities. Task-oriented training programs are rapidly being adopted into clinical practice. In the absence of any consensus on the essential elements or dose of task-specific training, an urgent need exists for a well-designed trial to determine the effectiveness of a specific multidimensional task-based program governed by a comprehensive set of evidence-based principles. The Interdisciplinary Comprehensive Arm Rehabilitation Evaluation (ICARE) Stroke Initiative is a parallel group, three-arm, single blind, superiority randomized controlled trial of a theoretically-defensible, upper extremity rehabilitation program provided in the outpatient setting.The primary objective of ICARE is to determine if there is a greater improvement in arm and hand recovery one year after randomization in participants receiving a structured training program termed Accelerated Skill Acquisition Program (ASAP), compared to participants receiving usual and customary therapy of an equivalent dose (DEUCC). Two secondary objectives are to compare ASAP to a true (active monitoring only) usual and customary (UCC) therapy group and to compare DEUCC and UCC. METHODS/DESIGN Following baseline assessment, participants are randomized by site, stratified for stroke duration and motor severity. 360 adults will be randomized, 14 to 106 days following ischemic or hemorrhagic stroke onset, with mild to moderate upper extremity impairment, recruited at sites in Atlanta, Los Angeles and Washington, D.C. The Wolf Motor Function Test (WMFT) time score is the primary outcome at 1 year post-randomization. The Stroke Impact Scale (SIS) hand domain is a secondary outcome measure.The design includes concealed allocation during recruitment, screening and baseline, blinded outcome assessment and intention to treat analyses. Our primary hypothesis is that the improvement in log-transformed WMFT time will be greater for the ASAP than the DEUCC group. This pre-planned hypothesis will be tested at a significance level of 0.05. DISCUSSION ICARE will test whether ASAP is superior to the same number of hours of usual therapy. Pre-specified secondary analyses will test whether 30 hours of usual therapy is superior to current usual and customary therapy not controlled for dose.

Assessment of upper extremity impairment, function, and activity after stroke: foundations for clinical decision making. J Hand Ther 2013; 26:104-14;quiz 115.

Abstract
The purpose of this review is to provide a comprehensive approach for assessing the upper extremity (UE) after stroke. First, common UE impairments and how to assess them are briefly discussed. Although multiple UE impairments are typically present after stroke, the severity of one's impairment, paresis, is the primary determinant of UE functional loss. Second, UE function is operationally defined and a number of clinical measures are discussed. It is important to consider how impairment and loss of function affect UE activity outside of the clinical environment. Thus, this review also identifies accelerometry as an objective method for assessing UE activity in daily life. Finally, the role that each of these levels of assessment should play in clinical decision making is discussed to optimize the provision of stroke rehabilitation services.

Abstract
PURPOSE The purpose was to compare the effectiveness of robotic-assisted body weight supported treadmill training using the Lokomat(®) to over-ground gait training (OGT) in adults with chronic stroke. METHODS Participants were randomly assigned to the Lokomat(®) or OGT interventions. Both protocols included 40 sessions over 8 weeks. Primary outcome measures were the 10-meter walk test and 6-minute walk distance. Secondary measures included the Functional Independence Measure(TM) locomotion score, Fugl-Meyer Lower Extremity Motor Score (FM-LE), Barthel Index, and Stroke Impact Scale. Blinded assessors tested the participants at baseline, post-intervention, and 3-month follow-up. RESULTS Eleven Lokomat(®) and nine OGT participants completed the study. Within group differences in the FM-LE score and Barthel Index occurred over time from baseline to post-intervention and baseline to 3-month follow-up. No other within group differences and no between group differences were observed. CONCLUSIONS Although walking measures did not show significant changes between groups, LE motor function and physical functional levels improved over time within both groups. The Lokomat(®) may allow aggressive locomotor training, particularly for the lower functioning patients who wish to improve walking ability due to apparent eased therapist physical burden, when compared to OGT, although an increased risk of skin breakdown is present.

Abstract
BACKGROUND Involving patients in the determination of their care is increasingly important, and health-care professionals worldwide have recognized a need for clinical outcome measures and interventions that facilitate patient-centred care delivery in a range of settings. AIM A mixed-methods review was conducted, which aimed to identify stroke-specific patient-centred outcome measures and patient-centred interventions. SEARCH STRATEGY Databases searched included MEDLINE and PsycINFO; search strings were based on MeSH terms and keywords associated with the terms 'stroke' and 'patient-centred'. DATA EXTRACTION AND ANALYSIS Descriptive statistics were used to report quantitative data; thematic analysis was also performed in the included studies. MAIN RESULTS Three patient-centred outcome measures (Subjective Index of Physical and Social Outcomes, Stroke Impact Scale, Communication Outcome after Stroke scale) and four interventions were identified. Key elements of intervention design included delivery in people's own homes, involvement of families and tailoring to individual needs and priorities. Thematic analysis enabled description of three broad themes: meaningfulness and relevance, quality, and communication, which informed the development of a definition of patient-centred care specific to the specialty of stroke. CONCLUSIONS It is important for health-care professionals to ensure that their practice is relevant to patients and families. The review identified three stroke-specific patient-centred outcome measures, key elements of patient-centred interventions, and informed the development of a definition of patient-centred care. These review-derived outputs represent a useful starting point for health-care professionals, whatever their specialty, who are working to reconcile tensions between priorities of health-care professionals and those of patients and their families, to ensure delivery of patient-centred care.

Abstract
Theories of motor learning predict that training a movement reduces the amount of attention needed for its performance (i.e., more automatic). If training one movement transfers, then the amount of attention needed for performing a second movement should also be reduced, as measured under dual task conditions. The authors' purpose was to test whether dual task paradigms are feasible for detecting transfer of training between two naturalistic movements. Immediately following motor training, subjects improved performance of a second untrained movement under single and dual task conditions. Subjects with no training did not. Improved performance in the untrained movement was likely due to transfer, and suggests that dual tasks may be feasible for detecting transfer between naturalistic actions.

Abstract
OBJECTIVE. We determined (1) whether active range of motion (AROM) of shoulder flexion and wrist extension measured at the initial therapy evaluation in the acute hospital predicted upper-extremity (UE) motor function 3 mo after stroke and (2) whether the presence of nonmotor impairments influenced this prediction. METHOD. We collected AROM data from 50 people with stroke during their initial acute hospital therapy evaluation and UE motor function data 3 mo later. Multiple regression techniques determined the predictive ability of initial AROM on later UE motor function. RESULTS. Initial AROM explained 28% of the variance in UE motor function 3 mo poststroke. Nonmotor deficits did not contribute to the variance. CONCLUSION. Compared with later AROM measurements, initial values did not adequately predict UE motor function 3 mo after stroke. Clinicians should use caution when informing clients of UE functional prognosis in the early days after stroke.

Abstract
Objective To evaluate the spasticity and electrophysiologic effects of applying extracorporeal shock wave therapy (ESWT) to the gastrocnemius by studying F wave and H-reflex. Method Ten healthy adults and 10 hemiplegic stroke patients with ankle plantarflexor spasticity received one session of ESWT on the medial head of the gastrocnemius. The modified Ashworth scale (MAS), tibial nerve conduction, F wave, and H-reflex results were measured before and immediately after the treatment. The Visual Analogue Scale (VAS) was used during ESWT to measure the side effects, such as pain. Results There were no significant effects of ESWT on the conduction velocity, distal latency and amplitude of tibial nerve conduction, minimal latency of tibial nerve F wave, latency, or H-M ratio of H-reflex in either the healthy or stroke group. However, the MAS of plantarflexor was significantly reduced from 2.67±1.15 to 1.22±1.03 (p<0.05) after applying ESWT in the stroke group. Conclusion After applying ESWT on the gastrocnemius in stroke patients, the spasticity of the ankle plantarflexor was significantly improved, with no changes of F wave or H-reflex parameters. Further studies are needed to evaluate the mechanisms of the antispastic effect of ESWT.

Abstract
BACKGROUND AND PURPOSE This randomized controlled trial tests the efficacy of bilateral arm training with rhythmic auditory cueing (BATRAC) versus dose-matched therapeutic exercises (DMTEs) on upper-extremity (UE) function in stroke survivors and uses functional magnetic resonance imaging (fMRI) to examine effects on cortical reorganization. METHODS A total of 111 adults with chronic UE paresis were randomized to 6 weeks (3×/week) of BATRAC or DMTE. Primary end points of UE assessments of Fugl-Meyer UE Test (FM) and modified Wolf Motor Function Test Time (WT) were performed 6 weeks prior to and at baseline, after training, and 4 months later. Pretraining and posttraining, fMRI for UE movement was evaluated in 17 BATRAC and 21 DMTE participants. RESULTS The improvements in UE function (BATRAC: FM Δ = 1.1 + 0.5, P = .03; WT Δ = -2.6 + 0.8, P < .00; DMTE: FM Δ = 1.9 + 0.4, P < .00; WT Δ = -1.6 + 0.7; P = .04) were comparable between groups and retained after 4 months. Satisfaction was higher after BATRAC than DMTE (P = .003). BATRAC led to significantly higher increase in activation in ipsilesional precentral, anterior cingulate and postcentral gyri, and supplementary motor area and contralesional superior frontal gyrus (P < .05). Activation change in the latter was correlated with improvement in the WMFT (P = .01). CONCLUSIONS BATRAC is not superior to DMTE, but both rehabilitation programs durably improve motor function for individuals with chronic UE hemiparesis and with varied deficit severity. Adaptations in brain activation are greater after BATRAC than DMTE, suggesting that given similar benefits to motor function, these therapies operate through different mechanisms.

Abstract
This case report describes occupational therapy interventions focussed on improving the activities of daily living performance of a 73-year-old male recovering from Wallenberg syndrome, which resulted from a lateral medullary infarction. Historically, one of the most widely used approaches to physical rehabilitation in neurological populations has been the reflex-hierarchical theories, which are not supported in the literature as being effective for improving functional performance. Therefore, a contemporary task-oriented approach was used as a theoretical base for this case report. The Occupational Therapy Practice Framework was used to structure the occupational therapy evaluation, intervention, and outcome of this case.

Abstract
BACKGROUND Knowing how clinical tests are related to each other and whether tests are responsive to change are critical to evidence-based practice and sound research. OBJECTIVE To determine (1) relationships between six clinical tests of upper extremity function and (2) responsiveness for each test during the first six months after stroke. METHODS Grip strength test, pinch strength test, Action Research Arm Test, Jebsen-Taylor Hand Function Test, Nine-Hole Peg Test, and the Stroke Impact Scale-Hand domain were administered to 33 subjects within one, three, and six months after stroke. Spearman correlations were used to analyze relationships between tests. Responsiveness was calculated using the single population effect size method. RESULTS All tests were correlated with each other with absolute r-values ranging from 0.54 to 0.92 at one month, 0.57 to 0.97 at three months, and 0.41 to 0.97 at six months. All tests were at least moderately responsive to change, with effect sizes ranging from 0.50 to 1.02 from one to three months, and 0.56 to 0.86 (d) from one to six months. CONCLUSIONS Our data can assist clinicians and researchers in making decisions to use specific tests for measuring upper extremity function in people with hemiparesis in the first six months of recovery.

Abstract
This study investigated how the ability to extend the fingers and thumb recovers early after stroke and how the ability to extend all of the digits affects grasping performance. We studied 24 hemiparetic patients at 3 and 13 wk post stroke. At each visit, we tested the subjects' ability to actively extend all five digits of their contralesional, affected hand against gravity and to perform a grasp movement with the same hand. Three-dimensional motion analysis captured: 1) maximal voluntary extension excursion of each digit and 2) grasp performance variables of movement time, peak aperture, peak aperture rate, and aperture path ratio. We found that finger and thumb extension improved from 3 to 13 wk, with average improvements ranging from 12 to 19 degrees across the five digits. Grasp performance improved on two of the four variables measured. Peak apertures and peak aperture rates improved from 3 to 13 wk, but self-selected movement time and aperture path ratio did not. Stepwise multiple regression models showed that the majority of variance in grasp performance at 13 wk could be predicted by the ability to extend the index or middle finger at 3 wk, plus the change in the ability to extend the index finger from 3 to 13 wk. R2 values ranged from 0.55 to 0.89. Our data indicate that the amount of recovery in finger and thumb extension and grasping is small from 3 to 13 wk post stroke. In people with relatively pure motor hemiparesis, one important factor underlying deficits in hand shaping during grasping is the inability to extend the fingers and thumb. Without sufficient volitional control of finger and thumb extension, successful grasping of objects will not occur.

Abstract
BACKGROUND AND PURPOSE After stroke, 80% of patients experience acute paresis of the upper extremity and only approximately one-third achieve full functional recovery. Predicting functional recovery for these patients is highly important to provide focused, cost-effective rehabilitation. Our purpose was to examine if early measures of upper extremity active range of motion (AROM) could predict recovery of upper extremity function, and to describe the trajectory of upper extremity AROM recovery over time. METHODS Thirty-three subjects were tested at 1 month and then at 3 months after stroke. Upper extremity function was measured with 6 standardized clinical tests that were synthesized into a single, sensitive score for upper extremity function using principal component analysis. The ability to move each segment (AROM) was measured using a 3-dimensional electromagnetic tracking system. RESULTS Stepwise multiple regression revealed that AROM of the shoulder and middle finger segments taken at 1 month could predict 71% of the variance in upper extremity function at 3 months. All segments of the upper extremity recover similarly and no evidence of a proximal to distal gradient in motor deficits appeared over time. CONCLUSIONS Simple AROM measurements of the upper extremity taken within 1 month after stroke can be used to predict upper extremity function at 3 months. This information is important for determining the prognosis of upper extremity functional recovery.

Abstract
OBJECTIVE Our first purpose was to determine whether there was a proximal to distal gradient in motor deficits in nine segments of the affected upper extremity (shoulder, elbow, forearm, wrist, and five fingers) post-stroke. Our second purpose was to determine which upper extremity segments made the greatest contributions to hand function. METHODS Thirty-three subjects were tested on average 18.6 (+/-5.6) days after stroke. The ability to move each segment was measured by active range of motion (AROM). Hand function was measured by a battery of standardized clinical tests which were synthesized into a single, sensitive score for hand function using principal component analysis. RESULTS AROM at all nine segments of the upper extremity was reduced and there was no evidence of a proximal to distal gradient in AROM values. Strength of each segment was reduced and there was also no evidence of a gradient in strength values. AROM at each segment was strongly correlated with hand function scores (range 0.76-0.94). General multiple regression analysis showed that AROM explained 82% of the variance in hand function, with most of the variance shared across proximal, middle, and distal segments. Hierarchical regression analysis showed that shoulder AROM alone could explain 88% of the variance in hand function. CONCLUSIONS Early after stroke a proximal to distal gradient of motor deficits was not present, and loss of hand function was due to a loss of ability to move many segments of the upper extremity and not just the distal ones. SIGNIFICANCE These results suggest that a change in the clinical perception of motor deficits post-stroke is needed. Our finding that shoulder AROM predicted almost all the variance in hand function opens up the possibility that this quick, simple measure may be predictive of future hand function. This would be of high economic and clinical utility compared to other ongoing efforts attempting to predict outcomes post-stroke (e.g. fMRI, MEG).

Abstract
Background Despite intensive investigation, the origins of the neuromuscular abnormalities associated with spasticity are not well understood. In particular, the mechanical properties induced by stretch reflex activity have been especially difficult to study because of a lack of accurate tools separating reflex torque from torque generated by musculo-tendinous structures. The present study addresses this deficit by characterizing the contribution of neural and muscular components to the abnormally high stiffness of the spastic joint. Methods Using system identification techniques, we characterized the neuromuscular abnormalities associated with spasticity of ankle muscles in chronic hemiparetic stroke survivors. In particular, we systematically tracked changes in muscle mechanical properties and in stretch reflex activity during changes in ankle joint angle. Modulation of mechanical properties was assessed by applying perturbations at different initial angles, over the entire range of motion (ROM). Experiments were performed on both paretic and non-paretic sides of stroke survivors, and in healthy controls. Results Both reflex and intrinsic muscle stiffnesses were significantly greater in the spastic/paretic ankle than on the non-paretic side, and these changes were strongly position dependent. The major reflex contributions were observed over the central portion of the angular range, while the intrinsic contributions were most pronounced with the ankle in the dorsiflexed position. Conclusion In spastic ankle muscles, the abnormalities in intrinsic and reflex components of joint torque varied systematically with changing position over the full angular range of motion, indicating that clinical perceptions of increased tone may have quite different origins depending upon the angle where the tests are initiated. Furthermore, reflex stiffness was considerably larger in the non-paretic limb of stroke patients than in healthy control subjects, suggesting that the non-paretic limb may not be a suitable control for studying neuromuscular properties of the ankle joint. Our findings will help elucidate the origins of the neuromuscular abnormalities associated with stroke-induced spasticity.

Abstract
Our objective was to assess the mechanical changes associated with spasticity in elbow muscles of chronic hemiparetic stroke survivors and to compare these changes with those recorded in the ankle muscles of a similar cohort. We first characterized elbow dynamic stiffness by applying pseudorandom binary positional perturbations to the joints at different initial angles, over the entire range of motion, with subjects relaxed. We separated this stiffness into intrinsic and reflex components using a novel parallel cascade system identification technique. In addition, for controls, we studied the nonparetic limbs of stroke survivors and limbs of age-matched healthy subjects as primary and secondary controls. We found that both reflex and intrinsic stiffnesses were significantly larger in the stroke than in the nonparetic elbow muscles, and the differences increased as the elbow was extended. Reflex stiffness increased monotonically with the elbow angle in both paretic and nonparetic sides. In contrast, the modulation of intrinsic stiffness with elbow position was different in nonparetic limbs; intrinsic stiffness decreased sharply from full- to mid-flexion in both sides, then it increased continuously with the elbow extension in the paretic side. It remained invariant in the nonparetic side. Surprisingly, reflex stiffness was larger in the nonparetic than in the normal control arm, yet intrinsic stiffness was smaller in the nonparetic arm. Finally, we compare the angular dependence of paretic elbow and ankle muscles and show that the modulation of reflex stiffness with position was strikingly different.

Abstract
BACKGROUND Accounting for the influence of concurrent conditions on health and functional status for both research and clinical decision-making purposes is especially important in older adults. Although approaches to classifying severity of individual diseases and conditions have been developed, the utility of these classification systems has not been evaluated in the presence of multiple conditions. METHODS We present a framework for evaluating severity classification systems for common chronic diseases. The framework evaluates the: (a) goal or purpose of the classification system; (b) physiological and/or functional criteria for severity graduation; and (c) potential reliability and validity of the system balanced against burden and costs associated with classification. RESULTS Approaches to severity classification of individual diseases were not originally conceived for the study of comorbidity. Therefore, they vary greatly in terms of objectives, physiological systems covered, level of severity characterization, reliability and validity, and costs and burdens. Using different severity classification systems to account for differing levels of disease severity in a patient with multiple diseases, or, assessing global disease burden may be challenging. CONCLUSIONS Most approaches to severity classification are not adequate to address comorbidity. Nevertheless, thoughtful use of some existing approaches and refinement of others may advance the study of comorbidity and diagnostic and therapeutic approaches to patients with multimorbidity.

Abstract
Background and Objective . Loss of hand function in people with hemiparesis is a major contributor to disability poststroke. To use the hand for functional activities, a person may need control of the more proximal upper extremity segments to position and orient the hand with respect to the environment and may need control of the fingers to manipulate objects within the environment. The purpose of this project was to investigate how movement control at proximal, middle, and distal upper extremity segments contributed to loss of hand function in people with chronic hemiparesis. Methods. 32 patients with hemiparesis (avg 21.4 months postlesion) were studied making isolated movements of shoulder flexion, elbow flexion, forearm pronation/supination, wrist flexion/extension, and individual finger flexion using 3D kinematic techniques. For each segment, 3 variables were obtained: how far a segment could move (active range of motion [AROM]), how well a segment could move by itself (individuation index), and how well a segment could remain still when it was not supposed to move (stationary index). Hand function was measured with a battery of clinical tests, and principal components analysis was used to create a single hand function score for each patient from the test battery. Correlation and regression analyses were used to examine relationships between segmental movement control and hand function. Results. Movement control at all 9 segments of the upper extremity was related to hand function. Of the 9 segments, the thumb tended to have the weakest relationship with hand function. Of the 3 measures of movement control, AROM had strong relationships with and predicted the most variance in hand function (73%). Most of this variance was shared across segments, such that, for AROM, there were no unique contributions provided by proximal, middle, or distal segments. Conclusions. These data support the idea that loss of movement control covaries across segments and that loss of hand function is due to loss of movement control at all segments, not just at distal ones.

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.
