Patients' outcome expectations and their fulfilment in multidisciplinary stroke rehabilitation

Patient-Reported Variables Affecting Self-Perceived Overall Recovery Among People With Subacute Stroke

IMPORTANCE

Patients' perception of overall recovery is a critical outcome for stroke rehabilitation. However, the perception of overall recovery cannot be obtained using multidimensional measures, because satisfaction in most domains of life does not guarantee satisfaction in overall recovery. A single overall recovery score seems a straightforward measure. However, the clinical implications of overall scores are restricted, because factors affecting patients' overall recovery are unclear, which can be prioritized to optimize the effectiveness of rehabilitation.

OBJECTIVE

To examine patient-reported variables affecting overall recovery scores in patients with differing stroke severity.

DESIGN

The 59 items of the Stroke Impact Scale 3.0 were selected using regression analysis with a forward selection to explain the overall recovery score (0% = no recovery; 100% = full recovery). Stroke severity was determined with the National Institutes of Health Stroke Scale.

SETTING

Hospitals.

PARTICIPANTS

Data of 950 patients collected 90 days after stroke.

RESULTS

The models explained about 55% of the variance of the overall recovery scores with five to nine variables, but merely 16% of the variance was explained for patients with moderate stroke. As stroke severity increased, the number of identified variables decreased. Most identified variables were related to social participation and self-care activities (e.g., ability to help others, control the bowels, and dress the torso). Differences in the remaining variables depended on stroke severity.

CONCLUSIONS AND RELEVANCE

Patients' priorities differ depending on stroke severity. The identified variables may be set as treatment goals to optimize patients' self-perceived overall recovery. Plain-Language Summary: How patients perceive their overall recovery after a stroke is a critical outcome for their stroke rehabilitation. This study demonstrated that patients with different stroke severity may have different priorities that influence their self-perceived levels of overall recovery. The variables identified in this study may help occupational therapy practitioners identify meaningful goals to optimize patients' self-perceived overall recovery.

High-intensity interval training is feasible, credible and clinically effective in the early subacute stroke stage in the low-income country of Benin

High-intensity interval training (HIIT) has been shown to benefit stroke patients when implemented three months post-stroke. This study examined HIIT's feasibility and clinical effectiveness in the early post-stroke stage in Benin. This was a prospective interventional study comprising an HIIT programme executed on a recumbent bike, three times/week, 20-30 min/session for 6 weeks, added to a conventional physiotherapy. The primary outcomes were feasibility, credibility and expectancy assessed with credibility and expectancy questionnaire. A maximal exercise test, 6-min walking test (6MWT), 10-m walking test (10mWT), Berg balance scale (BBS) and five repetitions sit-to-stand test (5 R-STS) were performed before and after the training programme. Ten outpatients, with a median age [P25-P75]: 63.5[56.7-71.2] years; time since stroke: 15.0[9.7-21.0] days, started and completed all training sessions without serious adverse events. High scores were observed on the Credibility subscale at admission (27.0[25.7-27.0]), which remained so after intervention (26.5[25.7-27.0]). Expectancy subscale scores were high at admission (25.5[24.0-27.0]) and post-training (25.5[24.5-27.0]). Peak workload (p < 0.001), BBS (p < 0.001), 6MWT (p < 0.001), 10mWT (p < 0.001) and 5 R-STS (p = 0.004) were all improved. HIIT is feasible and safe in the early subacute post-stroke stage and is perceived by patients as highly credible, meeting their expectations of recovery.

Integrated Care in Neurology: The Current Landscape and Future Directions

The rising burden of neurological disorders poses significant challenges to healthcare systems worldwide. There has been an increasing momentum to apply integrated approaches to the management of several chronic illnesses in order to address systemic healthcare challenges and improve the quality of care for patients. The aim of this paper is to provide a narrative review of the current landscape of integrated care in neurology. We identified a growing body of research from countries around the world applying a variety of integrated care models to the treatment of common neurological conditions. Based on our findings, we discuss opportunities for further study in this area. Finally, we discuss the future of integrated care in Canada, including unique geographic, historical, and economic considerations, and the role that integrated care may play in addressing challenges we face in our current healthcare system.

Predicting the functional outcome of intensive inpatient rehabilitation after stroke: results from the RIPS Study

BACKGROUND

The complexity of stroke sequelae, the heterogeneity of outcome measures and rehabilitation pathways, and the lack of extensively validated prediction models represent a challenge in predicting stroke rehabilitation outcomes.

AIM

To prospectively investigate a multidimensional set of variables collected at admission to inpatient post-stroke rehabilitation as potential predictors of the functional level at discharge.

DESIGN

Multicentric prospective observational study.

SETTING

Patients were enrolled in four Intensive Rehabilitation Units (IRUs).

POPULATION

Patients were consecutively recruited in the period December 2019-December 2020 with the following inclusion criteria: aged 18+, with ischemic/haemorrhagic stroke, and undergoing inpatient rehabilitation within 30 days from stroke.

METHODS

This is a multicentric prospective observational study. The rehabilitation pathway was reproducible and evidence-based. The functional outcome was disability in activities of daily living, measured by the modified Barthel Index (mBI) at discharge. Potential multidimensional predictors, assessed at admission, included demographics, event description, clinical assessment, functional and cognitive profile, and psycho-social domains. The variables statistically associated with the outcome in the univariate analysis were fed into a multivariable model using multiple linear regression.

RESULTS

A total of 220 patients were included (median [IQR] age: 80 [15], 112 women, 175 ischemic). Median mBI was 26 (43) at admission and 62.5 (52) at discharge. In the multivariable analysis younger age, along with better functioning, fewer comorbidities, higher cognitive abilities, reduced stroke severity, and higher motor functions at admission, remained independently associated with higher discharge mBI. The final model allowed a reliable prediction of discharge functional outcome (adjusted R2=77.2%).

CONCLUSIONS

The model presented in this study, based on easily collectable, reliable admission variables, could help clinicians and researchers to predict the discharge scores of the global functional outcome for persons enrolled in an evidence-based inpatient stroke rehabilitation program.

CLINICAL REHABILITATION IMPACT

A reliable outcome prediction derived from standardized assessment measures and validated treatment protocols could guide clinicians in the management of patients in the subacute phase of stroke and help improve the planning of the rehabilitation individualized project.

Activity-Based Therapy for Mobility, Function and Quality of Life after Spinal Cord Injuries-A Mixed-Methods Case Series

(1) Background: Despite inconclusive evidence on the benefits of activity-based therapies (ABTs) in people with spinal cord injuries, implementation has occurred in clinics worldwide in response to consumers' requests. We explored the clinical changes and participants' perceptions from engaging in an ABT program in the community. (2) Methods: This mixed-methods study involved a pragmatic observational multiple-baseline design and an evaluation of participants' perceptions. Fifteen participants were included. Outcome measures were balance in sitting using the Seated Reach Distance test, mobility using the Modified Rivermead Mobility Index and quality of life using the Quality of Life Index SCI version pre- and post-participation in an ABT community-based program. Linear mixed models and logistic regressions were used to analyse the effects of intervention. Semi-structured interviews explored participants' perceptions using inductive thematic analysis. (3) Results: There was an increase of 9% in the standardised reach distance (95% CI 2-16) for sitting balance, 1.33 points (95% CI: 0.81-1.85) in mobility and 1.9 points (0.17-2.1) in quality of life. Two themes emerged from the interviews: (1) reduced impact of disability and an increased sense of life as before, and (2) the program was superior to usual rehabilitation. No adverse events related to the intervention were observed. (4) Conclusion: ABT delivered in the community improved clinical outcomes in people with a chronic SCI. High levels of satisfaction with the program were reported.

Acceptability, feasibility, and user satisfaction of a virtual reality relaxation intervention in a psychiatric outpatient setting during the COVID-19 pandemic

Background

The COVID-19 pandemic was particularly difficult for individuals with mental disorders. Due to governmental restrictions, face-to-face offers for psychiatric outpatients like therapies, psychoeducational groups or relaxation courses were limited. Virtual reality (VR) might be a new possibility to support these patients by providing them with a home-based relaxation tool.

Objective

The aim of this study was to evaluate the acceptability, feasibility, and user satisfaction of a supportive therapy-accompanying, relaxation VR intervention in psychiatric outpatients during the COVID-19 pandemic in Germany.

Methods

The four-weeks VR intervention consisted of regular watching of relaxing videos in the participants' home environment. Sociodemographics, feasibility (frequency of use, user-friendliness), satisfaction (Client Satisfaction Questionnaire-8), depressive symptoms (Patient Health Questionnaire-9), quality of life (abbreviated World Health Organization Quality of Life assessment), and credibility and expectancy (Credibility Expectancy Questionnaire-8) were measured in an intention-to-treat (ITT) analysis and a per-protocol (PP) analysis of completers.

Results

In total, N = 40 patients participated in the study. Most of the participants in the ITT analysis (n = 30, 75.0%) used the VR device three or 4 weeks. A majority of the N = 29 completers (PP: n = 18, 62.1%) used it all 4 weeks. Most participants used the device two or more times a week (ITT: n = 30, 83.3%; PP: n = 26, 89.7%) and described the user-friendliness as rather or very easy (ITT: n = 33, 91.7%; PP: n = 26, 89.7%). User satisfaction was high (ITT: 19.42, SD = 4.08; PP: M = 20.00, SD = 4.19) and did not correlate with participants' sex or age (all p < 0.05). Depressive symptoms and psychological quality of life improved significantly from pre-to post-intervention (ITT and PP, all p < 0.05). Higher pre-intervention credibility significantly correlated with a better outcome of satisfaction (ITT and PP), depressive symptoms, physical, psychological, and social quality of life (PP; all p < 0.05).

Conclusion

A supportive therapy-accompanying VR relaxation intervention is feasible and acceptable in a psychiatric outpatient setting. Due to the high satisfaction and user-friendliness, VR can be an easy to implement relaxation tool to support psychiatric outpatients.

Neurological Health: Not Merely the Absence of Disease: Current Wellbeing Instruments Across the Spectrum of Neurology

OBJECTIVE

Well-being and quality of life can vary independently of disease. Instruments measuring well-being and quality of life are commonly used in neurology, but there has been little investigation into the extent in which they accurately measure wellbeing/quality of life or if they merely reflect a diseased state of an individual.

DESIGN

Systematic searches, thematic analysis and narrative synthesis were undertaken. Individual items from instruments represented in ≥ 5 publications were categorised independently, without prior training, by five neurologists and one well-being researcher, as relating to 'disease-effect' or 'Well-being' with a study-created instrument. Items were additionally categorised into well-being domains.

DATA SOURCES

MEDLINE, EMBASE, EMCARE and PsycINFO from 1990 to 2020 were performed, across the 13 most prevalent neurological diseases.

RESULTS

301 unique instruments were identified. Multiple sclerosis had most unique instruments at 92. SF-36 was used most, in 66 studies. 22 instruments appeared in ≥ 5 publications: 19/22 'well-being' outcome instruments predominantly measured disease effect (Fleiss kappa = .60). Only 1/22 instruments was categorised unanimously as relating to well-being. Instruments predominantly measured mental, physical and activity domains, over social or spiritual.

CONCLUSIONS

Most neurological well-being or quality-of-life instruments predominantly measure disease effect, rather than disease-independent well-being. Instruments differed widely in well-being domains examined.

Contrasting expectancy effects with objective measures in adults with untreated ADHD during QbTest

Expectancy has been associated with neuropsychological assessments and cognitive performance. However, little is known about the effects of expectations in clinical assessments during drug trials with continuous performance tests (CPTs). In a randomized, double-blind study with cross-over design, we examined if the participants' self-reported expectations changed after one-single dose immediate release methylphenidate (MPH) and after one-single dose placebo during the QbTest. Forty adults between 19 and 64 years (72.5% women) with un treated ADHD were consecutively enrolled in the study and their assessments of expected performance, mental effort, perceived performance and help from the pill were analyzed. The study comprised two trial days with four days in between. The QbTest was performed twice on the same day, before and 80 minutes after a pill. Our study demonstrates that there were expectancy effects during CPTs. Participants reported lower mental effort and improved their performance in the coronary parameter QbInattention both after MPH and after placebo. No significant differences in expected performance were reported. The participants seemed to show some uncertainty when assessing their expected performance, however, they could evaluate their performance afterwards. In clinical practice, the focus should be on reinforcing patients' expectations in order to increase treatment effects.

Effect of acupuncture for disorders of consciousness in patients with stroke: A systematic review and meta-analysis

Background

Disorder of consciousness (DOC) is frequent in patients with stroke, which is the second most common cause of death and a leading cause of disability. Acupuncture has been used as a curative method for DOC treatment in China. Nevertheless, no critical systematic review of acupuncture's effect on DOC has been published. This review aims to evaluate the present evidence regarding the efficacy of acupuncture for DOC after stroke.

Methods

Seven databases were searched from their inception to November 1, 2021, containing three English databases (PubMed, Embase, and Cochrane Central Register of Controlled Trials) and four Chinese databases (CNKI, CBM, VIP, and Wanfang Database). The primary outcomes comprise the Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS) before and after treatment. Secondary outcomes involve resuscitation rate, resuscitation time, and adverse events. Data synthesis was calculated by RevMan (V.5.4.1) software. According to the Cochrane Handbook, methodological quality was assessed with the risk of bias tool 2.0 (RoB2).

Results

Seventeen studies containing 1,208 patients were eventually included in our review. Overall, most trials were rated as high or had some concerns regarding the risk of bias. GCS was reported in 16 trials, and a meta-analysis showed that GCS improvement in the acupuncture group was greater than in the non-acupuncture group (MD 1.45, 95% CI 0.94-1.97, P < 0.0001). One trial reported that GOS improvement in the acupuncture plus medication group was greater than in the medication group (MD 0.58, 95% CI 0.11-1.05, P = 0.01). Another study reported that acupuncture plus medication was statistically more effective in shortening resuscitation time than medication alone (MD-0.89, 95% CI -1.53 to -0.25, P = 0.006). Four trials reported that the resuscitation rate in the acupuncture group was higher than without acupuncture intervention (RR 1.68, 95% CI 1.30-2.18, I 2 0%, P = 0.39). Adverse events were reported in two studies, with one case in the acupuncture group suffering from subcutaneous hematoma.

Conclusion

Acupuncture may improve consciousness level, increase the resuscitation rate, and shorten resuscitation time for post-stroke patients with DOC. Adverse events from acupuncture were rare, tolerable, and recoverable. However, the results should be interpreted cautiously, and more rigorous RCTs with better methodology are warranted.

Health State Utility Values in People With Stroke: A Systematic Review and Meta-Analysis

Background Health state utility values are commonly used to provide summary measures of health-related quality of life in studies of stroke. Contemporaneous summaries are needed as a benchmark to contextualize future observational studies and inform the effectiveness of interventions aimed at improving post-stroke quality of life. Methods and Results We conducted a systematic search of the literature using Medline, EMBASE, and Web of Science from January 1995 until October 2020 using search terms for stroke, health-related quality of life, and indirect health utility metrics. We calculated pooled estimates of health utility values for EQ-5D-3L, EQ-5D-5L, AQoL, HUI2, HUI3, 15D, and SF-6D using random effects models. For the EQ-5D-3L we conducted stratified meta-analyses and meta-regression by key subgroups. We screened 14 251 abstracts and 111 studies met our inclusion criteria (sample size range 11 to 12 447). EQ-5D-3L was reported in 78% of studies (study n=87; patient n=56 976). The pooled estimate for EQ-5D-3L at ≥3 months following stroke was 0.65 (95% CI, 0.63-0.67), which was ≈20% below population norms. There was high heterogeneity (I2>90%) between studies, and estimates differed by study size, case definition of stroke, and country of study. Women, older individuals, those with hemorrhagic stroke, and patients prior to discharge had lower pooled EQ-5D-3L estimates. Conclusions Pooled estimates of health utility for stroke survivors were substantially below population averages. We provide reference values for health utility in stroke to support future clinical and economic studies and identify subgroups with lower healthy utility.

Baseline Predictors of Response to Repetitive Task Practice in Chronic Stroke

BACKGROUND

Repetitive task practice reduces mean upper extremity motor impairment in populations of patients with chronic stroke, but individual response is highly variable. A method to predict meaningful reduction in impairment in response to training based on biomarkers and other data collected prior to an intervention is needed to establish realistic rehabilitation goals and to effectively allocate resources.

OBJECTIVES

To identify prognostic factors and better understand the biological substrate for reductions in arm impairment in response to repetitive task practice among patients with chronic (≥6 months) post-stroke hemiparesis.

METHODS

The intervention is a form of repetitive task practice using a combination of robot-assisted therapy and functional arm use in real-world tasks. Baseline measures include the Fugl-Meyer Assessment, Wolf Motor Function Test, Action Research Arm Test, Stroke Impact Scale, questionnaires on pain and expectancy, MRI, transcranial magnetic stimulation, kinematics, accelerometry, and genomic testing.

RESULTS

Mean increase in FM-UE was 4.6 ± 1.0 SE, median 2.5. Approximately one-third of participants had a clinically meaningful response to the intervention, defined as an increase in FM ≥ 5. The selected logistic regression model had a receiver operating curve with AUC = .988 (Std Error = .011, 95% Wald confidence limits: .967-1) showed little evidence of overfitting. Six variables that predicted response represented impairment, functional, and genomic measures.

CONCLUSION

A simple weighted sum of 6 baseline factors can accurately predict clinically meaningful impairment reduction after outpatient intensive practice intervention in chronic stroke. Reduction of impairment may be a critical first step to functional improvement. Further validation and generalization of this model will increase its utility in clinical decision-making.

Acceptability and Feasibility of the Transfer of Face-to-Face Group Therapy to Online Group Chats in a Psychiatric Outpatient Setting During the COVID-19 Pandemic: Longitudinal Observational Study

BACKGROUND

At the height of the COVID-19 pandemic, several mental health care providers were obliged to shut down outpatient services, including group therapy and psychoeducational sessions. The lockdown in many countries is a serious threat to people's mental well-being, especially for individuals with severe mental illnesses. Discontinued outpatient treatments and disruption of daily routines are considered to be risk factors for destabilization of patients with mental illness.

OBJECTIVE

The aim of this study was to evaluate the acceptability, usability, and feasibility of a group chat program to replace cancelled face-to-face group sessions in an outpatient psychiatric department.

METHODS

Participants (N=33) were recruited in the outpatient department of a large university medical center in Leipzig, Germany. Former face-to-face group participants were invited to take part in a therapist-guided group-chat for 4 weeks (8 sessions) and were asked to evaluate the program via self-administered standardized questionnaires at baseline (T0, preintervention), after every chat session (T1), and posttreatment (T2, after 4-6 weeks). The chat groups were specific to the following mental disorder diagnoses and based on the same therapeutic principles and techniques as the former face-to-face groups: anxiety, depression, obsessive-compulsive disorder, and adult attention-deficit/hyperactivity disorder (ADHD). Sociodemographic measures, attitudes toward the COVID-19 pandemic, depressive symptoms (Patient Health Questionnaire-9), quality of life (abbreviated World Health Organization Quality of Life assessment), treatment credibility/expectancy (Credibility Expectancy Questionnaire), and participants' satisfaction (Client Satisfaction Questionnaire-8 [ZUF-8]) were measured.

RESULTS

Participants joined an average of 5 out of 8 offered chat sessions. Participation rates in the respective groups were highest in the ADHD group (8.6/11, 78%) and lowest in the anxiety group (3.7/9, 41%). The overall preintervention level of depressive symptoms was moderate and showed a slight, nonsignificant improvement at posttreatment (T0: mean 10.7, SD 5.5; T2: mean 10.2, SD 5.5). A similar result was observed regarding quality of life (T0: median 41.7-68.8; T2: median 50-70.3). Treatment credibility and expectancy scores were medium-high (T0: meancredibility 18.1, SD 3.8; meanexpectancy 11.2, SD 5.1; T2: meancredibility 17.1, SD 4.8; meanexpectancy 10.3, SD 5.8). Further, significant correlations were detected between posttreatment expectancy score and posttreatment PHQ-9 score (r=-0.41, P=.02), posttreatment physical quality of life (r=0.54, P=.001), and posttreatment psychological quality of life (r=0.53, P=.002). Overall, participants' satisfaction with the program was very high, both after chat sessions and at posttreatment (ZUF-8: mean score 20.6, SD 1.0). Of all participants, a majority (27/31, 87%) rated the program as excellent/good and indicated they would recommend the group chat program to a friend in need of similar help (23/31, 74%).

CONCLUSIONS

A therapist-guided group chat program to substitute outpatient group setting treatment during the COVID-19 lockdown was shown to be feasible, usable, and highly acceptable for participants. Web-based programs such as this one provide an easy-to-implement tool to successfully stabilize participants during a difficult time, such as the COVID-19 pandemic.

Post-stroke sleep disorders in Egyptian patients by using simply administered questionnaires: a study from Ain Shams University

Introduction

Stroke is a leading cause of disability worldwide with grave morbidity and mortality. Sleep and stroke have a definite intermingling neuropathological relationship, so along with expeditious acute management, efficient secondary prevention and consistent rehabilitation, sleep disorders’ management has a hand in offering a medical service up to the mark.

Objective

Screening of sleep disorders’ prevalence in patients who survived a previous stroke by applying simple questionnaires and to determine the correlation between these disorders and stroke’s demographic, clinical, and risk factor variables.

Methods

Cross-sectional prospective study on 75 stroke patients from stroke outpatient clinic and all patients were subjected to answer a sheet of sleep questionnaire, Pittsburg Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Apnea/Hypopnea Index (AHI), Arabic versions. Results

A total of 70.6 % were found to have sleep disorders, 61.6% had poor sleep quality, 20% had a severe degree of excessive day time sleepiness (EDS). Sleep disorders were more prevalent in the moderate severity of stroke by NIHSS and in the first 1–4 weeks. There was no correlation between the occurrence of sleep disorders and the site of the lesion.

Conclusion

Sleep disorders are broadly prevalent after a stroke. Resulting damage impedes the functional outcome. Simple questionnaires are easy applicable methods for screening of such disorders in post-stroke patients. Guidelines needed regarding screening and management of sleep disorders after a stroke.

Stroke Patients' Status Post-Acute Phase of Illness. How Is It and How Ought It to Be: Ain Shams University Experience

BACKGROUND

Stroke is a leading cause of disability worldwide with a great impact on quality of life. Ain Shams University Hospital is a tertiary center for neurology and a pioneer in offering comprehensive stroke service in the region.

METHODS

A cross sectional study in which an 8 domains questionnaire was applied to all cerebrovascular stroke patients who were admitted to the stroke unit of the neurology department of Ain Shams University Hospital in the period from January 2016 till May 2017, with the aim to define pitfalls in post discharge.

RESULTS

From our study show that 20% of all patients discharged from acute stroke unit did not have further follow up with any stroke doctor. Moreover, 60% of patients were not seen by a physiotherapist after discharge, including almost half of patients with moderate or severe disability on discharge who are expected to have ongoing care needs. Patients who developed stroke complications were more likely to seek follow up. As expected, continuous follow up was associated with increased adherence to secondary preventive medications.

CONCLUSIONS

Patient needs should be assessed before patient discharge and patient and care givers should have clear written information on required follow up with stroke doctors, and arrangements made for receiving adequate rehabilitation post discharge.

Methods for an Investigation of Neurophysiological and Kinematic Predictors of Response to Upper Extremity Repetitive Task Practice in Chronic Stroke

Objective

To demonstrate the feasibility of algorithmic prediction using a model of baseline arm movement, genetic factors, demographic characteristics, and multimodal assessment of the structure and function of motor pathways. To identify prognostic factors and the biological substrate for reductions in arm impairment in response to repetitive task practice.

Design

This prospective single-group interventional study seeks to predict response to a repetitive task practice program using an intent-to-treat paradigm. Response is measured as a change of ≥5 points on the Upper Extremity Fugl-Meyer from baseline to final evaluation (at the end of training).

Setting

General community.

Participants

Anticipated enrollment of community-dwelling adults with chronic stroke (N = 96; onset≥6mo) and moderate to severe residual hemiparesis of the upper limb as defined by a score of 10-45 points on the Upper Extremity Fugl-Meyer.

Intervention

The intervention is a form of repetitive task practice using a combination of robot-assisted therapy coupled with functional arm use in real-world tasks administered over 12 weeks.

Main Outcome Measures

Upper Extremity Fugl-Meyer Assessment (primary outcome), Wolf Motor Function Test, Action Research Arm Test, Stroke Impact Scale, questionnaires on pain and expectancy, magnetic resonance imaging, transcranial magnetic stimulation, arm kinematics, accelerometry, and a saliva sample for genetic testing.

Results

Methods for this trial are outlined, and an illustration of interindividual variability is provided by example of 2 participants who present similarly at baseline but achieve markedly different outcomes.

Conclusion

This article presents the design, methodology, and rationale of an ongoing study to develop a predictive model of response to a standardized therapy for stroke survivors with chronic hemiparesis. Applying concepts from precision medicine to neurorehabilitation is practicable and needed to establish realistic rehabilitation goals and to effectively allocate resources.
