Perceptions of Patients With Stroke Regarding an Immersive Virtual Reality-Based Exercise System for Upper Limb Rehabilitation: Questionnaire and Interview Study

BACKGROUND

With substantial resources allocated to develop virtual reality (VR)-based rehabilitation exercise programs for poststroke motor rehabilitation, it is important to understand how patients with stroke perceive these technology-driven approaches, as their perceptions can determine acceptance and adherence.

OBJECTIVE

This study aimed to examine the perceptions of patients with stroke regarding an immersive VR-based exercise system developed to deliver shoulder, elbow, forearm, wrist, and reaching exercises.

METHODS

A questionnaire was used to assess the perceptions of 21 inpatients who had experienced stroke (mean time from stroke onset: 37.2, SD 25.9 days; Brunnstrom stage of stroke recovery for the arm: 3-5) regarding the perceived usefulness of, ease of use of, attitude toward, intrinsic motivation for, and intention to use the exercise system. The measurement items were rated on a 7-point Likert scale ranging from 1 (very strongly disagree) to 7 (very strongly agree), with higher values indicating more positive perceptions. Descriptive statistics were used to summarize the responses. Moreover, we conducted semistructured interviews that were audio recorded, transcribed, and subjected to content analysis to identify thematic patterns.

RESULTS

The questionnaire results revealed that the patients' perceptions of the exercise system were positive (mean ratings >6). The content analysis revealed 6 positive themes from 73 statements about the exercise system: ease of use, usefulness, enjoyment, motivation, accessibility, and game design. Conversely, 15 statements reflected negative perceptions, which were clustered into 3 themes: difficulty in handling VR devices, uncomfortable experiences when using VR devices, and monotony.

CONCLUSIONS

Integrating VR technology into poststroke functional exercises holds significant promise based on patient interests. However, patient preferences and adaptability must be considered to promote the technology's success. VR-guided exercises should be user-friendly, health-promoting, engaging, and well-designed. Furthermore, addressing challenges, such as bulkiness, motion sickness, discomfort, and exercise monotony, is crucial for the widespread adoption and diffusion of this technology.

Virtual reality in stroke recovery: a meta-review of systematic reviews

BACKGROUND

Virtual Reality (VR) is an emerging technology in post stroke recovery. However, its precise role in stroke rehabilitation is not well defined. The aim of this paper is to conduct an overview of systematic reviews on the role of VR in stroke rehabilitation.

METHODS

A meta-review with results from a search of 7 databases from inception till 5th December 2022 with subsequent quality appraisal was conducted. The primary outcome was to produce a narrative review on the efficacy of VR versus usual or other care in stroke recovery. Data was synthesized in a descriptive fashion and high-quality systematic reviews were emphasized. The AMSTAR-2 tool was used for quality assessment of the included studies.

RESULTS

Evidence from high-quality systematic reviews suggests that there is benefit from VR in upper limb, lower limb, gait, and balance recovery particularly when additive to conventional therapy. There is also limited evidence to suggest that VR has a positive effect in those with impaired cognition.

CONCLUSION

VR is safe and effective as an adjunct to conventional therapy for adults after stroke and should be used routinely for upper and lower limb motor recovery. Further high-quality studies that evaluate its efficacy and explore ways to increase its positive impact in areas such as cognition are required. There is also a scope for the development of stroke-specific virtual environments. (PROSPERO registration # CRD42022372926).

A home-based hand rehabilitation platform for hemiplegic patients after stroke: A feasibility study

Background

Patients with stroke often experience weakened upper limbs, making daily tasks difficult to perform. Although rehabilitation devices are available, patients often relapse post-discharge due to insufficient practice. We present a home-based hand telerehabilitation intervention using the iManus™ platform comprising a sensorized glove, a mobile app for the patients, and a therapist portal for monitoring patient progress.

Objectives

This research aimed to examine the feasibility, safety, and effectiveness of a home-based telerehabilitation intervention in improving hand function for individuals with mild stroke. A qualitative approach was also used to explore users' experiences, perceived benefits, and challenges associated with using the platform in a home setting.

Methods

In this single-case study, we delivered a hand telerehabilitation intervention to a chronic stroke patient with impaired hand function using the iManus™ platform. The intervention consisted of 40 home sessions over eight weeks. We assessed feasibility through user adherence and feedback obtained using a System Usability Scale (SUS) and a semi-structured interview with the participant and their informal caregiver. Safety was evaluated by monitoring pain levels using the Visual Analog Scale (VAS), and efficacy was determined by observing the changes in the fingers' range of motion using the iManus™ platform and clinical outcomes measures, namely the Fugl-Meyer Assessment (FMA) and Jebsen Taylor Hand Function Test (JTHFT).

Results

Our participant completed all the assigned sessions, with each averaging 20 min. Usability scored 77.5 out of 100 on the SUS. User feedback from the interviews revealed improved mobility and control over therapy as benefits, indicating room for improvement in the intervention's adaptability and functionality. During the intervention, the participant noted no pain increase, and the telerehabilitation platform recorded range of motion improvements for all finger and wrist joints, excluding wrist extension. The FMA scores were 43 at T0, 53 at T1, and 56 at T2, while the JTHFT scores were 223 at T0, 188 at T1, and 240 at T2.

Conclusions

This single case study demonstrated the preliminary feasibility, safety, and efficacy of a novel home-based hand intervention for stroke survivors. The participant showed improved hand functions, good adherence to the program, and reported satisfaction with the intervention. However, these results are based on a single-case study, and further large-scale studies are needed before any generalization is recommended.

Effectiveness of virtual reality-supported exercise therapy in improving upper extremity function and activities of daily living among patients after stroke: a systematic review of randomized control trials

BACKGROUND

This systematic review describes the effectiveness of virtual reality (VR)-supported exercise therapy on upper limb motor function and activities of daily living after stroke.

METHODS

Studies published through January 24, 2022, were identified using CINAHL, Cochrane Library, Embase, Medline, and Web of Science. Randomized control trials comparing VR treatment with conventional therapy (CT) for upper extremity rehabilitation after stroke were included. Methodological quality was assessed using the Cochrane risk-of-bias tool.

RESULTS

Of 9 included studies, 5 concluded that the VR group outperformed control participants, 1 indicated the superiority of VR-supported exercises alone over CT, and 3 found VR comparable to CT in promoting upper limb motor function. Five studies analyzed independence in daily living, with 4 reporting no significant difference between VR and CT groups. No strong evidence indicated long-term benefits of VR-assisted exercise. All included studies demonstrated low risk of bias concerning random sequence generation, allocation concealment, outcome assessment blinding, incomplete outcome data, and selective reporting bias. However, a high risk of bias was observed regarding participant blinding due to the nature of the intervention.

CONCLUSION

Most studies suggested that VR, used alongside CT, can improve motor function following stroke. However, the evidence was insufficient to conclude that VR outperforms conventional approaches.

Utilization of early supported discharge and outpatient rehabilitation services following inpatient stroke rehabilitation

BACKGROUND

Studies examining factors associated with patient referral to early supported discharge (ESD)/outpatient rehabilitation (OPR) programs and utilization of ESD/OPR services after discharge from inpatient stroke rehabilitation (IPR) are scarce. Accordingly, we examined utilization of ESD/OPR services following discharge from IPR and patient factors associated with service utilization.

METHODS

Stroke patients discharged from IPR facilities in Alberta between April 2014 and March 2016 were included and followed for one year for ESD/OPR service utilization. Multivariable linear and negative binomial regressions were used to examine association of patients' factors with ESD/OPR use.

RESULTS

We included 752 patients (34.4% of 2,187 patients discharged from IPR) who had 40,772 ESD/OPR visits during one year of follow-up in the analysis. Mean and median ESD/OPR visits were 54.2 and 36 visits, respectively. Unadjusted ESD/OPR visits were lower in females and patients aged ≥ 60 years but were similar between urban and rural areas. After adjustment for patient factors, patients in urban areas and discharged home after IPR were associated with 83.5% and 61.9%, respectively, increase in ESD/OPR visits, while having a right-body stroke was associated with 23.5% increase. Older patients used ESD/OPR less than their younger counterparts (1.4% decrease per one year of older age). Available factors explained 12.3% of variation in ESD/OPR use.

CONCLUSION

ESD/OPR utilization after IPR in Alberta was low and varied across age and geographic locations. Factors associated with use of ESD/OPR were identified but they could not fully explain variation of ESD/OPR use.

Study of the Possibility of Using Virtual Reality Application in Rehabilitation among Elderly Post-Stroke Patients

Thanks to medical advances, life expectancy is increasing. With it comes an increased incidence of diseases, of which age is a risk factor. Stroke is among these diseases, and is one of the causes of long-term disability. The opportunity to treat these patients is via rehabilitation. A promising new technology that can enhance rehabilitation is virtual reality (VR). However, this technology is not widely used by elderly patients, and, moreover, the elderly often do not use modern technology at all. It therefore becomes a legitimate question whether elderly people will be able to use virtual reality in rehabilitation. This article presents a rehabilitation application dedicated to patients with upper limb paresis and unilateral spatial neglect (USN). The application was tested on a group of 60 individuals including 30 post-stroke patients with an average age of 72.83 years. The results of the conducted study include a self-assessment by the patients, the physiotherapist's evaluation, as well as the patients' performance of the exercise in VR. The study showed that elderly post-stroke patients are able to use virtual reality applications, but the ability to correctly and fully perform an exercise in VR depends on several factors. One of them is the ability to make logical contact (p = 0.0001 < 0.05). However, the study presented here shows that the ability to use VR applications does not depend on age but on mental and physical condition, which gives hope that virtual reality applications can be used in post-stroke rehabilitation among patients of all ages.

Botulinum toxin A injection for post-stroke upper limb spasticity and rehabilitation practices from centers across Asian countries

Purpose

Describe real-life practice and outcomes in the management of post-stroke upper limb spasticity with botulinum toxin A (BoNT-A) in Asian settings.

Methods

Subgroup analysis of a prospective, observational study (NCT01020500) of adult patients (≥18 years) with post-stroke upper limb spasticity presenting for routine spasticity management, including treatment with BoNT-A. The primary outcome was goal attainment as assessed using goal-attainment scaling (GAS). Patients baseline clinical characteristics and BoNT-A injection parameters are also described.

Results

Overall, 51 patients from Asia were enrolled. Rates of comorbid cognitive and emotional problems were relatively low. Patients tended to have more severe distal limb spasticity and to prioritize active over passive function goals. Most (94.1%) patients in the subgroup were treated with abobotulinumtoxinA. For these patients, the median total dose was 500 units, and the most frequently injected muscles were the biceps brachii (83.3%), flexor carpi radialis (72.9%), and flexor digitorum profundus (66.7%). Overall, 74.5% achieved their primary goal and the mean GAS T score after one treatment cycle was 56.0 ± 13.0, with a change from baseline of 20.9 ± 14.3 (p < 0.001). The majority (96.1%) of Asian patients were rated as having improved.

Conclusion

In the Asian treatment setting, BoNT-A demonstrated a clinically significant effect on goal attainment for the real-life management of upper limb spasticity following stroke.

Comparing the Effects of Virtual Reality Breathing Exercise and Incentive Spirometry Exercise on Improving Pulmonary Function in Children with Spastic Diplegic Cerebral Palsy

INTRODUCTION

Children with cerebral palsy (CP) have a higher incidence of respiratory dysfunction than healthy children. Virtual reality breathing therapy is an assistive technology that is becoming popular in the rehabilitation of children with CP.

METHODS

This experimental study included a total of 32 children with spastic diplegic CP who were divided into two groups: the virtual reality breathing training (VRBT) group and the incentive spirometry (IST) group. Individuals classified as levels I to III on the gross motor function classification system (GMFCS) were recruited using the simple random sampling method.

RESULT

The results of comparing the values of forced vital capacity (FVC), forced expiratory volume at one second (FEV1), and the ratio of FVC/FEV1 showed a significant difference between groups. A significant difference was found in the VRBT group compared to the IST group, except for the peak expiratory flow (PEF) values, which showed a nonsignificant difference between the groups.

CONCLUSION

There were significant differences in FVC and FEV1 between the VRBT and IST groups. It has been concluded that VRBT has additional benefits in improving pulmonary functions.

Immersive virtual reality-based rehabilitation for subacute stroke: a randomized controlled trial

OBJECTIVE

Few effective treatments improve upper extremity (UE) function after stroke. Immersive virtual reality (imVR) is a novel and promising strategy for stroke UE recovery. We assessed the extent to which imVR-based UE rehabilitation can augment conventional treatment and explored changes in brain functional connectivity (FC) that were related to the rehabilitation.

METHODS

An assessor-blinded, parallel-group randomized controlled trial was performed with 40 subjects randomly assigned to either imVR or Control group (1:1 allocation), each receiving rehabilitation 5 times per week for 3 weeks. Subjects in the imVR received both imVR and conventional rehabilitation, while those in the Control received conventional rehabilitation only. Our primary and secondary outcomes were the Fugl-Meyer assessment's upper extremity subscale (FMA-UE) and the Barthel Index (BI), respectively. Both intention-to-treat (ITT) and per-protocol (PP) analyses were performed to assess the effectiveness of the trial. For both the FMA-UE/BI, a one-way analysis of covariance (ANCOVA) model was used, with the FMA-UE/BI at post-intervention or at follow-up, respectively, as the dependent variable, the two groups as the independent variable, baseline FMA-UE/BI, age, sex, site, time since onset, hypertension and diabetes as covariates.

RESULTS

Both ITT and PP analyses demonstrated the effectiveness of imVR-based rehabilitation. The FMA-UE score was greater in the imVR compared with the Control at the post-intervention (mean difference: 9.1 (95% CI 1.6, 16.6); P = 0.019) and follow-up (mean difference:11.5 (95% CI 1.9, 21.0); P = 0.020). The results were consistent for BI scores. Moreover, brain FC analysis found that the motor function improvements were associated with a change in degree in ipsilesional premotor cortex and ipsilesional dorsolateral prefrontal cortex immediately following the intervention and in ipsilesional visual region and ipsilesional middle frontal gyrus after the 12-week follow-up.

CONCLUSIONS

ImVR-based rehabilitation is an effective tool that can improve the recovery of UE functional capabilities of subacute stroke patients when added to standard care. These improvements were associated with distinctive brain changes at two post-stroke timepoints. The study results will benefit future patients with stroke and provide evidence for a promising new method of stroke rehabilitation.

Exploring the efficacy of virtual reality-based rehabilitation in stroke: a narrative review of current evidence

BACKGROUND

Stroke rehabilitation presents a complex challenge, necessitating innovative approaches to optimise functional recovery. Virtual Reality-Based Rehabilitation (VRBR) has emerged as a promising intervention that capitalises on immersive technology to engage stroke survivors in their recovery journey. This review aims to examine the efficacy of VRBR in stroke rehabilitation, focusing on its advantages and challenges.

METHODS

A comprehensive search of relevant literature was conducted to gather evidence on the efficacy of VRBR in stroke survivors. Studies that investigated the impact of VRBR on patient engagement, functional recovery, and overall rehabilitation outcomes were included. The review also assessed the ability of VRBR to simulate real-life scenarios and facilitate essential daily activities for stroke survivors.

RESULTS

The review highlights that VRBR offers a unique immersive experience that enhances patient engagement and motivation during rehabilitation. The immersive nature of VRBR fosters a sense of presence, which can positively impact treatment adherence and outcomes. Moreover, VRBR's capacity to replicate real-world scenarios provides stroke survivors with opportunities to practice vital daily activities, promoting functional independence. In contrast, conventional rehabilitation methods lack the same level of engagement and real-world simulation.

CONCLUSION

VRBR holds promise as an efficacious intervention in stroke rehabilitation. Its immersive nature enhances patient engagement and motivation, potentially leading to better treatment adherence and outcomes. The ability of VRBR to simulate real-life scenarios offers a unique platform. However, challenges such as cost, equipment, patient suitability, data privacy, and acceptance must be addressed for successful integration into stroke rehabilitation practice.

Exploring community reintegration among Nigerian stroke survivors

Background

Community reintegration is one of the ultimate goals of stroke rehabilitation. The increasing burden of stroke morbidity by other non-communicable diseases in Nigeria indicated the need for our study.

Objectives

The authors explored the factors contributing to successful community reintegration among Nigerian stroke survivors.

Method

We conducted an explorative qualitative study design to achieve this aim using in-depth semi-structured interviews with 12-purposively sampled stroke survivors.

Results

Three overarching themes emerged: restriction of participation experienced by stroke survivors, activity limitation as pointers to the quality-of-life experience of stroke survivors and enablers or barriers to community reintegration for stroke survivors. Among the core, sub-themes included incapability of returning to work, difficulty performing domestic activities, social isolation or separation, recreation and leisure time. Enablers of community reintegration included creating a positive mindset, encouragement and social support, while barriers included mobility and speech or language challenges.

Conclusion

Stroke survivors have challenges in returning to work and experience varying levels of activity limitation, which affects their quality of life with identifiable enablers or barriers to community reintegration.

Clinical implications

Stroke survivors with severe functional deficits should be monitored closely and given further rehabilitative assistance to aid functional recovery, thereby facilitating community reintegration.

A qualitative evidence synthesis exploring people after stroke, family members, carers and healthcare professionals' experiences of early supported discharge (ESD) after stroke

OBJECTIVE

Early supported discharge (ESD) after stroke has been shown to generate significant cost savings and reduce both hospital length of stay, and long-term dependency. This study aimed to systematically review and synthesise qualitative studies of the experiences and views of ESD from the perspective of people after stroke, their family members, carers and healthcare professionals.

METHOD

A systematic search of eleven databases; CINAHL, PubMed Central, Embase, MEDLINE, PsycINFO, Sage, Academic Search Complete, Directory of Open Access Journal, The Cochrane Library, PsycARTICLES and SCOPUS, was conducted from 1995 to January 2022. Qualitative or mixed methods studies that included qualitative findings on the perspectives or experiences of people after stroke, family members, carers and healthcare professionals of an ESD service were included. The protocol was registered with the Prospero database (Registration: CRD42020135197). The methodological quality of studies was assessed using the 10-item CASP checklist for qualitative studies. Results were synthesised using Thomas and Harden's three step approach for thematic synthesis.

RESULTS

Fourteen studies were included and five key themes were identified (1) ESD eases the transition home, but not to community services, (2) the home environment enhances rehabilitation, (3) organisational, and interprofessional factors are critical to the success of ESD, (4) ESD is experienced as a goal-focused and collaborative process, and (5) unmet needs persisted despite ESD.

CONCLUSION

The findings of this qualitative evidence synthesis highlight that experiences of ESD were largely very positive. The transition from ESD to community services was deemed to be problematic and other unmet needs such as information needs, and carer support require further investigation.

Pervasive Healthcare Internet of Things: A Survey

Thanks to the proliferation of the Internet of Things (IoT), pervasive healthcare is gaining popularity day by day as it offers health support to patients irrespective of their location. In emergency medical situations, medical aid can be sent quickly. Though not yet standardized, this research direction, healthcare Internet of Things (H-IoT), attracts the attention of the research community, both academia and industry. In this article, we conduct a comprehensive survey of pervasive computing H-IoT. We would like to visit the wide range of applications. We provide a broad vision of key components, their roles, and connections in the big picture. We classify the vast amount of publications into different categories such as sensors, communication, artificial intelligence, infrastructure, and security. Intensively covering 118 research works, we survey (1) applications, (2) key components, their roles and connections, and (3) the challenges. Our survey also discusses the potential solutions to overcome the challenges in this research field.

An evaluation of the structure and process of stroke rehabilitation in primary, secondary and tertiary hospitals in Ghana

Background

Evidence shows that quality indicators such as the structure and process of stroke rehabilitation can influence patient outcomes. However, not much attention has been paid to the study of these issues in low- and middle-income countries such as Ghana.

Objectives

Our study evaluated the structure and process of stroke rehabilitation in primary, secondary and tertiary hospitals in the Greater Accra Region of Ghana.

Method

A cross-sectional survey was conducted involving 111 healthcare professionals. The World Health Organization (WHO) situational analysis and Measure of Processes of Care for Service Providers for Adults (MPOC-SP[A]) questionnaires were administered to gather information on the structure and process of stroke rehabilitation. Descriptive statistics were used to summarise data, and chi-square and Kruskal–Wallis tests were used to establish associations and comparisons, respectively.

Results

A stroke unit was only available in the tertiary hospital. Although all three hospitals had a multidisciplinary team approach to care, the constituents differed. Length of hospital-stay, duration of treatment and basis for discharge from acute care were not associated with the hospitals. Therapy sessions, access to computed tomography (CT) and magnetic resonance imaging (MRI) scanning were dependent on the hospitals.

Conclusion

The structure and process of stroke rehabilitation across the three hospitals were similar in some constructs and different in others.

Clinical implications

Data gathered will help to provide information on the available structure and processes of stroke rehabilitation, which could help assess the quality of care provided.

Investigating the dose-response relationship between motor imagery and motor recovery of upper-limb impairment and function in chronic stroke: A scoping review

The recovery of upper-limb impairment and dysfunction post-stroke is often incomplete owing to the limited time in therapy focused on upper-limb recovery and the severity of the impairment. In these cases, motor imagery (MI) may be used as a precursor to physical therapies to initiate rehabilitation early on when it would be otherwise impossible to engage in therapy, as well as to increase the dose of therapy when MI is used in adjunct to physical therapy. While previous reviews have shown MI to be effective as a therapeutic option, disparity in findings exists, with some studies suggesting MI is not an effective treatment for post-stroke impairment and dysfunction. One factor contributing to these findings is inconsistency in the dose of MI applied. To explore the relationship between MI dose and recovery, a scoping review of MI literature as a treatment for adult survivors of stroke with chronic upper-limb motor deficit was performed. Embase, Medline and CINHAL databases were searched for articles related to MI and stroke. Following a two-phase review process, 21 papers were included, and data related to treatment dose and measures of impairment and function were extracted. Effect sizes were calculated to investigate the effect of dosage on motor recovery. Findings showed a high degree of variability in dosage regimens across studies, with no clear pattern for the effect of dose on outcome. The present review highlights the gaps in MI literature, including variables that contribute to the dose-response relationship, that future studies should consider when implementing MI.

Evidence-based stroke rehabilitation: do priorities for practice change and feasibility of implementation vary across high income, upper and lower-middle income countries?

PURPOSE

The context of implementation plays an important role in the delivery of optimal treatments in stroke recovery and rehabilitation. Considering that stroke systems of care vary widely across the globe, the goal of the present paper is to compare healthcare providers' priority of key areas in translating stroke research to clinical practice among High Income Countries, Upper Middle- and Lower Middle-Income Countries (HICs, UMICs, LMICs). We also aimed to compare perceptions regarding the key areas' feasibility of implementation, and formulate recommendations specific to each socioeconomic region.

METHODS

Data related to recommendations for knowledge translation in stroke, from a primary survey from the second Stroke Recovery and Rehabilitation Roundtable were segregated based on socioeconomic region. Frequency distribution was used to compare the key areas for practice change and examine the perceived feasibility of implementation of the same across HIC, UMIC and LMICs.

RESULTS

A total of 632 responses from healthcare providers across 28 countries were received. Interdisciplinary care and access to services were high priorities across the three groups. Transitions in Care and Intensity of Practice were high priority areas in HICs, whereas Clinical Practice Guidelines were a high priority in LMICs. Interventions specific to clinical discipline, screening and assessment were among the most feasible areas in HICs, whereas Intensity of practice and Clinical Practice Guidelines were perceived as most feasible to implement in LMICs.

CONCLUSION

We have identified healthcare providers' priorities for addressing international practice change across socioeconomic regions. By focusing on the most feasible key areas, we can aid the channeling of appropriate resources to bridge the disparities in stroke outcomes across HICs, UMICs and LMICs.IMPLICATIONS FOR REHABILITATIONIt is pertinent to examine the differences in priorities of stroke rehabilitation professionals and the feasibility of implementing evidence-based practice across socioeconomic regions.There is an urgent necessity for the development of clinical practice guidelines for stroke rehabilitation in Low-Middle Income Countries, taking into consideration the cultural, economic and geographical constraints.In upper-middle income countries, encouraging family support and timely screening and assessment for aphasia, cognition and depression appear to be the low hanging fruits to enhance quality of life after stroke.Innovative ways to increase intensity of practice and channelling of resources to improve transitions in care may prove to be the most beneficial in advancing stroke rehabilitation in high income countries.

A protocol for a qualitative synthesis exploring people with stroke, family members, caregivers and healthcare professionals experiences of early supported discharge (ESD) after stroke

Early supported discharge (ESD) facilitates a person with a stroke to be discharged from the acute hospital environment earlier than conventional care to continue their rehabilitation within the home with members of the multi-disciplinary team. A number of quantitative studies have highlighted benefits of ESD including a reduction in the length of inpatient stay, cost savings, as well as reducing long term dependency. This systematic review and qualitative synthesis explores the perspectives and experiences of those involved in ESD including people with stroke, family members, caregivers as well as the healthcare professionals involved in the delivery of the service. A comprehensive literature search will be completed in the following databases CINAHL, PubMed Central, Embase, Medline, PsycINFO, Sage, Academic Search Complete, Directory of Open Access Journals, The Cochrane Library, PsycARTICLES and Scopus. Qualitative or mixed methods studies that include qualitative data on the perspectives and experiences of people with stroke, family members, caregivers and healthcare professionals of an ESD service will be included. Methodological quality will be appraised using the ten-item Critical Appraisal Skills Programme checklist for qualitative research by two independent reviewers with a third reviewer involved should differences of opinion arise. Findings will be synthesised using thematic synthesis.    It is anticipated that the qualitative synthesis will provide a deeper understanding of the experiences of ESD which may serve to inform practice as well as assist in the development of new ESD services.

Health Professional Perspectives on Rehabilitation for People With Dementia

BACKGROUND AND OBJECTIVES

Multidisciplinary rehabilitation is not incorporated into the usual care pathway for dementia despite increasing demand from key advocates. Clinician views regarding the relevance of rehabilitation in dementia care are not well known. This qualitative study explored the perspectives of health professionals regarding barriers to provision of multidisciplinary rehabilitation programs for people with dementia.

RESEARCH DESIGN AND METHODS

Sixteen health professionals from a variety of settings and professional backgrounds were purposively sampled using maximum variation sampling. Semi-structured interviews were conducted to explore attitudes toward the care of people with dementia and beliefs about the feasibility and value of multidisciplinary rehabilitation in this population. Thematic analysis was used to identify themes.

RESULTS

Participating clinicians acknowledged problems with existing dementia care pathways in Australia but rarely conceptualized rehabilitation as relevant to this pathway. Analyses yielded two main and related themes: (i) difficulty defining worthwhile outcomes of a rehabilitation program for people with dementia and (ii) perceived barriers to participation in this population. Clinicians felt that achievable outcomes for people with dementia were not sufficiently worthwhile for investment.

DISCUSSION AND IMPLICATIONS

Broader acceptance of multidisciplinary rehabilitation as relevant to dementia care will require a reframing of practice that both educates emerging health professionals regarding the outcomes that may be achievable for people with dementia and persuades staff to appreciate that the investment is worthwhile.

Development of a Diagnosis and Evaluation System for Hemiplegic Patients Post-Stroke Based on Motion Recognition Tracking and Analysis of Wrist Joint Kinematics

An inexperienced therapist lacks the analysis of a patient's movement. In addition, the patient does not receive objective feedback from the therapist due to the visual subjective judgment. The aim is to provide a guide for in-depth rehabilitation therapy in virtual space by continuously tracking the user's wrist joint during Leap Motion Controller (LMC) activities and present the basic data to confirm steady therapy results in real-time. The conventional Box and Block Test (BBT) is commonly used in upper extremity rehabilitation therapy. It was modeled in proportion to the actual size and Auto Desk Inventor was used to perform the 3D modeling work. The created 3D object was then implemented in C # through Unity5.6.2p4 based on LMC. After obtaining a wrist joint motion value, the motion was analyzed by 3D graph. Healthy subjects (23 males and 25 females, n = 48) were enrolled in this study. There was no statistically significant counting difference between conventional BBT and system BBT. This indicates the possibility of effective diagnosis and evaluation of hemiplegic patients post-stroke. We can keep track of wrist joints, check real-time continuous feedback in the implemented virtual space, and provide the basic data for an LMC-based quantitative rehabilitation therapy guide.

Combining Proprioceptive Neuromuscular Facilitation and Virtual Reality for Improving Sensorimotor Function in Stroke Survivors: A Randomized Clinical Trial

Aim:

To assess a program combining virtual reality (VR) games and proprioceptive neuromuscular facilitation (PNF) and to compare it with the standalone techniques in stroke survivors.

Methods:

A randomized controlled clinical trial. A total of 48 participants were recruited in the outpatient clinic of a University Hospital in Salvador, Brazil. They were randomly assigned to 3 groups (n = 16 each): PNF, VR, and PNF/VR. Participants attended twice-weekly 50-minute sessions over a 2-month period. The PNF/VR group performed both PNF and VR exercises employing Nintendo Wii electronic games. Motor performance was assessed before and immediately after the treatment using the Fugl-Meyer Assessment scale.

Results:

An improvement in the mean scores was observed after treatment independent of the allocation group with significant intragroup changes: 14.5, 10.5, and 10.4 for PNF, VR, and PNF/VR, respectively. Score changes were also observed in the analyses of specific sections as follows: (1) a significant improvement in the passive movement and pain score was observed in the PNF and PNF/VR groups; (2) the same was observed for the motor function of the upper limb in all groups, for the motor function of the lower limb in the VR group and for balance in the PNF and PNF/VR groups.

Conclusions:

The use of a program combining virtual rehabilitation and PNF presented results that were comparable with those obtained with the isolated techniques.

Wrist Rehabilitation System Using Augmented Reality for Hemiplegic Stroke Patient Rehabilitation: A Feasibility Study

Objective: Our objective was to investigate the effect of the rehabilitation system using augmented reality (AR) on upper extremity motor performance of patients with stroke. Methods: The system using AR applying mirror therapy mechanism provides the intervention protocol for the patient with hemiplegia after stroke. The system consists of a patient positioning tool (a chair), a white surface table, an image acquisition unit, an image processing unit, an image displaying unit, an arm holder, a Velcro-strap, and two blue circle stickers. To assess the feasibility of our system in motor function recovery, a stroke patient was recruited to receive the AR intervention. The treatment was performed two times a day for ten minutes over two weeks (ten days of treating weeks), except for the time of installation, calibration, and three minute breaks. Jebsen Taylor hand function test and Arm Motor Fugl-Meyer assessment were used as primary and secondary outcome measures, respectively, to evaluate the effect of motor function recovery. Additionally, stroke impact scale, Korean version-Modified Barthel Index (K-MBI), active range of motion of wrist joint (ROM), and the grasp force in Newtons were measured. Participants’ feedback and adverse effects were recorded as well. Results: Motor function improvements were exhibited in wrist and hand subtest of Arm Motor Fugl-Meyer (baseline: 19; post-intervention: 23), proximal arm subtest of Fugl-Meyer (baseline: 31; post-intervention: 34), ROM (extending ROM: 10° and 3° for flexion and extension, repeatedly), stroke impact scale (baseline: 46; post-intervention: 54), K-MBI (baseline: 92; post-intervention: 95), nine-hole pegboard (baseline: 30 s; post-intervention: 25 s), and grasp force in Newtons (baseline: 12.7; post-intervention: 17.7). However, the adverse effects were reported after the intervention. Conclusion: The system using AR applying mirror therapy mechanism demonstrated the feasibility in motor function recovery for the stroke patient.

Effect of a Soft Robotic Sock Device on Lower Extremity Rehabilitation Following Stroke: A Preliminary Clinical Study With Focus on Deep Vein Thrombosis Prevention

BACKGROUND AND OBJECTIVE

Immobility of the lower extremity due to medical conditions such as stroke can lead to medical complications such as deep vein thrombosis or ankle contracture, and thereafter prolonged recovery process of the patients. In this preliminary clinical study, we aimed to examine the effect of a novel soft robotic sock device, capable of providing assisted ankle exercise, in improving blood flow in the lower limb to prevent the complication of strokes such as deep vein thrombosis and joint contracture.

METHODS

Stroke patients were recruited (n = 17) to compare patients using the conventional pneumatic compression device with our robotic sock device on separate days. The primary outcome was to compare the venous flow profile of the superficial femoral vein in terms of the time average mean velocity and volumetric flow. The secondary outcome was to identify the ankle joint range of motion with the assistance of the device.

RESULTS

We noted improvements in the venous profile at the early phase of the device use, though its efficacy seemed to drop with time, as compared to the IPC device, where there was a significant improvement in the venous profile. The ankle joint dorsiflexion-plantarflexion range of motion assisted by the device was 11.5±6.3°. Conclusion and clinical impact: The current version of our sock device appears to be capable of improving venous blood flow in the early phase of device use and assisting with ankle joint exercise. The insights from this preliminary clinical study will serve as the basis for further improvement of the device and subsequent conduct of a longitudinal clinical trial.

Evaluating the effect and mechanism of upper limb motor function recovery induced by immersive virtual-reality-based rehabilitation for subacute stroke subjects: study protocol for a randomized controlled trial

BACKGROUND

There is compelling evidence of beneficial effects of non-immersive virtual reality (VR)-based intervention in the rehabilitation of patients with stroke, whereby patients experience both the real world and the virtual environment. However, to date, research on immersive VR-based rehabilitation is minimal. This study aims to design a randomized controlled trial to assess the effectiveness of immersive VR-based upper extremity rehabilitation in patients with subacute stroke and explore the underlying brain mechanisms of immersive VR-based rehabilitation.

METHODS

Subjects (n = 60) with subacute stroke (defined as more than 1 week and less than 12 weeks after stroke onset) will be recruited to participate in a single-blinded, randomized controlled trial. Subjects will be randomized 1:1 to either (1) an experimental intervention group, or (2) a conventional group (control). Over a 3-week time period immediately following baseline assessments and randomization, subjects in the experimental group will receive both immersive VR and conventional rehabilitation, while those in the control group will receive conventional rehabilitation only. During the rehabilitation period and over the following 12 weeks, upper extremity function, cognitive function, mental status, and daily living activity performance will be evaluated in the form of questionnaires. To trace brain reorganization in which upper extremity functions previously performed by ischemic-related brain areas are assumed by other brain areas, subjects will have brain scans immediately following enrollment but before randomization, immediately following the conclusion of rehabilitation, and 12 weeks after rehabilitation has concluded.

DISCUSSION

Effectiveness is assessed by evaluating motor improvement using the arm motor section of the Fugl-Meyer assessment. The study utilizes a cutting-edge brain neuroimaging approach to longitudinally trace the effectiveness of both VR-based and conventional training on stroke rehabilitation, which will hopefully describe the effects of the brain mechanisms of the intervention on recovery from stroke. Findings from the trial will greatly contribute to evidence on the use of immersive-VR-based training for stroke rehabilitation.

One-Quarter of People Leave Inpatient Stroke Rehabilitation with Physical Capacity for Community Ambulation

BACKGROUND AND PURPOSE

Ability to walk in the community is important for independence and participation in life roles, but is difficult for many people following stroke. The purpose of this study was to determine the proportion of people with stroke with the physical capacity to be independent community ambulators at discharge from a publicly funded inpatient rehabilitation setting.

METHOD

Consecutive medical records were audited to collate walking outcome at discharge, and to clarify if people with stroke had potential to walk independently in the community as defined by 4 criteria: independence with stairs; ability to traverse slopes and inclines; walking speed of .8m/s or more; and walking distance 367 m or higher on 6-Minute Walk Test.

RESULTS

While 80% of the 124 persons with stroke could walk indoors, only 27% could perform 4 essential skills needed to walk independently in the community at discharge from hospital. The proportion that met each criterion was 52% for stairs, 39% for slopes and inclines, 58% for speed, and 40% for distance. For the overall sample, mean (standard deviation) walking speed was .90 (.33) m/s, and distance for 6-Minute Walk Test was 349.6 (146.5) m.

DISCUSSION AND CONCLUSION

A retrospective review found that three quarters of stroke survivors lacked physical capacity for 4 skills required to walk independently in the community at the time of discharge from a public inpatient rehabilitation. Our findings recommend that people with stroke have access to outpatient physical rehabilitation to optimize walking outcome.

What do randomized controlled trials say about virtual rehabilitation in stroke? A systematic literature review and meta-analysis of upper-limb and cognitive outcomes

BACKGROUND

Virtual-reality based rehabilitation (VR) shows potential as an engaging and effective way to improve upper-limb function and cognitive abilities following a stroke. However, an updated synthesis of the literature is needed to capture growth in recent research and address gaps in our understanding of factors that may optimize training parameters and treatment effects.

METHODS

Published randomized controlled trials comparing VR to conventional therapy were retrieved from seven electronic databases. Treatment effects (Hedge's g) were estimated using a random effects model, with motor and functional outcomes between different protocols compared at the Body Structure/Function, Activity, and Participation levels of the International Classification of Functioning.

RESULTS

Thirty-three studies were identified, including 971 participants (492 VR participants). VR produced small to medium overall effects (g = 0.46; 95% CI: 0.33-0.59, p < 0.01), above and beyond conventional therapies. Small to medium effects were observed on Body Structure/Function (g = 0.41; 95% CI: 0.28-0.55; p < 0.01) and Activity outcomes (g = 0.47; 95% CI: 0.34-0.60, p < 0.01), while Participation outcomes failed to reach significance (g = 0.38; 95% CI: -0.29-1.04, p = 0.27). Superior benefits for Body Structure/Function (g = 0.56) and Activity outcomes (g = 0.62) were observed when examining outcomes only from purpose-designed VR systems. Preliminary results (k = 4) suggested small to medium effects for cognitive outcomes (g = 0.41; 95% CI: 0.28-0.55; p < 0.01). Moderator analysis found no advantage for higher doses of VR, massed practice training schedules, or greater time since injury.

CONCLUSION

VR can effect significant gains on Body Structure/Function and Activity level outcomes, including improvements in cognitive function, for individuals who have sustained a stroke. The evidence supports the use of VR as an adjunct for stroke rehabilitation, with effectiveness evident for a variety of platforms, training parameters, and stages of recovery.

EXERGAMES AS A TOOL FOR THE ACQUISITION AND DEVELOPMENT OF MOTOR SKILLS AND ABILITIES: A SYSTEMATIC REVIEW

Objective:

To analyze the literature on the effectiveness of exergames in physical education classes and in the acquisition and development of motor skills and abilities.

Data source:

The analyses were carried out by two independent evaluators, limited to English and Portuguese, in four databases: Web of Science, Science Direct, Scopus and PubMed, without restrictions related with year. The keywords used were: “Exergames and motor learning and motor skill” and “Exergames and motor skill and physical education”. The inclusion criteria were: articles that evaluated the effectiveness of exergames in physical education classes regarding the acquisition and development of motor skills. The following were excluded: books, theses and dissertations; repetitions; articles published in proceedings and conference summaries; and studies with sick children and/or use of the tool for rehabilitation purposes.

Data synthesis:

96 publications were found, and 8 studies were selected for a final review. The quality of the articles was evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) scale and the Physiotherapy Evidence Database (PEDro) scale. Evidence was found on the recurring positive effects of exergames in both motor skills acquisition and motor skills development.

Conclusions:

Exergames, when used in a conscious manner - so as to not completely replace sports and other recreational activities -, incorporate good strategies for parents and physical education teachers in motivating children and adolescents to practice physical exercise.

Trajectories of Stroke Care in Ontario: Which Path to Best Care?

BACKGROUND

Few studies have tracked stroke survivors through transitions across the health system and identified the most common trajectories and quality of care received. The objectives of our study were to examine the trajectories that incident stroke patients experience and to quantify the extent to which their care adhered to the best practices for stroke care.

METHODS

A population-based cohort of first-ever stroke/transient ischemic attack (TIA) patients from the 2012/13 Ontario Stroke Audit was linked to administrative databases using an encrypted health card number to identify dominant trajectories (N=12,362). All trajectories began in the emergency department (ED) and were defined by the transitions that followed immediately after the ED. Quality indicators were calculated to quantify best practice adherence within trajectories.

RESULTS

Six trajectories of stroke care were identified with significant variability in patient characteristics and quality of care received. Almost two-thirds (64.5%) required hospital admission. Trajectories that only involved the ED had the lowest rates of brain and carotid artery imaging (91.5 and 44.2%, respectively). Less than 20% of patients in trajectories involving hospital admissions received care on a stroke unit. The trajectory involving inpatient rehabilitation received suboptimal secondary prevention measures.

CONCLUSIONS

There are six main trajectories stroke patients follow, and adherence to best practices varies by trajectory. Trajectories resulting in patients being transitioned to home care following ED management only are least likely and those including inpatient rehabilitation are most likely to receive stroke best practices. Increased time in facility-based care results in greater access to best practices. Stroke patients receiving only ED care require closer follow-up by stroke specialists.

iPad Use in Stroke Neuro-Rehabilitation

Neuro-rehabilitation services are essential in reducing post-stroke impairments, enhancing independence, and improving recovery in hospital and post-discharge. However these services are therapist-dependent and resource intensive. Patients’ disengagement and boredom in stroke units are common which adversely affect functional and psychological outcomes. Novel techniques such as use of iPads™ are increasingly researched to overcome such challenges. The aim of this review is to determine the feasibility, effectiveness, acceptability, and barriers to the use of iPads™ in stroke neuro-rehabilitation. Four databases and manual literature search were used to identify published studies using the terms “iPad”, “Stroke”, and “neuro-rehabilitation”. Studies were included in accordance with the review selection criteria. A total of 16 articles were included in the review. The majority of the studies focused on iPads use in speech and language therapy. Although of small scale, the studies highlighted that iPads are feasible, have the potential to improve rehabilitation outcomes, and can improve patient’s social isolation. Patients’ stroke severity and financial limitations are some of the barriers highlighted in this review. This review presents preliminary data supportive for the use of iPad technology in stroke neuro-rehabilitation. However, further research is needed to determine impact on rehabilitation goals acquisition, clinical efficacy, and cost-efficiency.

Leap Motion-based virtual reality training for improving motor functional recovery of upper limbs and neural reorganization in subacute stroke patients

Virtual reality is nowadays used to facilitate motor recovery in stroke patients. Most virtual reality studies have involved chronic stroke patients; however, brain plasticity remains good in acute and subacute patients. Most virtual reality systems are only applicable to the proximal upper limbs (arms) because of the limitations of their capture systems. Nevertheless, the functional recovery of an affected hand is most difficult in the case of hemiparesis rehabilitation after a stroke. The recently developed Leap Motion controller can track the fine movements of both hands and fingers. Therefore, the present study explored the effects of a Leap Motion-based virtual reality system on subacute stroke. Twenty-six subacute stroke patients were assigned to an experimental group that received virtual reality training along with conventional occupational rehabilitation, and a control group that only received conventional rehabilitation. The Wolf motor function test (WMFT) was used to assess the motor function of the affected upper limb; functional magnetic resonance imaging was used to measure the cortical activation. After four weeks of treatment, the motor functions of the affected upper limbs were significantly improved in all the patients, with the improvement in the experimental group being significantly better than in the control group. The action performance time in the WMFT significantly decreased in the experimental group. Furthermore, the activation intensity and the laterality index of the contralateral primary sensorimotor cortex increased in both the experimental and control groups. These results confirmed that Leap Motion-based virtual reality training was a promising and feasible supplementary rehabilitation intervention, could facilitate the recovery of motor functions in subacute stroke patients. The study has been registered in the Chinese Clinical Trial Registry (registration number: ChiCTR-OCH-12002238).

A novel fuzzy approach for automatic Brunnstrom stage classification using surface electromyography

Clinical assessment plays a major role in post-stroke rehabilitation programs for evaluating impairment level and tracking recovery progress. Conventionally, this process is manually performed by clinicians using chart-based ordinal scales which can be both subjective and inefficient. In this paper, a novel approach based on fuzzy logic is proposed which automatically evaluates stroke patients' impairment level using single-channel surface electromyography (sEMG) signals and generates objective classification results based on the widely used Brunnstrom stages of recovery. The correlation between stroke-induced motor impairment and sEMG features on both time and frequency domain is investigated, and a specifically designed fuzzy kernel classifier based on geometrically unconstrained membership function is introduced in the study to tackle the challenges in discriminating data classes with complex separating surfaces. Experiments using sEMG data collected from stroke patients have been carried out to examine the validity and feasibility of the proposed method. In order to ensure the generalization capability of the classifier, a cross-validation test has been performed. The results, verified using the evaluation decisions provided by an expert panel, have reached a rate of success of the 92.47%. The proposed fuzzy classifier is also compared with other pattern recognition techniques to demonstrate its superior performance in this application.

A Further Step to Develop Patient-Friendly Implementation Strategies for Virtual Reality-Based Rehabilitation in Patients With Acute Stroke

BACKGROUND

Virtual reality (VR)-based rehabilitation is gaining attention as a way to promote early mobilization in patients with acute stroke. However, given the motor weakness and cognitive impairment associated with acute stroke, implementation strategies for overcoming patient-perceived difficulty need to be developed to enhance their motivation for training.

OBJECTIVE

The purpose of this study was to explore patient-perceived difficulty and enjoyment during VR-based rehabilitation and the factors affecting those experiences.

DESIGN

An exploratory mixed-method design was used in this study.

METHODS

Eight individuals with acute stroke participated in 2 training modes of VR-based rehabilitation (ie, workout and game modes) 20 to 30 minutes per day for 5 to 8 sessions. A visual analog scale was used to assess patient-perceived difficulty and enjoyment at every session. Then semistructured interviews were conducted to explore the factors affecting those experiences.

RESULTS

Levels of difficulty and enjoyment varied depending on the training mode and participants' phases of recovery. Five major factors were identified as affecting those varied experiences: (1) ease of following the directions, (2) experience of pain, (3) scores achieved, (4) novelty and immediate feedback, and (5) self-perceived effectiveness.

CONCLUSIONS

Levels of difficulty and enjoyment during VR-based rehabilitation differed depending on the phases of recovery and training mode. Therefore, graded implementation strategies for VR-based rehabilitation are necessary for overcoming patient-perceived difficulty and enhancing enjoyment. Ease of following the directions might be best considered in the very early stage, whereas multisensory feedback may be more necessary in the later stage. Health professionals also should find a way for patients to avoid pain during training. Feedback, such as knowledge of results and performance, should be used appropriately.

Smartphone-Based Visual Feedback Trunk Control Training Using a Gyroscope and Mirroring Technology for Stroke Patients: Single-blinded, Randomized Clinical Trial of Efficacy and Feasibility

OBJECTIVE

The purpose of this study was to assess the preliminary efficacy and feasibility of smartphone-based visual feedback trunk control training (SPVFTCT) for improving balance and trunk performance in stroke patients.

DESIGN

Twenty-four patients who had experienced a stroke more than 6 months previously and could sit and walk independently participated in the study. The participants were allocated to a SPVFTCT (n = 12) or to a control group (n = 12). Both groups completed five 80-minute sessions per week of conventional rehabilitation for 4 weeks. The SPVFTCT group additionally received three 20-minute sessions per week of SPVFTCT for 4 weeks. The outcome was assessed using static balance assessment, the modified functional reach test, the timed up and go test, and the trunk impairment scale. Feasibility of SPVFTCT was evaluated by retention, adherence, acceptability, and safety.

RESULTS

The static balance assessment, modified functional reach test, timed up and go test, and trunk impairment scale scores in the SPVFTCT group improved significantly compared to those in the control group (P < 0.05). In the SPVFTCT group, retention and adherence rates were 100% and 97%, respectively. All participants reported that SPVFTCT was enjoyable, easy to use, and helpful for their recovery.

CONCLUSIONS

The SPVFTCT approach is a feasible method to improve balance and trunk performance in stroke patients.

Efficacy and safety of non-immersive virtual reality exercising in stroke rehabilitation (EVREST): a randomised, multicentre, single-blind, controlled trial

BACKGROUND

Non-immersive virtual reality is an emerging strategy to enhance motor performance for stroke rehabilitation. There has been rapid adoption of non-immersive virtual reality as a rehabilitation strategy despite the limited evidence about its safety and effectiveness. Our aim was to compare the safety and efficacy of virtual reality with recreational therapy on motor recovery in patients after an acute ischaemic stroke.

METHODS

In this randomised, controlled, single-blind, parallel-group trial we enrolled adults (aged 18-85 years) who had a first-ever ischaemic stroke and a motor deficit of the upper extremity score of 3 or more (measured with the Chedoke-McMaster scale) within 3 months of randomisation from 14 in-patient stroke rehabilitation units from four countries (Canada [11], Argentina [1], Peru [1], and Thailand [1]). Participants were randomly allocated (1:1) by a computer-generated assignment at enrolment to receive a programme of structured, task-oriented, upper extremity sessions (ten sessions, 60 min each) of either non-immersive virtual reality using the Nintendo Wii gaming system (VRWii) or simple recreational activities (playing cards, bingo, Jenga, or ball game) as add-on therapies to conventional rehabilitation over a 2 week period. All investigators assessing outcomes were masked to treatment assignment. The primary outcome was upper extremity motor performance measured by total time to complete the Wolf Motor Function Test (WMFT) at the end of the 2 week intervention period, analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NTC01406912.

FINDINGS

The study was done between May 12, 2012, and Oct 1, 2015. We randomly assigned 141 patients: 71 received VRWii therapy and 70 received recreational activity. 121 (86%) patients (59 in the VRWii group and 62 in the recreational activity group) completed the final assessment and were included in the primary analysis. Each group improved WMFT performance time relative to baseline (decrease in median time from 43·7 s [IQR 26·1-68·0] to 29·7 s [21·4-45·2], 32·0% reduction for VRWii vs 38·0 s [IQR 28·0-64·1] to 27·1 s [21·2-45·5], 28·7% reduction for recreational activity). Mean time of conventional rehabilitation during the trial was similar between groups (VRWii, 373 min [SD 322] vs recreational activity, 397 min [345]; p=0·70) as was the total duration of study intervention (VRWii, 528 min [SD 155] vs recreational activity, 541 min [142]; p=0·60). Multivariable analysis adjusted for baseline WMFT score, age, sex, baseline Chedoke-McMaster, and stroke severity revealed no significant difference between groups in the primary outcome (adjusted mean estimate of difference in WMFT: 4·1 s, 95% CI -14·4 to 22·6). There were three serious adverse events during the trial, all deemed to be unrelated to the interventions (seizure after discharge and intracerebral haemorrhage in the recreational activity group and heart attack in the VRWii group). Overall incidences of adverse events and serious adverse events were similar between treatment groups.

INTERPRETATION

In patients who had a stroke within the 3 months before enrolment and had mild-to-moderate upper extremity motor impairment, non-immersive virtual reality as an add-on therapy to conventional rehabilitation was not superior to a recreational activity intervention in improving motor function, as measured by WMFT. Our study suggests that the type of task used in motor rehabilitation post-stroke might be less relevant, as long as it is intensive enough and task-specific. Simple, low-cost, and widely available recreational activities might be as effective as innovative non-immersive virtual reality technologies.

How does age affect the care dependency risk one year after stroke? A study based on claims data from a German health insurance fund

BACKGROUND

The objective of this study is to investigate the effect of age on care dependency risk 1 year after stroke. Two research questions are addressed: (1) How strong is the association between age and care dependency risk 1 year after stroke and (2) can this association be explained by burden of disease?

METHODS

The study is based on claims data from a German statutory health insurance fund. The study population was drawn from all continuously insured members with principal diagnoses of ischaemic stroke, hemorrhagic stroke, or transient ischaemic attack in 2007 who survived for 1 year after stroke and who were not dependent on care before their first stroke (n = 2864). Data were collected over a 1-year period. People are considered to be dependent on care if they, due to a physical, mental or psychological illness or disability, require substantial assistance in carrying out activities of daily living for a period of at least 6 months. Burden of disease was assessed by stroke subtype, history of stroke, comorbidities as well as geriatric multimorbidity. Regression models were used for data analysis.

RESULTS

21.6 % of patients became care dependent during the observation period. Post-stroke care dependency risk was significantly associated with age. Relative to the reference group (0-65 years), the odds ratio of care dependency was 11.30 (95 % CI: 7.82-16.34) in patients aged 86+ years and 5.10 (95 % CI: 3.88-6.71) in patients aged 76-85 years. These associations were not explained by burden of disease. On the contrary, age effects became stronger when burden of disease was included in the regression model (by between 1.1 and 28 %).

CONCLUSIONS

Our results show that age has an effect on care dependency risk that cannot be explained by burden of disease. Thus, there must be other underlying age-dependent factors that account for the remaining age effects (e.g., social conditions). Further studies are needed to explore the causes of the strong age effects observed.

The Effects of Game-Based Breathing Exercise on Pulmonary Function in Stroke Patients: A Preliminary Study

Background

Reduction of respiratory function along with hemiparesis leads to decreased endurance, dyspnea, and increased sedentary behavior, as well as to an increased risk of stroke. The main purpose of this study was to investigate the preliminary effects of game-based breathing exercise (GBE) on pulmonary function in stroke patients.

Material/Methods

Thirty-eight in-patients with stroke (22 men, 16 women) were recruited for the study. Participants were randomly allocated into 2 groups: patients assigned to the GBE group (n=19), and the control group (n=19). The GBE group participated in a GBE program for 25 minutes a day, 3 days a week, during a 5 week period. For the same period, both groups participated in a conventional stroke rehabilitation program. Forced vital capacity (FVC), forced expiratory volume at 1 second (FEV₁), FEV₁/FVC, and maximum voluntary ventilation (MVV) were measured by a spirometer in pre- and post-testing.

Results

The GBE group had significantly improved FVC, FEV_1, and MVV values compared with the control group (p<0.05), although there was no significant difference in FEV₁/FVC value between groups. Significant short-term effects of the GBE program on pulmonary function in stroke patients were recorded in this study.

Conclusions

These findings gave some indications that it may be feasible to include GBE in rehabilitation interventions with this population.

A Fuzzy Kernel Motion Classifier for Autonomous Stroke Rehabilitation

Autonomous poststroke rehabilitation systems which can be deployed outside hospital with no or reduced supervision have attracted increasing amount of research attentions due to the high expenditure associated with the current inpatient stroke rehabilitation systems. To realize an autonomous systems, a reliable patient monitoring technique which can automatically record and classify patient's motion during training sessions is essential. In order to minimize the cost and operational complexity, the combination of nonvisual-based inertia sensing devices and pattern recognition algorithms are often considered more suitable in such applications. However, the high motion irregularity due to stroke patients' body function impairment has significantly increased the classification difficulty. A novel fuzzy kernel motion classifier specifically designed for stroke patient's rehabilitation training motion classification is presented in this paper. The proposed classifier utilizes geometrically unconstrained fuzzy membership functions to address the motion class overlapping issue, and thus, it can achieve highly accurate motion classification even with poorly performed motion samples. In order to validate the performance of the classifier, experiments have been conducted using real motion data sampled from stroke patients with a wide range of impairment level and the results have demonstrated that the proposed classifier is superior in terms of error rate compared to other popular algorithms.

Demographics and discharge outcomes of dysvascular and non-vascular lower limb amputees at a subacute rehabilitation unit: a 7-year series

Objective To examine personal and social demographics, and rehabilitation discharge outcomes of dysvascular and non-vascular lower limb amputees. Methods In total, 425 lower limb amputation inpatient rehabilitation admissions (335 individuals) from 2005 to 2011 were examined. Admission and discharge descriptive statistics (frequency, percentages) were calculated and compared by aetiology. Results Participants were male (74%), aged 65 years (s.d. 14), born in Australia (72%), had predominantly dysvascular aetiology (80%) and a median length of stay 48 days (interquartile range (IQR): 25–76). Following amputation, 56% received prostheses for mobility, 21% (n = 89) changed residence and 28% (n = 116) required community services. Dysvascular amputees were older (mean 67 years, s.d. 12 vs 54 years, s.d. 16; P < 0.001) and recorded lower functional independence measure – motor scores at admission (z = 3.61, P < 0.001) and discharge (z = 4.52, P < 0.001). More non-vascular amputees worked before amputation (43% vs 11%; P < 0.001), were prescribed a prosthesis by discharge (73% vs 52%; P < 0.001) and had a shorter length of stay (7 days, 95% confidence interval: –3 to 17), although this was not statistically significant. Conclusions Differences exist in social and demographic outcomes between dysvascular and non-vascular lower limb amputees. What is known about the topic? Lower limb amputation occurs due to various aetiologies. What does this paper add? Lower limb amputee rehabilitation over 7 years was investigated, comprising 425 admissions, 80% due to dysvascular aetiology. Personal and social demographics, and discharge outcomes are compared by aetiology. What are the implications for practitioners? Demographic and discharge outcome differences exist between dysvascular and non-vascular lower limb amputees. Twenty-one percent were required to change residence and 28% required additional social supports. Discharge planning should begin as soon as possible to limit time spent waiting for new accommodation or major modifications for current homes. Lower limb amputees are not homogeneous, so care should be taken if extrapolating from combined amputee aetiologies or from one aetiology to another.

iPad technology for home rehabilitation after stroke (iHOME): a proof-of-concept randomized trial

BACKGROUND

Tablets are a novel line of computers controlled by a multitouch screen. Fine motor movements are captured on the tablet computer through electrical fields and can be qualitatively and quantitatively assessed. Evidence is limited on tablet use for stroke rehabilitation.

METHODS

iHOME is an investigator-initiated randomized controlled pilot trial with a single-blinded outcome assessment. The intervention consists of iPad use (investigational group) vs. usual care (control group) among patients receiving conventional outpatient rehabilitation. Eligibility includes aged 18-85 years who experienced a mild ischemic or hemorrhagic stroke (as diagnosed on neuroimaging and determined by the Chedoke-McMaster score ≥3. The STROKE REHAB® software for the iPad was specifically designed for patients with fine motor weakness and/or neglect. Of the total 30 patients, 20 will be in iHOME Acute (enrolled within three-months of stroke onset) and 10 patients in iHOME Chronic (enrolled more than six-months from onset).

OUTCOME MEASURES

The primary feasibility outcome is the proportion of the scheduled iPad time used (more than 70% (≥140 mins) of the total 'dose' of intervention intended will be considered successful). Efficacy in fine motor movements will be assessed using the nine-hole peg test; time to magnify and pop the balloons in the iPad software application, and improvement in Wolf Motor Function Test.

CONCLUSIONS

iHOME is a randomized controlled trial assessing the feasibility, safety, and efficacy of tablet technology for home use in stroke rehabilitation. The results of this study will serve as the basis for a larger multicenter trial.

Activity limitations experienced by people with stroke who receive inpatient rehabilitation: differences between 2001, 2005, and 2011

OBJECTIVE

To determine whether there were differences in characteristics and activity limitations relevant to physiotherapists among people receiving inpatient rehabilitation after stroke in 2001, 2005, and 2011.

DESIGN

A multicenter observational study of 3 periods.

SETTING

Inpatient rehabilitation units (N=15).

PARTICIPANTS

Adult stroke survivors (N=738) admitted over 3 periods (2001, 2005, 2011).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Characteristics, hospital metrics, and Motor Assessment Scale (MAS) scores were recorded on admission and discharge.

RESULTS

All 3 cohorts were similar in terms of sex, side affected by stroke, and length of time from stroke onset to rehabilitation admission. Stroke participants in the 2005 cohort were older than those in the 2011 and 2001 cohorts. Participants in the 2011 cohort had a longer inpatient rehabilitation length of stay, experienced lower average MAS gains per day (F>3.298, P<.038), and experienced more activity limitations in basic functional tasks involving bed mobility, standing up, and sitting balance on admission and discharge, and in walking and arm function at discharge only compared with earlier cohorts.

CONCLUSIONS

In 2011, on average, people admitted for rehabilitation after stroke were approximately the same age as patients in 2005 and 2001 and it took approximately 2 weeks for all of these patients to be admitted to a rehabilitation unit, but patients in 2011 had a longer inpatient rehabilitation length of stay compared with patients in 2005 and 2001. In addition, activity limitations at inpatient rehabilitation admission and discharge appear to be worse, particularly for activities such as rolling, sitting up over the edge of the bed, and balanced sitting.

FCET2EC (From controlled experimental trial to = 2 everyday communication): How effective is intensive integrative therapy for stroke-induced chronic aphasia under routine clinical conditions? A study protocol for a randomized controlled trial

BACKGROUND

Therapy guidelines recommend speech and language therapy (SLT) as the "gold standard" for aphasia treatment. Treatment intensity (i.e., ≥5 hours of SLT per week) is a key predictor of SLT outcome. The scientific evidence to support the efficacy of SLT is unsatisfactory to date given the lack of randomized controlled trials (RCT), particularly with respect to chronic aphasia (lasting for >6 months after initial stroke). This randomized waiting list-controlled multi-centre trial examines whether intensive integrative language therapy provided in routine in- and outpatient clinical settings is effective in improving everyday communication in chronic post-stroke aphasia.

METHODS/DESIGN

Participants are men and women aged 18 to 70 years, at least 6 months post an ischemic or haemorrhagic stroke resulting in persisting language impairment (i.e., chronic aphasia); 220 patients will be screened for participation, with the goal of including at least 126 patients during the 26-month recruitment period. Basic language production and comprehension abilities need to be preserved (as assessed by the Aachen Aphasia Test).Therapy consists of language-systematic and communicative-pragmatic exercises for at least 2 hours/day and at least 10 hours/week, plus at least 1 hour self-administered training per day, for at least three weeks. Contents of therapy are adapted to patients' individual impairment profiles.Prior to and immediately following the therapy/waiting period, patients' individual language abilities are assessed via primary and secondary outcome measures. The primary (blinded) outcome measure is the A-scale (informational content, or 'understandability', of the message) of the Amsterdam-Nijmegen Everyday Language Test (ANELT), a standardized measure of functional communication ability. Secondary (unblinded) outcome measures are language-systematic and communicative-pragmatic language screenings and questionnaires assessing life quality as viewed by the patient as well as a relative.The primary analysis tests for differences between the therapy group and an untreated (waiting list) control group with respect to pre- versus post 3-week-therapy (or waiting period, respectively) scores on the ANELT A-scale. Statistical between-group comparisons of primary and secondary outcome measures will be conducted in intention-to-treat analyses.Long-term stability of treatment effects will be assessed six months post intensive SLT (primary and secondary endpoints).

Biofeedback in rehabilitation

This paper reviews the literature relating to the biofeedback used in physical rehabilitation. The biofeedback methods used in rehabilitation are based on biomechanical measurements and measurements of the physiological systems of the body. The physiological systems of the body which can be measured to provide biofeedback are the neuromuscular system, the respiratory system and the cardiovascular system. Neuromuscular biofeedback methods include electromyography (EMG) biofeedback and real-time ultrasound imaging (RTUS) biofeedback. EMG biofeedback is the most widely investigated method of biofeedback and appears to be effective in the treatment of many musculoskeletal conditions and in post cardiovascular accident (CVA) rehabilitation. RTUS biofeedback has been demonstrated effective in the treatment of low back pain (LBP) and pelvic floor muscle dysfunction. Cardiovascular biofeedback methods have been shown to be effective in the treatment of a number of health conditions such as hypertension, heart failure, asthma, fibromyalgia and even psychological disorders however a systematic review in this field has yet to be conducted. Similarly, the number of large scale studies examining the use of respiratory biofeedback in rehabilitation is limited. Measurements of movement, postural control and force output can be made using a number of different devices and used to deliver biomechanical biofeedback. Inertial based sensing biofeedback is the most widely researched biomechanical biofeedback method, with a number of studies showing it to be effective in improving measures of balance in a number of populations. Other types of biomechanical biofeedback include force plate systems, electrogoniometry, pressure biofeedback and camera based systems however the evidence for these is limited. Biofeedback is generally delivered using visual displays, acoustic or haptic signals, however more recently virtual reality (VR) or exergaming technology have been used as biofeedback signals. VR and exergaming technology have been primarily investigated in post-CVA rehabilitation, however, more recent work has shown this type of biofeedback to be effective in improving exercise technique in musculoskeletal populations. While a number of studies in this area have been conducted, further large scale studies and reviews investigating different biofeedback applications in different clinical populations are required.

Who receives rehabilitation after stroke?: Data from the quality assurance project "Stroke Register Northwest Germany"

BACKGROUND

Neurological rehabilitation after stroke lowers rates of death, dependency, and institutionalization. Little research has yet addressed the factors affecting the selection of ischemic stroke patients for rehabilitative treatment.

METHOD

The database for this study consisted of all cases of ischemic stroke (ICD-10 code I63) that occurred in 2010 and 2011 in the neurological inpatient care facilities participating in the "Stroke Register Northwest Germany" quality assurance project. A primary target group for rehabilitation was defined a priori (Barthel Index at discharge ≤ 65, no premorbid nursing dependency, no transfer to another acute-care hospital after initial treatment of stroke). Among these patients, factors potentially affecting the provision of rehabilitative treatment were studied with binary logistic regression and multilevel logistic regression.

RESULTS

There were 96 955 cases of ischemic stroke in the 127 participating hospitals. 40.8% and 11.4% of these patients underwent neurological and geriatric rehabilitation, respectively. The primary target group for rehabilitation contained 14 486 patients, 14.9% of whom underwent no rehabilitation after their acute treatment. The chances of undergoing subsequent rehabilitation were higher for patients with paresis and dysarthria on admission. Female sex, older age, impaired consciousness at admission, prior history of stroke, and lack of counseling by the hospital social services were all associated with a lower probability of undergoing rehabilitation.

CONCLUSION

In this study, 54.4% of all ischemic stroke patients and 85.1% of all patients in a primary target group for rehabilitation that was defined a priori underwent rehabilitation after acute care for stroke. Older patients and those who had had a previous stroke were less likely to undergo rehabilitation. Counseling by hospital social services increased the probability of rehabilitation. The potential exclusion of stroke patients from rehabilitation because of old age should be critically examined in every relevant case.
