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.

Consensus Statement on Neurorehabilitation during COVID-19 Times: Expert Group on Behalf of the Indian Federation of Neurorehabilitation (IFNR)

The COVID19 pandemic in India is causing significant morbidity and disruptions of healthcare delivery. The rapidly escalating contagion is straining our public health system, which is already under pressure due to a shortage of infrastructure and inadequate workforce. Neuro rehabilitation services that are still in its infancy in our country have been significantly interrupted in the last six months. An expert group from Indian Federation of Neurorehabilitation (IFNR) have formulated the guidelines and consensus recommendations for Neurologists, Physiatrists, and Therapists managing neurological disabilities during COVID 19. The aim of this consensus paper is to sensitize the clinicians and therapists about maintaining the continuum of care and rehabilitation needs of Covid patients as well as non Covid patients with neurological disorders during the ongoing COVID 19 pandemic.

Gait training interventions for patients with stroke in India: A systematic review

BACKGROUND

Gait is considered to be the most important determinant of functional independence in activities of daily living. The challenges faced by stroke survivors in India differ from the western population due to economic, cultural, and geographical factors and this, in turn, may influence the choice of intervention. Hence, there is a need to understand the current gait training trends for stroke survivors in low resource settings like India.

RESEARCH QUESTION

To systematically review the literature on interventional strategies for improving gait among stroke survivors in India.

METHODS

Six databases were searched to identify RCTs delivering gait training to stroke survivors having some gait deficits in terms of speed or any other kinematic parameters. Studies of the English language from India were included. Two independent reviewers screened, extracted data, and assessed the study quality. A descriptive synthesis was undertaken and the data was summarized.

RESULTS

Of 2112 potentially relevant articles, 12 studies with a total of 412 participants were included after title, abstract and full-text screening. Studies tested the efficacy of interventions such as mirror therapy, motor imagery, transcutaneous electrical nerve stimulation, strengthening, and task-based training. The outcome measures were kinematic gait-analysis, gait velocity, Functional Ambulation Categories, Timed Up and Go, Fugl-Meyer Assessment. From the results of this review, active task-based gait training and strengthening along with motor priming seems to be the most tested interventions. Future studies may need to design interventions targeting both impairment and function to bring about maximum improvement in gait after stroke.

SIGNIFICANCE

Reviews addressing gait practices in developing countries for people with stroke are scarce. The present review would assist physiotherapists in developing countries to utilize evidence-based criteria for the selection of gait training approaches post-stroke. Due to the environmental and contextual demands, the effect of interventions for recovery among stroke survivors should be improvised in low resource settings. This review can be a source of recommendation in giving effective strategies for clinical practice.

How does context influence arm use after stroke? A qualitative content analysis among rural community-dwelling stroke survivors

OBJECTIVE

To explore the personal and environmental contextual factors that influence use of affected arm for function among stroke survivors.

METHODS

We conducted a qualitative phenomenological study using an interpretivist paradigm among 23 stroke survivors in their late sub-acute and chronic stages and their relatives living in the rural regions of India using maximum variation sampling. Semi-structured interviews were conducted to identify personal and environmental contextual factors relevant to arm use. Their current level of arm use, motor and functional ability were evaluated using Motor Activity Log, AbilHand and Lawton Instrumental Activities of Daily Living scales and the scores were categorized in order to describe and compare the participant's characteristics before analyzing each interview. Differences among the contextual factors of participants with high and low levels of functional arm use and exercise using paretic limb were analyzed using qualitative content analysis.

RESULTS

Study participants followed active exercises or passive interventions to improve their arm. Their immediate social environment influenced these decisions. Lack of awareness on how to self-engage or scale down their physical environment to match their abilities demoted active functional task performance. Ability to perceive small gains in arm function helped them sustain their efforts.

CONCLUSION

Context influences arm use. Addressing contextual determinants influencing arm use such as facilitating understanding about the need for active functional task engagement; identifying and addressing factors moderating motivation to sustain functional task practice and enriching objects to match their movement abilities can increase arm use and promote upper limb recovery.

Relationship Between Spasticity and Upper-Limb Movement Disorders in Individuals With Subacute Stroke Using Stochastic Spatiotemporal Modeling

BACKGROUND

Spasticity is common in patients with stroke, yet current quantification methods are insufficient for determining the relationship between spasticity and voluntary movement deficits. This is partly a result of the effects of spasticity on spatiotemporal characteristics of movement and the variability of voluntary movement. These can be captured by Gaussian mixture models (GMMs).

OBJECTIVES

To determine the influence of spasticity on upper-limb voluntary motion, as assessed by the bidirectional Kullback-Liebler divergence (BKLD) between motion GMMs.

METHODS

A total of 16 individuals with subacute stroke and 13 healthy aged-equivalent controls reached to grasp 4 targets (near-center, contralateral, far-center, and ipsilateral). Two-dimensional GMMs (angle and time) were estimated for elbow extension motion. BKLD was computed for each individual and target, within the control group and between the control and stroke groups. Movement time, final elbow angle, average elbow velocity, and velocity smoothness were computed.

RESULTS

Between-group BKLDs were much larger than within control-group BKLDs. Between-group BKLDs for the near-center target were lower than those for the far-center and contralateral targets, but similar to that for the ipsilateral target. For those with stroke, the final angle was lower for the near-center target, and the average velocity was higher. Velocity smoothness was lower for the near-center than for the ipsilateral target. Elbow flexor and extensor passive muscle resistance (Modified Ashworth Scale) strongly explained BKLD values.

CONCLUSIONS

Results support the view that individuals with poststroke spasticity have a velocity-dependent reduction in active elbow joint range and that BKLD can be used as an objective measure of the effects of spasticity on reaching kinematics.

Effectiveness of a multifactorial context-enhancing functional therapy to promote functional arm use and recovery of stroke survivors: study protocol for a clinical trial

INTRODUCTION

After a stroke, 55% of survivors do not regain the ability to completely use their arm in daily life functioning. Currently, evidence-based guidelines recommend functional training for improving the affected hand after stroke. However, promoting an optimal quantity and quality of functional training is influenced by personal and environmental contextual factors. Studies that comprehensively target multiple factors regulating arm use are limited. This study compares the effects of functional training to multifactorial context-enhancing functional training program for improving functional arm use and recovery after stroke.

METHODS AND ANALYSIS

This is a protocol for an observer-blinded, two parallel groups, randomised controlled trial. A total of 126 community-dwelling subacute and chronic stroke survivors will be included in the study. A tailor-made multifactorial context-enhancing intervention-incorporating education, environmental enrichment and behaviour change techniques to reinforce functional training will be provided to the experimental group. The functional training group will be provided with functional exercises. The intervention will be delivered for 2 months. The primary outcomes of functional arm use and recovery will be measured using Motor Activity Log, Goal Attainment Scale and Rating of Everyday Arm-use in the Community and Home scale. The secondary outcomes of arm motor impairment and function will be measured using Fugl-Meyer upper limb score, Action Research Arm Test, ABILHAND questionnaire and Stroke Impact Scale. These will be measured at three points in time: before, after 2 months and after 1-month follow-up. The outcome measures will be analysed using one-way analysis of variance and regression analysis will be performed to identify factors limiting optimal task practice.

ETHICS AND DISSEMINATION

The study has been approved by the Institutional Ethics Committee of Kasturba Hospital, Manipal, India. Participants will sign a written informed consent prior to participation. The results will be published on completion of the trial and communicated to community-dwelling stroke survivors.

Improving life after stroke needs global efforts to implement evidence-based physical activity pathways

There is an urgent need to improve life after stroke across the world-especially in low-income countries-through methods that are effective, equitable and sustainable. This paper highlights physical activity (PA) as a prime candidate for implementation. PA reduces modifiable risk factors for first and recurrent stroke and improves function and activity during rehabilitation and following discharge. Preliminary evidence also indicates PA is cost-effective. This compelling evidence urgently needs to be translated into seamless pathways to enable stroke survivors across the world to engage in a more active lifestyle. Although more quality research is needed-particularly on how to optimize uptake and maintenance of PA-this should not delay implementation of high-quality evidence already available. This paper shares examples of best practice service models from low-, middle-, and high-income countries around the world. The authors call for a concerted effort to implement high-quality PA services to improve life after stroke for all.

Bringing stroke clinical guidelines to life

Clinical practice guidelines are essential for driving evidence-based clinical care to patients. In an era of ever-increasing research evidence, keeping guidelines up to date is a challenging and resource-intensive process. Advances in technological platforms provide opportunities to develop new models of guideline development that will allow for continuous, rapid updates to recommendations as new evidence emerges. As Australia and other countries begin to develop these models, we have an opportunity to work more closely together to ensure the most efficient use of resources.

Comparison of transcutaneous electrical nerve stimulation (TENS) and functional electrical stimulation (FES) for spasticity in spinal cord injury - A pilot randomized cross-over trial

OBJECTIVE

Spasticity following spinal cord injury (SCI) can impair function and affect quality of life. This study compared the effects of transcutaneous electrical nerve stimulation (TENS) and functional electrical stimulation (FES) on lower limb spasticity in patients with SCI.

DESIGN

Double blind randomized crossover design.

SETTING

Neuro-rehabilitation unit, Manipal University, India.

PARTICIPANTS

Ten participants (age: 39 ± 13.6 years, C1-T11, 1-26 months post SCI) with lower limb spasticity were enrolled in this study.

INTERVENTIONS

Participants were administered electrical stimulation with TENS and FES (duration - 30 minutes) in a cross over manner separated by 24 hours.

OUTCOME MEASURES

Spasticity was measured using modified Ashworth scale (MAS) [for hip abductors, knee extensors and ankle plantar flexors] and spinal cord assessment tool for spastic reflexes (SCATS). Assessments were performed at baseline, immediately, 1 hour, 4 hours, and 24 hours post intervention.

RESULTS

A between group analysis did not show statistically significant differences between FES and TENS (P > 0.05). In the within group analyses, TENS and FES significantly reduced spasticity up to 4 hours in hip adductors and knee extensors (P < 0.01). SCATS values showed significant reductions at 1 hour (P = 0.01) following TENS and 4 hours following FES (P = 0.01).

CONCLUSION

A single session of electrical stimulation with FES and TENS appears to have similar anti-spasticity effects that last for 4 hours. The findings of this preliminary study suggest that both TENS and FES have the potential to be used as therapeutic adjuncts to relieve spasticity in the clinic. In addition, FES may have better effects on patients presenting with spastic reflexes.

Efficacy of Trunk Regimes on Balance, Mobility, Physical Function, and Community Reintegration in Chronic Stroke: A Parallel-Group Randomized Trial

OBJECTIVE

The study objective was to examine the efficacy of plinth and Swiss ball-based trunk exercise regimes on balance, mobility, physical function, and community reintegration compared with standard physiotherapy in chronic stroke.

SUBJECTS AND METHODS

This observer-blinded parallel-group randomized trial was conducted in outpatient stroke units. People with chronic stroke aged between 30 and 75 years, first onset of unilateral cortical lesion, poor trunk performance, 10 m independent walking ability with or without walking aids, and absence of pusher syndrome were included. Trunk Impairment Scale 2.0, Brunel Balance Assessment, Tinetti scale, gait speed, Stroke Impact Scale-16, and Reintegration to Normal Living Index were the measures. Experimental interventions involved the practice of selective upper and lower trunk movements using either plinth or Swiss ball. Control group received standard physiotherapy. All the patients practiced 1 hour exercise session, 3 sessions a week over a duration of 6 weeks and followed up after 3 and 12 months.

RESULTS

Of 108 patients allocated into 3 groups, baseline characteristics were similar. Postintervention compared with control group, the plinth, and Swiss ball groups showed significant mean changes in the outcome measures: trunk impairment scale 2.0 (3.6;4.1 points), Brunel Balance Assessment (1-level), Tinetti scale (5;5.2 points), gait speed (.06;.08 m/s), Stroke Impact Scale-16 (8.7;7.2 points), and community reintegration (7.6;8.8 points). These improvements were retained during 3-12 months' follow-up. Statistical significant was set at P < .05.

CONCLUSION

Plinth and Swiss ball-based trunk exercise regimes showed significant improvements in balance, mobility, physical function, and community reintegration in chronic stroke as against standard physiotherapy.

Frequency and Factors Associated With Honorary Authorship in Indian Biomedical Journals: Analysis of Papers Published From 2012 to 2013

Honorary authorship is the inclusion of an author on an article whose contribution does not warrant authorship. We conducted an Internet-based survey among first authors publishing in Indian biomedical journals from 2012 to 2013 to study the frequency and factors associated with honorary authorship. The response rate was 27% (245/908) with the prevalence of perceived, International Committee of Medical Journal Editors (ICMJE)-defined, and unperceived honorary authorship of 20.9% (50/239), 60% (147/245), and 46.9% (115/245), respectively. Those residing in India were found to list more honorary authors. We hope to increase awareness of the ICMJE authorship guidelines and the general issue of honorary authorship among researchers in India and elsewhere.

Personalized upper limb training combined with anodal-tDCS for sensorimotor recovery in spastic hemiparesis: study protocol for a randomized controlled trial

Background

Recovery of voluntary movement is a main rehabilitation goal. Efforts to identify effective upper limb (UL) interventions after stroke have been unsatisfactory. This study includes personalized impairment-based UL reaching training in virtual reality (VR) combined with non-invasive brain stimulation to enhance motor learning. The approach is guided by limiting reaching training to the angular zone in which active control is preserved (“active control zone”) after identification of a “spasticity zone”. Anodal transcranial direct current stimulation (a-tDCS) is used to facilitate activation of the affected hemisphere and enhance inter-hemispheric balance. The purpose of the study is to investigate the effectiveness of personalized reaching training, with and without a-tDCS, to increase the range of active elbow control and improve UL function.

Methods

This single-blind randomized controlled trial will take place at four academic rehabilitation centers in Canada, India and Israel. The intervention involves 10 days of personalized VR reaching training with both groups receiving the same intensity of treatment. Participants with sub-acute stroke aged 25 to 80 years with elbow spasticity will be randomized to one of three groups: personalized training (reaching within individually determined active control zones) with a-tDCS (group 1) or sham-tDCS (group 2), or non-personalized training (reaching regardless of active control zones) with a-tDCS (group 3). A baseline assessment will be performed at randomization and two follow-up assessments will occur at the end of the intervention and at 1 month post intervention. Main outcomes are elbow-flexor spatial threshold and ratio of spasticity zone to full elbow-extension range. Secondary outcomes include the Modified Ashworth Scale, Fugl-Meyer Assessment, Streamlined Wolf Motor Function Test and UL kinematics during a standardized reach-to-grasp task.

Discussion

This study will provide evidence on the effectiveness of personalized treatment on spasticity and UL motor ability and feasibility of using low-cost interventions in low-to-middle-income countries.

Current Practices of Physical and Occupational Therapists Regarding Spasticity Assessment and Treatment

Purpose: The purpose of this study was to understand current trends in rehabilitation practice regarding spasticity assessment and treatment. Method: The clinical practices of Canadian physiotherapists and occupational therapists in assessing and treating spasticity were investigated using a self-administered, Web-based questionnaire (cross-sectional design). Experienced clinicians developed the questionnaire, which surveyed socio-demographic characteristics, work environment, and clinician satisfaction with spasticity assessments and preferences for treatment. Results: A total of 317 clinicians (204 physiotherapists and 113 occupational therapists) completed the questionnaire. The majority of participants reported that using valid and reliable outcome measures to assess spasticity was important (91.1%). Most clinicians indicated using a combination of spasticity assessments, and their level of satisfaction with these assessments was very high. All clinicians believed that spasticity should be evaluated by rehabilitation professionals, and most indicated that it should be assessed by more than one professional. Although 83.8% indicated that spasticity should be tested on admission, a much lower percentage believed that it should be evaluated throughout rehabilitation. Most clinicians (92.2%) reported using multiple treatment modalities for spasticity. Conclusions: This study is the first to document clinicians' practices regarding spasticity assessment and treatment. A better understanding of current trends in physiotherapy and occupational therapy will help in tailoring strategies to improve practice.

Cervicobrachial pain - How Often is it Neurogenic?

INTRODUCTION

Neck pain associated with pain in the arm (cervicobrachial pain) is a common complaint in patients seeking physiotherapy management. The source of symptoms for this complaint is commonly presumed to be neural. However, this pain pattern could also result from various other innervated tissue structures of the upper quarter. Knowledge about frequency of neural structures being a predominant source of symptoms would help in implementing appropriate therapeutic strategies such as neural tissue mobilization along with other complimentary therapies for optimal outcomes.

AIM

To determine the frequency of cervicobrachial pain being neurogenic.

MATERIALS AND METHODS

Participants (n=361) aged between 20-65 years, reporting cervicobrachial pain were screened for neurogenic nature of symptoms. These physical signs included: active and passive movement dysfunction, adverse responses to neural tissue provocation tests, tenderness on palpating nerve trunks and related cutaneous tissues and evidence of a related local area of pathology (Clinical/radiological). The consistency of all these signs was checked to identify a significant neural involvement.

RESULTS

Descriptive statistics were used to analyse data. Of 361 participants, 206 were males (44.6 ±10.8 years) and 155 were females (41.8 ± 11.2 years). The frequency of neurogenic cervicobrachial pain was determined to be 19.9% (n=72) and the non-neurogenic sources for symptoms were attributed to 80.1% (n=289) of screened participants.

CONCLUSION

Lower frequency of cervicobrachial pain being neurogenic indicates thorough screening for appropriate therapeutic interventions to be successful.

Can response time be trained with bilateral limb training in children with Down syndrome?

Aims:

Response time (RT), that is, the time taken to respond is known to be delayed in children with Down syndrome (DS). We performed a pilot study to evaluate whether bilateral limb training can be used to train RT, in children with DS.

Settings and Design:

10 children with DS (5 males) were recruited from a special school in a suburban region using convenience sampling.

Subjects and Methods:

Response time was measured using an indigenously developed RT Analyzer, before and after intervention, from right and left hand. Structured bilateral limb training was given for a period of 4 weeks, using low-cost, locally available materials, in community settings.

Statistical Analysis Used:

The Wilcoxon signed ranks test was used for statistical analysis.

Results:

Significant improvements in RT following 4 weeks of intervention were seen in the left hand (P = 0.006) but not in the right hand (P = 0.104).

Conclusions:

Response time can be trained in children with DS using 4 weeks of bilateral limb training activities using low-cost, locally available materials.

Interferon-beta-1b effects on re-enhancing lesions in patients with multiple sclerosis

Interferon-beta (IFNbeta) reduces the number and load of new contrast-enhancing lesions (CELs) in patients with multiple sclerosis (MS). However, the ability of IFNbeta to reduce lesion sizes and re-enhancements of pre-existing CELs has not been examined extensively. Activity of contrast re-enhancing lesions (Re-CELs) and contrast single-enhancing lesions (S-CELs) were monitored in ten patients with relapsing-remitting (RR) MS. These patients underwent monthly post-contrast magnetic resonance imaging (MRIs) for an 18-month natural history phase and an 18-month therapy phase with subcutaneous IFNbeta-1b, totaling 37 images per patient. The activity was analysed using the first image as a baseline and registering subsequent active monthly images to the baseline. There was a 76.4% reduction in the number of CELs with IFNbeta therapy. The decrease was greater (P = 0.003) for S-CELs (82.3%) than for Re-CELs (57.4%). S-CELs showed no changes in durations of enhancement and maximal lesion sizes with treatment. Exclusively for Re-CELs, IFNbeta-1b significantly decreased maximal lesion sizes, total number of enhancement periods and total months of enhancement. Thus, IFNbeta appears to be effective in reducing the degree of severity of inflammation among Re-CELs, as reflected by their reduced maximal lesion sizes and durations of enhancement.
