Motor recovery beginning 23 years after ischemic stroke

It is widely believed that most stroke recovery occurs within 6 mo, with little benefit of physiotherapy or other modalities beyond 1 yr. We report a remarkable case of stroke recovery beginning 23 yr after a severe stroke due to embolization from the innominate artery and subclavian artery, resulting from compression of the right subclavian artery by a cervical rib. The patient had a large right frontoparietal infarction with severe left hemiparesis and a totally nonfunctional spastic left hand. He experienced some recovery of hand function that began 23 yr after the stroke, 1 yr after he took up regular swimming. As a result, intensive physiotherapy was initiated, with repetitive large muscle movement and a spring-loaded mechanical orthosis that provides resistance to finger flexors and supports finger extensors. Within 2 yr, he could pick up coins with the previously useless left hand. Functional MRI studies document widespread distribution of the recovery in both hemispheres. This case provides impetus not only to more intensive and prolonged physiotherapy, but also to treatment with emerging modalities such as stem cell therapy and exosome and microRNA therapies. NEW & NOTEWORTHY Widespread bilateral activation of both sides of the cerebrum and cerebellum are demonstrated on functional MRI after motor recovery of a completely nonfunctional left hand that began 23 yr after a severe stroke. This suggests that the generally accepted window of recovery beyond which further therapy is not indicated should be entirely reconsidered. Physiotherapy and new modalities in development might be indicated long after a stroke

State-of-the-art clinical assessment of hand function

We have assembled a multi-disciplinary team of engineers, surgeons, clinicians and neuroscientists from Johns Hopkins School of Medicine and Western University to develop a new device for assessing hand function. It will be capable of sensitively measuring fingertip forces across all five fingers and along all movement directions. Then we can use this device to develop and validate a clinical hand assessment for patients with brain injuries.https://ir.lib.uwo.ca/brainscanprojectsummaries/1005/thumbnail.jp

The Creative Commons Public Domain Dedication waiver ( http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise stated.Background Acquired brain injury (ABI) is the leading cause of disability worldwide yet there is little information regarding the most effective way to organise ABI health care services. The aim of this review was to identify the most up-to-date high quality evidence to answer specific questions regarding the organisation of health care services for people with an ABI. Methods We conducted a systematic review of English papers using MEDLINE, EMBASE, PsycINFO, CINAHL and the Cochrane Library. We included the most recently published high quality systematic reviews and any randomised controlled trials, non-randomised controlled trials, controlled before after studies or interrupted time series studies published subsequent to the systematic review. We searched for papers that evaluated pre-defined organisational interventions for adults with an ABI. Organisational interventions of interest included fee-for-service care, integrated care, integrated care pathways, continuity of care, consumer engagement in governance and quality monitoring interventions. Data extraction and appraisal of included reviews and studies was completed independently by two reviewers. Results A total of five systematic reviews and 21 studies were included in the review; eight of the papers (31%) included people with a traumatic brain injury (TBI) or ABI and the remaining papers (69%) included only participants with a diagnosis of stroke. We found evidence supporting the use of integrated care to improve functional outcome and reduce length of stay and evidence supporting early supported discharge teams for reducing morbidity and mortality and reducing length of stay for stroke survivors. There was little evidence to support case management or the use of integrated care pathways for people with ABI. We found evidence that a quality monitoring intervention can lead to improvements in process outcomes in acute and rehabilitation settings. We were unable to find any studies meeting our inclusion criteria regarding fee-for-service care or engaging consumers in the governance of the health care organisation. Conclusions The review found evidence to support integrated care, early supported discharge and quality monitoring interventions however, this evidence was based on studies conducted with people following stroke and may not be appropriate for all people with an ABI

INCOG 2.0 Guidelines for Cognitive Rehabilitation Following Traumatic Brain Injury, Part III: Executive Functions

Introduction: Moderate-to-severe traumatic brain injury (MS-TBI) causes debilitating and enduring impairments of executive functioning and self-awareness, which clinicians often find challenging to address. Here, we provide an update to the INCOG 2014 guidelines for the clinical management of these impairments. Methods: An expert panel of clinicians/researchers (known as INCOG) reviewed evidence published from 2014 and developed updated recommendations for the management of executive functioning and self-awareness post-MS-TBI, as well as a decision-making algorithm, and an audit tool for review of clinical practice. Results: A total of 8 recommendations are provided regarding executive functioning and self-awareness. Since INCOG 2014, 4 new recommendations were made and 4 were modified and updated from previous recommendations. Six recommendations are based on level A evidence, and 2 are based on level C. Recommendations retained from the previous guidelines and updated, where new evidence was available, focus on enhancement of self-awareness (eg, feedback to increase self-monitoring; training with video-feedback), meta-cognitive strategy instruction (eg, goal management training), enhancement of reasoning skills, and group-based treatments. New recommendations addressing music therapy, virtual therapy, telerehabilitation-delivered metacognitive strategies, and caution regarding other group-based telerehabilitation (due to a lack of evidence) have been made. Conclusions: Effective management of impairments in executive functioning can increase the success and well-being of individuals with MS-TBI in their day-to-day lives. These guidelines provide management recommendations based on the latest evidence, with support for their implementation, and encourage researchers to explore and validate additional factors such as predictors of treatment response

INCOG 2.0 Guidelines for Cognitive Rehabilitation Following Traumatic Brain Injury: What’s Changed From 2014 to Now?

IT IS CRITICAL TO KEEP clinical practice guidelines (CPGs) up to date through integration of the latest evidence. Therefore, it is with great excitement that the INCOG team presents the INCOG 2.0 Guidelines for Cognitive Rehabilitation Following Traumatic Brain Injury (TBI). In this brief introduction, we provide an overview of changes in the evidence from 2014; share insights into the current state and challenges implementing cognitive rehabilitation; and provide an overview of INCOG 2022

INCOG 2.0 Guidelines for Cognitive Rehabilitation Following Traumatic Brain Injury, Part V: Memory

Introduction: Memory impairments affecting encoding, acquisition, and retrieval of information after moderate-to-severe traumatic brain injury (TBI) have debilitating and enduring functional consequences. The interventional research reviewed primarily focused on mild to severe memory impairments in episodic and prospective memory. As memory is a common focus of cognitive rehabilitation, clinicians should understand and use the latest evidence. Therefore, the INCOG (“International Cognitive”) 2014 clinical practice guidelines were updated. Methods: An expert panel of clinicians/researchers reviewed evidence published since 2014 and developed updated recommendations for intervention for memory impairments post-TBI, a decision-making algorithm, and an audit tool for review of clinical practice. Results: The interventional research approaches for episodic and prospective memory from 2014 are synthesized into 8 recommendations (6 updated and 2 new). Six recommendations are based on level A evidence and 2 on level B. In summary, they include the efficacy of choosing individual or multiple internal compensatory strategies, which can be delivered in a structured or individualized program. Of the external compensatory strategies, which should be the primary strategy for severe memory impairment, electronic reminder systems such as smartphone technology are preferred, with technological advances increasing their viability over traditional systems. Furthermore, microprompting personal digital assistant technology is recommended to cue completion of complex tasks. Memory strategies should be taught using instruction that considers the individual\u27s functional and contextual needs while constraining errors. Memory rehabilitation programs can be delivered in an individualized or mixed format using group instruction. Computer cognitive training should be conducted with therapist guidance. Limited evidence exists to suggest that acetylcholinesterase inhibitors improve memory, so trials should include measures to assess impact. The use of transcranial direct current stimulation (tDCS) is not recommended for memory rehabilitation. Conclusion: These recommendations for memory rehabilitation post-TBI reflect the current evidence and highlight the limitations of group instruction with heterogeneous populations of TBI. Further research is needed on the role of medications and tDCS to enhance memory

The Future of INCOG (Is Now)

IT HAS BEEN 8 years since the first iteration of the INCOG clinical practice guidelines (CPGs) were published. Much has happened since 2014, and a considerable body of evidence has been published in the various domains of cognitive rehabilitation research represented in this special issue. Over this time, significant developments in the science of identifying, appraising, and distilling research evidence into practically applicable CPGs have emerged, as well as implementation efforts to ensure meaningful change in care delivery

Division of Physical Medicine and Rehabilitation (Krassioukov)

Objective: To review systematically the evidence for the management of orthostatic hypotension (OH) in patients with spinal cord injuries (SCIs). Data Sources: A key word literature search was conducted of original and review articles as well as practice guidelines using Medline, CINAHL, EMBASE, and PsycInfo, and manual searches of retrieved articles from 1950 to July 2008, to identify literature evaluating the effectiveness of currently used treatments for OH. Study Selection: Included randomized controlled trials (RCTs), prospective cohort studies, case-control studies, prepost studies, and case reports that assessed pharmacologic and nonpharmacologic intervention for the management of OH in patients with SCI. Data Extraction: Two independent reviewers evaluated the quality of each study, using the Physiotherapy Evidence Database score for RCTs and the Downs and Black scale for all other studies. Study results were tabulated and levels of evidence assigned. Data Synthesis: A total of 8 pharmacologic and 21 nonpharmacologic studies were identified that met the criteria. Of these 26 studies (some include both pharmacologic and nonpharmacologic interventions), only 1 pharmacologic RCT was identified (low-quality RCT producing level 2 evidence), in which midodrine was found to be effective in the management of OH after SCI. Functional electrical stimulation was one of the only nonpharmacologic interventions with some evidence (level 2) to support its utility. Conclusions: Although a wide array of physical and pharmacologic measures are recommended for the management of OH in the general population, very few have been evaluated for use in SCI. Further research needs to quantify the efficacy of treatment for OH in subjects with SCI, especially of the many other pharmacologic interventions that have been shown to be effective in non-SCI conditions. Key Words: Hypotension; orthostatic; Rehabilitation; Review [publication type]; Spinal cord injuries. © by the American Congress of Rehabilitation Medicine T HE DEFINITION OF orthostatic hypotension is typically accepted as a decrease in systolic blood pressure of 20mmHg or more, or a reduction in diastolic blood pressure of 10mmHg or more, on changing body position from a supine position to an upright posture, regardless of the presence of symptoms. 1 Numerous studies have documented the presence of OH after SCI. 2-5 OH is more common in tetraplegia than paraplegia, with prevalence rates as high as 82% for tetraplegia versus 50% for those with paraplegia immediately post-SCI. 5 This condition not only is evident in the acute period postinjury but also has persisted in a significant number of persons for many years. 6-8 Standard mobilization during physiotherapy (eg, sitting or standing) is reported to induce blood pressure decreases that are diagnostic of OH in 74% of patients with SCI, and which are accompanied by OH symptoms (like lightheadedness or dizziness) (appendix 1) in 59% of patients with SCI. 5 This in turn may have a negative impact on the ability of subjects with SCI to participate in rehabilitation. Current management approaches for the treatment of OH consist of pharmacologic and nonpharmacologic interventions. The low level of efferent sympathetic nervous activity and the loss of reflex vasoconstriction after SCI are among the major causes of OH. The decrease in arterial blood pressure after a change to an upright position in subjects with SCI appears to be related to excessive pooling of blood in the abdominal viscera and lower extremities. 10 A subsequent reduction in cardiac output and arterial pressure may lead to tachycardia. However, this reflex tachycardia is often insufficient to compensate for the lowered output and pressure. Consequently, the pooling of blood in the lower extremities and the decrease in blood pressure may resul
