Time to Rethink Long-Term Rehabilitation Management of Stroke Patients

Abstract Background: It has long been assumed that stroke patients plateau in their recovery within 3 to 6 months of their stroke, and evidence for rehabilitation during the chronic stage is limited. As a consequence, rehabilitation resources for the management of chronic stroke are minimal. Objective: The primary objective was to identify randomized controlled trials (RCTs) across the continuum of stroke rehabilitation for interventions initiated 6 months or more following the onset of stroke. The secondary objective was to determine whether treatments provided post 6 months are effective in improving outcomes among stroke survivors. Methods: Multiple databases were used to identify all RCTs published from 1970 to June 2012 in the English language where the stroke rehabilitation interventions were initiated more than 6 months after the onset of the stroke. Data abstraction was performed using a standardized data abstraction form that included general citation information, study participant characteristics, methodology, outcomes assessed, and overall findings. Results: The results of our analysis revealed 339 RCTs. The mean number of subjects per study was 73. Two hundred fifty-six RCTs were related to motor recovery, 39 to cognitive function, and only 19 to psychosocial issues and community reintegration. The majority of the RCTs demonstrated a significant positive benefit. Conclusions: There is a robust evidence-base for stroke rehabilitation interventions in chronic stroke. This research synthesis reveals a paradox, whereby an impressive evidencebase contrasts with the limited optimism and resources available for rehabilitation in chronic stroke.

Canadian stroke best practice recommendations: Stroke rehabilitation practice guidelines, update 2015:

Stroke rehabilitation is a progressive, dynamic, goal-orientated process aimed at enabling a person with impairment to reach their optimal physical, cognitive, emotional, communicative, social and/or functional activity level. After a stroke, patients often continue to require rehabilitation for persistent deficits related to spasticity, upper and lower extremity dysfunction, shoulder and central pain, mobility/gait, dysphagia, vision, and communication. Each year in Canada 62,000 people experience a stroke. Among stroke survivors, over 6500 individuals access in-patient stroke rehabilitation and stay a median of 30 days (inter-quartile range 19 to 45 days). The 2015 update of the Canadian Stroke Best Practice Recommendations: Stroke Rehabilitation Practice Guidelines is a comprehensive summary of current evidence-based recommendations for all members of multidisciplinary teams working in a range of settings, who provide care to patients following stroke. These recommendations have been developed to address both the organization of stroke rehabilitation within a system of care (i.e., Initial Rehabilitation Assessment; Stroke Rehabilitation Units; Stroke Rehabilitation Teams; Delivery; Outpatient and Community-Based Rehabilitation), and specific interventions and management in stroke recovery and direct clinical care (i.e., Upper Extremity Dysfunction; Lower Extremity Dysfunction; Dysphagia and Malnutrition; Visual-Perceptual Deficits; Central Pain; Communication; Life Roles). In addition, stroke happens at any age, and therefore a new section has been added to the 2015 update to highlight components of stroke rehabilitation for children who have experienced a stroke, either prenatally, as a newborn, or during childhood. All recommendations have been assigned a level of evidence which reflects the strength and quality of current research evidence available to support the recommendation. The updated Rehabilitation Clinical Practice Guidelines feature several additions that reflect new research areas and stronger evidence for already existing recommendations. It is anticipated that these guidelines will provide direction and standardization for patients, families/caregiver(s), and clinicians within Canada and internationally.

Mortality among older adults after a traumatic brain injury: A meta-analysis

Primary objective: To examine mortality rates among older adults (≥60 years) post-traumatic brain injury (TBI). Research design: Systematic review and meta-analysis. Methods and procedures: Using multiple databases, a literature search was conducted for articles on mortality after TBI published up to July 2011. Information on patient characteristics (age, Glasgow Coma Scale (GCS), injury aetiology, etc.), mortality rates, time to death and study design was extracted and pooled. Main outcomes and results: Twenty-four studies had an overall mortality rate of 38.3% (CI 27.1–50.9%). The odds of mortality for those over 75 years compared to those of 65–74 years was 1.734 (CI = 1.311–2.292; p < 0.0001). Pooled mortality rates for mild (GCS 13–15), moderate (GCS 9–12) and severe (GCS 3–8) head injuries were 12.3% (CI = 6.1–23.3%), 34.3% (CI = 19.5–53.0%) and 65.3% (CI = 53.1–75.9), respectively. Odds ratios comparing severe to mild and moderate to mild head injuries were 12.69 (CI = 5.29–30.45; p < 0.0001) and 5.31 (CI = 3.41-8.29; p < 0.0001), respectively. There was no significant difference in the odds of death between severe and moderate injuries (p = 0.116). Conclusions: These mortality rates associated with moderate and severe injuries may be attributed to complications, chronic disease prevalence, conservative management techniques or the consequences of biological ageing.

Systematic review and meta-analysis of constraint-induced movement therapy in the hemiparetic upper extremity more than six months post stroke.

Abstract Objective: To conduct a systematic review and meta-analysis of the available evidence on the effectiveness of constraint-induced movement therapy (CIMT) in the hemiparetic upper extremity (UE) among individuals who were more than 6 months post stroke. Methods: A literature search of multiple databases (PubMed, CINAHL, and EMBASE) was conducted to identify articles published in the English language up to and including July 2012. Studies were included for review if (1) ≥50% of the sample had sustained a stroke, (2) the research design was a randomized controlled trial (RCT), (3) the mean time since stroke was ≥6 months for both the treated and control groups, (4) the treatment group received CIMT, (5) the control group received a form of traditional rehabilitation, and (6) functional improvement was assessed both pre and posttreatment. Methodological quality was assessed using the PEDro tool with a score out of 10. Results: Sixteen RCTs (PEDro scores 4–8) met inclusion criteria and included a pooled sample size of 572 individuals with a mean age of 58.2 years (range, 30–87). The meta-analysis revealed a significant treatment effect on the amount of use and quality of movements subscales of the Motor Activity Log (P < .001, for both), Fugl-Meyer Assessment (P = .014), and Action Research Arm Test (P = .001); however, there was no significant treatment effect demonstrated by the Wolf Motor Function Test (P = .120) or FIM (P = .070). Conclusions: CIMT to improve UE function is an appropriate and beneficial therapy for individuals who have sustained a stroke more than 6 months previously.

Incog Recommendations for Management of Cognition Following Traumatic Brain Injury, Part V: Memory

Introduction:Traumatic brain injury results in complex cognitive sequelae. Impairments in memory are among the most common sequelae resulting in significant functional problems. An international team of researchers and clinicians (known as INCOG) was formed to develop recommendations for the management of impairments in memory. Methods:The experts met to select appropriate recommendations and then reviewed available literature to ensure recommendations were current. Decision algorithms incorporating the recommendations based on inclusion and exclusion criteria of published trials were developed. The team then prioritized recommendations for implementation and developed audit criteria to evaluate adherence to the best practice recommendations. Results:The recommendations for rehabilitation of memory impairments support the integration of internal and external compensatory strategies implemented using appropriate instructional techniques that consider functional relevance and important patient characteristics. Restorative strategies have regained significant popularity, given broader access to computer technology; however, evidence for efficacy of these techniques remains weak and the choice in using these should be guided by special considerations. Conclusion:There is good evidence for the integration of internal and external compensatory memory strategies that are implemented using instructional procedures for rehabilitation for memory impairments. The evidence for the efficacy of restorative strategies currently remains weak.

INCOG Recommendations for management of cognition following traumatic brain injury. Part II: Attention and information processing speed

Introduction:Traumatic brain injury, due to its diffuse nature and high frequency of injury to frontotemporal and midbrain reticular activating systems, may cause disruption in many aspects of attention: arousal, selective attention, speed of information processing, and strategic control of attention, including sustained attention, shifting and dividing of attention, and working memory. An international team of researchers and clinicians (known as INCOG) convened to develop recommendations for the management of attentional problems. Methods:The experts selected recommendations from published guidelines and then reviewed literature to ensure that recommendations were current. Decision algorithms incorporating the recommendations based on inclusion and exclusion criteria of published trials were developed. The team then prioritized recommendations for implementation and developed audit criteria to evaluate adherence to these best practices. Results:The recommendations and discussion highlight that metacognitive strategy training focused on functional everyday activities is appropriate. Appropriate use of dual task training, environmental modifications, and cognitive behavioral therapy is also discussed. There is insufficient evidence to support mindfulness meditation and practice on de-contextualized computer-based tasks for attention. Administration of the medication methylphenidate should be considered to improve information-processing speed. Conclusion:The INCOG recommendations for rehabilitation of attention provide up-to-date guidance for clinicians treating people with traumatic brain injury.

Bladder cancer in individuals with spinal cord injuries

Study design:Prospective scoping review.Objectives:To conduct a scoping review of all the literature related to bladder cancer in individuals with spinal cord injuries (SCI).Methods:Literature search of the databases Pubmed, CINAHL, ProQuest, PsychINFO and Scopus up to and including August 2012. Articles related to bladder cancer among SCI patients were identified, and data pertaining to epidemiology, risk factors, screening, prevention and management was reviewed and summarized.Results:An association between bladder cancer and SCI was first reported in the 1960s, with some case reports suggesting an alarmingly high rate among SCI patients. More recent epidemiological studies have reported this risk to be substantially lower. However, bladder cancer in SCI patients tends to present at an earlier age and at a more advanced pathological stage than bladder cancer in the general population. Presenting symptoms may be atypical, and early recognition is important to improve prognosis with surgical resection. Several risk factors have been identified, including indwelling catheters, urinary tract infections and bladder calculi. Screening of SCI patients for bladder cancer is routinely recommended in many SCI management guidelines and by expert consensus; however, evidence for screening tools and protocols is lacking.Conclusion:Bladder cancer is a rare, and potentially lethal occurrence in SCI patients. Physicians need to have a high index of suspicion for bladder cancer, particularly among SCI patients managed with long-term indwelling catheters.

Rethinking the continuum of stroke rehabilitation.

Suffering a stroke can be a devastating and life-changing event. Although there is a large evidence base for stroke rehabilitation in the acute and subacute stages, it has been long accepted that patients with stroke reach a plateau in their rehabilitation recovery relatively early. We have recently published the results of a systematic review designed to identify all randomized controlled trials (RCTs) where a rehabilitation intervention was initiated more than 6 months after the onset of the stroke. Of the trials identified, 339 RCTs met inclusion criteria, demonstrating an evidence base for stroke rehabilitation in the chronic phase as well. This seems at odds with the assumption that further recovery is unlikely and the subsequent lack of resources devoted to chronic stroke rehabilitation and management.

Functional Electrical Stimulation for Improving Gait in Persons With Chronic Stroke

Abstract Background: The long-term management of stroke is an area of increasing clinical interest, and it is important to identify therapeutic interventions that are effective in the chronic phase post stroke. Objective: To conduct a systematic review on the effectiveness of functional electrical stimulation (FES) in improving lower extremity function in chronic stroke. Methods: Multiple databases (PubMed, CINAHL, EMBASE, and Scopus) were searched for relevant articles. Studies were included for review if (1) ≥50% of the study population has sustained a stroke, (2) the study design was a randomized controlled trial (RCT), (3) the mean time since stroke was ≥6 months, (4) FES or neuromuscular electrical stimulation (NMES) was compared to other interventions or a control group, and (5) functional lower extremity outcomes were assessed. Methodological quality was assessed using the PEDro tool. A standardized mean difference (SMD ± SE and 95% confidence interval [CI]) was calculated for the 6-minute walk test (6MWT). Pooled analysis was conducted for treatment effect of FES on the 6MWT distance using a fixed effects model. Results: Seven RCTs (PEDro scores 5–7) including a pooled sample size of 231 participants met inclusion criteria. Pooled analysis revealed a small but significant treatment effect of FES (0.379 ± 0.152; 95% CI, 0.081 to 0.677; P = .013) on 6MWT distance. Conclusion: FES may be an effective intervention in the chronic phase post stroke. However, its therapeutic value in improving lower extremity function and superiority over other gait training approaches remains unclear.

INCOG recommendations for management of cognition following traumatic brain injury, part I: posttraumatic amnesia/delirium.

Introduction:After traumatic brain injury (TBI) and emergence from coma, the majority of people experience posttraumatic amnesia (PTA), characterized by confusion, disorientation, retrograde and anterograde amnesia, poor attention, and sometimes agitation and delusions. An international team of researchers and clinicians developed recommendations for assessment and management of PTA. Methods:The experts met to select recommendations, then reviewed literature to ensure they were current. The team then prioritized recommendations for implementation and developed audit criteria to evaluate the adherence to the best practice recommendations. Results:Evidence in support of assessment and management strategies during PTA is weak. It is recommended that duration of PTA be assessed prospectively using a validated tool. Consideration should also be given to use of a delirium assessment tool. No cognitive or pharmacological treatments are known to reduce PTA duration. Recommendations for environmental manipulations to reduce agitation during PTA are made. Minimizing use of neuroleptic medication is supported by animal research and 1 retrospective study. Conclusions:The duration of PTA is an important predictor of late outcome after TBI and should be monitored prospectively with a standardized tool. Neuroleptic medication should be avoided. There is a significant need for controlled studies evaluating the impact of therapy during PTA.
