Impact of early vs delayed admission to rehabilitation on functional outcomes in persons with stroke.

OBJECTIVE: Delayed admission to rehabilitation may result in poorer outcomes by reducing exposure to therapeutic interventions at a time when the brain is primed for neurological recovery. The present study examined the effects of early vs delayed admission on functional outcome and length of stay in patients admitted to a rehabilitation unit for first-ever unilateral stroke. DESIGN: Retrospective chart review. METHODS: Differences in length of rehabilitation stay and functional outcome variables among 435 patients, grouped by interval from stroke event to rehabilitation admission (=30 days vs 31-150 days and 5 additional subgroups) were examined using a multivariate technique. RESULTS: Admission and discharge FIM scores, FIM change and FIM efficiency were significantly higher among early admission patients (p<0.01), while length of stay was significantly longer among delayed admission patients (p<0.01). A significant association was identified between age and admission (p<0.01) and discharge FIM (p<0.01) scores as well as FIM change scores (p=0.017). Subgroup analyses revealed significant differences in FIM scores, FIM change and length of stay between groups of patients admitted 0-15 and 16-30 days (p<0.01) and between patients admitted 16-30 days and 31-60 days post-stroke (p<0.01). No significant differences were noted between patients admitted from 31-60 and 61-90 or 61-90 and 91-150 days. CONCLUSION: Patients admitted to stroke rehabilitation within 30 days of first-ever, unilateral stroke experienced greater functional gains and shorter lengths of stay than those whose admission to rehabilitation was delayed beyond 30 days.

Evidence-based practice and setting basic standards for stroke rehabilitation in Canada.

It is a concern that the consistency of care in stroke rehabilitation appears to vary significantly among practice settings within Canada. Based upon an evidence-based review of stroke rehabilitation, a group of physiatrists from across Canada agreed to some basic standards for stroke rehabilitation. The following standards were deemed to be critical to providing effective stroke rehabilitation care: early assessment and quick access to specialized interdisciplinary rehabilitation, appropriate intensity of therapies, availability of outpatient therapy, appropriate community supports, and careful attention to secondary prevention of stroke. Providing stroke rehabilitation care consistently within these standards remains a challenge, particularly given the potential initial costs, despite significant improvements in patient outcomes and quality of life. Nevertheless, these standards should be the expectation of stroke patients, essentially forming a stroke rehabilitation "bill of rights."

Dysphagia after stroke: incidence, diagnosis, and pulmonary complications.

OBJECTIVE: To determine the incidence of dysphagia and associated pulmonary compromise in stroke patients through a systematic review of the published literature. METHODS: Databases were searched (1966 through May 2005) using terms "cerebrovascular disorders," "deglutition disorders," and limited to "humans" for original articles addressing the frequency of dysphagia or pneumonia. Data sources included Medline, Embase, Pascal, relevant Internet addresses, and extensive hand searching of bibliographies of identified articles. Selected articles were reviewed for quality, diagnostic methods, and patient characteristics. Comparisons were made of reported dysphagia and pneumonia frequencies. The relative risks (RRs) of developing pneumonia were calculated in patients with dysphagia and confirmed aspiration. RESULTS: Of the 277 sources identified, 104 were original, peer-reviewed articles that focused on adult stroke patients with dysphagia. Of these, 24 articles met inclusion criteria and were evaluated. The reported incidence of dysphagia was lowest using cursory screening techniques (37% to 45%), higher using clinical testing (51% to 55%), and highest using instrumental testing (64% to 78%). Dysphagia tends to be lower after hemispheric stroke and remains prominent in the rehabilitation brain stem stroke. There is increased risk for pneumonia in patients with dysphagia (RR, 3.17; 95% CI, 2.07, 4.87) and an even greater risk in patients with aspiration (RR, 11.56; 95% CI, 3.36, 39.77). CONCLUSIONS: The high incidence for dysphagia and pneumonia is a consistent finding with stroke patients. The pneumonia risk is greatest in stroke patients with aspiration. These findings will be valuable in the design of future dysphagia research.

A comparison of the Barthel Index and the Functional Independence Measure as outcome measures in stroke rehabilitation: patterns of disability scale usage in clinical trials.

In order to compare the frequency and patterns of use of the Barthel Index (BI) and Functional Independence Measure (FIM) in stroke rehabilitation trials, all randomized controlled trials (RCTs) of stroke rehabilitation published between 1968 and 2002 were identified and reviewed to determine the frequency with which the BI and FIM measures were used relative to other measures of disability. The date and location of each study citing either the FIM or the BI were also recorded. Studies were assigned ratings of methodological quality based on the physiotherapy evidence database (PEDro) scoring system. Comparisons of the age, frequency and continents of origin and methodological quality of the studies were explored. Results indicate that the BI and FIM were the most common measures of disability used in RCTs examining stroke rehabilitation. However, the BI was used more often than the FIM (n=86, P<0.001) and was cited in trials of superior quality (P=0.005). Studies from North America were more likely to use the FIM compared with European studies (n=24, P<0.001). Publications citing the BI were significantly more recent when originating in Europe as opposed to North America (P=0.023). These results provide insight into current patterns of scale use in stroke rehabilitation research.

Recovery from stroke: differences between subtypes.

The objective of this study was to compare the differences in patterns of recovery and incidence of medical complications in hemorrhagic and ischemic stroke patients admitted for rehabilitation, using a retrospective case series design. It was set in three tertiary care facilities in London, Ontario, Canada. Eight-hundred-and-nineteen consecutive patients, admitted from 1997 to 2001 for rehabilitation following cerebrovascular event, were reviewed. The main outcome measures were: age, length of hospital stay, time to admission, medical complications, ambulation status and functional independence measure scores on both admission and discharge. The results showed that 110 patients had strokes that were hemorrhagic, while 709 were ischemic. The hemorrhagic stroke patients were younger (66 vs. 70 years, P=0.001) and were admitted later post stroke onset (30 vs. 18 days, P<0.0001). They had a higher incidence of pneumonia (6.4 vs. 2.7%, P=0.04), pulmonary emboli (3.6 vs. 0.07%, P=0.006) and wheelchair ambulation on admission (53 vs. 41%, P=0.026). There was no significant difference in incidence of seizures or wheelchair ambulation on discharge, length of rehabilitation stay or Functional Independence Measure scores on both admission and discharge. In conclusion, hemorrhagic stroke patients took longer than ischemic stroke patients to enter into rehabilitation, and were more inclined to experience ambulatory impairments and develop medical complications.

Treatment of whiplash-associated disorders--part I: Non-invasive interventions.

BACKGROUND: A whiplash-associated disorder (WAD) is an injury due to an acceleration-deceleration mechanism at the neck. WAD represents a very common and costly condition, both economically and socially. In 1995, the Quebec Task Force published a report that contained evidence-based recommendations regarding the treatment of WAD based on studies completed before 1993 and consensus-based recommendations. OBJECTIVE: The objective of the present article--the first installment of a two-part series on interventions for WAD--is to provide a systematic review of the literature published between January 1993 and July 2003 on noninvasive interventions for WAD using meta-analytical techniques. METHODS OF THE REVIEW: Three medical literature databases were searched for identification of all studies on the treatment of WAD. Randomized controlled trials (RCTs) and epidemiological studies were categorized by treatment modality and analyzed by outcome measure. The methodological quality of the RCTs was assessed. When possible, pooled analyses of the RCTs were completed for meta-analyses of the data. The results of all the studies were compiled and systematically reviewed. RESULTS: Studies were categorized as exercise alone, multimodal intervention with exercise, mobilization, strength training, pulsed magnetic field treatment and chiropractic manipulation. A total of eight RCTs and 10 non-RCTs were evaluated. The mean score of methodological quality of the RCTs was five out of 10. Pooled analyses were completed across all treatment modalities and outcome measures. The outcomes of each study were summarized in tables. CONCLUSIONS: There exists consistent evidence (published in two RCTs) in support of mobilization as an effective noninvasive intervention for acute WAD. Two RCTs also reported consistent evidence that exercise alone does not improve range of motion in patients with acute WAD. One RCT reported improvements in pain and range of motion in patients with WAD of undefined duration who underwent pulsed electromagnetic field treatment. Conflicting evidence in two RCTs exists regarding the effectiveness of multimodal intervention with exercise. Limited evidence, in the form of three non-RCTs, exists in support of chiropractic manipulation. Future research should be directed toward clarifying the role of exercise and manipulation in the treatment of WAD, and supporting or refuting the benefit of pulsed electromagnetic field treatment. Mobilization is recommended for the treatment of pain and compromised cervical range of motion in the acute WAD patient.

Treatment of whiplash-associated disorders--part II: Medical and surgical interventions.

BACKGROUND: Whiplash-associated disorder (WAD) is a term used to describe injury due to an acceleration-deceleration mechanism at the neck. In 1995, the Quebec Task Force published a report that contained evidence-based recommendations regarding the treatment of WAD based on studies completed before 1993 and consensus-based recommendations. OBJECTIVE: The objective of the present article--the second installment of a two part review on WAD--is to provide a systematic review of the literature published between January 1993 and July 2003 on medical and surgical interventions for WAD using meta-analytical techniques. METHODS OF THE REVIEW: Three medical literature databases were searched for identification of all clinical trials on the treatment of WAD. Randomized controlled trials (RCTs) and epidemiological studies were categorized by treatment modality and analyzed by outcome measures. The methodological quality of the RCTs was assessed. When possible, pooled analyses of the RCTs were completed for meta-analyses of the data. The results of all the studies were compiled and systematically reviewed. RESULTS: The studies were categorized as medical or surgical interventions. A total of five RCTs and six non-RCTs were evaluated. The mean methodological quality of the RCTs was 7.3 among studies on medical interventions and 7.5 for studies on surgical intervention. Pooled analyses were completed across all treatment modalities and outcome measures. The outcomes of each study were summarized in tables. CONCLUSIONS: While several quality RCTs and epidemiological studies have been published since 1993 on medical and surgical interventions, the cumulative evidence is lacking. Moderate evidence exists in support of radiofrequency neurotomy. Evidence for steroid injections, botulinum treatments, carpal tunnel decompression and cervical discectomy is conflicting or unclear. Future research is required to clarify the utility of radiofrequency neurotomy and pulsed electromagnetic field treatment for WAD.
