Background and Purpose: The Chedoke-McMaster Stroke Assessment measures the physical impairments and disabilities that impact on the lives of individuals with stroke. This measure has three overall purposes: 1) to stage motor recovery to classify individuals in terms of clinical characteristics, 2) to predict rehabilitation outcomes, and 3) to measure clinically important change in physical function. This study was carried out to evaluate the ability of this measure to yield reliable and valid results.
Purpose: The purpose of this study was to undertake a systematic assessment of the need for research-based information by decision-makers working in community-based organizations. It is part of a more comprehensive knowledge transfer and exchange strategy that seeks to understand both the content required and the format/methods by which such information should be presented.
Methods:This was a cross-sectional telephone survey. Questions covered current practices, research use, and demographic information, as well as preferences for receiving research information. Three types of organizations participated: Children's Treatment Centres of Ontario (CTCs); Ontario Community Care Access Centres (CCACs); and District Health Councils (DHCs). The analysis used descriptive statistics and analyses of variance (ANOVA) to describe and explore variations across organizations.
Results:The participation rate was 70%. The highest perception of barriers to the use of research information was reported by the CCAC respondents, followed by CTCs and DHCs. The CTCs and DHCs reported greater use of research evidence in planning decisions as compared to the CCACs. Four sources of information transfer were consistently identified. These were websites, health-related research journals, electronic mail, and conferences and workshops. Preferred formats for receiving information were executive summaries, abstracts, and original articles.
Conclusion:There were a number of similarities across organization type with respect to perceived barriers to research transfer, as well as the types of activities the organizations engaged in to promote research use in decision-making. These findings support the importance of developing interactive, collaborative knowledge transfer strategies, as well as the need to foster relationships with health care decision-makers, practitioners and policymakers.
Forty-four patients with hemiplegia following stroke and 10 nondisabled subjects were studied to examine the contributions inadequate motor unit recruitment and co-contraction attributable to impaired antagonist inhibition play in the movement disorder of the hemiplegic arm. Electromyographic data were recorded from agonist and antagonist muscles while subjects attempted six specified tasks. Data from subjects who could complete the tasks were compared with those who could not complete the tasks. Differences between the two groups were found in the electromyographic data obtained from the agonist muscles. Electromyographic values were consistently and significantly lower in patients who were unable to complete the tasks than in patients who were able to complete the tasks. In the antagonist muscles, a significant difference was noted only once; in this case, the EMG values were again lower in the group of patients who were unable to complete the task. Inadequate recruitment of agonists, not increased activity in the antagonists, was a consistent finding in patients who were unable to carry out the movement tasks. This study theoretically supports aiming treatment efforts at improving motoneuron recruitment rather than reducing activity in antagonists while retraining arm function.
Although there are a number of advantages to using videotapes to train test users and to assess scoring reliability, this method does not evaluate participants' ability to administer the measure. Further work is needed to determine whether reliability is maintained in a clinical situation in which it is necessary to both administer and score the GMFM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
