Initial experience of a digital training resource for modified Rankin scale assessment in clinical trials.
BACKGROUND AND PURPOSE The modified Rankin Scale (mRS) is the preferred measure of disability in cerebrovascular clinical trials, but its value is restricted by interobserver variability. Poor reliability reduces the statistical power of clinical trials and leads to underestimation of effect size. Strategies to improve mRS grading are required. Video training has previously improved application...

متن کاملImproving modified Rankin Scale assessment with a simplified questionnaire.
BACKGROUND AND PURPOSE The modified Rankin Scale (mRS) is a popular primary stroke outcome measure, but its usefulness is limited by suboptimal reliability (inter-rater agreement). METHODS We developed and tested the reliability of a simplified mRS questionnaire (smRSq) in 50 patients after stroke seen in outpatient clinics. Randomly chosen paired raters administered the smRSq within 20 minut...
متن کاملAnalysis of the modified rankin scale in randomised controlled trials in acute stroke: a systematic review
Background Historically, trials in acute stroke have largely been unable to show benefit of new interventions. Trials have previously favoured dichotomous analysis of outcome measures employing an ordinal scale, such as the Modified Rankin Scale (mRS). In 2007, the OAST Collaboration showed that preserving the ordinal nature of these scales increased statistical power, recommending the use of o...
متن کاملOutcomes validity and reliability of the modified Rankin scale: implications for stroke clinical trials: a literature review and synthesis.
BACKGROUND AND PURPOSE The modified Rankin scale (mRS), a clinician-reported measure of global disability, is widely applied for evaluating stroke patient outcomes and as an end point in randomized clinical trials. Extensive evidence on the validity of the mRS exists across a large but fragmented literature. As new treatments for acute ischemic stroke are submitted for agency approval, an appre...
