TLDR
This new, stroke-specific outcome measure is reliable, valid, and sensitive to change and more studies are required to evaluate the SIS in larger and more heterogeneous populations and to evaluates the feasibility and validity of proxy responses for the most severely impaired patients.Abstract:
Background and Purpose—To be useful for clinical research, an outcome measure must be feasible to administer and have sound psychometric attributes, including reliability, validity, and sensitivity to change. This study characterizes the psychometric properties of the Stroke Impact Scale (SIS) Version 2.0. Methods—Version 2.0 of the SIS is a self-report measure that includes 64 items and assesses 8 domains (strength, hand function, ADL/IADL, mobility, communication, emotion, memory and thinking, and participation). Subjects with mild and moderate strokes completed the SIS at 1 month (n=91), at 3 months (n=80), and at 6 months after stroke (n=69). Twenty-five subjects had a replicate administration of the SIS 1 week after the 3-month or 6-month test. We evaluated internal consistency and test-retest reliability. The validity of the SIS domains was examined by comparing the SIS to existing stroke measures and by comparing differences in SIS scores across Rankin scale levels. The mixed model procedure was us...read more

TL;DR: The Extremity Constraint Induced Therapy Evaluation (EXCITE) trial as mentioned in this paper showed that a 2-week program of constraint-induced movement therapy (CIMT) for patients more than 1 year after stroke who maintain some hand and wrist movement can improve upper extremity function that persists for at least 1 year.
Effect of Constraint-Induced Movement Therapy on Upper Extremity Function 3 to 9 Months After Stroke
TL;DR: The Extremity Constraint Induced Therapy Evaluation (EXCITE) trial as discussed by the authors was designed to compare the effects of a 2-week multisite program of CIMT vs usual andcustomary care.

Outcomes validity and reliability of the modified Rankin scale: implications for stroke clinical trials: a literature review and synthesis.
TL;DR: The reported data support the view that the modified Rankin scale is a valuable instrument for assessing the impact of new stroke treatments, and patient comorbidities and socioeconomic factors should be considered in properly applying and interpreting the mRS.

TL;DR: This document serves to standardize reporting terminology and includes pretreatment assessment, neurologic evaluation with the NIH Stroke Scale score, imaging evaluation, occlusion sites, perfusion grades, follow-up imaging studies, and neurologic assessments, and suggestions for uniform reporting standards for such trials.

Rasch analysis of a new stroke-specific outcome scale: the Stroke Impact Scale.
TL;DR: The domains are unidimensional, the items have an excellent range of difficulty, and the domain scores differentiated patients into multiple strata.

“Mini-mental state”: A practical method for grading the cognitive state of patients for the clinician

TL;DR: A simplified, scored form of the cognitive mental status examination, the “Mini-Mental State” (MMS) which includes eleven questions, requires only 5-10 min to administer, and is therefore practical to use serially and routinely.

Coefficient alpha and the internal structure of tests.
TL;DR: In this paper, a general formula (α) of which a special case is the Kuder-Richardson coefficient of equivalence is shown to be the mean of all split-half coefficients resulting from different splittings of a test, therefore an estimate of the correlation between two random samples of items from a universe of items like those in the test.
