Area of Science:

Neurology
Medical Informatics

Context:

Existing stroke scales lack objective quantification of stroke severity.
The Japan Stroke Society developed a novel, quantifiable scale for acute stroke assessment.

Purpose:

To introduce the Japan Stroke Scale (JSS) as a quantifiable tool for assessing stroke severity.
To present the development and application of the JSS and its variants (Motor Function, Higher Cortical Function).

Summary:

The Japan Stroke Scale (JSS) was developed using conjoint analysis to objectively quantify stroke severity in the acute phase.
The JSS, along with its Motor Function and Higher Cortical Function variants, are parametric scales used for monitoring patients and in clinical studies.
The JSS has been utilized in clinical trials, demonstrating statistical power and potential for treatment efficacy assessment.

Impact:

The JSS provides a reliable method for monitoring neurological damage in acute and chronic stroke phases.
It aids in estimating stroke symptom severity and predicting patient outcomes in clinical research.
The parametric nature of the JSS facilitates the evaluation of treatment efficacy through data analysis.
