This algorithm is designed to produce a spinal cord injury classification consistent with the International Standards for Neurological Classification of Spinal Cord Injury developed and maintained by the American Spinal Injury Association (ASIA).
<!-- using IIFE -->
<!-- defines ISNCSCI on window object -->
<script src="https://unpkg.com/isncsci/iife/ISNCSCI.min.js"></script>
<!-- using ES module -->
<script type="module">
// using default import
import ISNCSCI from "https://unpkg.com/isncsci/esm/ISNCSCI.min.js"
// using named import
import { ISNCSCI } from "https://unpkg.com/isncsci/esm/ISNCSCI.min.js"
</script>Install library using NPM
npm i isncsci
Then import the library in your project
Named import
// Recommended with typescript
import { ISNCSCI, Exam } from 'isncsci';Default import
import ISNCSCI from 'isncsci';CommonJS
const { ISNCSCI } = require("isncsci");
// or
const ISNCSCI = require("isncsci").ISNCSCI;To get a classification and the totals, you just need pass an exam as a parameter while using the ISNCSCI constructor.
Interface for exam parameter can be found below.
Below is an example in TypeScript:
// create exam
let exam: Exam = {
deepAnalPressure: "Yes",
voluntaryAnalContraction: "Yes",
right: {
lowestNonKeyMuscleWithMotorFunction: "C8",
motor: {
C5: "5",
/* ... */
S1: "2*",
},
lightTouch: {
C2: "2",
/* ... */
S4_5: "1*",
},
pinPrick: {
C2: "1**",
/* ... */
S4_5: "0",
}
},
left: {
motor: { /* ... */ },
lightTouch: { /* ... */ },
pinPrick: { /* ... */ },
},
}
// get result
let result = new ISNCSCI(exam);
// output classification result
console.log(result.classification);
// output totals result
console.log(result.totals);Following shows the interfaces associated to Exam used for ISNCSCI constructor.
interface Exam {
right: ExamSide;
left: ExamSide;
voluntaryAnalContraction: BinaryObservation;
deepAnalPressure: BinaryObservation;
}
interface ExamSide {
motor: Motor;

}
interface Sensory {
C2: SensoryPointValue;

}Here lists the valid values for interfaces above.
Tagged values represents impairment due to non-SCI injury.
Single star (*) represents consider not normal for classification.
Double star (**) represents consider normal for classification.
