What is 10mwt
A timed ten meter walk test is a clinical measurement. It is used by healthcare providers to assess functional mobility, gait, and vestibular function in the course of treatment for many conditions as well as in healthy persons.
Such measurement helps document and quantify quality of life changes in patients treated for brain and spinal cord injuries, stroke, fractures, amputations and aging.
Traditionally the test has been administered with a stop watch and recorded on paper. You can see the test being administered this way in this video. The measurement is repeated three times per patient in order to take a reliable average. This can be time consuming and prone to delay in adding results to electronic records.
However the trend in healthcare is that busy practitioners need to save time while maintaining or improving quality of care for patients. Every part of practice that can be shifted to mobile devices and integrated with patient management systems is a boon to providers.
The 10mwt software provides a simple way of administering the test on a phone, tablet, or any device with a web browser. It combines the measurement and record keeping into one time saving method.
The test results can be conveniently posted to any patient management system that exposes a simple web based API method. When an API is not available the test results can just as easily be copied to the clipboard for pasting into any available application.
I started the earliest version of 10mwt a year ago upon first hearing about the test and its use in orthotic and prosthetic practices. My main goals for the tool were that it would (1) be free to use and (2) easily work alongside any variety of other healthcare IT systems.
After more than a year of real world experience working within the field of software for orthotic and prosthetic clinics I decided to update the original tool as follows.
New Features Added
Port the tool to Express
The original tool was a single html page with an embedded JavaScript app. Moving everything into a familiar web framework allows for easier installation for the user and smoother maintenance for developers going forward. The main changes here entailed implementing routing, a view template, and static serving of JavaScript resources. All fairly straight forward using Express.
Save patients in local storage
Originally 10mwt was seen as standin mainly for the clinician's stopwatch. It did not save test records between uses. With this update each set of time trials is saved locally on the device until the clinician decides to delete them.
So it is now possible, for example, to administer tests for several patients in a day and come back to the results the next day to post the results at a convenient time for such paperwork. This was accomplished using the localForage API for local browser storage. See these lines in the repo.
this.saveViewModel = () => {
let flattenedTests = thisViewModel.tests().map(t => ko.toJSON(t));
localforage.setItem('10mwt', flattenedTests);
};
Adding the ability to POST to any API
Cut and paste can be a handy way to move text from document to document or even between different systems. But a better feature is to send information wherever it needs to be with one click. With this update the latter is now part of 10mwt. It's accomplished by setting a URL to any web hook that can receive a POST request.
It's done with a simple AJAX request. See these lines in the repo. The narrative test results are inserted into the POST body. Processing the information is up to the server.
this.postNarrative = function() {
console.log('Posting...');
$.post(
tests.url(),
ko.toJSON(
'When assessed with the 10-meter walk test, ' +
thisTest.id() +
' had a ' +
thisTest.gaitText() +
' walking speed of ' +
thisTest.averageGaitSpeed() +
' m/s today.'
),
() => {
console.log('Post complete.');
tests.showMessage('Narrative posted.');
setTimeout(() => tests.showMessage(false), 750);
},
'text'
);
}
Improved Responsive Layout
Earlier versions of 10mwt relied on the Skeleton css framework which is light weight but limited. The old version worked well in a full web browser, but very often a clinician on the go will want to use a smaller device like phone or tablet when moving from exam room to room. Going forward 10mwt implements Bootstrap 4 and takes a mobile first approach.
The New User Interface
The Former User Interface for Comparison
This was accomplished mainly through considerable changes to the view templates.
