Description

This application is used to help assess an individual's subjective visual vertical. It is administered identically to the traditional "bucket test", but instead utilizes the accelerometer in the phone for a more accurate angle measurement. The individual can respond by pressing a Bluetooth button (a 'selfie stick' or 'shutter button') purchased separately from a 3rd party. The tester can also click on the screen to record the response angle if a button is not available.

In addition, the device has several advantages over traditional angle-finder bucket testing; the application automatically prompts the tester to set the bucket to certain randomized presets, stores all of the responses for a given test, and computes the average and variance of responses at the end of 6 trials.

Included in this application are the tester application itself as well as two PDF documents describing administration of the test and creation of the bucket respectively.

DISCLAIMER:

This application is provided and intended for educational purposes only. It is not intended to be a substitute for professional medical advice, diagnosis, or treatment. If you believe that medical advice, diagnosis, or treatment is needed, you should immediately seek professional medical advice from your physician or other qualified healthcare provider. You should call 911 immediately if you think you are having a medical emergency.

All measurements made by this device are to be left to the interpretation of the user. These measurements may be useful to consider in assessment of vestibular dysfunction such as dysfunction arising from unilateral vestibular damage or concussion.

This application and its uses were conceived at the University of Alabama at Birmingham (UAB) by the Vestibular Ocular Research Clinic (VORC) during their investigation of peripheral and central vestibular function in concussion. The VORC researchers conceived, developed, and are in the process of validating the data collected by this application. Publications utilizing this device will be added to the description as they become available.
