P&O Comet vs Subjective Visual Vertical SVV

The Clinical Outcome Measures Electronic Toolkit (COMET) provides a library of fifteen useful clinical outcome measures for prosthesis and orthosis (P&O) users and clinicians. COMET simplifies and standardizes the use of outcome measures for daily clinical practice by enabling practitioners to easily select the appropriate measure, administer the test(s), and immediately receive the results as a printable/exportable PDF document to inform evidence-based clinical care and to be included in the patient’s electronic health record. © 2021-2023 Orthocare Innovations, LLC.

Subjective Visual Vertical turns your iPhone into a simple tool for checking how well a person can set a line to true vertical using sight alone — a quick way to screen for inner-ear (otolith) and balance differences. The app shows a line and uses the phone's motion sensors to know which way is truly vertical. The patient adjusts the line until it looks upright to them, and the app reports how far that is from true vertical, in degrees. TWO WAYS TO TEST • Bucket mode — fix the phone inside the base of a bucket with reusable putty, screen facing in. The patient holds the open rim to their face so the room is hidden, then turns the bucket until the line looks straight. • VR mode — drop the phone into a VR viewer or Google Cardboard. The line is shown to each eye in a split view. The patient turns the line with on-screen buttons or a Bluetooth remote and locks it in when it looks vertical. FLEXIBLE TESTING • Choose the right eye (OD), left eye (OS), both eyes (OU), or all in turn. • Run a single measurement or repeat each condition several times. • Set the trial length and the pause between trials. • Repeated trials are averaged automatically, with the standard deviation shown. CLEAR RESULTS • See the deviation in degrees for each eye, with a simple diagram of the perceived vs. true vertical. • Share the numbers as text, with no image attached. • In bucket mode you can record a photo or video of the trial with the true and perceived vertical lines drawn over it, and a date-and-time label. Media is saved to your own Photo Library. • Customisable line and background colours. • Right eye (OD) listed first, by convention. • Works with a Bluetooth remote so the line can be turned while the phone is sealed in a viewer. • Everything runs on the device. No account, no sign-in, no tracking. IMPORTANT This app is for educational purposes only and should not be used for clinical diagnosis or treatment decisions.
