Visual Vertical vs Verticality Test

Visual Vertical makes high-grade subjective visual vertical (SVV) testing accessible to every practitioner — no expensive equipment required. SVV testing is a sensitive, validated measure for brainstem lesions and otolithic dysfunction, widely used in neurology and vestibular rehabilitation. Until now, accurate testing required bulky, costly apparatus. Visual Vertical changes that: all you need is your iPhone, a bucket, and a small piece of Blu Tack. How it works Mount your iPhone inside the bottom of a bucket using Blu Tack. The patient holds the bucket to their face and adjusts a line on screen until it appears vertical to them. The app records the deviation and calculates your result — accurate readings in minutes, at a fraction of the traditional cost. What you can measure - Left eye, right eye, or both eyes open - Single readings or full sequences across all conditions - One or three readings per condition, with automatic averaging Clean, minimal results screens make it easy to record and communicate findings.

With Verticality test you can perform easily the verticality perception, horizontality perception and profundity perception tests with all the mobility advantages of your iOS device. We developed a new methodology to allow you to perform the tests at any location with any illumination. For a classical performance of the tests you can use the tvOS version on an AppleTV 4thGen. Verticality and horizontality perception tests are well known medical tests to measure the otolithic function. WARNING: Verticality Test is not a medical device
