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.

About

Sit To Stand

Read full description

Sit to Stand App is the first scientifically validated application for the biomechanics evaluation of the chair rising test based on high-speed video recording (240 frames-per-second). Sit to Stand App quickly and easily reports values of time, velocity, and muscle power of the sit-to-stand test. These variables are of great interest in the scientific and clinical fields for the early detection of functional changes associated with the aging process, as well as determining functional capacity in different populations. Sit to Stand App has passed several scientific validation processes. Their results have been shown to be equally valid as those reported by high-cost laboratory devices such as force plates or 3D video capture systems. Studies have shown how the results of the Sit to Stand App are related to frailty syndrome and determinants of sarcopenia in older adults. These findings make the Sit to Stand App a considerably useful pocket tool within the clinical setting. _______ Note: App Store screenshots generated with Screenshots.pro
