I've tried several OKN apps and this is by far the simplest and the best. Change the speed you drag your finger across the even and it easily changes the speed the bars move. I can get it to any speed I want it at. Easy to go from black&white to red&white to shapes to kids images. ★★☆☆☆ Will notactivate on a smart Phone, Samsung S7. ★★☆☆☆ its a pain to get the speed set just right - wish there was a way to easily adjust it. itd also be great to have a timer feature where it stops after a set amount of time. if i hadnt already paid for the app, id just use one of the free ones. sorry to write such a gripey review ... i just get frustrated almost every time i use it! ★★☆☆☆ no easy way to change image from color to color Google Play Rankings This app is

On indirect assessment, based on measuring postural sway or assessing the performance in perceptual tasks such as the subjective visual vertical [16, 19, 20].It has been hypothesized that visual dependence is related to an alteration of the weighting of the sensory cues in the central processing network that generates a sense of orientation [14, 16]. Motor readouts of the activity of this network during the processing of full-field visual motion stimuli are optokinetic nystagmus (OKN) and after-nystagmus (OKAN) [21, 22]. OKN is a reflexive eye movement driven by the motion of the visual field on the retina, so-called retinal slip [23]. It consists of nystagmus with slow phases in the same direction as the moving stimulus and quick phases in the opposite direction. During natural full-field visual stimulation, the nystagmus is a combination of OKN and smooth-pursuit eye movements. The smooth pursuit eye movement system allows to voluntarily track moving targets by keeping their image on the fovea. If during an optokinetic stimulus, the light of the room is suddenly extinguished, the nystagmus continues for a while. As the smooth pursuit component stops within seconds, the velocity of the slow phases rapidly drops to then slowly decays to zero. The latter phenomenon is known as OKAN and can only be properly measured under laboratory conditions using large visual stimuli (e.g. optokinetic drums [23,24,25]) to drive the OKN before extinguishing the light. It is currently believed that the command signal for the OKN is generated through the central processing network integrating visual, vestibular, and proprioceptive information to provide an estimate of self-motion. This network, traditionally known as the velocity storage mechanism (VSM), can be characterized by a single time constant, i.e. a parameter measuring the time it takes to discharge a loaded velocity input. OKAN is a direct expression of the velocity storage and it can be characterized by the VSM time constant and gain, weighting the VSM contribution in the overall OKN response. OKAN, however, is rarely tested, as it is considered poorly localizing [24] and its measurements show high trial-to-trial variability [25].Considering the reports on concussed patients who present symptoms compatible with visual dependence [12, 13], we hypothesized that in selected concussed patients with persisting, strong dizziness after visual stimuli the VSM is overacting when it extracts self-motion information from visual cues. To evaluate this hypothesis, we analysed OKAN of patients who showed signs and symptoms supporting impaired central integration of visual information after a concussion.Materials and methodsSubjectsData from 71 concussed patients (17 females, 30.4 ± 9.1 years old, mean ± standard deviation) whose evaluation at the Swiss Concussion Center (SCC) included OKAN testing between 01/01/2016 and 31/12/2018 were analyzed. Neurologists at the SCC ordered OKAN testing whenever a concussed patient suffered persistent visual-vestibular symptoms suggesting an increased visual dependence. The time span between head impact and OKAN testing varied between 6 and 4172 days (363 ± 629 SD). Standard CT or MR imaging in these patients were negative for traumatic lesions. In addition to the neurological examination, the
