Instrumental computing and software tools have been developed for constructing a nonlinear dynamic model of the human oculo-motor system (OMS) based on data input-output experiments using test visual stimulus innovative technology. Volterra in form multidimensional transition functions 1st, 2nd 3rd orders, taking into account inertial properties OMS was used as identification tool. Eye-tracking...

Cerebellar dysfunction may result in significant functional difficulties with upper and lower limb movement, oculo-motor control, balance and walking. Such difficulties can affect employability, increase carer burden and reduce a person’s perceived quality of life. The economic burden of people with spinocerebellar ataxia is estimated to be around E18 776 per annum. This article will review the...
