Clinical assessment of the gait video-analytic profile

We propose a system for the diagnostics of postural disturbances that may be revealed in the frontal surface with an original complex of motion video-analysis, with allocation of video-analytic profile of the ankle-joints. Main group comprised 19 patients with cerebellar ataxia, and control group comprised 18 healthy individuals without coordination problems and pathology of musculo-skeletal locomotor system. In this study, we determined diagnostically significant and distinguishable video-analytic criteria of the “over the target” peak for patients suffering from cerebellar ataxia: 1) amplitude of foot raising over the surface of the “diagnostic step”; 2) time of foot placing on the surface of the “diagnostic step”; 3) speed of foot descent on the surface of the “diagnostic step”; 4) ration of time of execution of foot raising to total time of execution of the movement “Step”; 5) presence of additional peaks in the support period, which is of importance in the diagnosis of cerebellar disturbances.
