- Аннотация: Children who survived cerebellar tumor occur with atactic motor dis-orders. These disorders could be represented in postural, locomotor and oculomotor domains. The gait efficiency depends on visual information acquired from saccadic eye movements. The aim of the study was to establish the relationships between measures of tandem gait and saccades and to verify them by stabilometry and general motor score using Bruininks-Oseretsky Test. We used motion capture system (Optitrack) for gait registration and Arrington eye tracker for saccade detection. 15 patients (9–17 years old) survived cerebellar tumors and stayed in rehabilitation center, participated in the study. We found significant relationships between the parameters of tandem gait and saccades: high percent of hypermetric saccades (saccades which overshoot the target) was strongly associated with high tandem gait variability (r = 0.552). Moreover, the degree of impairment of gait and saccadic parameters significantly related to worse postural disturbances (r = 0,752; r = 0.541) and motor skills (r = -0,673; r = -0,612). Observed findings comprehensively characterize the severity of ataxia and could provide new approach for the diagnosis of CNS lesions.
