The analysis of the gait and posture is useful for the study of hereditary ataxias. The clinical test does not offer objective information of alterations of its parameters. Instrumental methods provide quantitative measures to describe progress disorders and posture. The main instrumental methods used are the movement capture videographic, the pressure sensitive gateway system GaitRite and the inertial sensor system APDM Mobility Lab. The most reported alterations in patients with ataxia are decreased cadence; stride length, gait speed, increase in double support of lower limb, length and acceleration of postural sway. The most advantageous method is the system of inertial sensors. The alterations detected with instrumental methods provide valuable information in the early detection of ataxias, their progression and to measure the response to therapeutic interventions.
