Efeito da adição de peso no tronco sobre a cinemática da marcha de um sujeito com ataxia

Abstract

The ataxia is characterized by incoordination when walking and is a symptom of Machado- Joseph disease (MJD). There are few case reports of ataxia describing possible ways to improve gait in this population, thus justifying the need of the present work. The purpose of this study was to describe the effect of trunk weight adding on gait kinematics in an subject with ataxia. The data collection was carried out in three steps, without using any vest and with the use of vests, model A and model B. The Model A gabardinado tissue and model B of waterproof and lined with velcro, made on measure material. To obtain data of the studied variables the kinematics VICON system was used. The main findings were that, for the situation with the vest A occurred a shorter uni foot support and a longer bipedal support, compared to the situation without a vest. In relation to gait velocity was observed that the rate was higher in the situation with the vest B. On the other hand the situation without vest, the subject had a greater step length and shorter step width, not presenting major changes to the right and left step length, i.e., the step was symmetrical. Therefore can be concluded that, adding weight in the trunk as used in this study did not prove be beneficial for the gait kinematics.
