Resumo
The amputee patient undergoes several changes after the amputation, not only physical
but also emotional and socioeconomic, requiring the use of prosthesis. One of the
physical changes that affects the amputee's gait when using your prosthesis ambulation
is compromised. The march is the natural way that humans use to move from one
location to another. The march is a complex activity because it depends on a series of
interactions between the two lower limbs multithreaded and total body mass. Therefore,
assessing the impact of the use of prostheses in locomotor through the analysis of
strategies for startup of the march transtibial amputees. We evaluated the speed and
displacement of the COP, knee and ankle angles of the support member during
initialization of the march. For the kinematic analysis was set 34 markers on anatomical
landmarks of interest, two AMTI force platforms. For statistical analysis we used the
Student t test and correlation between variables. Difference was only statistically
significant variables in the knee angle and average speed side. The absence of a flexible
ankle joint may result in limitations in the function of the prosthesis. Amputees to
achieve an adequate control in propulsion and balance it was necessary to use several
strategies to adjust. The prosthesis provided by SUS serves its purpose, which is to
provide a walking person. But this improvement in the ankle joint can facilitate the
process of walking boot. Another fact of great importance is the frequent evaluation of
prosthetic to verify the necessary adjustments of the prosthesis.
