Centre of Pressure Displacements in Transtibial Amputees

People with transtibial amputation, the stability is altered as a consequence of body part removed, including: the bone elimination, muscle tissue and somatosensory information and this causes transtibial amputees to have a high number of falls. It is necessary to know static stability and the indicators corresponding to this type of amputees, since it directly influences postural stability and the performance of various activities, including displacement, which directly affects the rehabilitation. Likewise, the information on stability in transtibial amputees is insufficient, and in amputees by land mines is null, the affectation suffered in the pressure center (COP) due to the type of amputation is unknown. A cross-sectional observational investigation was carried out in transtibial amputees due to trauma from landmines, people without amputation were also included, the COP was recorded in both groups to assess the upright position using the Romberg Test. Recorded data from amputee subjects differs significantly from non-amputee subjects. The first one shows an increase in biomechanical parameters related to stability, demonstrating that they make continuous use and more frequently compensation strategies to preserve stability when standing.
