ABSTRACT

Introduction: The prosthesis is the most used method for rehabilitating the amputee. Prosthetic adaptation requires knowing the biomechanical behavior of prosthesis users.
Objective: To evaluate the distribution of plantar pressure in patients with unilateral transtibial amputation and prosthesis users.
Methods: Transtibial amputee plantar pressure distribution was measured in static standing. Seven men with unilateral transtibial amputation, who were prosthesis users with liner and pin suspension, foot in high activity carbon fiber were the sample. Maximum and minimum pressure were calculated in the foot masks. ANOVA analysis of variance was used to investigate the variability of pressure in different regions of the foot.
Result: Data obtained from the pressure measurements of each mask show reliability (cr< 10%). The distribution of foot pressure was significantly different between masks for the ipsilateral side and the contralateral side (maximum and mean pressure p< 0.001). The highest pressure on the ipsilateral side occurred in region 4; and the lowest, in 3, on both feet. The posterior region on both feet supported higher mean and maximum pressure than the previous one. On the ipsilateral side, there is higher mean and maximum pressure in the medial region, in contrast to the contralateral side that is in the lateral region.
Conclusion: A distribution pattern of the plantar pressure is present in the standing position, with significant differences between both sides. The distribution of plantar pressure for non-amputees as proposed in the literature is different in amputees.
