Análise cinemática da marcha de pacientes com amputação transfemoral e transtibial protetizados

Abstract

Objective: To analyze the linear kinematics of gait in transtibial and transfemoral amputees. Methods: Descriptive and observational research, carried out in the gait analysis laboratory of Block 70 of the University of Caxias de Sul. Sample consisting of 30 patients, aged over 20 years, divided into 3 age-matched groups (Group A: Individuals with transtibial amputation; Group B: Individuals with transfemoral amputation; Group C: healthy individuals). For gait assessment, a kinemetry system with 7 integrated cameras was used. The linear kinematic variables analyzed were speed, cadence, stride time, single support time, double support time, stride length and stride width. For data analysis, descriptive statistics, independent t test, ANOVA test with Tukey's Post Hoc, and Pearson's chi-square test (⩽00.05) were used. Results: When comparing the 3 groups, there was a statistically significant difference in the variables speed (p⩽00.00), cadence (p⩽00.04), stride time (p⩽00.00), double support time (p⩽00 .04) and stride length (p⩽00.04). Between transtibial and transfemoral there was a significant difference in the time of double support (p⩽00.00). There was a difference between transtibial and controls in the variable speed (p⩽00.00) and between transfemoral individuals and controls, in the variables speed (p⩽00.00), stride time (p⩽00.02) and double stance time (p⩽00.00). Conclusion: It is concluded that there is a difference in linear kinematics of gait between amputees and the control group, and the higher the amputation level, the greater the gait deficits.
