Instrumented gait analysis of traumatic transtibial amputee patients

Presented study gives findings of quantitative gait analysis and evaluation of different adaptive strategies of body in 12 traumatic transtibial amputee patients with prosthesis. Gait analysis consists of kinematics, ground reaction force kinetics, multichannel surface electromyography of quadriceps and hamstrings of amputated and non-amputated legs. Results of gait analysis discloses asymmetries in gait parameters between the amputated and sound legs, as well between transtibial amputees and non-disabled persons. Kinematic results showed that the ankle kinematics of prosthetic limb are significantly reduced while hip flexion are increased in late stance phase. Temporal spatial parameters were different: prosthetic stance phase (ms and % GC) was shorter, swing phase and prostetic step lenght were significantly prolonged. Walking speed of amputees was slower. Results of kinetic analysis shows decreased ground reaction (vertical Fz1 and Fz3, fore.-aft and medio-lateral Fy1 and Fy2) under prosthetic limb while sound limb has larger magnitude of vertical force Fz2.
