The previous function patterns cannot be applied for the individual with a partial amputation of the lower limb (also of the upper limb). The walk re-education requires careful definition of all abnormalities in the patienťs gait that differ from the standard pattern of muscle activity and the proper movement of joints. It is valid also for the patients with lower limb amputations executed between the knee joint and the ankle joint, i.e.trans-tibial amputation. A wide spectrum of biomechanical methods is utilized for a complex analysis of movement in orthotics and prosthetics (a combination of kinematic and dynamic methods, complemented with EMG and with the measuring pressure on the body contact with the ground). Their application serveš for the comparison of various types of the prosthetic feet, as well as for the assessment of health condition, intensity of movement activities, etc. The main task is to analyse movement and to specify the load bearing on the sound limb. Biomechanics has an important pláce in the multidisciplinary team, which is essential for the complex care of trans-tibial amputees.
