Biomechanics is an interdisciplinary science that can be defined as the unification of physics and biology, consideration of the influence of dynamics and statics on the function of the locomotor system and, ultimately, the application of the aforementioned in solving medical problems. Biomechanics allows us to obtain more precise results on the basis of which we can determine various deviations from the physiological movements of the locomotor system and by which we can more successfully establish and adjust the therapy according to the patient's needs. The basic function of the locomotor system is to enable movement and provide mechanical support to the body. Bones are levers that are affected by muscles on one side and gravity on the other. The centers of rotation are located in the joints. Force generated by muscles opposes the weight of the observed part of the body in order to maintain balance. The statics and dynamics in the analysis of movement and posture are very closely connected and it is difficult to understand one without the other. Kinematics describes motion from the perspective of position and time. Kinematic analysis is very useful in validation of lameness and gait symmetry. It is based on two-dimensional and three-dimensional motion recording and measurement of displacement, joint angles, velocity, and acceleration. Kinetics studies motion through forces that occur when a body moves. Kinetic analysis is focused on the generation of the vertical and horizontal force, while the limbs are in contact with the ground, the load rate, and the force distribution. These indicators can be indicators of lameness, the degree of load on each limb while standing or during the different phases of movement. In general, biomechanical analysis provides parameters that are crucial for the diagnosis of pathological conditions of the locomotor system, elimination of these conditions and return to physiological values. There are various methods used for physical therapy of animals. Therapeutic exercises that restore range of motion, balance, mobility and strength play a major role in rehabilitation. Knowing their advantages from a biomechanics point of view makes our selection much easier.
