Gait is the motion of trunk for stepping from one place to another. In order to walk for a long time without getting tired; brain, spinal cord, peripheral nerves, muscles, bones and joints must work together, joint movements, time and strength of contraction should be sufficient. Due to the complexity of regular walking and the difficulties of evaluation with naked eye, modern gait analysis systems have been developed for assessment of walking difficulties. Recently, modern analysis is carried out via motion analysis laboratories. In order to make gait analysis of the individuals, detailed anamnesis form must be filled, clinical evaluation, video analysis and kinematic-kinetic analysis must be performed. All results must be evaluated with the software developed for this purpose. As a result of all these operations, graphical data obtained from the frontal-sagittal and transverse planes of the body segment during gait cycle is evaluated.
