Plantar pressure is affected by internal factors (foot structure and function - foot arch shape, direction of body axis compared to gravity, projection of COP centre to supporting position, position of the femur head in the hip joint acetabulum and position and configuration of the axis organ) and external factors (inclination of supporting foot, its profile, friction properties of the pad and the shoe ...). Hypokinesia and influencing the foot or whole lower extremity by different inputs can change the dynamic characteristics of gait.
