Gait characteristics refer to the characteristics of the size, direction and action point of pedestrian walking force reflected in footprints. It is a reflection of people's walking habits in the stages of landing, starting and supporting swing. Generally including: knock marks, tread marks, push marks, stagger marks, seat marks, force marks, indentation marks, screw marks, lift marks, push marks, dig marks, pick marks, swastika marks, scratches, scanning marks, scratches, etc.

Heel gait: when walking, the feet follow the ground, and the gait is unstable, showing that the body is gently shaking from side to side, the feet are outstretched, and the arch is high. It can be seen in patients with tibial nerve paralysis, achilles tendon rupture and hereditary ataxia. Gait in circles: when walking, the legs and knees are stiff, the feet are slightly drooping and the toes are hooked. At first, turn to the healthy side, lift the affected pelvis and lift the affected limb, then take the affected hip joint as the axis, rub your legs straight and draw a semicircle to the outside, and take a step forward. Because it is more common in patients with spastic hemiplegia of lower limbs, it is also called "hemiplegic gait".
