According to the pattern of soft tissue healing, it is generally divided into 3-3-3 weeks of functional exercises. 6-9 weeks focus on the full range of active and passive ankle mobility exercises, strengthening the ankle joint muscle strength exercises, partial weight-bearing exercises (foot on the ground), and walking exercises. Passive joint mobility exercises: 1. According to the conclusion of the physician’s review, the assisted passive ankle dorsiflexion and plantarflexion exercises gradually became the same as the healthy side. 2. Assisted passive ankle inversion and valgus: slowly perform ankle inversion and valgus exercises once a day in each direction with the cast removed or with the brace removed, and hold for 30 seconds with a slow pull to the range of slight pain. Gradually with time, the mobility is the same as that of the healthy side. 3.Please apply ice pack for 20 minutes immediately after the passive joint mobilization exercises. 4.If the swelling of the joint is obvious, dorsiflexion (hooking the foot) and valgus (instep outward) can be practiced in the morning, and plantarflexion (stepping downward) and inversion (instep inward) can be practiced in the afternoon to prevent overstimulation. Active mobility exercises: 1, ankle active dorsiflexion, plantarflexion, inversion, eversion in all directions within the range of micro-pain activities, hold the limit at 5 seconds and then relax, 10 / group, 1-2 groups / day. 2.Try to actively grasp the towel training: the towel is spread on the bed surface, the foot steps on the side of the towel, and actively grasps the towel with the toes so that the towel gradually shrinks. 3, the ankle joint inside and outside of equal length contraction exercises: foot little finger and the ankle at the wall or hard object blocking surface, active ankle turning force and blocking object resistance but not make the ankle joint activities, the opposite direction of the inward turning force the same way. The extreme angle lasts for 5 seconds and then relax, 10/group, 2-3 groups/day. Weight-bearing exercises: the healthy side of the patient’s foot on a hard object, the affected side of the foot on the scale, the height of the hard object is the same as the height of the scale, the center of gravity of the body tends to be on the affected side of the affected side, the affected side of the foot stepped on the scale, 10% of the body weight of the weight of the weight of the weight of the beginning of the pressure, with the time and the affected side of the ankle pain tolerable range of gradual increase in the weight of the body weight of the pressure of the affected side of the body weight of the affected side of the ankle joint each week can be increased by 10% more pressure until the end of the final one-legged stance. Walking exercises: 1, three-point gait walking: after weight-bearing exercises, the patient tries to walk alternately with the affected foot and the crutches on the ground at the same time, and the healthy leg off the ground swinging. 2, two-point gait: when the affected side of the weight-bearing exercises more than 50% of the body weight, then the healthy side of the crutches, start to try the affected side of the foot and the healthy hand crutches at the same time on the ground, the healthy side of the leg off the ground swinging, alternating walking.
