After ankle surgery, functional exercises of the ankle joint should be performed by first applying heat before rehab. This is because hot compresses can increase the blood flow to the ankle joint and facilitate the ankle joint to do stretching exercises. Secondly, you can let the tissues and muscles around the ankle joint do stretching training, and start stretching training after 10-15 minutes of hot compress. The intensity of training should not be too large, but should be gradually lengthened and the treatment cycle should be long to avoid aggravating the underlying disorder. Then you can do isometric contraction tension training, because the ankle joint is unstable after long-term disuse or injury, so you can do isometric contraction tension training to effectively improve the stability of the ankle joint. During training, you can use rubber bands to increase the training resistance to enhance muscle strength and muscle tension. The training process should pay attention to the balance of muscle force in all directions of the ankle joint. When the stability of the ankle joint is improved, the ankle brace can be gradually removed. After the training, you can apply hot compresses of Chinese herbal medicine. Choose Chinese herbal medicine mainly from Haitongpi soup, choosing Haitongpi, Xanthopia, Lutong, Wei Lingxian, Mulberry, Gui Zhi, Qiangwu, Dushu, Fangfeng, and Xingjian. In the daily functional exercise, we should pay attention to avoid running for a long time, avoid doing rush stop exercise, do aerobic training appropriately, not jumping on trampoline, avoid climbing stairs with the front of the foot, and avoid repeatedly stepping on the treadmill.
