The specific methods of using ankle brace are as follows: 1. Choose the right size, avoid too big or too small, which cannot achieve the role of ankle protection. 2. Pay attention to the process of using ankle brace, if there is obvious local swelling, the ankle brace should not be fixed too tightly, otherwise it will compress the blood vessels and produce serious swelling and toe ischemia, if there is no obvious swelling, only pain, you can fix the ankle brace too tightly. The ankle brace can only be used to protect the ankle joint and cannot be used to walk with weight. 4. The ankle brace can be used continuously at night to avoid further ankle injury due to improper posture during sleep.
