Ankle braces are devices that can be used to support weakened or injured ankles, or to prevent ankle injuries from occurring. There are a variety of different types of ankle braces available on the market, but they all work by stabilizing the ankle joint and preventing the foot from moving too far in any one direction. This can help to protect the ligaments and tendons around the ankle from overstretching or tearing. In addition, an ankle brace can also help to relieve pain and swelling by providing compression and support. While an ankle brace is not a cure for an ankle injury, it can be a helpful tool in the treatment and prevention of ankle problems.
