Ankle braces are being used as an alternative to ankle taping in preventing and supporting the ankle after ankle sprains. Ankle sprains are one of the most common sports related injuries in the United States affecting millions of people on an annual basis. Ankle sprains usually occur when someone lands from a jump on their toe with their ankle turned in an inward position, a position known as inversion. The mechanism of injury usually results in damage to the outer portion of the ankle joint since the ligaments on the inside of the ankle joint provide the ankle with more stability.
Two different types of ankle braces are available. The two types of ankle braces are: 1) non-rigid functional brace and 2) semi-rigid pneumatic brace. Both braces can provide ankle support while allowing ankle range of motion, continued athletic participation and support to the hindfoot and ankle joint. These braces, which are used inside of the shoe, are self applied and are relatively low in cost. When used for prevention of ankle injuries, ankle braces can allow for better position sense.
What to Look for
Non-rigid functional braces usually have laces or Velcro closures. These braces are best used for ankle sprains at different stages of recovery, including chronic injuries. Semi-rigid pneumatic braces, frequently called by their trade names of Aircast or Air-Stirrup, are used for acute ankle sprains, but they can also be used for recurrent ankle sprains and chronic injuries to the ankle joint and hindfoot. Many find semi-rigid pneumatic braces to be most helpful since they play a role in the resolution of ankle swelling and several studies support their use in the prevention of ankle inversion. These braces allow for predictable results and early function in the ankle joint.
Both braces should be obtained from a surgical supply store to allow for the appropriate size to be selected to support the ankle joint. Also, this will allow you to find the brace with the most comfortable fit.
Common Pitfalls
While both braces provide support to the ankle and hindfoot regions, neither brace type provides rotational control through the ankle. Also, many people find the semi-rigid pneumatic braces to be bulky in their shoes.
