In the early 1990s, ankle braces began appearing more often on sports courts and playing fields due to their improved designs. They also cost less than repeatedly taping an athlete's ankle.

Now, ankle braces are available in various designs, including sport-specific options. But the goal is the same — to provide extra support after an injury or prevent an ankle sprain from occurring in the first place.

Coaches, parents and athletes often ask if wearing an ankle brace is worthwhile. Research shows that high school-age athletes who use ankle braces experience fewer ankle injuries. However, ankle braces don't reduce the severity of ankle, knee or other lower-extremity injuries.

How bracing works

Bones, muscles and a network of ligaments and tendons form internal supports that keep your ankle stable, flexible and strong. Ligaments are tough bands of tissue that stabilize joints and help prevent excessive movement.

Three main bones make up the ankle joint:

• Tibia — the long shin bone in your lower leg that provides the main weight-bearing surface at the roof of the ankle joint
• Fibula — the bone on the outside of the ankle that provides lateral and rotational stability
• Talus — the bone that provides the lower cartilage in the ankle and connects the ankle to the foot, functioning like a hinge to flex your foot

These internal supports link your foot all the way up to your hip. Ideally, they function as a unit.

Ankle braces serve as external supports to limit certain motions, such as plantar flexion/inversion, which is the movement at the ankle joint that points the foot downward away from the leg and turns the foot inward.

Braces also provide awareness of where your ankle joint is in space. For maximum effectiveness, ankle braces should fit comfortably in the shoes you wear during an activity, which also makes it more likely you'll wear the braces.

Rehabilitation plays a key role in recovery

If you do experience an ankle injury, weakness or instability, rehabilitation is a key component of your treatment plan. Often, when athletes still have ankle pain or aren't back to full function, it's because they haven't allowed enough time to heal properly. Rehabilitation providers specialize in balance, range of motion, strength and endurance, which are key therapy and training factors for recovery.

Performing exercises as directed helps ensure a safe return to activity and lessens the likelihood of reinjury.

Deciding if a brace is right for you

Keep in mind that wearing an ankle brace isn't a 100% cure-all or guarantee against injuries. Your healthcare team can help you make an educated decision about whether an ankle brace is right for you.
