The use of an ankle brace for Peroneal Tendonitis or Tendinosis, called also ankle Tendinitis, is intended to alleviate ankle swelling and pain. The type of ankle support to wear would differ based on the purpose of use. To recover from an already incurred injury, use a rigid Peroneal Tendonitis brace. To wear one as a support for prevention, you can pick a soft ankle brace.
Ankle Tendonitis is the inflammation of Peroneal Tendons. These two tendons are located near the ankle joint, on the outer side of the feet. A Peroneal Tendon main function is to stabilize your foot and ankle, by attaching together muscles and bones. An ankle Tendinitis occurs following an overuse of the ankle from repeated motion. Per example, Marathon runners are more exposed to this type of ankle injury than other athletes.
In addition to ice and rest, using an ankle support would help to find recovery much faster.
Wearing an ankle brace during physical activity as an ankle protection would unload pressure on your ankles. It reduces the likelihood of an ankle Tendonitis.
