Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Summary

Ankle braces may slightly impair functional performance in physically active individuals, potentially increasing agility times and decreasing jump height. However, most tasks show no significant performance difference when braced versus unbraced.

Area of Science:

Sports Medicine
Biomechanics
Rehabilitation Science

Background:

Ankle sprains are common, leading to the development of ankle braces for prevention and treatment.
Existing research on ankle braces primarily focuses on injury prevention, with less evidence on functional performance impacts.

Purpose of the Study:

To investigate the effects of ankle braces on functional performance measures in young, healthy, and physically active individuals.
To aid sport rehabilitation specialists in making informed clinical decisions regarding ankle brace use.

Main Methods:

A critically appraised topic (CAT) methodology was employed.
Literature search included a minimum of Level II evidence research studies.
One randomized controlled trial and three prospective cohort studies were selected for analysis.

Main Results:

One study reported significantly increased agility run times when participants wore ankle braces.
Another study found a statistically significant decrease in vertical jump height and ankle range of motion with brace use.
Most other functional performance measures showed no significant differences between braced and unbraced conditions.

Conclusions:

Ankle braces may lead to varied functional performance effects in young, healthy, and active individuals.
Bracing generally does not significantly impair most functional tasks but can increase agility times and decrease jump height.
Potential deficits in ankle range of motion (plantarflexion, dorsiflexion, eversion, inversion) may underlie observed performance decrements.
