Ankle bracing has been used for many years in an attempt to prevent lateral ligamentous injuries of the ankle by restricting joint range of motion (ROM).
To examine the influence of ankle bracing on ROM and sport-related performance.
Repeated measures.
Biomechanics laboratory.
30 volunteers. None reported ankle trauma within 2 years preceding the study or had other orthopedic conditions that would have affected physical performance.
Three brace conditions (McDavid A101™, Perform-8™ Lateral Stabilizer) were assessed during performance of the vertical jump and shuttle run.
shuttle-run time, vertical jump height, inversion, and plantar flexion ROM.
Both braces restricted plantar flexion and inversion ROM and caused no change in shuttle-run time or vertical jump height.
Our results indicate that bracing the ankle joint increases external lateral support to the joint without significantly restricting functional ability.
