Weight-Bearing Dorsiflexion Range of Motion and Landing Biomechanics in Individuals With Chronic Ankle Instability.

Context: People with chronic ankle instability (CAI) exhibit less weight-bearing dorsiflexion range of motion (ROM) and less knee flexion during landing than people with stable ankles. Examining the relationship between dorsiflexion ROM and landing biomechanics may identify a modifiable factor associated with altered kinematics and kinetics during landing tasks.

Objective: To examine the relationship between weight-bearing dorsiflexion ROM and single-legged landing biomechanics in persons with CAI.

The effectiveness of prophylactic ankle braces in reducing the incidence of acute ankle injuries in adolescent athletes: a critically appraised topic.

Clinical Scenario: Ankle injuries constitute a large number of injuries sustained by adolescent athletes participating in high school athletics. Prophylactic ankle bracing may be an effective and efficient method to reduce the incidence of ankle injuries in adolescent athletes in the secondary-school setting.

Clinical Question: Do prophylactic ankle braces reduce the incidence of acute ankle injuries in adolescent athletes?

Summary Of Key Findings: Two of the three included studies reported that prophylactic ankle braces reduced the incidence of ankle injuries compared with no ankle bracing.
