Does prior concussion lead to biomechanical alterations associated with lateral ankle sprain and anterior cruciate ligament injury? A systematic review and meta-analysis.

From the study:
“WHAT IS ALREADY KNOWN ON THIS TOPIC
⇒ Gait alterations have been observed after returning to sport following a concussion.
⇒ Individuals may be more vulnerable to subsequent injury following concussion.
WHAT THIS STUDY ADDS
⇒ The decreased postural stability and locomotion-related performance following concussion are linked to an increased risk of lateral ankle sprain (LAS) injury.
⇒ Compared with individuals without a previous concussion, individuals with a concussion history display a more erect landing posture with similar sagittal plane internal joint loading during landing, and exhibit greater internal joint loading and comparable joint kinematics in the frontal plane, both of which are associated with anterior cruciate ligament (ACL) injury.
⇒ The addition of cognitive demands into jumplanding tasks following concussion increases frontal plane kinematics that could be linked to ACL injury risk.
⇒ The unfavourable locomotion-related performance and sagittal plane kinematics after a concussion persist regardless of the addition of cognitive demands in motor tasks.
HOW THIS STUDY MIGHT AFFECT RESEARCH, PRACTICE OR POLICY
⇒ Based on current findings, adding cognitive demands into jump-landing tasks is essential to identify the frontal plane biomechanical alteration associated with ACL injury risk; therefore, we recommend that clinicians include cognitive demands into motor function evaluations to inform decision-making of return-to-play following concussion.
⇒ To develop effective rehabilitative interventions, future research is warranted to investigate the underlying mechanism of biomechanical alterations following concussion that are associated with elevated LAS and ACL injury risks.”
