Differential Effects of Acute and Multiple Concussions on Gait Initiation Performance.

Objective: To identify the effect of acute and multiple concussions on gait initiation performance.

Design: Cohort study.

Setting: University research center.

Evidence of a conservative gait strategy in athletes with a history of concussions.

Background: A history of 3 or more concussions is frequently associated with numerous short- and long-term neuropathologies. Impairments in postural control are a known acute consequence of concussion; however, limited evidence exists on the effects of multiple concussions on gait. The purpose of this study was to assess gait stepping characteristics in collegiate aged student-athletes based on concussion history.
