Mild Traumatic Brain Injury Is Associated With Increased Dual-Task Cost During Ambulation: A Preliminary Study

Objective The aim of the study was to determine the impact of dual-task conditions on mobility after mild traumatic brain injury. Design Eleven adults with mild traumatic brain injury within 1 wk of injury and 10 age- and sex-matched healthy controls completed gait trials with a single-task condition and three separate dual-task conditions: counting by 1 (low), serial subtraction by 3 (medium), and alternating letters and numbers (high). Dual-task cost was calculated as dual-task cost = ([dual-task performance] – [single-task performance]) / [single-task performance] × 100%. Results Participants with mild traumatic brain injury ambulated slower than control subjects (P
