Objective: To identify factors that predict running ability following traumatic brain injury (TBI), and to quantify per-formance thresholds for these predictors. Design: Cross-sectional cohort study. Participants: One hundred fourteen people with TBI. OutcomeMeasures: Self-selected walking speed, the high-level mobility assessment tool, postural stability (lateral center of mass displacement), ankle power generation at push-off and quality of gait performance (Gait Profile Score). Results: All predictor variables were all strongly associated with the ability to run. However, only self-selected walking speed contributed significantly to the final result. Investigation of performance thresholds for self-selected walking speed indicated that following TBI, people who walk at speeds of 1.0 m/s or higher are 16.9 times more likely of being able to run than for those who walk at speeds of less than 1.0 m/s. Conclusions: Self- selected walking speeds higher than 1.0 m/s greatly increase the likelihood of running following brain injury. The1.0 m/s threshold, although slower than able-bodied self-selected walking speeds, may be an important indicator of the ability to run in this population.
