To identify factors that predict running ability following traumatic brain injury (TBI), and to quantify performance thresholds for these predictors.
Cross-sectional cohort study.
One hundred fourteen people with TBI.
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).
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.
Self-selected walking speeds higher than 1.0 m/s greatly increase the likelihood of running following brain injury. The 1.0 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.
确定预测创伤性脑损伤（TBI）后跑步能力的因素，并量化这些预测因素的性能阈值。
横断面队列研究。
114 名 TBI 患者。
自我选择的步行速度、高级移动评估工具、姿势稳定性（横向质心位移）、蹬离时的踝关节功率产生和步态表现质量（步态分析评分）。
所有预测变量都与跑步能力密切相关。然而，只有自我选择的步行速度对最终结果有显著贡献。对自我选择的步行速度的性能阈值的研究表明，TBI 后，以 1.0m/s 或更高速度行走的人比以低于 1.0m/s 速度行走的人更有可能跑步。
自我选择的步行速度高于 1.0m/s 大大增加了脑损伤后跑步的可能性。虽然 1.0m/s 的阈值比健康人自我选择的步行速度慢，但对于这一人群的跑步能力可能是一个重要的指标。
