Striking an obstacle while walking can be dangerous, reflecting the higher risks of losing one's balance, tripping and falling. Particular situations during which internal resources are limited, such as in a fatigued state, may impair performance when crossing obstacles, enhancing the risks of falls or accidents. Our goal was thus to review the effects of experimentally-induced fatigue (EIF) on gait parameters during obstacle crossing by healthy individuals. We systematically searched PubMed and Web of Science databases using 'fatigue', 'obstacle crossing' and their equivalent terms to extract data from studies investigating this domain. Nine studies were found. First, EIF-related effects on kinetics, EMG and obstacle contacts have been poorly studied. Second, consistent and inconsistent results were found in the kinematic outcomes after EIF. Consistent results included reductions in stride duration and increased step width. Inconsistent results included gait velocity (no-effect vs increased), leading and trailing-foot vertical clearance (reduced vs increased) and horizontal distance from foot to the obstacle before obstacle avoidance (no-effect vs increased). These findings should be interpreted cautiously, however, due to the heterogeneity of the obstacle crossing and EIF protocols.
行走时遇到障碍物可能会很危险，这反映出失去平衡、绊倒和摔倒的风险更高。在内部资源有限的特殊情况下，例如疲劳状态，可能会影响越过障碍物时的表现，增加摔倒或事故的风险。因此，我们的目标是回顾实验性疲劳（EIF）对健康个体越过障碍物时步态参数的影响。我们系统地检索了 PubMed 和 Web of Science 数据库，使用“疲劳”、“障碍物穿越”及其等效术语来提取研究该领域的数据。发现了九项研究。首先，EIF 对动力学、肌电图和障碍物接触的影响研究得还不够充分。其次，EIF 后运动学结果存在一致和不一致的结果。一致的结果包括步幅持续时间缩短和步幅宽度增加。不一致的结果包括步态速度（无影响或增加）、引导脚和跟随脚的垂直间隙（减少或增加）以及在避免障碍物之前脚与障碍物之间的水平距离（无影响或增加）。然而，由于障碍物穿越和 EIF 方案的异质性，这些发现应该谨慎解释。
