Excessive foot pronation during static standing, walking and running has been reported as a contributing factor for the development of medial tibial stress syndrome (MTSS). The motion of foot pronation consists of hindfoot and forefoot motion. However, no previous studies have investigated forefoot and hindfoot kinematics during walking and running in subjects with MTSS. The current study sought to compare hindfoot and forefoot kinematics between subjects with and without MTSS while walking and running. Eleven subjects with MTSS and 11 healthy controls (each group containing 10 males and one female) participated in the current study. Segment angles of the hindfoot and forefoot during walking and running barefoot on a treadmill were recorded using three-dimensional kinematic analysis. An independent t-test was used to compare kinematic data between groups. Subjects with MTSS exhibited significantly greater hindfoot eversion and abduction (p < 0.05) during walking and running than subjects without MTSS, significantly greater forefoot eversion and abduction (p < 0.05) during walking, and significantly greater forefoot abduction during running (p < 0.05). Hindfoot and forefoot kinematics during walking and running were significantly different between subjects with and without MTSS. For prevention and rehabilitation of MTSS, it may be important to focus on not only hindfoot but also forefoot kinematics during both running and walking. © 2019 Orthopaedic Research Society.

在静态站立、行走和跑步过程中，过度的足内旋被认为是导致胫骨内侧应力综合征（MTSS）发展的一个因素。足内旋的运动包括后足和前足的运动。然而，以前的研究并没有调查过 MTSS 患者在行走和跑步时的前足和后足运动学。本研究旨在比较 MTSS 患者和无 MTSS 患者在行走和跑步时的后足和前足运动学。11 名 MTSS 患者和 11 名健康对照者（每组各有 10 名男性和 1 名女性）参加了本研究。使用三维运动学分析记录了在跑步机上赤脚行走和跑步时后足和前足的节段角度。采用独立 t 检验比较组间运动学数据。与无 MTSS 患者相比，MTSS 患者在行走和跑步时后足外翻和外展（p<0.05）明显更大，在行走时前足外翻和外展（p<0.05）明显更大，在跑步时前足外展明显更大（p<0.05）。MTSS 患者和无 MTSS 患者在行走和跑步时的后足和前足运动学有明显差异。对于 MTSS 的预防和康复，不仅要关注后足，还要关注跑步和行走时的前足运动学，这可能很重要。
