摘要

目的通过比较慢性踝关节不稳定（CAI）患者和对照组患者的前足和后足运动学，研究可改变的着地平台如何影响单腿着地时的足内运动，从而为以足部为重点的康复策略提供依据。主要结果测量参与者在三种方向（倒置、跖屈-倒立-内收和背屈-倒立-内收）和四种倾角（10°、12°、14°、16°）的平台上进行单脚着地。这些配置是根据先前的研究和安全限制确定的。结果 CAI 组的前足内翻（η2 = 0.32; p < 0.01）明显大于 CAI 组，后足外翻（ƞ2 = 0.183; p = 0.06）的组间差异不明显。方向和倾斜度对前脚掌运动有很大影响（η2 = 0.56 和 0.80，p <0.001）。明显的组别 × 区段交互作用（η2 = 0.24; p <0.001）表明 CAI 患者的前脚掌和后脚掌之间的运动形成了鲜明对比，而对照组中没有观察到这一现象。研究结果支持使用可修改的平台和多节足模型来指导有针对性的干预措施，以解决前足补偿问题并改善着地过程中的节段控制。

Effects of differing platform orientations on forefoot and hindfoot kinematics in chronic ankle instability during single leg landing

Objectives

To investigate how modifiable landing platforms influence intra-foot movement during single-leg landings, comparing forefoot and hindfoot kinematics between individuals with chronic ankle instability (CAI) and controls to inform segment-focused rehabilitation strategies.

Design

Cross-sectional.

Setting

Biomechanics laboratory.

Participants

20 university students, 12 with CAI, 8 controls.

Main outcome measures

Participants performed single-leg landing on platforms with three orientations (inverted, plantarflexed-everted-abducted and dorsiflexed-inverted-adducted), and four inclinations (10°, 12°, 14°, 16°). These configurations were based on prior studies and safety limits. Net frontal-plane movement of the forefoot and hindfoot was calculated across a 400ms window.

Results

The CAI group showed significantly greater forefoot inversion (η² = 0.32; p < 0.01) and non-significant group difference in hindfoot eversion (ƞ² = 0.183; p = 0.06). Orientation and inclination had large effects on forefoot motion (η² = 0.56 and 0.80, respectively; p < 0.001). A significant group × segment interaction (η² = 0.24; p < 0.001) indicated contrasting movement between the forefoot and hindfoot in CAI, not observed in controls.

Conclusion

Individuals with CAI demonstrated a less adaptive, segment-specific landing strategy. Findings support the use of modifiable platforms and multi-segment foot models to guide targeted interventions addressing forefoot compensation and improving segmental control during landing.

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
