Abstract

Background: Functional ankle instability (FAI) is a common condition that affects individuals who have experienced previous ankle sprains. Textured insoles and elastic ankle braces have been previously used as interventions to improve stability in FAI patients. However, the optimal combination of these interventions has not been fully explored. The objective of this study was to investigate the effects of different types of textured insoles and elastic ankle braces on the dynamic stability of individuals diagnosed with FAI.

Methods: The study involved 18 FAI patients who performed single-leg landing tasks with and without wearing an eight-band elastic ankle brace while wearing textured insoles with protrusion heights of 0 mm, 1 mm, and 2 mm. The dynamic posture stability index (DPSI) and its components in the anterior-posterior (APSI), mediolateral (MLSI) and vertical (VSI) directions were calculated from the ground reaction force collected from the Kistler force plate during the first three seconds of the landing tasks.

Results: A significant interaction was found between textured insole type and ankle brace for DPSI (P = 0.026), APSI (P = 0.001), and VSI (P = 0.021). However, no significant interaction was observed for MLSI (P = 0.555). With elastic ankle braces, textured insoles with 1-mm protrusions significantly enhanced anterior-posterior, mediolateral, vertical, and overall stability compared to textured insoles with no and 2 mm protrusions (P < 0.05). Without elastic ankle braces, textured insoles with 1-mm protrusions significantly improved the anterior-posterior (P = 0.012) and overall stability (P = 0.014) of FAI patients compared to smooth insoles.

Conclusions: The combination of textured insoles with 1-mm protrusion heights and an elastic ankle brace could enhance the dynamic stability of individuals with FAI, potentially mitigating the risk of ankle sprains.

纹理鞋垫和弹性支架对功能性踝关节不稳患者动态稳定性的影响。

背景:功能性踝关节不稳定(FAI)是一种常见的情况，影响到以前经历过踝关节扭伤的个体。有纹理的鞋垫和有弹性的踝关节支架以前被用作改善FAI患者稳定性的干预措施。然而，这些干预措施的最佳组合尚未得到充分探索。本研究的目的是探讨不同类型的纹理鞋垫和弹性踝套对诊断为FAI的个体动态稳定性的影响。方法:本研究纳入18例FAI患者，他们分别穿着突出高度为0 mm、1 mm和2 mm的纹理鞋垫，在有或没有佩戴八带弹性踝关节支架的情况下进行单腿着地任务。根据着陆任务前3秒从Kistler力板收集的地面反作用力，计算了动态姿态稳定指数(DPSI)及其在前后(APSI)、中外侧(MLSI)和垂直(VSI)方向上的分量。结果:有纹理的鞋垫类型与踝关节支架DPSI (P = 0.026)、APSI (P = 0.001)和VSI (P = 0.021)之间存在显著的相互作用。然而，MLSI未观察到显著的相互作用(P = 0.555)。与无突出物和2毫米突出物相比，使用弹性踝关节支架时，1毫米突出物的纹理鞋垫显著增强了前后、中外侧、垂直和整体稳定性(P)结论:1毫米突出物高度的纹理鞋垫与弹性踝关节支架的组合可以增强FAI患者的动态稳定性，可能降低踝关节扭伤的风险。

期刊介绍： Journal of Foot and Ankle Research, the official journal of the Australian Podiatry Association and The College of Podiatry (UK), is an open access journal that encompasses all aspects of policy, organisation, delivery and clinical practice related to the assessment, diagnosis, prevention and management of foot and ankle disorders. Journal of Foot and Ankle Research covers a wide range of clinical subject areas, including diabetology, paediatrics, sports medicine, gerontology and geriatrics, foot surgery, physical therapy, dermatology, wound management, radiology, biomechanics and bioengineering, orthotics and prosthetics, as well the broad areas of epidemiology, policy, organisation and delivery of services related to foot and ankle care. The journal encourages submissions from all health professionals who manage lower limb conditions, including podiatrists, nurses, physical therapists and physiotherapists, orthopaedists, manual therapists, medical specialists and general medical practitioners, as well as health service researchers concerned with foot and ankle care. The Australian Podiatry Association and the College of Podiatry (UK) have reserve funds to cover the article-processing charge for manuscripts submitted by its members. Society members can email the appropriate contact at Australian Podiatry Association or The College of Podiatry to obtain the corresponding code to enter on submission.
