To investigate the effect of foot pronation on the postural stability through measuring the dynamic balance including overall stability index (OAI), anteroposterior stability index (APSI) and mediolateral stability index (MLSI).
Forty participants from both sexes were selected from the Faculty of Physical Therapy, Cairo University, with a mean age of 23.55 ± 1.74 years. Subjects were divided into two groups: group A (8 males and 12 females) with foot pronation, and group B (9 males and 11 females) with normal feet. The Navicular Drop Test (NDT) was used to determine if the feet were pronated and Biodex Balance System was used to assess dynamic balance at level 8 and level 4 for both groups.
No significant difference was found in dynamic balance, including OAI, APSI and MLSI at stability level 8 (p> 0.05) but, there was a significant difference at stability level 4 (p< 0.05) between the two groups with lower stability in group A.
Foot pronation affects the postural stability at stability level four and not affects stability level eight compared with those in the control group.
通过测量包括整体稳定性指数（OAI）、前后稳定性指数（APSI）和内外侧稳定性指数（MLSI）在内的动态平衡，研究足内翻对姿势稳定性的影响。
从开罗大学物理治疗学院选取40名参与者，平均年龄为23.55±1.74岁。受试者分为两组：A组（8名男性和12名女性）为足内翻组，B组（9名男性和11名女性）为正常足组。采用舟骨下降试验（NDT）确定足部是否内翻，并使用Biodex平衡系统对两组在8级和4级水平评估动态平衡。
两组在8级稳定性时的动态平衡，包括OAI、APSI和MLSI，差异无统计学意义（p>0.05），但在4级稳定性时存在显著差异（p<0.05），A组稳定性较低。
与对照组相比，足内翻影响4级稳定性时的姿势稳定性，而不影响8级稳定性时的姿势稳定性。
