Abstract
Background and Aims: The ankle joint is the last part of the lower limb chain, which has an important role in providing stability and movement. Ankle instability is one of the most common injuries among athletes. Chronic ankle instability is defined as a history of at least one ankle sprain, frequent ankle sprains and a feeling of giving way . Biomechanical changes, sensory-motor defects and neuromuscular disorders have been reported in people with chronic instability . One of the most important structural abnormalities in the foot is the decrease in the height of the medial longitudinal arch when bearing body weight, which causes deformity in the ankle and its pronation . Deformation of the arch, as measured by navicular height and drop (ND), was linked to lower-extremity musculoskeletal injuries . This study was conducted to compare navicular drop between female athletes with chronic ankle instability and healthy.
Methods: This is a quasi-experimental and comparative study. 15 athletes with ankle instability and 15 healthy athletes, aged 18–30 years old, volunteered to participate in this study. The navicular height in standing and sitting positions and the navicular drop were measured and used to determine the effect of chronic ankle instability on the foot medial longitudinal arch. The Kolmogorov-Smirnov test approved the normality of the data distribution and then an independent t-test was used to compare variables between groups.
Results: The results of the independent t-test showed that there is no significant difference in the navicular height in standing and sitting positions or the navicular drop between the healthy and ankle instability groups (P≥0.05).
Conclusion: According to the results of the present study, it seems that ankle instability has no effect on the navicular height in standing and sitting positions or the navicular drop. Probably, muscle damage caused by ankle instability could not affect the condition of the soles of the feet.
