Purpose: It is essential to maintain dynamic stability during walking to perform daily tasks independently. The present study aimed at comparing the spatiotemporal parameters and the values of the vertical Ground Reaction Force (vGRF) as well as determining the time to reach them in ankle-sprain coper and healthy athletes during the stance phase of gait.
Methods: A total of 28 female university athletes were recruited in this cross-sectional study and assigned into two groups: ankle-sprain coper (n=14) and healthy control (n=14). The gait cycle analysis was then performed on a 10-m path, and the information related to the stance phase was recorded by a foot scanning device. The spatiotemporal parameters (gait line and contact time) and the values of the vGRF along with the time to reach them were subsequently obtained from each test. The repeated measures Analysis of Variance (ANOVA) was additionally used to analyze the data (P≤0.05).
Results: The study results revealed no differences between the injured and the healthy feet in the ankle-sprain coper group in any of the variables (P>0.05). As well, the spatiotemporal gait cycle parameters between the ankle-sprain coper group and the healthy controls were not significantly different (P>0.05). However, significant differences were observed between the ankle-sprain coper and healthy controls in terms of the variables of the vGRF in the mid-stance (F=5.25, P=0.03) and the time to reach the second peak of the vGRF (F=9.13, P=0.006).
Conclusion: The spatiotemporal gait parameters were not significantly different between the ankle-sprain coper and the control groups, but the vGRF in the ankle-sprain coper was greater than that in the control group. With regard to the correlation between the reduction in the vGRF and the secondary injury, it is recommended to pay much attention to this point in rehabilitation programs following the first injury in female athletes.

● The spatiotemporal parameters were not significantly different between groups.
● No differences observed in injured and healthy feet of coper group.
Plain Language Summary
Lateral Ankle Sprain (LAS) is the most common injury in people with physical activity. Chronic ankle instability is a pervasive term used to classify a person with mechanical and functional ankle instability. Among these, there are also people who do not experience recurrent ankle sprains after the initial injury, and are often referred to the "coper" group in studies. Walking is very important in daily life and its dynamic stability is essential for independence during daily activities. People with a history of LAS experience imbalance, increased lateral ankle pressure during stance phase of walking, and recurrent ankle sprain. Given the importance of ground reaction force and walking variables in the occurrence of injury, the purpose of this study was to compare spatiotemporal parameters of walking and vertical ground reaction force (vGRF) and time to vGRF values in the coper group and healthy control. 28 active female college students as coper ankle sprain(n=14) and healthy control (n=14) groups participated in the present study. The gait-test was performed on a 10-meter path and the information related to the stance phase was recorded by the foot scanning device. The spatiotemporal parameters and the values of the vGRF and time to reach them were obtained from each test. The results showed that the coper group did not differ from the healthy control group in spatiotemporal parameters. Unlike spatiotemporal parameters, the vGRF in the coper group was higher than in the control, which it can be the cause cartilage of the ankle joint damages. Due to the relationship between vGRF value and secondary injury reduction, training of right walking as the main part of rehabilitation programs can be one of the therapeutic goals to prevent the frequency of ankle sprain and re-injury in coper athletes.
