Background: Foot as the most distal segment of the lower extremity has an important role in postural control strategies. Postural stability and dynamic balance is the base of all high level activities that influence by different factors. Therefore, the best sports performance followed by the best dynamic postural stability. Purpose: In this study we decided to determine if kinesio taping alter the foot dynamic stability and improve its dynamic balance in sports performances. Methods: In this semi experimental study, thirty-one healthy athletes participated voluntarily. They were 20-30 years old without repeated lower extremity injury in the past 3 months. They assigned to 2 groups depending on foot type, as defined by navicular drop measures: pronated (≥10 mm) and neutral (5-9 mm). Dynamic postural stability measured by star excursion balance test (SEBT) on the dominant leg in 8 directions. Each subject asked to maintain a single leg stance on the dominant leg and reach to the furthest point on each line with the opposite leg and the distance was recorded. They performed each test and condition 3 times, before and after taping. Kinesiotaping of dominant foot was 8shape and from lateral to medial side of the foot, to stimulate the mechanoreceptors. The average of 3 reaches of each direction was calculated and all scores were normalized to the subject's height (variable [cm]/height [cm]) before analyses. We used Paired T-test to analysis the data with the alpha level was set at p=0.05. Results: Dynamic postural stability was significant difference after kinesio taping in each group, specially pronated foot. There were significant differences in anterior (P = 0.010), posterior (P = 0.025) and posterolateral directions (P = 0.000) in neutral foot posture, also anterior (P = 0.042), anteromedial (P = 0.005), posterior (P = 0.007) and posterolateral directions (P = 0.039) in pronated foot posture. Conclusion(s): Our results suggest that kinesiotaping can improve dynamic postural stability in both foot types by stimulating the neuromuscular control system. Therefore it can be the proper method to improve dynamic stability in sport, without foot type consideration. Implications: Improving dynamic postural stability is a main goal to prevent sport injuries and improve sport performance that gains by taping, independent to the type of foot.
