Given the importance of recognizing athletes with chronic ankle instability for rehabilitation clinics, foot pressure variables are essential parameters in the biomechanical analysis of the gait. This study aimed to determine the effect of kinesio tape application on plantar pressure variables in individuals with functional ankle instability. This quasi-experimental study included 29 men (24.5±2.27 years) with functional ankle instability selected using convenience sampling. A 15-meter path was provided for the subjects to walk. A foot scanner was installed 10 meters from the beginning of the route. Subjects were asked to walk 15 meters along this route. The kinesio tape was applied to the tibialis anterior, gastrocnemius, and peroneus muscles. After 20 minutes, Re-gait test was performed. Foot pressure data were recorded during walking. Plantar pressure variables, including peak plantar pressure distribution, the center of pressure, rearfoot inversion/eversion, forefoot supination, and pronation were measured before and after kinesio tape. No significant differences were found between the ten regions. The highest pressure was monitored in region 5 (third metatarsal) equal to 19.45 kPa, the lowest pressure was observed in the middle metatarsal region (second to the fifth toe) equal to 4.85 kPa. The use of kinesio tape affects on the fifth and middle metatarsus. The use of kinesio tape in people with ankle sprains can prevent the ankle from being too exposed to the pronation and keep the foot in supination, which is essential. Stimulation of mechanical receptors in the arch of the foot and around the ankle by kinesio tape can effectively increase the dynamic stability of the ankle.
