The Immediate Effect of KINESIO TAPE® on Static Plantar Foot Pressure and Force in Young Females with Flexible Flatfoot: A Pilot Study

Background: Flatfoot is a condition brought on by trauma, persistent foot stress, obesity, and poor biomechanics. These factors result in the development of a flat foot, collapse of the foot arch, and malfunction of the posterior tibial tendon. This study aimed to assess the immediate effects of Kinesio Tape on static plantar foot pressure and force in young females with flexible flatfoot. Methods: A pilot study (pre-experimental study design) with a convenience sample of 20 female subjects from a university with flexible flatfoot (age = 20.1 ± 1.3 years, weight = 91.8 ± 14.4 kg, height = 162.2 ± 6.3 cm, BMI = 34.9 ± 5, foot posture index (FPI) = 8.8 ± 2.1) was selected. The TekScan MatScan® system was used to measure the static plantar forces and pressures, foot contact area, and the mediolateral displacement of COF over time while standing (Boston, MA, USA) before and immediately after the application of Kinesio Tape (KT). Results: While there were no statistically significant changes in the foot peak or total pressure, paired-sample t-tests showed a statistically significant reduction in foot contact area (p < 0.05) and a statistically significant increase in midfoot maximum force (p < 0.05) following the application of KT. Furthermore, after applying KT, there was a statistically significant decrease in the mediolateral COF velocity, indicating greater lateral displacement of COF (p < 0.05). Conclusions: The results of this study concluded that Kinesio Tape was a useful intervention method for immediately redistributing pressure and forces in young females with flexible flat feet.
