AbstractThe aim of this study is to investigate foot posture pre- and post-tape application using static assessments and pressure plate analysis. Fifteen healthy participants [male n= 9, female n= 6, 28.50 ± 11.00 years, 1.71 ± 0.10 m, 80.50 ± 18.00 kg] were conveniently sampled to take part in this study. Participants were assessed statically in a seated, bipedal and unipedal stance through pressure plate analysis and measurements of the navicular drop, medial longitudinal arch angle (MLA) and tibiocalcaneal angle (TCA). Measurements were taken pre- and post-tape applications which included no tape application, Sham, Zinc Oxide (Z/O), Elastic Adhesive Bandage (EAB) and two K-tape applications. There was a statistically significant difference between MLA and tape application [F (5,10) = 282.90, p=<.001, ηp2 = 0.122]. Significant increase in MLA was found between the following results; Zinc Oxide vs. K-tape 1 [p=<0.001], Zinc Oxide vs. K-tape 2 [p=<.001] and Sham vs K-tape 2 [p=0.022]. Whilst significant decrease in MLA was found between the following results; EAB vs. Zinc Oxide [p=<.001] and EAB vs Sham [p=0.025]. There were no statistically significant results found between MLA and change in body position [F (2,10) = 90.65, p=0.101, ηp2 = 0.016]. Additionally, there was a statistically significant difference between TCA and position [H (2) = 37.21, p=<.001] as well as TCA and tape application [H (5) = 27.79, p=<.001]. Significant decrease in TCA was found between the following results; Bipedal vs. Unipedal [p=<.045], ε2 = -0.337], Bipedal vs. Seated [p=<.001], EAB vs. No Tape [p=<.035], EAB vs. Sham [p=<.001] and EAB vs. Zinc Oxide [p=<.001]. There was a significant increase in TCA in the following conditions; Sham vs. K-tape 1 [p=<.026] and Zinc Oxide vs. K-tape 1 [p=0.032]. Furthermore, there was a statistically significant difference between total contact area and position [H (2) = 207.269, p=<.001]. Significant decrease in total contact area were found in the following conditions; Seated vs. Unipedal [p=<.001] and Bipedal vs. Unipedal [p=<.001]. Significant increase in total contact area was observed when comparing Bipedal vs. Seated [p=<.001]. In conclusion, the MLA results suggests that clinicians could justify the use Zinc Oxide tape application over other taping conditions due to the results showing that application typically increased the angle, indicating a better postural support being given which could assist individuals with a pronated foot posture. In contrast, EAB and K-tape applications were seen to reduce the angle of the MLA which justifies a clinician in using these tape applications for an individual with supinated foot posture over other applications, in order to reduce the MLA. Furthermore, the TCA seen across all conditions provided values which indicated a hindfoot valgus/pronated position, it could be suggested that EAB tape application reduces the TCA result and therefore brings the hindfoot angle more towards a neutral position. Additionally, results have also shown how the change in body position influence total contact area of the foot. These results provide clinicians with a greater understanding as to how the foot posture changes under different loading conditions based on body position which hasn’t previously been reported in literature.
