Effects of Antipronation Taping on Single-Limb Stance Static Balance in Subjects with Pronated Foot-an Experimental Study

Aim of the Study: To investigate the effect of antipronation taping on subjects with pronated foot during single limb stance. Background: Abnormal foot pronation causes passive instability of the joints of foot. The pronated foot, therefore, is unstable during weight bearing. The effect of antipronation taping on pronated foot during single limb stance lacks evidence. Study Design: Single-group repeated measures design. Methodology: Ten subjects (3 men, 7 women) with pronated foot (navicular drop = 13.0 ± 3.7mm) participated in this study conducted at the Mary Varghese Institute of Rehabilitation, Christian Medical College, Vellore. The subjects were asked to stand in unilateral stance on the dominant leg on the force platform of the balance master for 10 seconds. The degree of sway in the anteroposterior (AP) axis, the transverse axis and the velocity of moment (mm2/s) were calculated before and after application of antipronation taping. A mean of three recordings was taken for analysis. Results: There was a significant reduction in the scores of velocity of moment, anteroposterior sway and mediolateral sway after taping of the pronated foot. (P-value = 0.005) Conclusion: The study shows that antipronation taping improves single limb stance balance in subjects with pronated foot.
