The Effect of Subtalar Joint Antipronation Taping on the Dynamic Knee Valgus in Female Volleyball Players with Low Medial Arch

Before applying the tape, its length was measured by passing it over the areas on the foot where it would be applied. The tape was first attached to the medial side of the big toe, with tension in the direction of flexion and abduction of the toe. The ankle was then positioned in full plantar flexion. The tape was applied from the medial side of the foot towards the heel, wrapping around it, and then directed towards the sole. While the foot was in an inversion position at the navicular level, the tape was applied with maximum tension from medial to lateral and brought back to the sole. The remainder of the tape, with maximum tension, was applied from the sole to the dorsal side of the ankle, ending without tension at the proximal and lateral side of the leg. A second strip of tape, with maximum tension, was applied to support the medial longitudinal arch. The ends of the tape were placed over the malleoli without tension, aiming to reduce excessive pronation.

In the sham taping application, the length of the tape was measured by passing it over the areas where it would be applied. The tape was applied to the medial side of the big toe, but without tension, simply placed. Then, the tape was directed towards the sole of the foot, passing over the heel. At the navicular level, the tape was applied from medial to lateral, returning to the sole without tension. A second strip of tape was applied to the sole without tension. The ends of the tape were placed over the malleoli without stretching. Since no tension was applied, this application was only placed and has a limited effect on reducing excessive pronation.
