Effect of individual ankle taping components on the restriction of ankle external inversion moment

ABSTRACT

The efficacy of individual taping components to restrain ankle inversion sprain has not been fully understood to date. We aimed to clarify specific taping components that can effectively restrain the amount of angular impulse due to external ankle inversion moments during dynamic ankle motion. Nine participants with chronic ankle instability performed a side-jump with five taping conditions: stirrup, figure eight, heel lock, basketweave, and without taping (control). During the initial landing phase, angular impulses, plantar inclination angle of the whole foot, and plantar flexion angle of the midfoot and hindfoot were compared among these conditions. The basketweave was the only taping condition succeeded in significantly reducing plantar inclination angle of the whole foot, thereby inducing significantly reduced angular impulse due to external ankle inversion moment compared with the control. Although the stirrup and figure eight were found to significantly restrict the plantar flexion angle of the hindfoot and the midfoot, respectively, neither of these components could alter the plantar inclination angle of the whole foot. It was suggested that all the taping components are necessary to reduce the external ankle inversion moments. Certain components should not be used individually to alter the plantar inclination angle of the whole foot.
