Effects of the CREATOR Ankle Brace on Crural Muscle Activities in Some Kinds of Actions by EMG

This study investigated the effects of the ankle brace “CREATOR” on lower extremity muscles in performances by maximum amplitudes of the integrated electromyogram (IEMG).

Description
Summary:This study investigated the effects of the ankle brace “CREATOR” on lower extremity muscles in performances by maximum amplitudes of the integrated electromyogram (IEMG). Twelve female handball players performed four exercises, repeated side step, vertical high jump, standing long jump and pivot. Maximum amplitudes of all muscles with the brace tended to be less than those without it. Those of tibialis anterior in the repeated side step and pivot, medial gastrocnemius in all performances except for repeated side step and peroneus longus and peroneus brevis in the repeated side step were significant. Thus with the brace, subjects performed the same with less muscle activity than without it, and this brace prevented an ankle sprain against the side direction.
