Altered leg muscle activity in volleyball players with functional ankle instability during a sideward lateral cutting movement
OBJECTIVES: To study the activation patterns of tibialis anterior, peroneus longus and
gastrocnemius lateralis muscles during a lateral shuffle maneuver in volleyball players with
functional instability of the ankle joint. DESIGN: Observational case-control study. SETTING:
Research laboratory. PARTICIPANTS: Sixteen players with functional instability and 18
matched controls. MAIN OUTCOME MEASURES: RMS values of tibialis anterior, peroneus
longus and gastrocnemius lateralis muscles for the 50 ms before initial ground contact …
