BACKGROUND: The aim of this study is to investigate the relationship between temporal coordination and ground reaction force variables between both sides of lower limbs during vertical landing in athletes with functional ankle instability.
METHODS: Kinematics and kinetics were recorded as sixteen male adults with FAI performed a drop landing from 30 cm platform. The peak vertical force variables, coefficient of variation, dynamic postural stability index, and lower limb joints of hip, knee, and ankle were calculated.
RESULTS: The variables contrast sensitivity, peak vertical force time, loading rate, maximum flexion of knee and ankle, and temporal coordination of hip and ankle were significantly different between both lower limbs. In addition, the right leg significantly higher of CV (%) of temporal coordination, and stability index of anterior-posterior, vertical, and dynamic postural compared to the left leg.
CONCLUSIONS: This study suggests that greater impulse force can be delivered to the musculoskeletal system in individuals with FAI (proprioceptive deficit) of their dominant leg.
