Research shows whole body vibration decreases medial tibiofemoral contact force in individuals post-ACL reconstruction, suggesting a strategy to reduce osteoarthritis risk.
Key Points
The research aims to investigate how whole body vibration affects tibiofemoral contact force during walking after ACL reconstruction.
Participants with unilateral ACLR were randomized into control, whole body vibration, or local muscle vibration groups.
Walking biomechanics were assessed before and after interventions.
Tibiofemoral contact forces and quadriceps muscle forces were compared using repeated measure ANCOVAs.
Medial contact force significantly decreased following whole body vibration (mean difference = -0.219, p = 0.001).
Lateral contact and total contact forces, along with quadriceps forces, remained unchanged after both interventions.
