Vibratory Stimuli: A Novel Rehabilitation Method for Preventing Post-traumatic Knee Osteoarthritis
This study will evaluate the acute effects of vibration (whole body vibration and local
muscle vibration) on quadriceps function, knee joint proprioception, and gait biomechanics
linked to osteoarthritis development in individuals with anterior cruciate ligament
reconstruction. Subjects will be randomly assigned to control (no vibration), whole body
vibration, and local muscle vibration groups, and the aforementioned characteristics will be
assessed prior to and following the respective interventions.

Quadriceps muscle dysfunction and proprioceptive deficits following knee injuries alter
walking gait biomechanics in manners that contribute to development of knee osteoarthritis.
Current rehabilitation techniques are minimally effective for addressing these complications
and preventing knee osteoarthritis. Anterior cruciate ligament reconstruction dramatically
increases the risk of knee osteoarthritis, and represents an ideal model for evaluating novel
rehabilitation techniques for preventing knee osteoarthritis.
Direct (local muscle vibration) and indirect (whole body vibration) vibratory stimuli enhance
quadriceps function and proprioception, and may improve rehabilitation and reduce the risk of
knee osteoarthritis. The purpose of this investigation is to determine and compare the acute
effects of whole body vibration and local muscle vibration on quadriceps function, knee
proprioception, and gait biomechanics in individuals with anterior cruciate ligament
reconstruction. The investigators hypothesize that vibratory stimuli will enhance quadriceps
function, knee proprioception, and gait biomechanics in manners that would reduce the risk of
developing knee osteoarthritis, and that whole body vibration and local muscle vibration will
produce equivalent improvements in these characteristics.
