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.

Experimental: Whole Body Vibration
Subjects will receive whole body vibration (30Hz, 2g) applied continuously for 1 minute. This exposure will be repeated 6 times with 2 minutes of rest between exposures.
Device: Whole body vibration
Experimental: Local Muscle Vibration
Subjects will receive local muscle vibration (30Hz, 2g) applied continuously for 1 minute. This exposure will be repeated 6 times with 2 minutes of rest between exposures.
Device: Local muscle vibration
No Intervention: Control
Subjects will perform the same procedures as the experimental groups with the exception that no vibratory stimulus will be applied.
