The purpose of this study is to determine and compare the acute effects of whole body vibration and local muscle vibration on quadriceps function, proprioception, and gait biomechanics in individuals with anterior cruciate ligament reconstruction. We hypothesize that both forms of vibration will equally enhance quadriceps function, proprioception, and gait biomechanics in manners that would potentially reduce the risk of developing knee osteoarthritis. While the specific aims will not be realized and cannot be analyzed until the studys completion in Year 3 due to the single-blind randomized controlled trial design, Year 1 of the project was highly successful regarding progress toward the study aims. The primary goal for Year 1 was to recruit and enroll the first cohort of 30 subjects. September 25, 2016 will mark the 1-year anniversary of HRPO approval and initiation of research activities in earnest. To date we have enrolled 19 subjects who have completed all testing and 1 who is currently participating, and are in the process of scheduling have scheduled 8 additional potential subjects for the initial screening session. These data are in agreement with the target enrollment rate of 6-8 subjects per quarter specified in the SOW. There have been no unanticipated problems, and data collection has proceed as planned.
