Vibratory Stimuli, A Novel Rehabilitation Method for Preventing Post-Traumatic Knee Osteoarthritis
Abstract
The purpose of this study is to determine the acute effects of whole body vibration (WBV) and local muscle vibration (LMV) on quadriceps function, proprioception, and gait biomechanics in individuals with anterior cruciate ligament reconstruction (ACLR). We hypothesize that both forms of vibration will enhance the outcomes in manners that would potentially reduce the risk of developing post-traumatic knee osteoarthritis (PTOA). The primary goals for Year 4 were to complete data analysis and development of dissemination materials. We have completed testing in the entire sample of 75 participants, and have completed the primary analyses. We have been granted a no-cost extension for the project which we will use to finalize data analysis and dissemination materials. To date, the project has resulted in 3 peer-reviewed manuscripts and 8 conference abstracts, and we anticipate at least 1 additional manuscript will be submitted for peer review in the near future. The study has been highly successful. In particular, we have demonstrated that vibration acutely improves gait biomechanics linked to development of PTOA. Specifically, WBV increased the sagittal plane knee moment, an outcome that is consistently reduced following ACLR and is lower in patients who develop PTOA within 5 years compared to those who do not. Additionally, LMV reduced the vertical loading rate, which is greater in the reconstructed limb and is associated with cartilage structural and biosynthetic degradation.
