What this Trial Is About
Anterior cruciate ligament (ACL) injury is a prevailing problem among sports participants, especially in non-contact sports. Studies have reported that 70-84% of ACL injuries are non-contact in nature, and movements like changing in direction while running, cutting and pivoting on a planted foot have resulted in a majority of ACL injuries. Even after ACL reconstruction (ACLR) surgeries, study has reported a 30-50% prevalence of developing patellofemoral joint (PFJ) pain in 1-2 years post-operation. Whole body vibration (WBV) therapy has been gaining attention as an effective method of training in recent years. It has been proved to have a positive effect on improving muscle strength, muscle activities, muscle power and loading during drop jump. Though duration of WBV may differ according to the effect of interest, several studies have had positive results with a 8 week WBV therapy in increasing muscle strength, proprioception, and post-ACLR knee functions. Further investigation on the underlying mechanism and possible application are to be continued to explore more possibilities with the WBV therapy.
