Vibration on the Quadriceps after an ACL reconstruction

The influence of local muscle and whole body vibration explored.

Quadriceps dysfunction occurs frequently after an anterior cruciate ligament reconstruction (ACLR) and might contribute to physical disability. Studies revealed activation deficits in the contralateral limb and showed impaired central influences on the quadriceps function, such as a reduced corticomotor excitability. Muscle strengthening has been shown to be often unsuccessful in restoring quadriceps function and thus novel approaches are needed.

This study investigated the novel approach of combining the squat exercise with local muscle vibration (LMV), whole body vibration (WBV) and compared the results to the squat exercise without any vibration. The group which had received the WBV, as well as the LMV group showed significant improvements of the quadriceps function compared to the group without vibration.
