A comparative study of whole body vibration training and conventional training on knee proprioception and postural stability after Anterior Cruciate Ligament reconstruction


British Journal of Sports Medicine. Vol. 42(5). pp: 373-378. 2008


The aim of this study was to investigate and compare the effect of a 4 weeks period of Power Plate training and conventional physiotherapy on the rehabilitation after Anterior Cruciate Ligament (ACL) reconstruction. Twenty male athletes who underwent ACL reconstruction surgery 3 months before participated in this study. The subjects performed postural stability tests (with eyes open and closed) and a knee joint reposition test. These are standard tests, used to measure postural control and balance. The improvements found were significantly greater in the Power Plate group than in the conventional therapy group.

Conclusion: The improvement of postural stability in the Power Plate training group, was significantly greater than that of the conventional training group. The issue most patients have trouble with after ACL reconstruction is the decreased anterior-posterior stability. The Power Plate group showed a great improvement in anterior-posterior stability, causing the researchers to conclude that Power Plate training may be a very useful tool to expedite rehabilitation after ACL reconstruction.
