The improvement of postural stability in Power Plate training group, performed on a Power Plate was significantly greater than that of the conventional training group. There was a significant improvement in all knee reposition tests of Power Plate training group in both knees, except in one condition. The issue most patients have trouble with after ACL reconstruction is the decreased anterior-posterior stability. The Power Plate group showed a substantial 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.
Proprioception is the conscious perception of limb position in space. There are many proprioceptors (sensory nerve receptors) located in the anterior cruciate ligament (ACL). ACL injuries reduce proprioceptive ability and postural stability. The aim of this study was to compare the effects of a Power Plate training program and that of conventional therapy treatments on knee proprioception and postural stability in ACL reconstructed subjects.
A total of 20 male athletes who underwent ACL reconstruction surgery participated in this study. The participants were randomly allocated to a Power Plate group (10 subjects) or a conventional therapy group (10 subjects). Both groups participated in 12 training sessions within one month (3 times a week). The Power Plate group performed prescribed Power Plate exercises (see fig. 2+3), and the conventional therapy group performed conventional strength exercises (hip abductors, adductors, flexors, extensors, leg press, leg curl and squat). Both groups performed a progressive schedule.
