262 – VMG to assess quad-hamstring activity after ACL tear

VMG provides a convenient means for assessing rehabilitation progress following sports injuries such as ACL tears due to its ability to be utilized under conditions which reflect the multi-segment, closed-chain activities associated with functional activities.

That VMG provides both an absolute and reproducible assessment of muscle effort permits both right/left comparisons within an individual, as well as the opportunity to track rehabilitation progress over time where left/right comparisons are inappropriate or not possible.

Vibromyography (VMG) has distinct benefits over dynamometry in that VMG recordings reproducibly reflect absolute muscle effort up to 100% of maximum voluntary contraction. Correspondingly, VMG can be used to simultaneously evaluate individual muscles (e.g. antagonistic muscle pairs) either over time or to identify left/right differences. This application note addresses how VMG can be used to assess quadriceps rehabilitation progress in a young adult male following ACL reconstruction.
