New VMG report: isometric absolute muscle effort

Vibromyography (VMG) has distinct benefits over EMG in that the recordings much more accurately reflect absolute muscle effort up to 100% maximum voluntary contraction. Correspondingly, VMG can be used to both evaluate muscle changes over time in a given individual or to compare between two populations the muscle effort required to complete a specific task. The ability to discriminate muscle effort changes depends on the precision and accuracy of the VMG under these two scenarios, that is, the intra-assay accuracy and variability and the inter-assay accuracy and variability. Here, we address the inter-assay variability of VMG recordings in healthy adult men, focusing on isometric contraction of an upper extremity muscle.
