261 – TSD250 (BPS-II) VMG transducer in the assessment of 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.

Associated Applications

• Exercise Physiology - Examine ventilation, oxygen uptake, carbon dioxide production, biopotentials, temp., and biomechanical signals simultaneously. Record wirelessly with BioNomadix.
• EMG: Electromyography - Record surface, needle, and fine wire EMG—or wireless EMG with BioNomadix. Use real-time integration tools for immediate analysis or use automated EMG analysis routines.
