261 – TSD250 (BPS-II) VMG transducer in the assessment of isometric absolute muscle effort
Home>Application Notes>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.
Synchronizing Data from Multiple Participants Performing a dyadic experiment takes more planning than single-participant studies. Data must be tightly synchronized, equipment must remain inobtrusive, and the experimental paradigm drives the optimal setup. Join us to learn how to record high-quality synchronized data for a wide range of applications.
What You Will Learn: – How to synchronize data from two participants – Recording options: ECG, EDA, EEG, fNIRS, Video – Collaborative virtual environments – Data analysis techniques – Practical tips—and advice on working with children – New ideas about your research
