Vibromyography to Assess Quad Rehab After ACL Tear

A new application note for the Vibromyography transducer (TSD250) addresses how VMG can be used to assess quadriceps rehabilitation progress in a young adult male following ACL reconstruction. 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 […]

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. […]

Pulse Wave Analysis in small rodents Researchers at the R&D lab of the pharma company NicOx in Italy recently presented results from their study of PWA and Augmentation Index (AIx) in rats. A presentation was made at the last European meeting on Hypertension. “Beneficial Effect of Nitric Oxide on Large Arteries in Hypertensive Rats”. C […]

Vibromyography for Length-Tension Curves

To date it has been difficult to characterize the length-tension curve for a specific muscle. However, recent developments in the application of vibromyographic (VMG) technology to assess muscle effort permit an accurate determination of length-tension curve, thereby permitting accurate diagnosis and rehabilitation of muscle. Click for the full applicaton note Using Vibromyography to obtain length-tension curves […]

MRI Gradient Artifact Removal for ECG and EMG

New Methodology Removes Artifact      fMRI, MRI, Magnetic Resonance Imaging BIOPAC announces a new method to remove gradient artifact from physiological data recorded inside a functional MRI. The new technique allows researchers to record ECG, heart rate and R-R interval data from a subject while the MRI is taking images. The same technique also significantly improves […]
